tus-node

Powered by tus-node-server

tus is a new open protocol for resumable uploads built on HTTP. This is the tus protocol 1.0.0 node.js server implementation.

Installation

$ npm install tus-node

Flexible Data Stores

• Local File Storage

  server.datastore = new tus.FileStore({
      path: '/files'
  });

• Google Cloud Storage

  
  server.datastore = new tus.GCSDataStore({
      path: '/files',
      projectId: 'project-id',
      keyFilename: 'path/to/your/keyfile.json',
      bucket: 'bucket-name',
  });

• Amazon S3

  
  server.datastore = new tus.S3Store({
      path: '/files',
      bucket: 'bucket-name',
      accessKeyId: 'access-key-id',
      secretAccessKey: 'secret-access-key',
      region: 'eu-west-1',
      partSize: 8 * 1024 * 1024, // each uploaded part will have ~8MB,
      tmpDirPrefix: 'tus-s3-store',
  });

Quick Start

Use the tus-node-deploy Docker image

$ docker run -p 1080:8080 -d bhstahl/tus-node-deploy

Build a standalone server yourself

const tus = require('tus-node');

const server = new tus.Server();
server.datastore = new tus.FileStore({
    path: '/files'
});

const host = '127.0.0.1';
const port = 1080;
server.listen({ host, port }, () => {
    console.log(`[${new Date().toLocaleTimeString()}] tus server listening at http://${host}:${port}`);
});

Use tus-node as Express Middleware

const tus = require('tus-node');
const server = new tus.Server();
server.datastore = new tus.FileStore({
    path: '/files'
});

const express = require('express');
const app = express();
const uploadApp = express();
uploadApp.all('*', server.handle.bind(server));
app.use('/uploads', uploadApp);

const host = '127.0.0.1';
const port = 1080;
app.listen(port, host);

Use tus-node with Koa or plain Node server

const http = require('http');
const url = require('url');
const Koa = require('koa')
const tus = require('tus-node');
const tusServer = new tus.Server();

const app = new Koa();
const appCallback = app.callback();
const port = 1080;

tusServer.datastore = new tus.FileStore({
    path: '/files',
});

const server = http.createServer((req, res) => {
    const urlPath = url.parse(req.url).pathname;

    // handle any requests with the `/files/*` pattern
    if (/^\/files\/.+/.test(urlPath.toLowerCase())) {
        return tusServer.handle(req, res);
    }

    appCallback(req, res);
});

server.listen(port)

Use tus-node with Fastify

const tus = require('tus-node');
const tusServer = new tus.Server();
tusServer.datastore = new tus.FileStore({
    path: '/files',
});

const fastify = require('fastify')({ logger: true });

/**
 * add new content-type to fastify forewards request 
 * without any parser to leave body untouched
 * @see https://www.fastify.io/docs/latest/Reference/ContentTypeParser/
 */
fastify.addContentTypeParser(
    'application/offset+octet-stream', async () => true
);

/**
 * let tus handle preparation and filehandling requests 
 * fastify exposes raw nodejs http req/res via .raw property
 * @see https://www.fastify.io/docs/latest/Reference/Request/
 * @see https://www.fastify.io/docs/latest/Reference/Reply/#raw
 */
fastify.all('/files', (req, res) => {
    tusServer.handle(req.raw, res.raw);
});
fastify.all('/files/*', (req, res) => {
    tusServer.handle(req.raw, res.raw);
});

fastify.listen(3000, (err) => {
    if (err) {
        fastify.log.error(err);
        process.exit(1);
    }
});

Features

Events:

Execute code when lifecycle events happen by adding event handlers to your server.

const Server = require('tus-node').Server;
const EVENTS = require('tus-node').EVENTS;

const server = new Server();
server.on(EVENTS.EVENT_UPLOAD_COMPLETE, (event) => {
    console.log(`Upload complete for file ${event.file.id}`);
});

• EVENT_FILE_CREATED: Fired when a POST request successfully creates a new file

  Example payload:

  {
      file: {
          id: '7b26bf4d22cf7198d3b3706bf0379794',
          upload_length: '41767441',
          upload_metadata: 'filename NDFfbWIubXA0'
       }
  }

• EVENT_ENDPOINT_CREATED: Fired when a POST request successfully creates a new upload endpoint

  Example payload:

  {
      url: 'http://localhost:1080/files/7b26bf4d22cf7198d3b3706bf0379794'
  }

• EVENT_UPLOAD_COMPLETE: Fired when a PATCH request finishes writing the file

  Example payload:

  {
      file: {
          id: '7b26bf4d22cf7198d3b3706bf0379794',
          upload_length: '41767441',
          upload_metadata: 'filename NDFfbWIubXA0'
      }
  }

• EVENT_FILE_DELETED: Fired when a DELETE request finishes deleting the file

  Example payload:

  {
      file_id: '7b26bf4d22cf7198d3b3706bf0379794'
           
  }

Custom GET handlers:

Add custom GET handlers to suit your needs, similar to Express routing.

const server = new Server();
server.get('/uploads', (req, res) => {
    // Read from your DataStore
    fs.readdir(server.datastore.path, (err, files) => {
        // Format the JSON response and send it
    }
});

Custom file names:

The default naming of files is a random crypto hex string. When using your own namingFunction, make sure to create URL friendly names such as removing spaces.

const crypto = require('crypto');

// req is http.IncomingMessage
const randomString = (req) => {
    // same as the default implementation
    return crypto.randomBytes(16).toString('hex');
}

server.datastore = new tus.FileStore({
    path: '/files',
    namingFunction: randomString
});

Development

Start the demo server using Local File Storage

$ npm run demo

Or start up the demo server using Google Cloud Storage

$ npm run gcs_demo

Then navigate to the demo (localhost:1080) which uses tus-js-client
