Migrate legacy res.send(obj, status), res.send(status), res.json(obj, status) and res.jsonp(obj, status)

Migrates usage of the legacy APIs res.send(obj, status), res.json(obj, status), and res.jsonp(obj, status) to use the recommended approach of specifying the status code using the res.status(status).send(obj), res.status(status).json(obj), and res.status(status).jsonp(obj) methods respectively. The older APIs that allowed specifying the status code as a second argument have been deprecated.

Example

Migrating res.send(obj, status)

The migration involves replacing instances of res.send(obj, status) with res.status(status).send(obj).

app.get('/some-route', (req, res) => {
  // Some logic here
- res.send(obj, status);
+ res.status(status).send(obj);
});

Migrating res.json(obj, status)

The migration involves replacing instances of res.json(obj, status) with res.status(status).json(obj).

app.get('/some-route', (req, res) => {
  // Some logic here
- res.json(obj, status);
+ res.status(status).json(obj);
});

Migrating res.jsonp(obj, status)

The migration involves replacing instances of res.jsonp(obj, status) with res.status(status).jsonp(obj).

app.get('/some-route', (req, res) => {
  // Some logic here
- res.jsonp(obj, status);
+ res.status(status).jsonp(obj);
});

Migrating res.send(status)

The migration involves replacing instances of res.send(status) with res.sendStatus(status).

app.get('/some-route', (req, res) => {
  // Some logic here
- res.send(status);
+ res.sendStatus(status);
});
