promisify.es6

Promisify a callback-based function.

Why Another Promisify Module?

• Only 10 LOC (and, therefore, much smaller than node-promisify and promisify-node, for example).

• Simple and clean code (thanks to ES6 features, such as, arrow functions and the spread operator).

• No dependencies.

• 100% test coverage.

Installation

npm install --save promisify.es6

Example

const promisify = require('promisify.es6')

function sum (a, b, callback) {
  callback(null, a + b)
}

let promisifiedSum = promisify(sum)

promisifiedSum(1, 2).then(sum => {
  console.log(sum) // --> 3
})
