How to generate a client with repo-tools package schema openapi generate client?

Prerequisites

1. Set your OpenAPI file's info.title to your pluginID like so,

info:
  # your pluginId
  title: catalog

2. Find or create a new plugin to house your new generated client. Currently, we do not support generating an entirely new plugin and instead just generate client files.

Generating your client

1. Run yarn backstage-repo-tools package schema openapi generate --client-package <directory>. This will create a new folder in <directory>/src/schema/openapi/generated to house the generated content.
2. You should not need to import anything from subfolders of the src/schema/openapi/generated parent folder, everything you should require will be accessible from the src/schema/openapi/generated/index.ts file. Of note,
3. DefaultApiClient - this is the client that you can use to access your specific spec.
4. Any request or response types - these will be available from the index and should match the names in your spec.
