Usage

Basic example

Use a middleware inside a server:

import { createServer } from 'node:http'
import { json } from 'milliparsec'

const server = createServer(async (req: ReqWithBody, res) => {
  await json()(req, res, (err) => void err && console.log(err))

  res.setHeader('Content-Type', 'application/json')

  res.end(JSON.stringify(req.body))
})

Web frameworks integration

tinyhttp

import { App } from '@tinyhttp/app'
import { urlencoded } from 'milliparsec'

new App()
  .use(urlencoded())
  .post('/', (req, res) => void res.send(req.body))
  .listen(3000, () => console.log(`Started on http://localhost:3000`))

API

raw(req, res, cb)

Minimal body parsing without any formatting.

text(req, res, cb)

Converts request body to string.

urlencoded(req, res, cb)

Parses request body using new URLSearchParams.

json(req, res, cb)

Parses request body using JSON.parse.

multipart(req, res, cb)

Parses request body using multipart/form-data content type and boundary. Supports files as well.

// curl -F "textfield=textfield" -F "someother=textfield with text" localhost:3000
await multipart()(req, res, (err) => void err && console.log(err))
res.end(req.body) // { textfield: "textfield", someother: "textfield with text" }

custom(fn)(req, res, cb)

Custom function for parsec.

// curl -d "this text must be uppercased" localhost:3000
await custom(
  req,
  (d) => d.toUpperCase(),
  (err) => {}
)
res.end(req.body) // "THIS TEXT MUST BE UPPERCASED"

What is "parsec"?
