timers/promises for client and server.

The timers/promises API provides an alternative set of timer functions that return Promise objects.

npm install isomorphic-timers-promises --save

import {
	setTimeout,
	setImmediate,
	setInterval
} from 'isomorphic-timers-promises';

(async () => {
	const result = await setTimeout(100, 'becky');
	console.log(result); // 'becky'
})();

(async () => {
	const result = await setImmediate('maya');
	console.log(result); // 'maya'
})();

(async () => {
	let result = 0;
	for await (const startTime of setInterval(100, Date.now())) {
		const now = Date.now();
		result = result + 1;
		if (now - startTime >= 1000) {
			break;
		}
	}
	console.log(result); // 10
})();

// webpack.config.js
module.exports = {
	// ...
	resolve: {
		alias: {
			'timers/promises': 'isomorphic-timers-promises'
		}
	}
};

// rollup.config.js
const { default: resolve } = require('@rollup/plugin-node-resolve');
const alias = require('@rollup/plugin-alias');

module.exports = {
	// ...
	plugins: [
		resolve(),
		alias({
			entries: {
				'timers/promises': 'isomorphic-timers-promises'
			}
		})
	]
};

Returns: Promise

Returns: Promise

Returns: async iterator that generates values in an interval of delay.

Supports Node 10+.

Tested in Chrome 72, Firefox 65, Internet Explorer 11 and should work in all modern browsers.

Check support based on Browserslist configuration.

Assumes Promise, AbortController and setImmediate are polyfilled or available in global context.

For automated tests, run npm run test:automated (append :watch for watcher support).

Test suite is taken and modified from official Node.js repository (setTimeout, setImmediate, setInterval).
