Salute

Salute is a high order function you can use as a middleware for your HTTP servers:

• Chunked encoding: The data returned by your function is decomposed into series of chunks using chunked transfer encoding. Salute automatically reduce time to first byte and work around the v8 heap memory limit while having low memory footprint.
• Polymorphic: Salute provides a single interface to process whatever data returned by your function. It even accepts promises of streams.
• HTTP status: Return an HTTP error to automatically send status with custom payload through the response.

Usage

const salute = require('salute')
const http = require('http')
const createError = require('http-errors')


const middleware = salute((req) => {
  switch(req.url) {
    case '/stream':
      return fs.createReadStream('hello.txt')
    case '/errors':
      return createError(401, 'Please login')
    default:
      return 'hello world'
  }
})


http.createServer((req, res) => {
  middleware(req, res).pipe(res)
})

Salute automatically know which type of data you want to send through the response and set the appropriate content type (text/plain for promises and streams). However, you can set the response header with a content type of your choice:

salute(fn, 'csv')

npm install salute --save
