Express.js vs FastAPI

Setting up a new Express project is very easy. It consists of installing a handful of libraries through NPM run a single npm install and everything is ready to go.

Express' extremely powerful routing API allows developers to do tasks ranging from building a REST API to building the routes for a simple web app and then take it to the next level by using route parameters and query strings.

With a little learning curve, it is a good choice for new NodeJS developers to get started quickly. Express boasts great, thorough documentation.

Node.js Foundation

Announcement here

The Node.js Foundation is a Collaborative Project at The Linux Foundation. Linux Foundation Collaborative Projects are independently funded software projects that harness the power of collaborative development to fuel innovation across industries and ecosystems.

Being a somewhat old Node.js web app framework and being one of the most widely used frameworks, Express.js has matured quite a lot during all that time. It's more stable than its competitors and a huge community backing it.

Express takes advantage of Node's NPM to distribute and install countless plugins made by third parties which solve almost anything a developer would want to do with Express.

It's by far the most popular framework for node.

Express has a big community with a lot of guides and tutorials written about it by developers that have been using it for quite some time.

You can easily add oAuth integration/social logins to your next web app without much hassle, using this authentication middleware for connect.

Very simple and fast.

If you have not already checked out the Express.js ecosystem of middleware, you should.

It has a simple but powerful dependency injection system, it can be used to handle authentication, per-user rate limiting, authorization controls (e.g. with roles), etc.

It is based on standards: OpenAPI, JSON Schema and OAuth 2.0.

It validates the data using the types you declared. Even in deeply nested JSON requests.

It's based on Starlette and Pydantic, so, it's one of the fastest Python frameworks.

It is based on Python type declarations, so, editors and tools can give great support. Including type checks and autocompletion everywhere.

It's easy to develop API based applications in Python on deadlines for Android and IOS Development.

It generates interactive API documentation automatically from your code.

It's independent of database or ORM, but compatible with all of them. Including relational databases and NoSQL.

It's based on Async IO, which gives it high concurrency. But you can use non-async libraries and it runs them appropriately.

It has some of the best documentation of any framework.

Because it's an async framework, it can handle async-native protocols like WebSockets.

It has integrated support for OAuth 2.0. Including declaring required scopes per endpoint. So, you can easily integrate it with external OAuth 2.0 providers or build your own with it.

Included support for background tasks, thanks to being based on Starlette.

Python's graphene library is included as an optional dependency meaning that GraphQL API's are supported out of the box, with no additional tweaking needed.
