res.json()

Sends a JSON response composed of the specified data.

Usage

return res.json(data);

Details

When an object or array is passed to it, this method is identical to res.send(). Unlike res.send(), however, res.json() may also be used for explicit JSON conversion of non-objects (null, undefined, etc.), even though these are technically not valid JSON.

Examples

return res.json({ firstName: 'Tobi' });
return res.status(201).json({ id: 201721 });
var leena = await User.findOne({ firstName: 'Leena' });
if (!leena) { return res.notFound(); }
return res.json(leena.id);//« you can send down primitives, like numbers

Notes

  • Don't forget that this method's name is all lowercase.
  • This method is terminal, meaning that it is generally the last line of code your app should run for a given request (hence the advisory usage of return throughout these docs).

Built with Love

The Sails framework is built by a web & mobile shop in Austin, TX, with the help of our contributors. We created Sails in 2012 to assist us on Node.js projects. Naturally we open-sourced it. We hope it makes your life a little bit easier!
