AngularJS vs Flask: What are the differences?

AngularJS: Superheroic JavaScript MVW Framework. AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding; Flask: a microframework for Python based on Werkzeug, Jinja 2 and good intentions. Flask is intended for getting started very quickly and was developed with best intentions in mind.

AngularJS belongs to "Javascript MVC Frameworks" category of the tech stack, while Flask can be primarily classified under "Microframeworks (Backend)".

"Quick to develop", "Great mvc" and "Powerful" are the key factors why developers consider AngularJS; whereas "Lightweight", "Python" and "Minimal" are the primary reasons why Flask is favored.

AngularJS and Flask are both open source tools. It seems that AngularJS with 59.6K GitHub stars and 28.9K forks on GitHub has more adoption than Flask with 44.8K GitHub stars and 12.6K GitHub forks.

Lyft, MIT, and Vine Labs are some of the popular companies that use AngularJS, whereas Flask is used by reddit, Lyft, and MIT. AngularJS has a broader approval, being mentioned in 2793 company stacks & 1806 developers stacks; compared to Flask, which is listed in 502 company stacks and 509 developer stacks.

My journey to developing REST APIs started with Flask Restful, and I've found it to be enough for the needs of my project back then. Now that I've started investing more time on personal projects, I've yet to decide if I should move to use Django for writing REST APIs. I often see job posts looking for Python+Django developers, but it's usually for full-stack developers. I'm primarily interested in Data Engineering, so most of my web projects are back end.

Should I continue with what I know (Flask) or move on to Django?

If you want to be a Web developer with knowledge in another frontend and NoSql technology, maybe continue with Flask. However, if you want to create very fast solutions to grow up with a new business and merge these with data analysis and other tools, Django is the answer. Basically read more about the service architecture where you feel more comfortable, Microservice or Monolithic, but please will not married with any because they solve issues to different contexts.

What is the best MVC stack to build mobile-friendly, light-weight, and fast single-page application with Spring Boot as back-end (Java)? Is Bootstrap still required to front-end layer these days?

The idea is to host on-premise initially with the potential to move to the cloud. Which combo would have minimal developer ramp-up time and low long-term maintenance costs (BAU support)?

React might be a good option if you're considering a mobile app for the future, because of react native. Although, Vue.js has the easiest learning curve and offers a better developer ramp-up time. Vue.js is great to build SPAs, very clean and organized and you won't have a lot of long-term maintenance problems (like AngularJS, for example). Bootstrap can still be used, but with flexbox there's no need anymore.

I recommend React because of less memory occupant compare to Angular, but this will depend on your organisation flexibility. When you use React you need to import different libraries as per your need. On the other side angular is a complete framework.

Performance-wise I vote for react js as it loads up quickly and lighter on the mobile. You can make good PWA with SSR as well.

If you are new to all three react will be a good choice considering, react-native will be useful if you want to build cross platform mobile application today or tomorrow. If you are talking about bootstrap styling framework than it's a choice you can style ur components by ur self or use bootstrap 4.0 framework. The complete stack mentioned above is platform agnostic u can run it anywhere you want be it cloud or on-premise.

Which is the best Python framework for microservices?

We are using Nameko for building microservices in Python. The things we really like are dependency injection and the ease with which one can expose endpoints via RPC over RabbitMQ. We are planning to try a tool that helps us write polyglot microservices and nameko is not super compatible with it. Also, we are a bit worried about the not so good community support from nameko and looking for a python alternate to write microservices.

Bottle is much less bloated and fast. Its built-in templating system is one of the fastest as it compiles the templates in bytecode. Also Bottle has no depenencies, preventing dependency bloat.

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.

For starters flask provides a beautiful and easy way to create REST APIs. Also its supported by excellent beginner docs as well as a very active community. Another good thing with Flask is its widely available list of plugins which allow you to build as you go. Its also good in performance and can scale to a quite decent level. However, if you are sure your project is going to be fairly big, it would be better to start with Django as it provides a lot of features out of the box and is extremely stable in performance. Both these frameworks have support for Swagger, JWT, Coverage Report although you have to install plugins for them. Deploying both of these are fairly simple and there is huge documentation available. Django has one of the best documentations I have come across. I hope I was able to answer your queries.

I honestly think the best choice for which framework you use should come down to your team's skills. If you have one Senior Dev that is great at React, but like 3-4 mid-level devs, and a handful of junior devs that know Vue.js ... maybe look at using Vue.js a little more seriously.

Yes, there are pros and cons to framework decisions, but I honestly see a LOT of teams not even consider whether a specific framework is a good fit.

It was easier to find people who've worked on React than Vue. Angular did not have this problem, but seemed way too bloated compared to React. Angular also brings in restrictions working within their MVC framework. React on the other hand only handles the view/rendering part and rest of the control is left to the developers. React has a very active community, support and has lots of ready-to-use plugins/libraries available.

It is a very versatile library that provides great development speed. Although, with a bad organization, maintaining projects can be a disaster. With a good architecture, this does not happen.

Angular is obviously powerful and robust. I do not rule it out for any future application, in fact with the arrival of micro frontends and cross-functional teams I think it could be useful. However, if I have to build a stack from scratch again, I'm left with react.

I used React not just because it is more popular than Angular. But the declarative and composition it gives out of the box is fascinating and React.js is just a very small UI library and you can build anything on top of it.

Composing components is the strongest asset of React for me as it can breakdown your application into smaller pieces which makes it easy to reuse and scale.

I was first sceptical about using Angular over AngularJS. That's because AngularJS was so easy to integrate in existing websites. But building apps from scratch with Angular is so much easier. Of course, you have to build and boilerplate them first, but after that - you save a ton of time. Also it's very cozy to write code in TypeScript.

Our whole Vue.js frontend stack (incl. SSR) consists of the following tools:

  • Nuxt.js consisting of Vue CLI, Vue Router, vuex, Webpack and Sass (Bundler for HTML5, CSS 3), Babel (Transpiler for JavaScript),
  • Vue Styleguidist as our style guide and pool of developed Vue.js components
  • Vuetify as Material Component Framework (for fast app development)
  • TypeScript as programming language
  • Apollo / GraphQL (incl. GraphiQL) for data access layer (https://apollo.vuejs.org/)
  • ESLint, TSLint and Prettier for coding style and code analyzes
  • Jest as testing framework
  • Google Fonts and Font Awesome for typography and icon toolkit
  • NativeScript-Vue for mobile development

The main reason we have chosen Vue.js over React and AngularJS is related to the following artifacts:

  • Empowered HTML. Vue.js has many similar approaches with Angular. This helps to optimize HTML blocks handling with the use of different components.
  • Detailed documentation. Vue.js has very good documentation which can fasten learning curve for developers.
  • Adaptability. It provides a rapid switching period from other frameworks. It has similarities with Angular and React in terms of design and architecture.
  • Awesome integration. Vue.js can be used for both building single-page applications and more difficult web interfaces of apps. Smaller interactive parts can be easily integrated into the existing infrastructure with no negative effect on the entire system.
  • Large scaling. Vue.js can help to develop pretty large reusable templates.
  • Tiny size. Vue.js weights around 20KB keeping its speed and flexibility. It allows reaching much better performance in comparison to other frameworks.

It is a complete waste of time and life to learn a different framework to solve the same problem (Both AngularJS and Angular build A+ UI's, but both require a lot of time to learn). It's dumb to spend 200 hours learning AngularJS, then 200 hours learning Angular when you could spend 200 hours learning AngularJS and 200 hours learning how to solve a different problem (like AI/ML, Data Science, AR/VR, Digital Marketing, etc.)

React has by far and away been our most important library choice throughout the history of Sellpy. It is a library that offers great flexibility supported by a really strong core. The React team is doing incredible work bringing quality features to the core project and tons of quality third party libraries fill in the gaps.

What are some alternatives to AngularJS and Flask?
JavaScript
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
Angular
It is a TypeScript-based open-source web application framework. It is a development platform for building mobile and desktop web applications.
React
Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
Node.js
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
jQuery
jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.
