Prefix Transform

The prefix transform allows you to prefix GraphQL types and GraphQL root operations (under Query/Mutation).

You can use it to easily "namespace" APIs in your unified API and avoid conflicts.

yarn add @graphql-mesh/transform-prefix

How to use?

Add the following configuration to your Mesh config file:

transforms:
  - prefix:
      mode: bare | wrap
      value: MyApi_
💡

For information about "bare" and "wrap" modes, please read the dedicated section. You can check out our example that uses schema stitching with a PostgreSQL data source and prefix transform. Click here to open the example on GitHub.
