es6-promisify

Converts callback-based functions to Promises, using a boilerplate callback function.

Install

Install with npm

1npm install es6-promisify

Example

1const {promisify} = require("es6-promisify");
2
3// Convert the stat function
4const fs = require("fs");
5const stat = promisify(fs.stat);
6
7// Now usable as a promise!
8try {
9    const stats = await stat("example.txt");
10    console.log("Got stats", stats);
11} catch (err) {
12    console.error("Yikes!", err);
13}

Promisify methods

1const {promisify} = require("es6-promisify");
2
3// Create a promise-based version of send_command
4const redis = require("redis").createClient(6379, "localhost");
5const client = promisify(redis.send_command.bind(redis));
6
7// Send commands to redis and get a promise back
8try {
9    const pong = await client.ping();
10    console.log("Got", pong);
11} catch (err) {
12    console.error("Unexpected error", err);
13} finally {
14    redis.quit();
15}

Handle multiple callback arguments, with named parameters

1const {promisify} = require("es6-promisify");
2
3function test(cb) {
4    return cb(undefined, 1, 2, 3);
5}
6
7// Create promise-based version of test
8test[promisify.argumentNames] = ["one", "two", "three"];
9const multi = promisify(test);
10
11// Returns named arguments
12const result = await multi();
13console.log(result); // {one: 1, two: 2, three: 3}

Provide your own Promise implementation

1const {promisify} = require("es6-promisify");
2
3// Now uses Bluebird
4promisify.Promise = require("bluebird");
5
6const test = promisify(cb => cb(undefined, "test"));
7const result = await test();
8console.log(result); // "test", resolved using Bluebird
