Stream RAR Archives

A module to stream the contents of RAR archives through a HTTP server.

This module is based on rar-stream by @1313, it currently supports only unpacking and cannot be used for decompression.

Run the Server

npm install
npm start

HTTP server routes are explained in the Router docs

Programatic Usage

Router

const rarHttp = require('rar-http')
const express = require('express')

const app = express()

app.use(rarHttp.router())

const port = process.env.PORT || 7879

app.listen(port, () => {
  console.log(`http://127.0.0.1:${port}/stream`)
})

This adds the following routes:

• /create - POST - expects an array of URLs to RAR files, replies with {"key":"fiql"}
• /stream - GET - expects a key= (key from /create), it also supports o= for a JSON stringified list of Options

Streams

const fs = require('fs')
const rarHttp = require('rar-http')

async function getRarStream() {
	const key = rarHttp.create([
		'http://test.com/file.r00',
		'http://test.com/file.r01',
		'http://test.com/file.r02',
	])

	const file = await rarHttp.file(key, {
		fileMustInclude: ['Lorem Ipsum'],
		maxFiles: 1
	})

	file.createReadStream({
		start: 0,
		end: file.length - 1
	}).pipe(
		fs.createWriteStream(`./${file.name}`)
	)
}

getRarStream()

• rarHttp.create() requires an array of strings with HTTP(s) URLs to RAR files, it return a key which is meant to be used with the .file() method

• rarHttp.file(key, opts) supports the same Options as the /stream endpoint, key is required, but opts is optional, this method returns a promise that resolves to an InnerFile

Options

Options:

{
	"fileIdx": 1,
	"fileMustInclude": ["/dexter/i", "the hulk"]
}

• fileIdx - integer - selects the file that matches the index in the RAR archive
• fileMustInclude - array of strings (can also be RegExp string) - selects the first file that includes any of the matches

InnerFile
