Policies

The following policies are available:

• policy.authenticate: Verifies a Firebase ID token (JWT) validity.

Authenticate

This policy does 3 things:

1. Ensure the token is present in the authorization header.
2. It is prefixed with Bearer with trailing space.
3. Token is valid and not expired using Firebase Admin SDK.

feature('UsersFeature', {
  policies: {
    isAuthenticated: policy.authenticate(),
  },
  workflows: [
    workflow('GetUser', {
      trigger: trigger.http({
        policies: ['isAuthenticated'],
        method: 'get',
        path: '/user/:id',
      }),
      execute: async ({ trigger }) => {
        // do something
      },
    }),
  ],
});

In this example, the isAuthenticated policy is applied to the GetUser workflow which means that the workflow will only be executed if the Firebase ID token is valid.
