FAQ

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.

Example:
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

How does it work?

Access control deals in 2 modes: Public/Private schema modes.

The difference between Public and Private schema modes concerns the feedback given to the user when a validation fails. In Public mode, a detailed error message is given to the user (eg: "only users with role 'administrator' can access this field). In Private mode, there is no helpful information, instead the user is told that the field or directive does not exist.

We need to implement 4 cases of access control:

  1. Fields in Public schema mode
  2. Directives in Public schema mode
  3. Fields in Private schema mode
  4. Directives in Private schema mode

In Public schema mode, we can simply add a special directive that will validate the restriction (such as: is the user logged in? does the logged-in user have a specific role or capability?).

In Private mode, we add a hook that filters out the field or directive before it is registered.

In addition, whenever a validation must be performed to know if the user can access a field or directive, the response from the GraphQL server cannot be cached (when using component Cache Control). For the Public mode this situation is automatically handled, since the directive validating if the user is logged in or not already indicates that the response cannot be cached. For the Private mode, however, we need to add a special directive "NoCache". Hence, we need to deal with the following 2 cases:

  1. NoCache for Fields in Private schema mode
  2. NoCache for Directives in Private schema mode
