Node.js 8 the Right Way

Providing an Async Handler Function to Express

Open your lib/bundle.js and add the following inside the module.exports function, after the bundle-creation API you added previously.

web-services/b4/lib/bundle.js

​/**​
​ * Retrieve a given bundle.​
​ * curl http://<host>:<port>/api/bundle/<id>​
​ */​
app.​get​(​'/api/bundle/:id'​, ​async​ (req, res) => {
  ​const​ options = {
    url: ​`​${url}​/​${req.params.id}​`​,
    json: ​true​,
  };

  ​try​ {
    ​const​ esResBody = ​await​ rp(options);
    res.status(200).json(esResBody);
  } ​catch​ (esResErr) {
    res.status(esResErr.statusCode || 502).json(esResErr.error);
  }
});
