Project has been moved

Please find the new home for Velocita at GMTA Velocita-Proxy.

To upgrade to the new image, simply replace the image isaaceindhoven/velocita-proxy by gmta/velocita-proxy. All tags are still available in the new repository.

Velocita

Velocita is a caching reverse proxy for Composer repositories and package distribution locations, such as Packagist or GitHub.

• Speeds up downloads for package metadata and dist files
• Serves cached files even if the source location is unreachable
• Can be used as a shared cache by multiple developers, CI, etc.
• No changes required to your project's files!

Installation

There are two parts to Velocita:

• Velocita Proxy, a caching reverse proxy
• Composer-velocita, a plugin which instructs Composer to use a Velocita Proxy instance

Running Velocita Proxy

Velocita is available as a Docker image. There are two supported ways to run this image:

Using docker compose

1. Clone this repository:

   git clone https://github.com/isaaceindhoven/velocita-proxy
   cd velocita-proxy
   

2. Copy .env.dist to .env

3. Edit .env and set:

   • VELOCITA_URL: the URL (e.g. https://mydomain.tld) on which Velocita is hosted
   • VELOCITA_TLS_ENABLED: set to true to enable HTTPS
   • VELOCITA_TLS_CERT_FILE: the path to your X.509 PEM-encoded certificate (or chain) for the domain
   • VELOCITA_TLS_KEY_FILE: the path to the private key associated with the certificate

4. Start Velocita:

   docker compose -f docker-compose.yml -f docker-compose.https.yml up -d
   

5. Done!

Using docker

Alternatively, you can run the Docker image directly: see the image's usage instructions.

Using Composer-velocita

Composer-velocita is a Composer plugin that redirects downloads to your Velocita instance for all repositories it supports.

Run the following commands on the machine where you want to enable Velocita, replacing https://url.to.your.velocita.tld/ with the URL of your instance:

composer global config allow-plugins.isaac/composer-velocita true
composer global require isaac/composer-velocita
composer velocita:enable https://url.to.your.velocita.tld/

And you're all set!

Configuration

See the Docker image instructions for environment variables that you can use to configure the proxy's behavior.

Performance

Velocita can give you major performance improvements when a package is not present in the local cache. For example, installing the PHPUnit dependencies from composer.lock:

Command: composer install --profile after composer require phpunit/phpunit:9.5.19 and clearing both the local cache and the vendor folder.

Velocita works great together with Symfony Flex:

Command: composer create-project symfony/skeleton:v6.0.99 symfony --profile after clearing the local cache.

Benchmark setup:

• Velocita is configured with mirrors for Packagist and GitHub Codeload
• PHP version 8.1.4
• Composer version 2.2.10
• Symfony Flex 2.1.6
