@barelyhuman/tiny-use

The tiniest middleware library for node's HTTP

Invisible if you squint hard enough

@barelyhuman/tiny-use

Why ?

I've written this in my experimentals sink for over 1.5 years now, the first public version of the same is available here barelyhuman/http/middleware.

I made it to be small and contained to reduce the middleware's load on node's server.

With respect to:

Performace - It's linear and basically depends on what load you add in
your actual middleware since it itself has no overhead.
Reason - Like everything else, I've written it more than once and reached
a point of saturation where I don't want to reduce it's size in terms of code
and functionality.
Stability - The API isn't going to change since it's very basic and ties
to the Node API so unless that changes, makes no sense for this to change

Installation

; npm i --save @barelyhuman/tiny-use

Usage

Node HTTP API

To use with the default node:http/http API, you use it just like any other express js middleware, the difference being that the middleware now supports async flow

import http from 'node:http'
import { use } from '@barelyhuman/tiny-use'

http.createServer(
  use(
    async (req, res, next) => {
      req.value = 1
      await next()
      console.log({
        value: req.value,
      })
    },
    async (req, res, next) => {
      req.value = 2
      res.end('Final Message')
      return
    }
  )
)

Ecosystem

You don't have to rebuild an ecosystem, most of what connect has and what express uses should be usable.

Fetch Compliant API

If you work with network functions that are more inclined to the Fetch API standard and you need to use common middleware instead of manually calling them in each function call, you can do so by making minor modifications to the import

import { use } from '@barelyhuman/tiny-use/fetch'

const withMiddleware = use(
  req => {
    req.userId = 1
  },
  req => {
    return new Response(req.userId)
  }
)

export default {
  fetch: withMiddleware,
}
