YAHF

Yet Another HTTP Framework, that you don't really need

Trying to build a HTTP server framework, without using any external modules, because who needs npm?!

Everything is as I want it to be, not as one might used to.

API

• Create new YAHF instance, with default options

  import YAHF from 'yahf';
  
  const server = new YAHF();

• Options that can be passed to the YAHF constructor, as an object:

  • logger: (str: string) => void. Defaults to console.log.
  • port: number. Defaults to 1337.

• useMiddleware(middleware: (data) => void).

  • Any result returned from this functions will be ignored.
  • Will be called in FIFO.
  • Return this so it can be chained.

example:

import YAHF from 'yahf';

const server = new YAHF()
server.useMiddleware((data) => {
    server.logger(data);
})

• addHandler(path:string | string[], handler: async data => RequestResult | undefined.

  • Return this so it can be chained.
  • RequestResult is optional.

• RequestResult

  {
      statusCode: number; // Defaults to 200
      contentType: string; // Defaults to 'application/json'
      payload: any;
  }

• start() : Promise<this>

  • Will start the server, listening on the port was passed in.
  • Resolves to this so it can be chained.

• kill() : Promise<this>

  • Will close the server.
  • Resolves to this so it can be chained.

• logger : (str: string) => void

  • Returns the passed in logger. will default to console.log

Request lifecycle

• Every middleware/handler will get the following object:

  {
    path: string;
    query: URLSearchParams;
    method: 'GET' | 'POST' | 'PUT' | 'DELETE' | 'PATCH'...;
    headers: object;
    payload: string; // Defaults to an empty string
  }

• Middlewares are called FIFO, and called before any handler.
• Handlers are called for exact match for the path, without starting /.
