Zames

zames converts callback-based functions to Promises and apply currying to arguments.

zames = currify + promisify.

Install

npm i zames --save

API

zames(fn [,ctx])

• fn - function
• ctx - context

zames can take just a function:

const zames = require('zames');

const promise = zames((a, b, fn) => {
    fn(null, a + b);
});

const add = promise('hello ');

add('world').then((a) => {
    console.log(a);
    // output
    'hello world';
});

Or can be used with ctx as well:

const ctx = {
    error: 'hello',
    log: function(a, b, fn) {
        fn(this.error);
    }
}

const withContext = zames(ctx.log, ctx);

withContext(1, 2)
    .catch((e) => {
        console.error(e.message);
        // output
        'hello';
    });
