GraphQL Directive: @requiresAuthentication

This directive will throw an AuthenticationError if the context of the query operation that implements this directive does not meet the criteria of "being authenticated".

Usage

To use the directive, you should start by adding the directive to your GraphQL schema SDL:

@directive requiresAuthentication on FIELD_DEFINITION

After this, you can create the directive by passing an isAuthenticated resolver (and optionally a custom error) and the directive will do the rest:

const requiresAuthentication = requiresAuthenticationDirective<Context>({
  isAuthenticated: (context) => !!context.auth?.token,
  throwError: new MyCustomError('WITH_CUSTOM_ERROR_CODE'),
})

new ApolloServer({
  schemaDirectives: {
    requiresAuthentication,
  },
})
