Express.js vs ASP.NET Core

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.

Thanks to breakthroughs in ROSLYN compiler and the efforts of the .NET COre developer team, code written in C# can reach speeds just a step behind C++.

Can run on Windows, Linux and Mac (also Visual Studio Code editor).

In .NET Core 2.1 and 3.0, new APIs are added that make it possible to write JSON APIs that require less memory, using Span<T> and UTF8 strings, and improve throughput of applications like Kestrel, ASP.NET Core web server. See also Utf8JsonReader.

Both microsoft and 3rd party tutorials are mostly of high quality and encourage you to use the industry best-practices.

Built-in middleware featuring: Authentication, Cookie policy, Health Check, MVC, Session etc.

Ability to host on IIS, Nginx, Apache, Docker, or self-host in your own process.

It is a very secure platform.

Both VS and VSCode are powerful free IDEs that are well integrated with ASP.net Core. VS Community also allows for commercial use for projects with less than 5 developers.
