Connect your Connect project to GlitchTip

Use yarn or npm to add @sentry/node to your project:

# Using yarn
$ yarn add @sentry/node

# Using npm
$ npm install @sentry/node

const connect = require("connect");
const Sentry = require("@sentry/node");

// Must configure Sentry before doing anything else with it
Sentry.init({ dsn: "YOUR-GLITCHTIP-DSN-HERE" });

function mainHandler(req, res) {
  throw new Error("My first GlitchTip error!");
}

function onError(err, req, res, next) {
  // The error id is attached to `res.sentry` to be returned
  // and optionally displayed to the user for support.
  res.statusCode = 500;
  res.end(res.sentry + "\n");
}

connect(
  // The request handler be the first item
  Sentry.handlers.requestHandler(),

  connect.bodyParser(),
  connect.cookieParser(),
  mainHandler,

  // The error handler must be before any other error middleware
  Sentry.handlers.errorHandler(),

  // Optional fallthrough error handler
  onError
).listen(3000);

requestHandler accepts some options that let you decide what data should be included in the event sent to GlitchTip.

Possible options are:

// keys to be extracted from req
request?: boolean | string[]; // default: true = ['cookies', 'data', 'headers', 'method', 'query_string', 'url']
// server name
serverName?: boolean; // default: true
// generate transaction name
//   path == request.path (eg. "/foo")
//   methodPath == request.method + request.path (eg. "GET|/foo")
//   handler == function name (eg. "fooHandler")
transaction?: boolean | 'path' | 'methodPath' | 'handler'; // default: true = 'methodPath'
// keys to be extracted from req.user
user?: boolean | string[]; // default: true = ['id', 'username', 'email']
// node version
version?: boolean; // default: true
// timeout for fatal route errors to be delivered
flushTimeout?: number; // default: 2000

For example, if you want to skip the server name and add just user, you would use requestHandler like this:

app.use(
  Sentry.handlers.requestHandler({
    serverName: false,
    user: ["email"],
  })
);

By default, errorHandler will capture only errors with a status code of 500 or higher. If you want to change it, provide it with the shouldHandleError callback, which accepts middleware errors as its argument and decides, whether an error should be sent or not, by returning an appropriate boolean value.

app.use(
  Sentry.handlers.errorHandler({
    shouldHandleError(error) {
      // Capture all 404 and 500 errors
      if (error.status === 404 || error.status === 500) {
        return true;
      }
      return false;
    },
  })
);
