Key Steps To Convert E-Commerce Store Into M-Commerce App

 

Number of mobile users has substantially increased in the past a few years. So businesses came to know the importance of having their own mobile app for more reach and more sales. And so mobile apps entered into the business industry and ecommerce industry is not an exception. An ever increasing number of smartphone users across the globe has given rise to m-commerce or m-commerce apps. Also people have changed the shopping behavior and it is in favor of mobile devices that contributes to the growth of m-commerce. According to the survey, the global m-commerce market will grow at CAGR of 27% during 2019 to 2024.

Mobile commerce apps are so secure and handy that people trust them to use every day. Developing an app from scratch is costly for small scale business and startups online marketplaces. So they can go with the alternate approach which is to develop a mobile commerce app to use on their existing ecommerce websites. It reduces the cost of app development and also ecommerce apps derived from functional websites take less time to market. Before digging into how to convert an ecommerce store to an m-commerce app, let us see the main difference between ecommerce and m-commerce.

Difference Between Ecommerce And M-commerce-

1. Mobility-

Ecommerce is good for shopping by using desktop devices and laptops. But you can’t carry such devices everywhere. M-commerce meant for mobile devices and it allows users to perform transactions at any time and anywhere. They can use pre-installed payment apps for smooth and fast transactions.

2. Security-

Security is a major worry for users who pay over the internet. These days smartphones can enable two-factor authentication, fingerprint and facial recognition to lock apps and secure your personal things. M-commerce provides dynamic functionalities to the users, better shopping experience, helps to boost sales by innovative, interactive and more personalized marketing strategies which can’t be possible in case of web applications.

3. Location Tracking-

Not every desktop devices can track precise locations. M-commerce applications use GPS for tracking live locations and provide personalized recommendations to users.

Converting E-commerce Website Into An M-commerce App-

M-commerce apps

1. Platform Identification-

There are a lot of ecommerce platforms available to build websites available in the market from feature rich enterprise-grade content management systems like magento to WordPress plugin such as WooCommerce. When you decide to develop an app out of a website with such platforms then identifying the platform is important. The results of this identification decide the fate of course of the app development that’ll follow. For instance, the process is not simple for opencart but somehow tedious for magento.

2. Maintain Consistency Of Look And Feel-

Consistency in UI of the entire app helps customers or app users to get familiar when they switch from website to app. So it is important to consider while converting your existing website into an app. You must ensure that look and feel of the mobile commerce app is the same as that of existing ecommerce website. Website and app both represents your business and a major contribution to building a brand. So it is important that both have similar appearance and performance. The colors, theme and key features should be familiar with consistent performance in mobile commerce application.

3. Define The Features-

There is major difference between the working of website and mobile app. Before converting your existing website to m-commerce app, it is good to define the features and functionality of the app. Define the important features such as a simple registration process with email address or social media accounts, push notifications, order tracking, payment gateways and customer support.

• Verification- Users should verify themselves with email address or phone number while ordering something on the app.
• Push notifications- Apps should notify users regarding offers, discounts to encourage them for purchasing.
• Payment methods- There should be support for multiple payment methods such as net banking, credit/debit card, PayPal and cash on delivery.
• Categories- All items must be arranged properly in various categories so that users can search them without any hassle.
• Tracking- There should be tracking of items and check the status of user’s order.
• Support- You should be able to provide customer support for your products via chat, emails or phone.

4. Development Of API And API Integration-

A cms is a structure of software components that eases the website development process. Magento is one of them which makes ecommerce web development easy and profound. All the software components like web server, database, platform and frontend are part of same system so they can exchange data seamlessly. All these components are handled by the same party so there is no security risk. That isn’t the situation with mobile applications. They don’t form closed system with database. For applications, data exchange is carried out via a bridge called API. So developing app with same database of ecommerce website, API developers have to develop various APIs. Creating REST APIs is a complicated process.

A close integration of APIs and app view is important for app to work seamlessly. View includes more information about the product. There is static data that sticks to the page and then dynamic data got by API from the server. For example, product costs are subject to change and should be pulled from the server by the application prior to showing it to the customer.

5. Testing Of App-

Testing is one of the most important phases for websites and apps also. Mobile app is tested for its multiple features and parameters. Those features should work flawlessly and quality analysis team ensures the app is consistent with the client’s or a standard quality parameters. There are a lot of manual testing where an expert tester uses the application as any user would and reports any bug, whenever found.

6. App Launching-

It is the last step to launch an app on app stores. Apple app store and Google play store are the best medium to launch the app and reach the audience. Users can download app from app stores. You can also distribute app via third-party app stores. Also you need to promote your m-commerce app to boost initial downloads. You can promote through existing websites, PRs, and online too.

10 Secret Costs In Mobile App Development

 

These days, mobile apps are an integral part of our lives. We can get anything with just a few clicks of a mobile app. App industry doesn’t stop here. Mobile apps are now entered in the business world. A recent survey found that many companies are planning to build a mobile app and if so, enterprise mobile app development will outpace desktop application development. But, there are some surprises along the way. As more and more companies enter into mobile application development for the first time, many commit a crucial mistake- they go into the process with a limited knowledge of the true expenses of building up a mobile application.

Most of them believe that development cost starts and ends with the developer. But it is not true. The fact is something different from this. When building a feature rich custom mobile app to achieve your business goals- there is no such thing like cheap, app builder tools or get the app in just 2-3 days. If you’re thinking of investing in mobile app development, you must know details about it’s expenses. Having a good knowledge of required costs would be a best way to avoid financial issues later on. But before we see the details of these unexpected cost, let us differentiate between mobile app types.

Types Of Mobile Applications-

There are three types of mobile applications-

• Mobile web app- These kinds of apps are generally referred to as an “HTML5 app”. These are cross-platform apps that are accessed through a device’s web browser. 
• Native app- Native apps are those apps that are installed on the device itself and distributed via platform’s app store/market.
• Hybrid app- These kinds of apps are the combinations of two apps- Native app and mobile web app. They look and feel like a native app, but are web apps in native wrapper.

Let’s get started with secret costs  in mobile app development.

Types Of Secret Costs In Mobile App Development-

1. Functional Cost-

Functional cost is the cost of implementing an app’s functionality. To work a specific functionality, you need to subscribe to a service that provides a delivery mechanism. There can be a “n” number of services used by applications. As for the cost of these services, it might be hundreds or even thousands of dollars for every month. Push notifications, email, social media integrations, and also sms notification are some examples of paid services.

2. Administrative Cost-

Administrative services provide you continuous access to data so that you can update application’s content and manage users without need of the IT department. It is difficult to predict the cost of administrative services because it depends on the type of mobile app that you are developing. These costs increases, and you’ll need to pay them on an ongoing basis to keep apps alive on a platform. Dashboard emulators, functional services management, dynamic updates, access controls, data segmentation, analytics/event collectors are some of the examples of paid administrative services

3. IT Support Cost-

IT support services/Continuous technical support is important for maintenance of any kind of application. And you can’t make a high quality app without this. Just an issue is that support costs increase with time. API maintenance, bug fixing, app update submissions, ios and android updates, are examples of IT support services.

4. Infrastructure Cost-

Infrastructure costs incorporate costs for data delivery, application hosting and data storage. These services need redundancies and load balancers for security servers and backup. Data storage, image data, servers, content delivery networks, development tools, libraries and support are some of the examples of infrastructure cost.

10 Secret Costs In Mobile App Development-

1. Cost Of Application Design-

Before going in detail of app development, you should decide the level of UI/UX that you’d like to have- Bare(simple with just main functionality), stock(app like most of the apps on store), custom(good design with unique icons, buttons, backgrounds, gestures). Most of the companies assume that app developer will handle the design as well. But it is a big mistake. A good designer is necessary for a mobile app’s success. Why? 

A confusing interface and poorly designed app are the main reasons of uninstalling the app by users. So must invest  in a good designer. If you want to test the app idea, develop an MVP first, see the results and then go further.

2. Publishing App To App Store-

Most of the companies don’t realize that publishing/ keeping an app in app store is not free. Microsoft and apple charge $99 per year whereas, google charges a one time $25 fee. Remember that before your app get published on app store, it has to go through the approval process. And this may take extra time with some extra app development cost. Why? Because, if your app doesn’t meet the app store requirements and guidelines- it will not be accepted by app store. So you need to do some changes in the app so as to get it approved. Additional changes always implies additional costs. This only applies to native and hybrid apps because mobile web apps are not distributed via app store/market. 

3. Cost Due To Change In Requirement-

At the initial stage, cost estimation is given on the basis of initial specifications. But sometimes, there is possibility of change in specifications because business users want extra features or others want to change the design. And each change increases the cost. Underestimating what developer or a development company will end up costing can be a biggest mistake. Generally, they came with a reasonable estimate, but many projects take much longer because of various changes/updates that need to be done. This cost varies by the type and amount of changes in mid of the project.

Most Common Mistakes That Developers Should Avoid

 

Today, we all know the importance of a website or web app for a business. Web application development has evolved from serving static HTML pages to totally dynamic, complex business applications. There are lot of development platforms available to transform simple static HTML pages into interactive applications. Whereas, development environments catch and fix mistakes that early developers battled with usually. On the way of becoming a skilled developer, several mistakes can be made. Whether you’re a beginner or an experienced web developer, you must know some common mistakes that most of the developers make. It just takes one silly mistake to collapse your code. It not only affects the functioning of code but also causes a big loss to enterprise for which a project is built. So you must be aware of the common mistakes in web development. Here we’ve curated some common mistakes, let us have a look.

Most Common Mistakes That Developers Should Avoid-

1. Depending On Website Builders Tool-

These days, most of the companies offer tools to ease the website development with simple drag and drop features. But, it causes an issue in the backend.  With each design decision there is multiple lines of code which slowers the website with time, and this causes performance issues and impact critical functionalities. If you have less time for coding, you can purchase templates at less cost, and you’ll get various responsive and cross-browser compatible templates that are ready to serve your purpose. You just need to include content prior to launching the website. Rather than using website builder tools, it is good to use platforms that offers content management services such as WordPress or Joomla. Aside from seamless hosting of a website, it will serve you various themes that match the purpose of your website.

2. Use Of Outdated HTML-

Developers who started coding in the starting days of HTML may have the habit of using lots or spans and ‘&nbps’s that increases code lines and also causes layout issues in updated browsers like Microsoft Edge. So upgrade your knowledge about the latest technologies and use the latest markup elements like font or center that will ease your job and cleans the code that compiles to the latest industry standards.

3. Incomplete Input Validation-

It is important to validate user input on the client and server side. We all know the sage advice “do not trust user input” but nevertheless, mistakes coming from validation happen all too often. Common impact of this mistake is SQL Injection that is in OWASP Top 10 years after year. Keep in mind that most of the front-end development frameworks provide out-of-the-box validation rules which are easy to use. Also, major back-end platforms uses simple annotations to ensure that submitted data are adhering to expected rules. Implementing validation might be time consuming but it should be a part of your coding practice.

4. Ignoring Cross-Browser Compatibility-

Those days were gone, when only the internet browser was used to browse the websites. These days, there are lots of browsers available- Firefox, Chrome, Safari are just some of them. These browsers prefer to access sites. So, as a developer, it’s your responsibility to ensure that website looks perfect for all desktop/mobile browsers. In any case, your website don’t work appropriately in your user’s browser, they may lose interest in your website. To avoid all this, make use of cross browser compatibility tools. Also check whether there are any functional issues in any of the browsers and debug those issues in real-time.

5. Bloated Responses-

There is a high chance that your web page can be full of high-quality images that has heavy file size. The Javascript and CSS files are quite huge so the source code can be long and complex too. To avoid this, use minimalistic programming techniques, libraries to simplify the program. Careful refactoring is a way to modify the source code of program while keeping the functionality as it is. Always use compressed images with the help of online tools.

6. Not Ready To Scale Software Product-

In this modern world of rapid development, startup accelerators, and instant global reach of great ideas  is a common goal for most of the organizations. Due to this pressure, sometimes good web development teams often ignores certain issues. Generally, most of the time, scaling is taken for granted. MVP concept is great but keep it too far, and you’ll have big problems. Sadly, Choosing a scalable database and web server and isolating all application layers on scalable servers isn’t sufficient.

There are numerous details you have to consider if you want to avoid rewriting important parts of your application later that turns into a significant  issue. Consider that you choose to store uploaded profile pics of users directly on the web server. This is a good solution- files are quickly accessible to the application, file handling methods are available in each development platform and you can use serve these images as a static content, that implies less load on application.

When your application grows, you need to use more than one web servers behind a load balancer. Despite the fact that you pleasantly scaled your database storage, session state servers, and web servers, your application scalability falls due to profile pictures. So you want to implement file synchronization service to ensure that files are spread across web servers. Basically, to avoid the problem, you just need to use a shared file storage location, database or other remote storage solution. 

7. Using Non-Responsive Design-

These days, ignoring responsive web design will result in a large website displayed in a small screen with small buttons that makes it difficult to click and read content which will lead to a bad user experience. Ensure that you target some devices and resolutions before you start development and writing media queries so that website is displayed appropriately on all devices. Aside from testing in emulators, test your website in real devices too to get the feeling of how an end user experience your website when using a real device.

8. Not Paying Attention To SEO-

Generally, developers depend on marketers or content creators for SEO of website. But for the successful SEO, it must be done through out the development. As a developer, you must ensure that all pages contain appropriate alt tags, keywords, site-maps etc.

9. Processor Or Time Consuming Actions In Request Handlers-

Sending emails based on user action from the user request handler can be a mistake. Minimum request can be carried out easily but what, when you scale your system and get a large number of requests sending sending confirmation emails. You may face challenges like connection timeout or your application response time reduces to the great extent. To avoid this, you must have an external mailing service to send emails or notification.

10. RESTful Anti Patterns-

Almost every web application has implemented some kind of REST services for external use or integrating with external systems. We see broken RESTFUL patterns and services that don’t adhere to expected practices. Two common mistakes made when writing a RESTful APR are-

• Use of wrong HTTP verbs- For instance, using GET for writing data. HTTP GET is designed to be idempotent and safe, means no matter how many times you call GET on the same resource, the response should be same. 
• Not sending correct HTTP status codes- For example, sending error message with response code 200.

 HTTP 200 OK
 {
     message:'there was an error'
 }

You just send HTTP 200 OK when the request has not generated an error. In case of the error, you send 400, 401, 500 or other status code which is appropriate for errors that occurred. 

11. Horizontal Scrolling-

Websites with horizontal scrolling are defying the norms of a standard website and users can miss some important information on your website if you have a horizontal scroll bar. These days, vertical scrolls are used on websites to add all the information on your site. Scrolling a website vertically as well as horizontally at the same time will be inconvenient for your visitors, To avoid this, use only vertical scroll on your website. This is simple to implement and also commonly used. And also users are comfortable to use vertical scroll rather than horizontal scrolling.

Wrap Up-

You must always be careful about the authorization and authentication, scalability plan etc. These are some of the common mistakes that web developers should avoid.

Top 11 Golang Best Practices For 2020

Golang’s adoption is increasing day by day. Recently, Golang has been the true norm to build command line tools. For security cases, Go happens to be doing good in their reports for vulnerabilities, with just one CVE registry since 2002. But, not having vulnerabilities doesn’t imply that the programming language is secure. If we don’t follow best practices, the developed app can cause security issues and sometimes it may fail. So, Here we’ll see some best practices that you must consider while developing software with Golang.

Top 11 Golang Best Practices-

1. Use Of HTML Templates-

Cross-site scripting or XSS is one of the most basic and common vulnerabilities. Generally, this consists of the attacker being able to include malicious code in the app to modify the output. For example, one can send a Javascript code as part of the query string in a url. When the app returns user’s value, Javascript code could be executed. So, as a developer, you must know this and sanitize the user’s input. For encoding what the app will return to the use, Golang has a package template/html. Thus, rather than the browser executing an input like <script>alert(‘You’ve Been Hacked!’);</script>, popping up an alert message; you could encode the info, and the application will treat the input as a typical HTML code printed in the browser. HTML server that returns HTML template looks as below-

package main
import (
	"html/template"
	"net/http"
)
func handler(w http.ResponseWriter, r *http.Request) {
	param1 := r.URL.Query().Get("param1")
	tmpl := template.New("hello")
	tmpl, _ = tmpl.Parse(`{{define "T"}}{{.}}{{end}}`)
	tmpl.ExecuteTemplate(w, "T", param1)
}
func main() {
	http.HandleFunc("/", handler)
	http.ListenAndServe(":8080", nil)
}

You can use third-party libraries while developing web apps with Go. Gorilla web toolkit includes libraries to help developers for encoding authentication cookie values. nosurf, which is an HTTP package that helps with the prevention of cross-site request forgery (CSRF).

2. Validate Input-

Validation of entries from the user is for functionality purpose and it also helps to avoid hackers who send harmful data that could damage the system. Also, you can assist users to use the tool by preventing them from making common and silly mistakes. For example, you can prevent a user from deleting several records at the same time. For the validation of user input, you can use native Go packages like strconv to handle string conversions to other data types. Go has support for regular expression with regexp for complicated validations. Despite the fact that Go’s preference is to use local libraries, there are third-party packages like validator. By using a validator, you can include validations for structs or individual fields more easily. For example, the below code validates that the User struct contains a valid email address:

package main
import (
	"fmt"
 
	"gopkg.in/go-playground/validator.v9"
)
type User struct {
	Email string `json:"email" validate:"required,email"`
	Name  string `json:"name" validate:"required"`
}
func main() {
	v := validator.New()
	a := User{
		Email: "a",
	}
	err := v.Struct(a)
	for _, e := range err.(validator.ValidationErrors) {
		fmt.Println(e)
	}
}

3. Use gofmt-

To automatically fix most of the mechanical style issues, Run gofmt on your code. Gofmt will read the go code and will show the properly aligned output after indentation, vertical alignment and even it can re-format the comments also.

Commands and options-

gofmt filename- It prints the re-formatted code

gofmt -w filename- It will reformat the code and updates the file.

gofmt -r ‘rule’ filename- Apply rewrite rule to source before reformatting.

gofmt /path/to/ package- It will format the whole package

For example-

package main
          import "fmt"
// this is demo to format code
            // with gofmt command
var a int=10;
             var b int=15;
                            var c string= “Welcome to Agira”;
       func print(){
                   fmt.Println("Value for a,b and c is : ");
                        fmt.Println(a);
                                 fmt.Println((b));
                                         fmt.Println(c);
                         }

Passing a Command: $ gofmt demo.go-

package main
import "fmt"
// this is demo to format code
// with gofmt command
var a int = 10
var b int = 15
var c string =  “Welcome to Agira”
func print() {
        fmt.Println("Value for a,b and c is : ")
        fmt.Println(a)
        fmt.Println((b))
        fmt.Println(c)
}

4. Avoid Nesting By Handling Errors First-

Rather than using multiple or nested conditions, we can break the condition if we should confront error while processing and continue further with coding. 

Rather you can do like this:

err := request()
if err != nil {
  // handling error
  return // or continue, etc.
}

Less nesting means less cognitive load on the reader. If the if statement has an initialization statement like:

If x, err :=
f(); err !=nil
{
       //handling
error
return
} else {
   // use x
}

At such a time, this may need to define the short variable declaration in the code:

x, err := f()
if err != nil {
             // handling
error 
       return
}
// use x

5. Protect Yourself From SQL Injections-

While using Go, you must consider some specific things. First one is- ensure that the user that connects to the database has limited permissions. Best practice is to sanitize the user’s input or to escape special characters and use HTMLEscapeString function from the HTML template package.

However, one of the critical part of code you’d need to add is the use of parameterized queries. With Go, you don’t prepare a statement in a connection; you prepare it on DB. Let us see the example, how to use parameterized queries:

customerName := r.URL.Query().Get("name")
db.Exec("UPDATE creditcards SET name=? WHERE customerId=?", customerName, 233, 90)

What will happen if the database engine doesn’t support the use of prepared statements? Or what if it affects the performance of queries? One can make use of the db.Query() function, but ensure that you sanitize the user’s input first. To prevent sqlmap there are third-party libraries such as sqlmap. Some of the times, vulnerabilities slip through, or enter our applications by means of third parties.

Make sure that you protect web applications from critical attacks like SQL injections.

6. Error Strings-

No capitalization of error strings(unless start with proper nouns or acronyms).  For Example:

Rather than thics command fmt.Errorf(“Something went wrong”) you can move with this fmt.Errorf(“something went wrong”)
