    typed-promisify

    Typescript promise helpers: promisify(), map(), and _try(). You will need ES6 promises. These helpers preserve types in the promises, enabling better typechecking and VS Code intellisense:

    API

    import * as tp from 'typed-promisify';

    promisify(fn)

    Convert a node style callback function to one returning a promise.

    Example:

    var stat = tp.promisify(fs.stat);
     
    stat('test.txt')
        .then(stats => console.log(stats));

    map(elts, fn)

    Promise aware map.

    Elts can be a promise for an array, an array of promises, or a promise for an array of promises. Fn can be synchronous or return a promise.

    Returns a promises that resolves when all applied promises resolve (similar to Promise.all).

    Example:

    var stat = tp.promisify(fs.stat);
    var elts = ['test.txt', 'test2.txt'];
     
    tp.map(elts, stat)
        .then(stats => console.log(stats));

    _try(fn, arg1, arg2...)

    Call a synchronous function to kick off a promise chain.

    Example:

    tp._try(fs.writeFileSync, 'test.txt', 'hello world')
        .then(() => {
            //do other stuff
        })
        .then(() => console.log('sucess'))
        .catch(err => console.log('failure'));
