node-stream-json-stringify

JSON.stringify, streaming, non-blocking, for real this time.

JSON.stringify, exactly, except it doesn't block on big objects and returns a readable stream

To be clear, this implementation is way slower than the native JSON.stringify. However, it makes a specific effort not to block the event loop which can be useful for large payloads

Installation

npm install --save stream-json-stringify

Usage

var stringify = require('stream-json-stringify');

stringify(myBigObject).pipe(process.stdout);

As stringify is a readable stream, you can configure it by passing options to it.

stringify(someObject, { highWaterMark: 2048 })

It also accepts a maxIterationTicks as an option to limit the maximum number of times it is going to look for the next token to serialize during a given loop. It defaults to 100.

Test

You can run the tests with npm test. You will need to know mocha
