http-utils

Helper utilities for Luvit.io servers.

Install

You can install all libraries as one dependency:

lit install voronianski/http-utils

Modules

Or install every library separately:

http-methods

HTTP verbs that Luvit.io aim to support.

lit install voronianski/http-methods

mimes

Mime type getter from string.

lit install voronianski/mimes

local mimes = require('mimes')

p(mimes.getType('foo.jpg'))
-- 'image/jpeg'

match-path

Match an Express.js-style path string such as /user/:name and get params.

lit install voronianski/match-path

local matchPath = require('match-path')

local parse = matchPath.compile('/foo/:bar')
-- parsing function

local params = parse('/foo/1')
-- {foo = '1'}

on-headers-event

Patches HTTP ServerResponse with 'headers' event which executes a listener when a response is about to write headers.

lit install voronianski/on-headers-event

-- patches http.ServerResponse:flushHeaders method
require('on-headers-event')

require('http').createServer(function (req, res)
  res:on('headers', function 
    -- do something with headers before they are sent
  end)
  res:finish()
end):listen(3000)

response-methods

Patches HTTP ServerResponse with useful response shortcut methods.

lit install voronianski/response-methods

-- adds helpful http.ServerResponse methods
require('response-methods')

local Utopia = require('utopia')
local app = Utopia:new()

app:listen(3000)

`res:status(code)`

res:status(403):finish()
res:status(400):send('Bad Request')
res:status(404):sendFile('/absolute/path/to/404.png')

`res:json(table)`

res:json({user = 'tobi'})
res:status(500):json({error = 'message'})

`res:redirect([status], path)`

res:redirect('/foo/bar')
res:redirect('http://example.com')
res:redirect(301, 'http://example.com')
res:redirect('../login')

`res:send([body])`

res:send(Buffer:new('whoop'))
res:send({some = 'json' })
res:send('<p>some html</p>')
res:status(404).send('Sorry, we cannot find that!')
res:status(500).send({error = 'something blew up'})

`res:sendStatus(code)`

res:sendStatus(200) -- equivalent to res:status(200):send('OK')
res:sendStatus(403) -- equivalent to res:status(403):send('Forbidden')
res:sendStatus(404) -- equivalent to res:status(404):send('Not Found')
res:sendStatus(500) -- equivalent to res:status(500):send('Internal Server Error')
