Recently, on 24th of June 2020, Angular version 10 has been released with the beta version. This a major release and is mainly focused on the ecosystem and quality tools instead of introducing new features. Angular 10 features new date range picker in the Angular material UI component library and warnings for CommonJS imports.
If we take a glance at previous version updates, Angular 9.0 came in use on February 6, accompanied on March 25 by Angular 9.1. On May 28, 2019, Angular 8.0 was released. Here we will see the new features of Angular 10. Before we dig into the new features, let us see how to update your version to Angular 10?
How To Update To Version 10?
Use the following command to upgrade the version to angular 10.
ng update @angular/cli @angular/core
New Features Of Angular 10-
1. Performance-
App Performance is a significant factor for app success and this is what Angular is Known for. With the new Angular 10, we can observe a great improvement in performance as the Type-Checking performance boost is done to the compiler-cli and computation basepath is shifted to lazy-load which allows it to work when needed in TargetedEntryPointFinder.
In previous versions of Angular, basePaths was computed whenever the finder was instantiated, and the resources get wasted when the TargetedEntryPointhad already been pasted.
2. Typescript 3.9, TSLib 2.9 & TSLint v6-
Apart from past versions which supported typescript 3.6, 3.7 and even 3.8, Angular 10 supports typescript 3.9. Typescript is a language built on JavaScript by adding syntax for type declarations and annotations used by the TypeScript compiler to type-check your code.
This in turn clean readable JavaScript that runs on lots of different runtimes. Typescript helps to save the files with high editing functionality across editors. With TypeScript new version 3.9, the team has worked on performance, polish and stability.
Apart from error checking, this version powers things like completions, quick fixes and accelerating the compiler and editing experience.
Some exciting features of Typescript 3.9-
“>” and “}” are considered as invalid JSX text characters with typescript new version.
Typecript’s latest version provides a quick fix solution to include missing return statements in situations where you might forget to return the value from a function at the end of that function.
With angular version10 Typescript automatically detects the types of imports that are used to keep any type of files style clean. Any downleveling to support ES5 in this version will be done at the end of the build process.
Compilations with ‘Promise.all’ and ‘Promise.race’ functions have been attacked and the 3.7 version has now been fixed.
TSlib, the runtime library for TypeScript consists of helper functions, and now updated to TSlib 2.0. Also there is an update on the TSLint static analysis tool for TypeScript to version 6.
// @ts-expect-error comments before a code line as a prefix, with a goal that the TypeScript will not report the error. Typescript will show ‘Unused ‘@ts-expect-error‘ directive if there isn’t any error.
Angular 10 has deprecated the inclusion of ESM5 or FESM5 bundles that save 119MB of download and install time at the time of running yarn or npm install for Angular packages and libraries.
3. Localization-
It is one of the best feature of Angular 10. The latest version supports merging of multiple translation documents that can only load one file with the old versions. But with the new version, customers can specify a couple of documents in keeping with locale and translations from each of these documents can be merged together by message ID. Means you have to put the documents so as of most essential first with fallback translations later.
You might be using a traditional database for many years and have hands on it. But these days blockchain technology is gaining popularity because of the security it provides. If you are running a startup and confused about choosing the best between blockchain and traditional database, then you are not alone as there is a clear confusion when it comes to comparing these both technologies. For beginners, both might sound similar. But, it is not true when many people consider blockchain as just another database.
In fact, blockchain is more than just a database. Here we will compare blockchain vs database. Before proceeding for comparison, let’s see each one in detail.
What Is Blockchain?
Blockchain is better defined as a distributed ledger technology(DLT). It enables a set of peers to work together to create a unified and decentralized network. It uses consensus algorithm through which peers can communicate and also share information or data. There is no need for a central authority and this makes the whole network trustworthy as compared to other networks.
Also, there is no need for a centralized authority which makes the whole network trustworthy when compared to other networks. The terminologies used are proof of work and time-stamping. The system is secure, transparent and immutable. When one peer send information to another, transaction is generated. After generation of transactions, it needs to be validated using consensus algorithms. Here proof of work is used to validate the work, which ensures that only valid transactions are passed into the blockchain. Blockchain is all about the blocks and are used to store transactions and data which is required to operate blockchain successfully.
What Is Database?
Database is a centralized data structure having the ability to read, write, and run by an administrator. It can store multiple copies of same data and its history. Users having appropriate access can execute read and write actions. Centralization is the main property of databases due to which centralization is easy and fast access. It brings many benefits to the database. Storing and accessing data is easy and rapid. But there are some drawbacks and the significant one is the chance of data getting corrupted.
The admin has all rights. Data structure is used by database to store the information. The stored data can be queried using Structured Query Language (SQL). Data elements are stored in the form of tables. Relational database allow to work with multiple databases simultaneously.
Blockchain uses distributed ledger architecture. It is a peer-to-peer enabled network in which each peer connects with another using secure cryptographic protocols. As there are no centralized node, they take part in a consensus algorithm. The various available algorithms are proof of stake, proof of work, proof of provenance and so on. Proof of work is the popular algorithm required to solve complex mathematical equations to validate transactions over the network.
Database is based on client/server architecture that can work in small scale and large scale environments. The server is a centralized processing unit and the client receives information from it. Client server communication is maintained through a secure connection. As database is based on centralized approach, it doesn’t need a consensus as a blockchain. Administrators can control all the aspects of the database and all activities are carried out according to the given permissions.
2. Authority-
Blockchain works in a decentralized manner and it brings many implementation and process changes. Networks are allowed to work independently, without need of any centralized control. Decentralizations bring a lot of implementation changes to the current systems and processes that are used by industries. It allows networks to independently work and remove the need for centralized control.
Whereas database works on centralized approach. The administrator has all the authority to manage, create, modify, delete and control the records in the database. Without an administrator, the database will not function at all. He is at the top of hierarchy and can perform tasks like performance optimization. Also he can change the performance optimization of system and delegate authority to others according to their roles in system management.
3. Data handling And Immutability-
Both blockchain and database work differently for data storage and handling.
Blockchain supports immutability means the data that is written cannot be erased or replaced. Immutability means no data altering is possible within the network.
Blockchain supports two operations, Read and write-
Write Operations- write operation is used to add data and information to the blockchain network
Read Operation- read operation is used to read or retrieve data from the blockchain network
In a traditional database, data can be stored and retrieved easily. CRUD is used to carry out proper operation of the application where CRUD stands for Create, read, Update and Delete. This means that data can be replaced ad erased with new values. Traditional databases don’t exhibit immutability and thus are more inclined to being controlled by a rogue administrator.
4. Speed And Performance-
When a transaction is carried out in a blockchain, it is similar to a database. But is slower due to signature verification, consensus mechanism and redundancy. Signature verification is carried out using cryptographic algorithms. And this is a complex process, hence requires time to process. The blockchain is decentralized and it relies on the consensus mechanism. It requires more time before a transaction can be processed.
Databases are known for blockchain and can handle millions of data at the same time. As it works on a centralized approach, it doesn’t need to go through a signature verification process that makes it faster. Each transaction is automatically verified by the database and can be executed rapidly using a queue.
5. Cost And Resources-
Blockchain is a new technology as compared to traditional database and is still progressing hence businesses requires proper planning and execution to integrate it.As blockchain requires end-to-end implementation and cannot be easily integrated into an existing system as an add-on. Blockchain might provide a cost-effective solution because peers manage the network. Organizations don’t require extra cost.
Traditional database is less costly when compared to the blockchain. It is easy to set up and scale and can work with most of the existing processes. Hence most of the businesses who want a rapid and cost-effective system opt for traditional databases. Businesses do not need to manage extra cost for network handling and hence it saves cost.
When To Choose Blockchain?
Monetary transactions
Transfer of value
Verification of trusted data (identity, reputation, credibility, integrity, etc.)
Public Key Verification
Decentralized applications (DApps)
Voting systems
When To Choose A Database?
Data that need continuous updating, like monitoring and sensors
Confidential information (non-transparent to the public)
Data that does not require verification
Fast Online transaction processing
Financial data from markets that require fast processing
Standalone applications that store data
Which One To Choose?
Here you’ve seen the comparison of Blockchain vs Database with different parameters. Blockchain has an advantage of verification methods but it slows the verification process. Means you have to avoid blockchain where fast execution is necessary. It is beneficial for trust, transparency and verification.
You can prefer databases where critical business processes need to be supported and scaled at the same time. Databases are a better choice for general purpose applications. It is high in performance and scalability.

Google, on August 5, 2020 has launched a version of Flutter 1.20 Stable. In the previous release, Google introduced substantial performance improvements, improved support for Metal on ios and new material widgets. With the new biggest release, Flutter 1.20 has resolved 5485 issues and merged 3029 pull requests. Flutter 1.20 release had 359 contributors from across the world and among them 270 were from the flutter community. Flutter 1.20 stable release includes performance improvements, some UI enhancements, update to the visual studio code extension, autofill for mobile text fields and so on. Each new release of Flutter brings with it increased usage and momentum. Google boasts that, now there are more than 90,000 apps developed with Google Play, which was 50,000 till April. And most of the growth comes from India, which is now the top region for Flutter developers, Google says.
Let’s have a look at the new features and updates of flutter 1.20.
What’s New in Flutter 1.20? Updates & Features-
Performance Improvements For Flutter And Dart-
Google Flutter 1.20 is improved with a performance fix for tree-shake-icons which are default when building non web apps and reduce the size of your app by removing icons that are not used. Icon font tree shaking is currently restricted to True Type Fonts but can be lifted in the future.
Janky animations can affect the overall app. It appears negatively in the first run due to a shady compilation jank. With new Skia Shading Language Shader warm-up, the shader compilation jank can be reduced by 2 times.
Flutter has improved mouse hit testing’s performance in web-based micro-benchmark by 15 times. As a result, Google has been able to add support for mouse cursors which will display in various commonly used widgets.
Along with all these improvements, Google also enhanced the decoding speed and time of Dart’s UTF-8 Decoder. In UTF-8 decoding benchmarks, the company ahs measured improvements of nearly 200% for english text and 400% for chinese text on low-end ARM devices.
1. Autofill for mobile text fields-
One of the most requested features among developers is text autofill in Flutter apps. With the new Flutter 1.20 release, basic autofill functionality has been added. Now you do not need to ask your users to fill the data again that the OS has already collected. The text autofill feature is also brought for web apps too.
2. Interactive viewer widget-
Another new feature in Flutter 1.20 is interactive viewer. This new widget is designed to build interactive elements in your app like pan, zoom, drag ‘n’ drop and so on. The feature takes boundary margin, minScale, maxScale and any type of child property on which transformation is performed. Put your cursor on the property and you can drag n drop, zoom in out using the cursor.
3. Updated DatePicker, TimePicker, RangeSlider, And Material Slider-
This new release includes many updated widgets to match the latest material guidelines. These include Slider and RangeSlider. DatePicker has been updated to include a new compact design as well as support for date ranges. And TimePicker has a completely new style.
4. New pubspec format for publishing plugins-
The pubspec.yamlhas been removed in Flutter 1.20. So now you’ve to adopt the new pubspec.yaml format to update or publish new plugin. The old format did not support specifying which platforms your plugins support, and has been deprecated since Flutter 1.12. The new pubspec.yaml format is now required for publishing new or updated plugins.
For clients of plugins, the tools understand the old pubspec format and will for the foreseeable future. Existing plugins on pub.dev using the legacy pubspec.yaml format will work as usual with Flutter apps for the foreseeable future.
5. Tooling metadata for all tool builders-
This is an update in Flutter 1.20 for developers creating flutter tooling. They have released a complete catalog of metadata for a 395 widgets. For every single widget there are parents, libraries and descriptions available in the Catalog and one icon metadata for material and cupertino icons. Icon metadata includes color mapping, values of the color and icon names and previews as well.
6. Typesafe platform channels for platform interop-
Because of increasing demand from Pigeon authors, google is experimenting the making communication between flutter and host platforms simpler and more secure for Add-to-App and plugins. To fulfill this need google has created Pigeon, a command line tool which uses Dart syntax to generate type-safe messaging code on top of platform channels without including extra runtime dependencies.
With Pigeon, rather than manually matching method strings on platform channels and serializing arguments, you can call Kotlin/Swift/Objective-C/Java class methods and pass non-primitive data objects by directly calling Dart methods. Pigeon is mature enough that we can use it in video_player plugin.
7. Mouse cursor support-
Mouse cursor for desktop is one of the upvoted features of Flutter 1.20. Now you’ll get better, faster and stronger hit testing using your mouse cursor.
8. Updating import statements on file rename-
For visual studio code has a new feature- updating imports on rename. This new feature automatically updates import statements when files are renamed or removed. Right now, it just works for single files, but the support for multiple files will be announced soon.
9. Auto import change in VSCode-
Another improvement is support for auto import changes in Visual Studio Code. Means when you change the location of file from one folder to another, the import will automatically be changed.
Other important changes/updates-
Flutter 1.20 has lots of other new features and developer tools. These are some of few:
support for automatically updating import statements when files are moved or renamed in Visual Studio Code; and more.
an updated Flutter plugins
a new responsive licenses page available from the AboutDialog
a new pubspec.yaml format requirement for publishing
an updated Network page in Dart DevTools with support for web socket profiling
Final Words-
These are some new features and updates from new release Flutter 1.20. There can be few others too. Google says that Flutter 1.20 is the framework’s biggest release yet and is still working on implementing sound null safety support, new versions of Ads, Maps and WebView plugins, tooling support and so on.

Selecting the best framework for web or mobile app development is a tough task for experts as there are so many contender frameworks available in the market. Django and Laravel are the two popular frameworks in the tech pool. Frameworks like Django provide an administration interface. But for many others, developers need to write the code and use it to interact with different parts of the framework. Selecting the right framework for your project will help you to code faster and easier. Also it greatly impacts the development process and helps you to get your project done within client timelines. Here we will see the comparison of Django vs Laravel which will help you decide which framework to choose based on your priorities.
Django-
It is an open-source framework written in Python programming used for web development. It follows MVT(Model View Template) architecture pattern which is generally used to develop complex web apps. Django framework was developed by the Django software foundation and released in 2005. Well know websites like Mozilla, Instagram, Pinterest, Bitbucket and so on.
One of the strong points of Django is, It is very lightweight and having standalone feature for development and testing purposes. The goal of Django is to ease the complex web app development with less time and effort.
Laravel was developed by Taylor Otwell and licensed by MIT License. Initially, it was released in the year 2011. You must need some basic knowledge of PHP before start development with the laravel framework. It is used to develop a content management system(CMS) applications. The framework can help you to build any kind of website, right from simple CMS to social networking sites, news sites, etc. It provides inbuilt features that eases the development with reduced time.
Django Vs Laravel-
We have already acclimatized information of Laravel and Django and how developers can use it according to the project requirements. It is better to compare both the frameworks before you choose one of them for development. Let us see the detailed comparison of Django vs Laravel in terms of different parameters.
1. Type-
Django-
Django is an open-source framework preferred by most of the developers. This framework is equipped with libraries, templates and an API for connectivity and natural upgrades. In terms of coding, it follows the D.R.Y principle.
Laravel-
It is also a free and open source web app framework with an easy flowing elegant syntax. It makes the web development process easy and rapid. This framework eases the pain points by making common tasks like routing, sessions, caching and authentication. Laravel is more suitable to develop large , powerful apps. Expressive migration system, inversion of control container and tightly integrated unit testing support are the best features of laravel framework.
2. Programming language-
Django-
Django is a full-stack web application framework that is coded and written in Python. It follows the MVT architecture dissimilar to Laravel. The TIOBE programming community indexed Django in the 4th place and 2nd position in terms of popularity.
Laravel-
Laravel is a full-stack web application framework that is coded and written in PHP. It follows an OOP or object oriented programming approach and Model-view-controller approach. The TIOBE programming community has ranked PHP in the 7th position and 5th position in terms of popularity on GitHub.
3. Learning Curve-
Django- Learning curve for python is almost non-existent and this makes Django simple and easy to deploy.
Laravel-
Laravel is more natural and has a steeper learning curve. This framework let you master modern PHP development with database migrations, Eloquent ORM Composer, packages, REST, templating, etc.
4. Security-
Django-
User authentication system of Django provides safe way to manage user accounts that allows developers to abstain from making common mistakes like clickjacking, forgery etc.
Laravel-
It uses salted and hashed passwords means passwords will never be saved as regular text. It also uses “Bcrypt Hashing Algorithm” for encrypted versions of passwords. Laravel also has some mechanisms to protect their users in events like cross-site scripting (XSS) attacks, SQL injection vulnerability, intercepting private information, insecure cookies and so on.
5. Library-
Django-
It includes a wide range of libraries and self-contained packages that provide reusable features.
Laravel-
It possesses a good set of libraries to build any website. It has detailed documentation and a video tutorial library of over 1100 video tutorials.
6. Scalability-
Django-
Django is highly scalable, as it is a python based framework.
Laravel-
Laravel is also scalable but when compared to Django, it has some limitations to support high scalability. But with new versions, web apps having high traffic can employ laravel development.
7. Template-
Django-
It has a Jinja template that allows customizations of globals, filters, tags and tests. It allows designers to call functions with different arguments on objects.
Laravel-
Laravel development is carried out on Blade template which is a powered and fully featured template.
8. Speed-
Django-
Since python is a high performance language the execution is pretty fast. Hence Django is faster and it allows developers to speed up web applications. Results of Django for Plaintext test – 3127 requests/seconds, JSON test – 3060 requests/ seconds, Random SQLite Fetch test – 2137 requests/ seconds.
Laravel-
Laravel has numerous in-built features. But with these extra features, it makes laravel slower than other PHP based networks. With the version 7, the performance and speed has been improved to compete with others. Results of Plaintext test – 212 requests/seconds, JSON test – 167 requests/ seconds, Random SQLite Fetch test – 140 requests/ seconds.
The final selection of framework is dependent on project requirement. The main aim of Django is to allow developers to rapidly develop projects and it fulfills that. It also removes security issues like cross-site request forgery, SQL injection, cross-site scripting and clickjacking.
On the other hand, laravel offers an easy approach for routing. One can easily build huge enterprise grade apps or simple JSON APIs with laravel and test through unit testing.
If you are still confused about choosing the best one between Django and laravel, consult with solace experts. We have dedicated developers to help you through consultation and development. You can hire laravel developers and Django developers of Solace team. Connect with Solace and get a free quote for web app development. We will be happy to help you.
Hashgraph Vs Blockchain- Top 7 Differences That You Must Know
You know that blockchain technology is continuously evolving at a rapid pace. Blockchains impact is powerful and is impacting business, finance, education, governance, healthcare even in sports, music. There are other similar distributed ledger technologies(DLT) to replace blockchain technology by providing a better solution. Hashgraph is one of them. It solves the distributed ledger differently and claims to be safer, fast, and fair. So here, we will compare two technologies, Hashgraph and Blockchain and which one is better. Before we proceed to the comparison, let us see each one in detail.
What Is Hashgraph?
Hashgraph is a form of distributed consensus which offers another approach to distributed ledger technology. It is a peer-to-peer platform that expels the requirement for any intermediary to complete transactions. It offers a secure, fair and fast network, and its is implemented using Java and Lisp programming languages. This means it supports solidity. One of the best advantages of Hashgraph is its speed. It can handle thousands of transactions per second and is able to verify more than one million signatures per second.
What Is Blockchain?
Blockchain is a popular form of distributed ledger technology. This technology is used by every cryptocurrency ie., bitcoin. Here, peers communicate between themselves to form a peer-to-peer network. Bitcoin uses the basic form of blockchain technology but is not so efficient. Hence we have seen an ascent in another type of blockchain technology. Ethereum is successful with a huge active community. It is a second generation blockchain which means it supports dApps and smart contracts.
In technical terms, blockchain is a series of blocks or records and supports append-only structure. Despite that, the database is immutable means that data that once written, cannot be deleted or altered by anyone else. Hence blockchain is a perfect solution for the issue where data immutability is necessary. Best use cases of blockchain are, supply chain management, voting and finance industry.
Hashgraph vs Blockchain-
Hashgraph vs Blockchain
1. Programming Language-
Blockchain makes use of languages- Java, C++, Solidity, Ruby and Python. For hashgraph, Lisp and Java languages are used.
2. Approach-
Hashgraph makes use of directed acyclic graph to store and access information. Blockchains are an open-source technology. It stores data in blocks in a linear way. The append approach works seamlessly but it is not always a way for blockchain solutions out there. In both DLTs, each node as a copy of the ledger that makes it decentralized.
3. Consensus Mechanism –
Hashgraph is based on asynchronous Byzantine-Fault Tolerance (aBFT), which provides an improved model of DLT by catering solutions to established cryptocurrency platforms. It uses Gossip about Gossip and virtual voting as a form of gaining network consensus.
Blockchain does not depend on a single approach to consensus. Contingent on cryptography and currency, Blockchain uses numerous consensus algorithms, like Proof of Work, Proof-of-Elapsed Time, Practical Byzantine Fault Tolerance, Proof of Stake, and so on.
4. Speed-
Speed of blockchain varies according to the solution(platform, cryptocurrency, etc.). But it is slower than Hashgraphs. Hashgraph can reach a speed of 5,00,000 transactions per second. Blockchain solutions like ethereum, bitcoin are slow and can do 100 to 10,000 transactions per second. And the Hashgraph Gossip method is a reason behind its speed. With this, less information needs to be propagated across a network.
5. Security-
Blockchain uses a different approach where they use cryptographic methods to ensure security. As we already know, blockchain is a series of blocks or records and that blocks are tamper-proof and no malicious actor can change the integrity of data.
To secure a network from malicious actor, Hashgraph uses an approach- Asynchronous Byzantine Fault Tolerance(aBFT).
Mobile apps have gained importance for businesses due to its innovative features. User-friendly interface and marketing campaigns. If you have ever searched about app development, you might get a lot of stuff about app development frameworks, app development steps, app store optimization tips and so on. After the launch of the App, there is one thing that has its own importance i.e. mobile app maintenance. But there are just a few things that can guide you regarding the maintenance of mobile app. You already know the importance of mobile app development, but do you know the importance of app maintenance?
Here we will discuss all about the need, types and the engagement models of maintenance so that you can plan out your mobile app’s maintenance cost.
Need Of Mobile App Maintenance-
Mobile App Maintenance
1. Hardware-
Nearly every 6 months, new hardware is being launched and adapted by each new phone that is to be launched. Hence your app should be optimized so as to work with modern hardware. This is a time where you need a maintenance team to make changes and release new versions.
2. Operating system-
Each year, there are new updates for iOS and Android version and accordingly apps should be updated for proper functioning.
3. Update app with technological trends-
Let us consider an example of Dark mode which changes the complete theme of your phone to dark in order to lessen the eye strain in case of low lighting. Now consider that, a user is accessing a mobile with dark theme, then he would expect the same from your app too. If you didn’t change the app as needed, the user may face eye strain and hence he may search for another similar app that provides dark mode and uninstall your app.
4. Minimizing uninstalls-
The app journey will not end with the launch of an app. Continuous monitoring and maintenance are the best ways to achieve success and it can be done after the app is being used. It is beneficial and necessary to consider the feedback you receive or the analytics you get. It will help to analyse the behaviour of users and get rid of uninstalls.
5. Integrating emerging technologies-
New technologies are taking over the market and you cannot predict anything about them. The only thing is to integrate it after a stable release. Let us see how maintenance is necessary for your app if it revolves around emerging technologies.
• AI-
Artificial intelligence needs data regularly and hiring a team for maintenance is cheaper than getting panel to control how data is fetched. AI algorithms could be anything but what it will fetch has to go through app directly. In this way, maintenance can solve your problems by changing the code.
• IoT-
IoT allows you to operate devices of daily chores through app, and hence maintenance is necessary
• AR-
Aligning images that are displayed on your phone is an ongoing task and it can be carried out smoothly through maintenance. Augmented reality always need more objects as your customers increases and it is better to hire permanent designers to make them, maintenance team would be cheaper for deploying them and updating the app accordingly.
6. Security-
Applications may be affected by security holes, and you have to update the app so as to fix the issues.
Apart from all these points, you should frequently update your app to keep it top on the app store.
Types of app maintenance-
1. Corrective-
Corrective maintenance includes removing faults and residual errors in the daily app functions. Residual errors are the errors in design, logic and coding.
2. Adaptive-
Adaptive maintenance is the maintenance carried out to achieve perfect adaptability to modern technologies and app store guidelines after the app is deployed. The environment where your app would work in would always be upgrading, so it is necessary to carry out adaptive maintenance.
3. Perfective-
As users use app, some new requirements can be discovered. Perfective maintenance considers these feedback and make functional modifications in the source code to provide users a perfect user experience as they expect.
4. Emergency-
This type of maintenance can take care of all abrupt issues and errors that expect immediate intervention. Whenever an organization detects an unpredictable issue with their app, they must go with emergency maintenance.
App Maintenance Cost-
The app maintenance cost is based on the type of app and complexity. You can distinguish app maintenance cost into following categories-
1. Hosting costs-
According to the number of users, your hosting cost can increase. It may go up to thousands or ten thousands of dollars each month. These expenses do not include human expenses of creating and maintaining the backend but are important as your app scales up.
2. Monitoring and crash analytics-
You will need app analytics tools to monitor usage patterns to improve in-app experience. You must invest in tools that will send you real time crash reports.
3. App store optimization-
App store optimization is important to list your app on app store. You should spend considerable time to keep your app store listing updated by searching appropriate keywords, A/B testing headlines and descriptions, answering reviews, considering feedback, uploading screenshot or videos as features change, running search ads etc.
4. Licenses-
Most of the apps were built using licensed technologies. Some licenses are taken for life, while others need to be renewed on a yearly basis. You must consider the app licensing cost while setting the app maintenance cost.
Apart from these, there are some activities that costs you are as follows-
Product or demo video
Content marketing
Contests and giveaways
Social media marketing
In-app ads
App Store ads
In-app content creation
Facebook ads
Adwords ads
Email
Final Words-
Mobile app maintenance is important to succeed. Many apps have failed down because creators forget that the users want things according to their way and not the perfect way. App maintenance is not a one time task. As the market is competitive, once the app is launched, it needs more attention and maintenance to provide the expected user experience.

Selecting the best technology is an important step for web development as it decides how your website and app will perform. There are a lot of web development frameworks and technologies available in the market and hence many entrepreneurs and freelancers get confused to choose the best from a large pool. Most of the entrepreneurs prefer frameworks that are entirely open-source, have wide community support and offer rapid development. Web app development is divided in two parts: front end development and back end development, accordingly there are a lot of tools available to develop robust and scalable web apps.
Django and Ruby on rails are the two most popular web applications that offer development of interactive and scalable websites and web apps. Before proceeding towards Django vs Ruby on rails, let us see each one in detail.
What Is Django?
Django is a Python based web framework released in 2005. It is an open-source and general purpose framework which makes it popular among web developers. This framework was designed to simplify the development of complex and database driven websites. It allows rapid development with neat and pragmatic design.
What Is Ruby on Rails?
Ruby on Rails is a server-side, open source web app framework written under MIT Licence. Rails provides a great default structure for database, pages and web services. It works on DRY(Don’t Repeat Yourself) and Conversion Over Configuration. DRY eliminates the need of doing the same task of coding repeatedly and Conversion Over Configuration means you can adapt instead of creating your own rules every time. And this makes the whole process easy.
Similarities Between Django And Ruby on Rails-
