After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Usage

Here's an example that will perform the default Lighthouse audits and store the result in report.json (You can use the Lighthouse Viewer to open the report):

Output

The setOutput method accepts a second argument that can be used to specify the format (json,html). If the format argument is missing then the file extension will be used to determine the output format. If the file extension does not specify an accepted format, then json will be used.

You can output both the json and html reports by passing an array as the second argument. For the example the following code will create two reports example.report.html and example.report.json.

Using a custom config

You can provide your own configuration file using the withConfig method.

You can also pass a php array to the withConfig method containing your configuration.

Note: in order to use an array to specify the configuration options, php needs to be able to create and move temporary files.

Details about the configuration options can be found here
