Resumable file upload in PHP using tus resumable upload protocol v1.0.0
Medium Article ⚡ Laravel & Lumen Integration ⚡ Symfony Integration ⚡ CakePHP Integration ⚡ WordPress Integration
tus is a HTTP based protocol for resumable file uploads. Resumable means you can carry on where you left off without re-uploading whole data again in case of any interruptions. An interruption may happen willingly if the user wants to pause, or by accident in case of a network issue or server outage.

Installation
Pull the package via composer.
$ composer require ankitpokhrel/tus-php
// Use v1 for php7.1, Symfony 3 or 4.
$ composer require ankitpokhrel/tus-php:^1.2
Usage
Server
This is how a simple server looks like.
// server.php // Either redis, file or apcu. Leave empty for file based cache. $server = new \TusPhp\Tus\Server('redis'); $response = $server->serve(); $response->send(); exit(0); // Exit from current PHP process.
‼️ File based cache is not recommended for production use.
You need to rewrite your server to respond to a specific endpoint. For example:
Nginx
# nginx.conf location /files { try_files $uri $uri/ /server.php?$query_string; }
A new config option fastcgi_request_buffering is available since nginx 1.7.11. When buffering is enabled, the entire request body is read from the client before sending the request to a FastCGI server. Disabling this option might help with timeouts during the upload. Furthermore, it helps if you’re running out of disc space on the tmp partition of your system.
If you do not turn off fastcgi_request_buffering
and you use fastcgi
, you will not be able to resume uploads because nginx will not give the request back to PHP until the entire file is uploaded.
location ~ \.php$ { # ... fastcgi_request_buffering off; # Disable request buffering # ... }
A sample nginx configuration can be found here.
Apache
# .htaccess RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^files/?(.*)?$ /server.php?$1 [QSA,L]
Default max upload size is 0 which means there is no restriction. You can set max upload size as described below.
$server->setMaxUploadSize(100000000); // 100 MB in bytes
Default redis and file configuration for server and client can be found inside config/server.php
and config/client.php
respectively.
To override default config you can simply copy the file to your preferred location and update the parameters. You then need to set the config before doing anything else.
\TusPhp\Config::set('<path to your config>'); $server = new \TusPhp\Tus\Server('redis');
Alternately, you can set REDIS_HOST
, REDIS_PORT
and REDIS_DB
env in your server to override redis settings for both server and client.
Client
The client can be used for creating, resuming and/or deleting uploads.
$client = new \TusPhp\Tus\Client($baseUrl); // Key is mandatory. $key = 'your unique key'; $client->setKey($key)->file('/path/to/file', 'filename.ext'); // Create and upload a chunk of 1MB $bytesUploaded = $client->upload(1000000); // Resume, $bytesUploaded = 2MB $bytesUploaded = $client->upload(1000000); // To upload whole file, skip length param $client->file('/path/to/file', 'filename.ext')->upload();
To check if the file was partially uploaded before, you can use getOffset
method. It returns false if the upload
isn't there or invalid, returns total bytes uploaded otherwise.
$offset = $client->getOffset(); // 2000000 bytes or 2MB
Delete partial upload from the cache.
$client->delete($key);
By default, the client uses /files
as an API path. You can change it with setApiPath
method.
$client->setApiPath('/api');
By default, the server will use sha256
algorithm to verify the integrity of the upload. If you want to use a different hash algorithm, you can do so by
using setChecksumAlgorithm
method. To get the list of supported hash algorithms, you can send OPTIONS
request to the server.
$client->setChecksumAlgorithm('crc32');
Third Party Client Libraries
Uppy
Uppy is a sleek, modular file uploader plugin developed by same folks behind tus protocol. You can use uppy to seamlessly integrate official tus-js-client with tus-php server. Check out more details in uppy docs.
uppy.use(Tus, { endpoint: 'https://tus-server.yoursite.com/files/', // use your tus endpoint here resume: true, autoRetry: true, retryDelays: [0, 1000, 3000, 5000] })
Tus-JS-Client
Tus-php server is compatible with the official tus-js-client Javascript library.
var upload = new tus.Upload(file, { endpoint: "/tus", retryDelays: [0, 3000, 5000, 10000, 20000], metadata: { name: file.name, type: file.type } }) upload.start()
Cloud Providers
Many cloud providers implement PHP streamWrapper interface that enables us to store and retrieve data from these providers using built-in PHP functions. Since tus-php relies on PHP's built-in filesystem functions, we can easily use it to upload files to the providers like Amazon S3 if their API supports writing in append binary mode. An example implementation to upload files directly to S3 bucket is as follows:
// server.php // composer require aws/aws-sdk-php use Aws\S3\S3Client; use TusPhp\Tus\Server; use Aws\Credentials\Credentials; $awsAccessKey = 'AWS_ACCESS_KEY'; // YOUR AWS ACCESS KEY $awsSecretKey = 'AWS_SECRET_KEY'; // YOUR AWS SECRET KEY $awsRegion = 'eu-west-1'; // YOUR AWS BUCKET REGION $basePath = 's3://your-bucket-name'; $s3Client = new S3Client([ 'version' => 'latest', 'region' => $awsRegion, 'credentials' => new Credentials($awsAccessKey, $awsSecretKey) ]); $s3Client->registerStreamWrapper(); $server = new Server('file'); $server->setUploadDir($basePath); $response = $server->serve(); $response->send(); exit(0);
Extension Support
- The Creation extension is mostly implemented and is used for creating the upload. Deferring the upload's length is not possible at the moment.
- The Termination extension is implemented which is used to terminate completed and unfinished uploads allowing the Server to free up used resources.
- The Checksum extension is implemented, the server will use
sha256
algorithm by default to verify the upload. - The Expiration extension is implemented, details below.
- This Concatenation extension is implemented except that the server is not capable of handling unfinished concatenation.
Expiration
The Server is capable of removing expired but unfinished uploads. You can use the following command manually or in a cron job to remove them. Note that this command checks your cache storage to find expired uploads. So, make sure to run it before the cache is expired, else it will not find all files that needs to be cleared.
$ ./vendor/bin/tus tus:expired --help Usage: tus:expired [<cache-adapter>] [options] Arguments: cache-adapter Cache adapter to use: redis, file or apcu [default: "file"] Options: -c, --config=CONFIG File to get config parameters from. eg: $ ./vendor/bin/tus tus:expired redis Cleaning server resources ========================= 1. Deleted 1535888128_35094.jpg from /var/www/uploads
You can use--config
option to override default redis or file configuration.
$ ./vendor/bin/tus tus:expired redis --config=<path to your config file>
Concatenation
The Server is capable of concatenating multiple uploads into a single one enabling Clients to perform parallel uploads and to upload non-contiguous chunks.
// Actual file key $uploadKey = uniqid(); $client->setKey($uploadKey)->file('/path/to/file', 'chunk_a.ext'); // Upload 10000 bytes starting from 1000 bytes $bytesUploaded = $client->seek(1000)->upload(10000); $chunkAkey = $client->getKey(); // Upload 1000 bytes starting from 0 bytes $bytesUploaded = $client->setFileName('chunk_b.ext')->seek(0)->upload(1000); $chunkBkey = $client->getKey(); // Upload remaining bytes starting from 11000 bytes (10000 + 1000) $bytesUploaded = $client->setFileName('chunk_c.ext')->seek(11000)->upload(); $chunkCkey = $client->getKey(); // Concatenate partial uploads $client->setFileName('actual_file.ext')->concat($uploadKey, $chunkBkey, $chunkAkey, $chunkCkey);
Additionally, the server will verify checksum against the merged file to make sure that the file is not corrupt.
Events
Often times, you may want to perform some operation after the upload is complete or created. For example, you may want to crop images after upload or transcode a file and email it to your user. You can utilize tus events for these operations. Following events are dispatched by server during different point of execution.
Responding to an Event
To listen to an event, you can simply attach a listener to the event name. An TusEvent
instance is created and passed to all of the listeners.
$server->event()->addListener('tus-server.upload.complete', function (\TusPhp\Events\TusEvent $event) { $fileMeta = $event->getFile()->details(); $request = $event->getRequest(); $response = $event->getResponse(); // ... });
or, you can also bind some method of a custom class.
/** * Listener can be method from any normal class. */ class SomeClass { public function postUploadOperation(\TusPhp\Events\TusEvent $event) { // ... } } $listener = new SomeClass(); $server->event()->addListener('tus-server.upload.complete', [$listener, 'postUploadOperation']);
Middleware
You can manipulate request and response of a server using a middleware. Middleware can be used to run a piece of code before a server calls the actual handle method. You can use middleware to authenticate a request, handle CORS, whitelist/blacklist an IP etc.
Creating a Middleware
In order to create a middleware, you need to implement TusMiddleware
interface. The handle method provides request and response object for you to manipulate.
<?php namespace Your\Namespace; use TusPhp\Request; use TusPhp\Response; use TusPhp\Middleware\TusMiddleware; class Authenticated implements TusMiddleware { // ... /** * {@inheritDoc} */ public function handle(Request $request, Response $response) { // Check if user is authenticated if (! $this->user->isLoggedIn()) { throw new UnauthorizedHttpException('User not authenticated'); } $request->getRequest()->headers->set('Authorization', 'Bearer ' . $this->user->token()); } // ... }
Adding a Middleware
To add a middleware, get middleware object from server and simply pass middleware classes.
$server->middleware()->add(Authenticated::class, AnotherMiddleware::class);
Or, you can also pass middleware class objects.
$authenticated = new Your\Namespace\Authenticated(new User()); $server->middleware()->add($authenticated);
Skipping a Middleware
If you wish to skip or ignore any middleware, you can do so by using the skip
method.
$server->middleware()->skip(Cors::class, AnotherMiddleware::class);
Setting up a dev environment and/or running examples locally
An ajax based example for this implementation can be found in examples/
folder. You can build and run it using docker as described below.
Docker
Make sure that docker and docker-compose are installed in your system. Then, run docker script from project root.
# PHP7 $ make dev # PHP8 $ make dev8 # or, without make # PHP7 $ bin/docker.sh # PHP8 $ PHP_VERSION=8 bin/docker.sh
Now, the client can be accessed at http://0.0.0.0:8080 and the server can be accessed at http://0.0.0.0:8081. The default API endpoint is set to/files
and uploaded files can be found inside uploads
folder. All docker configs can be found in docker/
folder.
If you want a fresh start then you can use the following commands. It will delete and recreate all containers, images, and uploads folder.
# PHP7 $ make dev-fresh # PHP8 $ make dev8-fresh # or, without make # PHP7 $ bin/clean.sh && bin/docker.sh # PHP8 $ bin/clean.sh && PHP_VERSION=8 bin/docker.sh
We also have some utility scripts that will ease your local development experience. See Makefile for a list of all available commands. If you are not using make, then you can use shell scripts available here.
