datocms-plugin-netlify-identity/lib/generateHandler.js

A plugin that nicely displays Netlify identity user info instead of the raw ID

const fetch = require('./utils/fetchJson');
const responders = require('./utils/responders');

function generateHandler(accessToken) {
  return function handler(event, context) {
    try {
      const { id: userId } = event.queryStringParameters;

      if (event.httpMethod === 'OPTIONS') {
        return responders.succeed({});
      }

      if (!userId) {
        return responders.fail('ID_PARAMETER_NEEDED', 'You need to pass an ID query string');
      }

      if (event.httpMethod !== 'GET') {
        return responders.fail('INVALID_REQUEST', 'Invalid request!');
      }

      const { authorization } = event.headers;
      const expectedAuthorization = `Bearer ${accessToken}`;

      if (authorization !== expectedAuthorization) {
        return responders.fail(
          'ACCESS_TOKEN_REQUIRED',
          'You need to pass an Authorization header with the correct access token',
          401
        );
      }

      const { identity } = context.clientContext;

      const userUrl = `${identity.url}/admin/users/${userId}`;

      return fetch(userUrl, identity.token)
        .then(user => responders.succeed(user))
        .catch((e) => {
          console.log(e);
          return responders.fail('EXCEPTION', e.message, e.code || 500)
        });

    } catch(e) {
      console.log(e);
      console.log(e.stack);
      return responders.fail('EXCEPTION', e.message, 500)
    }
  }
}
