A standard and framework agnostic PHP library to facilitate the implementation of the WOPI protocol.


The Web Application Open Platform Interface (WOPI) protocol let you integrate Office for the web with your application. The WOPI protocol enables Office for the web to access and change files that are stored in your service.

Office for the web platforms:


composer require champs-libres/wopi-lib


There are many different ways to store documents in an application. Therefore, this library does not provide a specific implementation of the WOPI protocol described through the WOPI interface.

Thus, this library mostly provides abstractions and few service implementations.

It provides:

In order to be foster interoperability and be used across many different frameworks, this library uses PSR7, PSR17, PSR18 and PSR12 conventions from the PHP-FIG.

Symfony integration

There is already an implementation of the library in Symfony through the champs-libres/wopi-bundle package.


Code quality, tests, benchmarks

Every time changes are introduced into the library, Github runs the tests.

The library has tests written with PHPSpec. Feel free to check them out in the spec directory. Run composer phpspec to trigger the tests.

Before each commit, some inspections are executed with GrumPHP; run composer grumphp to check manually.

The quality of the tests is tested with Infection a PHP Mutation testing framework, run composer infection to try it.

Static analyzers are also controlling the code. PHPStan and PSalm are enabled to their maximum level.


Feel free to contribute to this project by submitting pull requests on Github.
