  ...createBuiltinActions({

    reader,
  }),
];

return await createRouter({

Things to know

This scaffolder action is meant to be used in a scaffolded Backstage application created by Backstage CLI. If you are using it in a Backstage monorepo, you need to modify the build process to transpile node_modules also.

NB: The path should always point to a proxy entry with the following format: proxy/<proxy-path>/<external-api-path>. i.e.: /proxy/snyk/org/<some-org>/projects or /proxy/circleci/api/projects (the CircleCI proxy path is circleci/api/ but Snyk is just snyk/)

Prefer a no-code Backstage setup?
