live_chat VS Express

When I first started this project, I wanted to build a live chat application, one of the fundamental pieces of software in any social product. I made an app using the popular Javascript express (server) and socket.io (websocket) libraries which worked fine in local development. When it came to deploying it online, I didn't want to just deploy it openly (without authentication) as there might be bots crawling the internet, looking for open websocket servers to spam and so on. On the other hand, I didn't want to use my domain for authentication (and registration) services for this pet project. The idea of using serverless JS workers came to me as I was thinking about how to architect the application with the least possible backend exposure. Luckily, several cloud vendors provide such services nowadays so it's only a matter of time to integrate with their interfaces.

On the index.js, environment variables are loaded, then we can find the API routing powered with Express. Here is the /send request:

Express: A lightweight framework for building web applications.

Now, we will create API using expressjs. When we created application using --ssr flag, the Angular CLI already took care of installing expressjs for us.

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Basic Knowledge of Express

Express.js Documentation

In the JavaScript ecosystem, there are guides for enabling SAML-based enterprise single sign-on in AdonisJS, Express.js, Next.js, Remix, and React with an Express.js backend.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.
