Bayer.js

Reactive server abstractions library for Node.js.

import Bayer from "@bayerjs/core";
import staticFiles from "@bayerjs/static";
import Router from "@bayerjs/router";

const server = new Bayer();
const router = new Router();

router.route("GET", "/", ({ res }) => {
  res.status(403, "Unauthorized").json({ error: "You are not authorized" });
});

// Use middleware
server.use(staticFiles({ localPath: join(__dirname, "../public") }));
server.use(router.middleware(), 1); // Optional priority (here to set it higher than the static files to override routes);
// Run the server
server.listen(3000).then(() => console.log("Listening on http://localhost:3000"));

What it is

Bayer is a reactive library that abstracts away the difficulty of setting up a Node.js server with common-case features. It uses rxjs handle data-flow, as it is basically the textbook use-case of reactive programming.

Modular

As its smallest, Bayer provides you with an Observable, providing Request and Response parameter objects, which are based on Node.js's IncomingMessage and ServerResponse objects. library.

Bayer can easily be extended through the use of Middlewares, they're OperatorFunctions that get piped to the main request Observable. They can be as simple or as complex, and benefit from all the power of the RxJS Operators.

Easy

While being introduced to Reactive programming will make your life easier, the project aims to make writing feature-complete servers as easy and as quick as possible. If you need a "quickstart template" that's more than 50 lines of code when creating a new project, then this project's purpose has been defeated.

What it isn't

Bayer isn't batteries included; it won't do everything for you. However, the project tries to strike a balance between minimalism and availability of features.

Note that because Bayer has been designed with modularity in mind, functionality can easily be added through the use of middlewares.

Why the name "Bayer"?

Because I was listening to Andrew Bayer's album when initially building the project, and that it's a cool name, and because the JavaScript community needs some beautiful music.

^{But if you ask me, this version is much better 😝}
