async-chainable-flush v1.0.0

async-chainable-flush

Plugin for async-chainable that flushes various output streams before continuing.

This is mainly useful for CLI based scripts which need to ensure process.stdout + process.stderr have output their contents before exiting.

var asyncChainable = require('async-chainable');
var asyncChainableFlush = require('async-chainable-flush');

asyncChainable()
	.use(asyncChainableFlush)

	.then(function(next) {
		for (var i = 0; i < 1000; i++) {
			console.log('I =', i);
		}
		next();
	})
	.flush() // Assumes process.stdout + process.stderr if nothing is specified
	.end();

API

The async-chainable-flush API exposes a single API call flush() which can take any number of streams to wait for before continuing. If no streams are specified process.stdout and process.stderr are assumed.

asyncChainable()
	.use(asyncChainableFlush)

	.then(function(next) {
		for (var i = 0; i < 1000; i++) {
			console.log('I =', i);
		}
		next();
	})
	.flush(process.stdout) // Only wait for process.stdout to flush before continuing
	.end();
