Flask vs React Native: What are the differences?

Introduction

Flask and React Native are two popular technologies used for web and mobile app development, respectively. While both serve different purposes, there are key differences between the two.

Server-side vs. Client-side: Flask is a Python-based web framework used for server-side development, where the majority of the processing occurs on the server. On the other hand, React Native is a JavaScript framework used for client-side development, allowing the app to run natively on mobile devices.
Language: Flask uses Python as its primary programming language, making it well-suited for developers familiar with Python. In contrast, React Native utilizes JavaScript, which is a widely used language for web and mobile app development.
User Interface Development: Flask primarily focuses on the backend and server-side logic, leaving the user interface development to other technologies. React Native, however, provides a full-fledged toolset for building user interfaces, allowing developers to create native-like components that can be used across multiple platforms.
Platform Support: Flask, being a server-side framework, can be used to develop web applications that can be accessed through various devices and platforms. React Native, on the other hand, is specifically designed for mobile app development and supports both iOS and Android platforms.
Workflow and Development Process: Flask follows a more traditional web development workflow, where changes in the code require the server to be restarted for the changes to take effect. React Native, on the other hand, offers a hot-reload feature that allows developers to see the changes instantly without the need for restarting the app. This makes the development process faster and more efficient.
Community and Ecosystem: Flask has a mature and extensive community, with a wide range of libraries and extensions available to enhance its functionality. React Native, being a relatively newer technology, also has a growing community, but with a focus on mobile app development. It offers a rich ecosystem of pre-built components and libraries specifically designed for mobile development.

In summary, Flask is a Python-based web framework used for server-side development, while React Native is a JavaScript framework used for client-side mobile app development. Flask focuses on backend logic and supports web platforms, while React Native provides a full-fledged toolset for building cross-platform mobile apps with native-like components. Flask uses Python as its primary language, while React Native uses JavaScript. The development process and community support also vary between the two technologies.

Advice on Flask, React Native

Decided

We built the first version of our app with RN and it turned out a mess in a while. A lot of bugs along with poor performance out of the box for a fairly large app. Many things, that native platform has, cannot be done with existing solutions for RN. For instance, large titles on iOS are not fully implemented in any of existing navigations libraries. Also there's painfully slow JSON bridge and many other small, yet annoying things. On the other hand Flutter became a really powerful and easy-to-use tool. A bit of a learning curve, of course, because of Dart, but it worth learning. Flutter offers TONS of built-in features, no JSON-bridge, AOT compilation for iOS.

Vue.js

Vue Native

React

I'm a huge fan of Vue.js and I'm pretty comfortable with it. I need to build a mobile app for my company and I was now wondering whether I could make use of VueJS with Vue Native instead of switching to React. I know Vue Native builds on top of RN. My question is whether I'd have as much freedom with Vue Native over RN and whether you feel like Vue Native is "production ready" or not. Not sure of which shortcomings I may find using Vue Native... Thanks a lot!!!

Needs advice

I have just started learning Python 3 weeks ago. I want to create a REST API using python. The API will be used to save form data in an Oracle database. The front end is using AngularJS 8 with Angular Material. In python, there are so many frameworks to develop REST APIs.

I am looking for some suggestions which REST framework to choose?

Here are some features I am looking for:

Easy integration and unit testing, like in Angular. We just want to run a command.
Code packaging, like in java maven project we can build and package. I am looking for something which I can push in as an artifact and deploy whole code as a package.
Support for swagger/ OpenAPI
Support for JSON Web Token
Support for test case coverage report

Framework can have features included or can be available by extension. Also, you can suggest a framework other than the ones I have mentioned.

Detailed Comparison

Flask	React Native
Flask is intended for getting started very quickly and was developed with best intentions in mind.	React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.

What are some alternatives to Flask, React Native?

Ionic

Free and open source, Ionic offers a library of mobile and desktop-optimized HTML, CSS and JS components for building highly interactive apps. Use with Angular, React, Vue, or plain JavaScript.

ExpressJS

Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications.

Flutter

Flutter is a mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.

Xamarin

Xamarin’s Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual Studio*), as well as skills in .NET and the C# programming language, to create mobile applications for the industry’s most widely-used mobile devices, including Android-based smartphones and tablets, iPhone, iPad and iPod Touch.

NativeScript

NativeScript enables developers to build native apps for iOS, Android and Windows Universal while sharing the application code across the platforms. When building the application UI, developers use our libraries, which abstract the differences between the native platforms.

Django REST framework

It is a powerful and flexible toolkit that makes it easy to build Web APIs.

Sails.js

Sails is designed to mimic the MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with scalable, service-oriented architecture.

Apache Cordova

Apache Cordova is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.

Sinatra

Sinatra is a DSL for quickly creating web applications in Ruby with minimal effort.

Framework7

It is a free and open source mobile HTML framework to develop hybrid mobile apps or web apps with iOS native look and feel. All you need to make it work is a simple HTML layout and attached framework's CSS and JS files.
