Mach vs Express.js

Mach has some pretty cool streaming functionalities built directly into it, if your web app provides any audio/video/data streaming features, you can consider using Mach to build it.

Since Mach already is asynchronous (stateless) which means your logic is implemented by using promises (then objects); hence your functions are pretty independent and composable.

No complex layers between plain HTTP requests and the corresponding JS functions invoked. Which in turn means each GET/POST/PUT or any other HTTP request is directly mapped to a Javascript function. Hence leading to a huge increase in performance for your app

One of the distinguishing features of Mach is it's robustness, errors won't be terminating your complete app, instead they'll bubble up so you can handle them gracefully.

Like most of the Node.js's core, Mach is an asynchronous web framework too. Each response (of a request) can simply be hooked up to a then method so that its result or the reason for failure can be retrieved after the action is complete. If you're wondering what async operations are, here's a pretty good explanation for you

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.
