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

``typescript
import * as tp from 'typed-promisify';
`

$3

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

Example:
`typescript
var stat = tp.promisify(fs.stat);

stat('test.txt')
.then(stats => console.log(stats));
`

$3

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:
`typescript
var stat = tp.promisify(fs.stat);
var elts = ['test.txt', 'test2.txt'];

tp.map(elts, stat)
.then(stats => console.log(stats));
`

$3

Call a synchronous function to kick off a promise chain.

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