How to trim whitespaces from JSON output in Node.js?

Question

On Node.js using Express, I am outputting JSON with a simple response.send(myObject) It's working fine, but the response has a lot of white spaces indentations. Removing them reduces the size by half. Is there a quick/proper way to do this? I tried using JSON.stringify and it works great, but that turns the response type to text/html

Check the express settings its one of the settings (json spaces off the top of my head). It's automatically 0 on production mode. — Jonathan Ong

Awesome! Looks like Express will actually automatically remove the white spaces in production env. More info here. So no changes needed.

Wow I added this to my app and it made js-yaml's output nice and spaceless!

you can also compress your output which will remove uncessary whitespaces by gzipping it.

  app.use(express.compress());
