npm

Did you ever do this?

console.log(JSON.stringify(object))

This package supports this use case, except properly, so:

• pretty printing by default
• with final comma for all multiline data structures
• support for special values like null, undefined, -0, infinities, NaN
• support for Date, Map, and Set
• partial support WeakMap, and WeakSet (full support is impossible without special engine hooks)

If you're in browser, the browser will usually provide a much better interface than this package. But if you need to print some objects to terminal, send them to logs etc., this package could be very useful.

Future plans

• custom identation (not just 2 spaces)
• support for other JS-style languages like Imba, CoffeeScript etc.
