Usage

Basic example

Use a middleware inside a server:

import { createServer } from 'node:http'
import { json } from '@otterhttp/parsec'

const parseJsonBody = json()

const server = createServer(async (req: HasBody, res) => {
  await parseJsonBody(req, res, (err) => void console.log(err))

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

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

Web frameworks integration

otterhttp

import { App } from '@otterhttp/app'
import { urlencoded } from '@otterhttp/parsec'

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.

custom(fn)(req, res, cb)

Custom function for parsec.

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

What does "parsec" mean?
