Graph visualization for your project's composer.json and its dependencies:

dependency graph for clue/graph-composer

Table of contents


Once clue/graph-composer is installed, you can use it via command line like this.

graph-composer show

The show command creates a dependency graph for the given project path and opens the default desktop image viewer for you:

$ php graph-composer.phar show ~/path/to/your/project
  • It accepts an optional argument which is the path to your project directory or composer.json file (defaults to checking the current directory for a composer.json file).

  • You may optionally pass an --format=[svg/svgz/png/jpeg/...] option to set the image type (defaults to svg).

graph-composer export

The export command works very much like the show command, but instead of opening your default image viewer, it will write the resulting graph to STDOUT or into an image file:

$ php graph-composer.phar export ~/path/to/your/project
  • It accepts an optional argument which is the path to your project directory or composer.json file (defaults to checking the current directory for a composer.json file).

  • It accepts an additional optional argument which is the path to write the resulting image to. Its file extension also sets the image format (unless you also explicitly pass the --format option). Example call:

    $ php graph-composer.phar export ~/path/to/your/project export.png

    If this argument is not given, it defaults to writing to STDOUT, which may be useful for scripting purposes:

    $ php graph-composer.phar export ~/path/to/your/project | base64
  • You may optionally pass an --format=[svg/svgz/png/jpeg/...] option to set the image type (defaults to svg).


You can grab a copy of clue/graph-composer in either of the following ways.

This project aims to run on any platform and thus does not require any PHP extensions and supports running on legacy PHP 5.3 through current PHP 7+ and HHVM. It's highly recommended to use PHP 7+ for this project.

The graph drawing feature is powered by the excellent GraphViz software. This means you'll have to install GraphViz (dot executable). The Graphviz homepage includes complete installation instructions for most common platforms, users of Debian/Ubuntu-based distributions may simply invoke:

$ sudo apt install graphviz

As a phar (recommended)

Once you have PHP and GraphViz installed, you can simply download a pre-packaged and ready-to-use version of this project as a Phar to any directory. You can simply download the latest graph-composer.phar file from our releases page. The latest release can always be downloaded like this:

$ curl -OL

That's it already. Once downloaded, you can verify everything works by running this:

$ cd ~/Downloads
$ php graph-composer.phar --version

If you prefer a global (system-wide) installation without having to type the .phar extension each time, you may simply invoke:

$ chmod +x graph-composer.phar
$ sudo mv graph-composer.phar /usr/local/bin/graph-composer

You can verify everything works by running:

$ graph-composer --version

There's no separate update procedure, simply download the latest release again and overwrite the existing phar.

Installation using Composer

Alternatively, you can also install clue/graph-composer as part of your development dependencies. You will likely want to use the require-dev section to exclude clue/graph-composer in your production environment.

This method also requires PHP 5.3+, GraphViz and, of course, Composer.

You can either modify your composer.json manually or run the following command to include the latest tagged release:

$ composer require --dev clue/graph-composer

Now you should be able to invoke the following command in your project root:

$ ./vendor/bin/graph-composer show

Alternatively, you can install this globally for your user by running:

$ composer global require clue/graph-composer

Now, assuming you have ~/.composer/vendor/bin in your path, you can invoke the following command:

$ graph-composer show ~/path/to/your/project

Note: You should only invoke and rely on the main graph-composer bin file. Installing this project as a non-dev dependency in order to use its source code as a library is not supported.

To update to the latest release, just run composer update clue/graph-composer. If you installed it globally via composer you can run composer global update clue/graph-composer instead.


clue/graph-composer is an open-source project and encourages everybody to participate in its development. You're interested in checking out how clue/graph-composer works under the hood and/or want to contribute to the development of clue/graph-composer? Then this section is for you!

The recommended way to install clue/graph-composer is to clone (or download) this repository and use Composer to download its dependencies. Therefore you'll need PHP, Composer, GraphViz, git and curl installed. For example, on a recent Ubuntu/debian system, simply run:

$ sudo apt install php7.2-cli git curl graphviz

$ git clone
$ cd graph-composer

$ curl -s | php
$ sudo mv composer.phar /usr/local/bin/composer

$ composer install

You can now verify everything works by running clue/graph-composer like this:

$ php bin/graph-composer show

If you want to distribute clue/graph-composer as a single standalone release file, you may compile the project into a single graph-composer.phar file like this:

$ composer build

Note that compiling will temporarily install a copy of this project to the local build/ directory and install all non-development dependencies for distribution. This should only take a second or two if you've previously installed its dependencies already. The build script optionally accepts the version number (VERSION env) and an output file name or will otherwise try to look up the last release tag, such as graph-composer-1.0.0.phar.

You can now verify the resulting graph-composer.phar file works by running it like this:

$ ./graph-composer.phar --version

To update your development version to the latest version, just run this:

$ git pull
$ php composer.phar install
