Express: res.send() vs res.json() vs res.end()

Materials

• Article res.json() vs res.send() vs res.end() in Express
• MDN: Common MIME types

Key Takeaways

• When in doubt, use .send(). It dynamically sets Content-Type headers to match the data it sends.
• When sending JSON, you can either use .json() or .send().
  • .json() is likely less confusing
  • .json() uses .send() under the hood so the resulting HTTP headers are the same.
