Best Practices For Mobile App Security in 2020

Have you ever heard about hacking of a mobile app? What does it mean? How do mobile apps get hacked? If you need to know all this, go through below-

Building a revolutionary mobile application is just the initial phase in mobile application development. There are thousands of mandatory processes that follow app development. One of them is the security of mobile apps. Here we will analyze the essential mobile app security practices that you should implement after the completion of development.

In the last few years, we have seen how the mobile application development industry has developed and hence have cybercrimes. These crimes have led us to a stage where it is not possible to submit an app to Play Store or App Store without taking certain measures to secure it. However, getting towards what the safety measures involve, we first need to know why there is a requirement for taking these actions and what are the potential application security issues that plague the mobile application development industry. There is still more to mobile application security than safeguarding them against malware and threats. Let us recognize some of the OWASP mobile application security threats to understand the safety measures better.

Need Of Mobile App Security: Potential Threats

Mobile app security

The threats that present themselves in the application development world are malicious. With the use of basic steps to secure a mobile application, these threats can be solved. Let us explore what are the significant risks to mobile application security.

1. Faulty server controls:

The communications that occur between the application and user outside the mobile phone device happen via servers. Such servers are main targets of hackers all through the world. The main purpose of the vulnerability of a server is sometimes developers ignore the necessary server-side security into account. This may occur because of a lack of knowledge about security considerations for mobile applications, little spending plans for security reasons, or the vulnerabilities caused because of cross-stage development.

This may occur because of an absence of information about security considerations for mobile applications, small budget plans for security purpose, or the vulnerabilities caused because of cross-platform development.

Solution:

The most important step in protecting your servers is to scan your applications with the help of automated scanners. These scanners can be used by hackers to uncover vulnerabilities in your applications and exploit them. Automated scanners will surface the normal issues and bugs which are easy to solve.

2. The absence of Binary protection:

This is one of the prime OWASP application security issues to address because there is an absence of Binary protection for a mobile application, any hacker or an adversary can easily reverse engineer the application code to introduce malware. They can also redistribute a pirated app of the same and infuse it with threat too. All of this can prompt to critical issues, for example, data theft and harm to brand image and resultantly revenue loss.

Solution:

To protect Binary files, it is necessary to deploy binary hardening procedures. As a part of this strategy, binary files are analyzed and accordingly modified to protect them against normal mobile application security threats. This technique fixes the legacy code without including the source code at all. It is vital to ensure security coding for the identification of jailbreaks, checksum controls, debugger detection control and certificate pinning while working on mobile application security processes.

3. Data Storage Insecurity:

Another enormous loophole common in Mobile application security is the absence of a safe data storage system. Truth be told, it is common for mobile application developers to depend upon client storage for internal data. During the possession of a mobile device by a rival, this internal data can be effortlessly accessed and used or manipulated. This can prompt a few crimes like theft or PCI (external policy violation).

Solution:

One of the application safety measures to consider here is to build an extra encryption layer over the OS’s base-level encryption. This gives an enormous lift to data security.

4. Inadequate protection for Transport layer:

The transport layer is the pathway through which data transfer takes place between the client and the server. Any hacker can access internal data to steal or modify it, if the proper mobile application security standards are not introduced. This leads to severe crimes like identity thefts and frauds.

Solution:

To strengthen transport layer security, you should incorporate SSL Pinning in iOS and Android applications. Alongside this, you can use industry-standard cipher suites rather than regular ones. Moreover, avoiding the exposure of user’s session ID because of mixed SSL sessions, alerting the user in case of an invalid certificate, using SSL versions of third-party analytics are normal practices which can save the users from a hazardous breach of security.

5. Unintended Leakage of data:

Unintended data leakage happens when critical mobile applications are stored in vulnerable locations on the mobile device. For instance, an application is stored where it can get accessed by other applications or devices which ultimately result in the data breach of your application and unauthorized data usage.

Solution:

Examining common data leakage focuses, such logging, application background, caching, Browser cookie objects and HTML5 data storage. In the wake of seeing the general threats which plague all the mobile applications and some of the Best mobile application security practices to follow for avoiding these issues, let us proceed onward to the particulars about the Android and iOS mobile application security.

How to Make Android Apps Secure?

1. Encryption of data on External Storage –

Generally, device has a limited internal storage limit. This disadvantage usually suppresses users to use external devices, for example, hard disk and flash drives for protecting the data. This data comprises sensitive and confidential data also. Since the data stored on the external storage device is easily accessible by all the applications of the device, it is essential to save the data in an encrypted format. One of the most broadly used encryption algorithms by mobile application developers is AES or Advanced Encryption Standard.

2. Using Internal Storage for Sensitive Data –

All the Android Applications have an internal storage directory. And, the files stored in this directory are more secure because they use MODE_PRIVATE mode for file creation. Basically, this mode ensures that the files of one specific application can’t be accessed by other applications saved on the device. Along these lines, it is one of versatile application verification best practices to center upon. Along these lines, it is one of mobile application authentication best practices to focus.

3. Using HTTPS –

The communications take place between the application and the server should be over HTTPS connection. Various Android Users are connected with several open WiFi networks in public areas and using HTTP rather than HTTPS can leave the device vulnerable against numerous malicious hotspots that can easily modify the contents of HTTP traffic and make the device’s applications behave unexpectedly.

4. Using GCM instead of SMS –

When Google Cloud Messaging or GCM didn’t exist, SMS was used so as to push information from servers to applications however today, GCM is widely used. But, if you have not switch from SMS to GCM, you should. This is because SMS protocol is neither safe nor encrypted. On it, SMS can be accessed and read by some other application on the user device. GCM communications are authenticated by registration tokens which are consistently refreshed on the client-side and they are authenticated using a unique API key on the server-side. 

Other significant mobile application development security best practices can incorporate, Validation of User input, Avoiding the need for personal data and use of ProGuard before publishing the application. The Idea is to secure application users from as much malware as possible.

How to Make iOS Apps Secure?

1. Storage of Data –

To more simplify your application’s architecture and improve its security, the most ideal path is to store application data in memory rather than writing it it on a disk or sending it to a remote server. In spite of the fact that if storing the data locally is your sole choice, there are different approaches:-

2. Keychain:

The best place to store less amount of sensitive data that doesn’t require frequent access is Keychain. Data which is stored in keychains is managed by the OS but it isn’t accessible by some other application.

– Caches: If your data doesn’t need to be backed up on iCloud or iTunes then you can store the data in the Caches directory of application sandbox. – Defaults system: The default system is a helpful strategy for storing a lot of data.

3. Networking security –

Apple is popular for security and privacy policies it offers. And for quite a long time, it has worked to reach this level. A couple of years back, Apple had introduced App Transport Security which implements third-party mobile applications to send network requests over a more secure connection, i.e., HTTPS.

4. Security of Sensitive Information-

Most mobile applications use sensitive user data, for example, address book, location, and so on. But, as a developer, you have to ensure that all the data that you’re asking the user for is, in fact, necessary to access and more significantly, to store. So, if the data you require can be accessed through a native framework, at that point it is not necessary to duplicate and store that information. We have now observed both Android and iOS mobile application security Practices for a Hack-Proof App. But no development can be so easy as it is written about. There are always some challenges which are faced during a process. Let them push ahead and learn about the challenges which are faced by developers during best mobile application security practices.

Challenges Associated With Mobile App Security-

There is a demonstrated record of how vulnerable mobile applications can be if not enough measures are taken for their security from external malware. The following are the challenges that can arise whenever the mobile application security testing isn’t completed as per the requirement.

1. Device Fragmentation –

Top 5 Technologies To Build Microservices Architecture

Microservices are achieving popularity in the market as organizations move in the direction of building complex and larger applications that can be segregated and handled as a compilation of smaller services. There has been an increasing number of people hoping to upgrade their traditional monolithic systems into a sequence of single independent microservices. The basic question that strikes your mind is, Which is the best language to be used while developing microservices for your next project?

You can use different technologies dependent on what best serves the purpose of your microservices. Here we will see some programming languages that have the features and libraries, which will help you in getting your job done. But before that, let us see, what is microservices architecture?

You can also know- Microservices vs. Monoliths: What’s the Right Architecture for your Software?

What is Microservices Architecture?

Microservices architecture is a development methodology wherein you can fragment a single application into smaller services, each one executing in its own process and interacting with lightweight mechanism. The microservices are developed around business capabilities, which are independently deployable with automated deployment mechanism. The microservices architecture needs an absolute minimum of the management of these services, built-in various programming languages and uses various data storage technologies.

Reasons to Migrate to Microservices Architecture-

• In a monolithic architecture, for a large application, it is difficult to penetrate the complexity and tough to deal with the code.
• Applications require broad manual testing so as to grasp the effect of alteration.
• The whole application requires to be deployed again even for a small change.
• Large applications with monolithic architecture can slow down the start-up time.

Benefits of Microservices-

1. Easier Process Adoption–

With a microservices architecture, new technology, and process adoption become easy.

2. Small Modules–

It is simple for developers to develop and maintain because the application is broken into smaller parts.

3. Independent Scaling –

Every module in microservices can scale freely through-

                  -X-axis scaling – by cloning with more memory Or CPU

                  -Z-axis scaling – by size using sharding

4. DURS –

Each service in microservices architecture can be autonomously DURS (Deployed, Updated, Replaced and Scaled)

5. Unaffected-

Even the failure of a single module won’t influence the rest of the app.

Microservices ensure increased the autonomy of development teams (speed to market), better fault isolation (reliability), reusability and scalability.

5 Cool things to consider before you update your mobile app

Many businesses require mobile apps. And these apps go through the life cycle that involves numerous updates. While popular mobile apps should be updated regularly, applications that haven’t been successful at capturing the focus of a large audience can easily make do with monthly updates. The process of mobile app update is a challenging one. Fixing bugs, making changes in design, checking application functionality, updating codes- these are tasks that require both time and dedication. Businesses and application developers, specifically, should give due thought to application updates. Here we will try to answer the greater question that is, how to approach application updates?

Also know- 7 Signs that indicate your mobile app needs a major update.

5 Things to Keep in Mind Before You Update Your Mobile App-

1. Is frequency important?

The frequency at which you update your application is really important. Regular updates of your application will help both your team and also users. A well-performing application must be updated at least once per week. If you already have a lot on your platter and can’t squeeze an application update, you should update the application at least once every month. There are different parameters businesses must remember while they are experiencing this process. If you have a business that is influenced by seasonal changes, your application must update the changes according to this. Thus, before starting with the process of an application update, businesses must ensure that they have enough content to give their users. Most businesses don’t think more about content. Great content increases both engagement and retention. If you wish to make your application effective, you should discover new approaches to make your application more interesting and user-friendly.

2. Should you work out a balance?

It is important for businesses to work out a balance between smaller and larger updates. App updates are frequently driven by feature releases. Businesses may decide to do an application update when they either have a huge update or a smaller one. Larger updates are difficult to deal with. Sometimes, these may even involve a long time of work. In such a case, the question is- how should businesses achieve a balance?

The appropriate answer is simple- try to fit in features that can be accommodated in a two-week development cycle. Features that take around two weeks of development really take about a month to go live. This is basically because the process of application updates does not only include development but also testing. But, in some cases, businesses may feel compelled to induce features that are very complex. When this occurs, businesses can handle the current issue by first doing smaller updates and planning for the bigger one in advance. While some application developers are working on the smaller update, businesses should allocate more resources to the larger update. This way, an application update would undergo two releases- first one, a smaller one followed by the larger one for which work has been going on for months.

Why we have to update our mobile apps regularly?

Most well known mobile apps update around once in a week or 4 times a month and as they are popular they can get away with that kind of schedule (consider Messenger, Instagram, Facebook, and so on) because users won’t worry about them however not all mobile application developers will have the equivalent chance. Updates are important to maintain your application and mobile application development to include new features that enhance user engagement.

Know more about- 5 Cool things to consider before you update your mobile app.

New Updates may be an additional reason to update, but neglecting to get the recent version of an application can set you and your device at risk. It may seem like developers update your applications over and over again, yet it’s important to make. It’s necessary to have a great app rating. Among the top 100 free apps, the middle application rating was 4.7, and just 9 mobile applications had a rating below 4.0. With the top 100 grossing applications, the lowest application rating was 3.9, and just 6 applications had a rating below 4.2.

The middle number of days between updates for the whole data collection is 8.75 days, and the most basic difference is 7 days. This shows most free applications start to get updates each week. The best mobile application development company continually uses the latest features that will be compatible with the latest updates.

We can list the reasons that clarify an update and then define the choice of each one of them.

7 Reasons why we have to update our mobile apps regularly-

1. Stay with Latest Technology- 

The main reasons to regularly update the mobile apps are to keep up with advances in hardware and software. Each point the OS of a device has updated, the chances are sure that you will require an update in your application. If your mobile apps are connected with Google Pay, Apple Wallet or Apple Maps/Google Maps, you will require connecting notified with updates to these platforms to ensure that their connection with your application remains seamless.

Have you noticed the recent increase in the application of Google Pay, Apple Pay, Samsung Pay, and Android Pay? They are fast, more advantageous and security is high. Numerous retail applications now offer it. If you also run a retail mobile application you’re still to incorporate into your system, you may already be losing a few users.

How To Protect Your Source Code IP When Outsourcing?

Software development outsourcing is very common these days as it has some benefits for the customer – lower costs, access to professional brain power regardless of their location, shorter development time because of getting a full team immediately. 

When outsourcing your project development, you will reveal your thoughts and innovations to your partner. Normally, you might be worried about their protection. There are various things you can do to strengthen the security of your property rights. However, the most important thing is choosing the right partner. Do consistently check the reputation of the development company you are intending to contract. Read the reviews, browse the portfolio, take a look at the projects the company has completed. This research can help you to choose whether the company deserves your trust.

At the same time, even with a good faith partner, there are still a few measures you should take to protect IP when outsourcing work to an application development company. We have put together a short checklist that you can use when planning the strategy of protecting your intellectual property. Before that let us see what is IP right for software?

Also know- Why should you outsource software development?

What is an IP right for Software?

IP (Intellectual Property) rights ensure that creative work, which is treated as an asset is legally owned or protected by a company. IP right for software is software or code protected by law under a software patent, copyright, trademark or trade secret. If IP protection is at your highest priority, here are some best practices to avoid negative repercussions from external risks.

Weigh the Intellectual Property Risks-

Enterprises share some IP related to processes, technologies, and applications with their service partners. The sharing of sensitive data raises some security concerns. These concerns can be reduced with strong planning, however nothing helps more than anticipating prematurely what the potential risks are:

Risk 1: Misuse of Sensitive data-                                 

The employees who access your sensitive data may unveil the data. This secrecy rupture may result in stealing source code, credit card fraud, Refund Fraud, Selling of the client’s database to competitors, and identify theft.

Risk 2: Idea or Source Code leaks-

The partnering company may have your competitors as its clients. Developing a part of code or creative idea for your product sometimes discovers its way into the competitor’s product as well.

Risk 3: Improper Proprietary Information Handling-

You can’t expect that everybody should treat your IP rights, data security, and confidentiality as a top priority like you do.

Risk 4: Ownership of Source Code IP-

The most significant resource that everyone considers is the source code, created or improved during the contract. Nobody wants to lose source code IP ownership in their preexisting works due to their partner made some enhancements. The service provider will most likely claim the ownership of the source code or technology enhancements and will demand ownership of any portion of existing work, related with those improvements.

But don’t worry, we have several ways to protect your source code IP leaks ad business.

How to Manage your Source Code IP Leaks Concern?

1. Choose the Right Partner-

You can secure your IP before the first line of your code is written. Choose your service Partner cautiously and work just with a reputable organization that operates under a reliable legal framework. You should give priority to countries like US, Germany, India and Japan, where the security practices are ensured with the developed legal system. India has different laws covering the whole areas of IP. It is a participant to a few international treaties in intellectual property rights.

You can decide to work with based on their portfolio, testimonials and past clients’ references. Reputable vendors will have no issue providing you all the details you request. Working with experts built on integrity will fundamentally reduce the chance of fake dealing and the source code IP theft.

2. Vendor Security Audit-

This shows the care that your partners took in safeguarding your IP assets. Knowing more about your vendor’s work can give you an insight into their safety and security practices.

• Their workstations are protected by Firewall and UTM systems
• No removable media is allowed in & out of the premises
• Unauthorized access to workstation and PCs is prohibited
• A Backup & recovery Policy is in place

Your risk-benefit analysis can show how well the legal infrastructure of the country will protect your IP rights. The employees of the organization are bound by an agreement with clauses to protect Data security, IP rights, Non-Solicitation, Confidentiality, and Non-Disclosure.

3. Sign an NDA-

NDAs, or Non-Disclosure Agreements, are generally signed at whatever new partners come into the relationship where intellectual property is concerned. If you are working with outsourcing  providers, sign an NDA with each of them.

Generally, an NDA should define the following points:

The parties that agree to non-disclosure of confidential information- 

The agreement must obviously refer to both your organization and the outsourcing service provider. Also, NDAs can be mutual or unilateral. With mutual NDAs, the both parties hope to disclose confidential information to each other, while with unilateral ones just one party (typically the customer) discloses the data that is considered to be confidential.

The information that is classified as confidential- 

Both parties signing the agreement must realize what data isn’t to be disclosed. In this manner, whenever any conflict emerges, the agreement will serve as the basis for its resolution.

The scope of obligations-

A non-disclosure agreement should explicitly state what actions it forbids – copying, duplicating, reverse engineering, distribution, etc. By including all possible means of information disclosure, you will ensure strong protection.

The exclusions from the obligations-

Most NDAs contain a clause saying that the two parties will be released from the liability if they unveil the private data if it was received from other public sources or before the agreement was signed.

The duration of the agreement and the obligations-

Generally, NDAs are valid for some years (including the complete time of the project development plus more). Regardless, ensure that when the agreement term expires — you will just drop the non-disclosure obligations while your IP rights remain.

Most IT development companies sign individual NDAs with each of their employees having access to the project data. This is an excellent practice, as it strengthens the security of your IP. Ask your partners whether they have such a policy within their organization before starting the project together.

4. Use Non-competence Agreement-

Together with the NDA, the Non-competence Agreement (NCA) with the service providers can prevent the revealing of your IP assets to the competitors. The idea is to keep the employees from revealing your prized formulas to your potential competitors. Basically, you get dedicated employees dealing with your project restricting them from working on other projects. In any case, NCA typically has a reasonable time frame as it can limit the company from taking future projects even after it has completed your projects.

5. Share Information Selectively-

Another simple approach to secure the source code and your idea is to be particular with what you are sharing. Clarifying the entire thought will be imperative in specific situations while outsourcing your development, but you don’t have to go in detail than necessary. Confine your specifications to the limit of the project requirements.

6. IP Protection with Carefully Crafted Contract-

Top 10 mobile app security tools to use in 2020

Mobile technology and Smartphone devices are the two famous terms that we frequently used in this world. We use smartphones for not only calling facilities, but also for Money transactions, clicking pictures, files/images transfer by bluetooth, GPS, Wi-Fi and so on. There are different reasons to say why mobile application security testing is necessary. Few of them are – To prevent fraud attacks on the mobile application, virus or malware infection to the mobile application, to prevent security breaches, and so on.

So from a business point of view, it is necessary to perform security testing.  However most of the time testers find it troublesome since mobile applications are focused on multiple devices and platforms. So tester requires a mobile application security testing tool which ensures that the mobile application is secure. Here we will discuss some mobile app security tools to use in 2020.

Top 10 mobile app security tools to use in 2020-

1. Zed Attack Proxy-

The OWASP ZAP is one of the world’s most popular mobile application security testing tools that is free to use and is effectively maintained by hundreds of volunteers around the world. This tool is simple and also easy to use. Prior it was used just for web applications to discover the vulnerabilities however right now. All the testers use it for mobile application security testing. ZAP supports sending malicious messages, hence it is simpler for the testers to test the security of the mobile applications. This type of testing is possible by sending any request or file through a malicious message and test whether a mobile application is vulnerable to the malicious message or not.

Key Features:

• It is very easy to install.
• ZAP is available in 20 different languages.
• It is an international community-based tool which provides support and includes active development by international volunteers.
• This tool is also a great for manual security testing.

2. QARK-

QARK stands for “Quick Android Review Kit” and it was developed by LinkedIn. The name itself proposes that it is useful for the Android platform to recognize security loopholes in the mobile application source code and APK files. QARK is a static code analysis tool. It provides information about android application related security risk and also gives a clear and brief description of issues. QARK generates ADB (Android Debug Bridge) commands which will help to validate the vulnerability that QARK detects.

Key Features:

• It is an open-source tool.
• It gives detailed information about security vulnerabilities.
• QARK will generate a report about potential vulnerability and provide information about what to do so as to fix them.
• It features the issue related with the Android version.
• QARK scans all the components in the mobile application for misconfiguration and security threats.
• It makes a custom application for testing purposes as APK and recognizes the potential issues.

What's new in Ionic 5?

What’s new in Ionic 5?

The introduction of Ionic 5 has occurred in the wake of Apple and Google coming up with new UX standards and design patterns for iOS and Android also. The focus is on advancing mobile experiences that are helpful for higher adoption rates and engagement.

With the recent Ionic 5, developers can access everything that is required to create native experiences on the latest mobile devices.

Design and UX are the crucial part of user engagement, the updated framework is perfect to focus less on how to improve the performance of applications and more on what new features to create for users.

What’s New in Ionic 5?

The changes apply deeply to the open-source framework and will extend to React, Angular, and Vue (beta) integrations. If you haven’t heard, they had turned out Ionic React a few months back. As stated above, the updates include significant design revamps which would help Ionic application developers to align their work to meet the latest UX requirements.

1. iOS Design Update–

This is a major update in Ionic 5. The iOS design update is massive and has been implemented across all supported UI components. It benefits the updates brought about by Apple in the recent iOS 13 and its design components. Some design changes in Ionic include the following:

2. Segment-

Ionic 5 has changed the manner in which checked and unchecked buttons are separated in iOS. The segment design now no longer has borders and filled backgrounds.

Rather, a single indicator differentiates between the two buttons. This update accompanies a gesture using which the indicator can simply be dragged.

3. Header–

In response to iOS’s introduction of collapsible headers, Ionic 5 brings support for the same. Specific components have been enabled which can be added to the components responsible for headers. The thought is to help in collapsing the headers without glitches.

4. Titles–

iOS 13 introduced the concept of title of varied sizes after looking over the content. To support the transitions, Ionic 5 has come up with components that enable the shrinking of large titles to a standard size.

Important Rules For Writing Idiomatic TypeScript

Important Rules For Writing Idiomatic TypeScript

Whether you believe or not, but the fact is TypeScript is spreading like wildfire. According to a survey, it was listed as the third most- loved programming language and the fourth most wanted. 

It’s so inevitable since it has replaced vanilla JavaScript as the language of choice for many packages in the JS ecosystem, with some like Yarn even, going similarly as rewriting their entire codebase in TypeScript. We feel one reason for this gigantic rise to be the fact that TypeScript fundamentally is simply JavaScript. This makes the entry bar a lot lower for existing JavaScript developers, and the way that it’s typed may also attract other devs who prefer the features typed languages provide.

This cuts the two different ways, as well, because the simplicity of choosing TypeScript has led to some cases where the language is not being used as effectively as it could be. Numerous developers still write TypeScript like they’re writing JavaScript, and this brings with it some disadvantages. We’ll be taking a look at some real world code written in TypeScript that could be improved to use the language’s strengths.

Rules-

1. Don’t neglect interfaces-

In TypeScript, an interface basically specifies the expected shape of a variable. It’s as simple as that. Let us see the simple interface to drive the exact idea.

interface FunctionProps {
  foo: string;
  bar: number;
}

Now if any variable is defined to implement FunctionProps, it will have to be an object with the keys foo and bar. Some other key addition will make TypeScript fail to compile. Let us see this.

const fProps: FunctionProps = {
  foo: 'hello',
  bar: 42,
}

Now we have an object fProps that implements the  FunctionProps interface correctly. If I deviate from the shape specified in the interface by, say, writing fProps.foo = 100 or deleting fProps.bar, TypeScript will complain. fProps’ shape needs to match FunctionProps exactly or there will be hell to pay.

fProps.foo = true ❌ // foo must be a string

Since we’ve gotten that out of the way, let’s look at an example. Take this React functional component method:

const renderInputBox = (props, attribute, index) => {
  return (
    <div key={index} className="form-group">
      {renderLabel(attribute)}
      <InputBox
        name={attribute.key}
        value={!!isAssetPropAvailable(props, attribute) && props.inputValue}
        onChange={props.handleInputChange}
        placeholder={`Enter ${attribute.label}`}
      />
    </div>
  );
};

While this is totally fine if you were writing JavaScript, it doesn’t take advantage of interfaces. For what reason is this awful? You don’t get any IntelliSense features that you otherwise would if the method’s argument were typed.

Also, you could easily pass in a prop of an alternate expected that shape to this method and you would be none the wiser because TypeScript would not complain about it. This is simply vanilla JS, and you might as well eliminate TypeScript from the project altogether if everything was written this way. How might we improve this? Take a look at the arguments  themselves, how they’re being used, and what shape is expected from them.

We should begin with props. Look at line 7 and you can see that it’s supposed to be an object with a key called inputValue. At line 8, we see another key being accessed from it called handleInputChange, which, from the context, has to an event handler for inputs. We now recognize what shape props should have, and we can create an interface for it.

interface PropsShape {
  inputValue: string;
  handleInputChange: (event: React.FormEvent): void;
}

Proceeding onward to attribute, we can use the same method to create an interface for it. Take a look at line 6. We’re accessing a key called key from it (clue: it’s an object). On line 9, we’re accessing another key from it called label, and with this information, we can create an interface for it.

interface AttributeShape {
  key: string;
  label: string;
}

We can now rewrite the method to look like this instead:

const renderInputBox = (props:PropsShape, attribute:AttributeShape, index:number) => {
  return (
    <div key={index} className="form-group">
      {renderLabel(attribute)}
      <InputBox
        name={attribute.key}
        value={!!isAssetPropAvailable(props, attribute) && props.inputValue}
        onChange={props.handleInputChange}
        placeholder={`Enter ${attribute.label}`}
      />
    </div>
  );
};

consider the benefits of doing this:

• You get IntelliSense wherever you use this method. And you can immediately see what its arguments should look like without having a look at it.
• You can never abuse this method because TypeScript won’t allow you to pass in arguments with wrong shapes.
