proximify

Promisify using ES6 Proxy

Like bluebird's promisifyAll, but using ES6 Proxy which enables it to be:

• Dynamic - lets you add/remove properties
• Deep - works at any depth

Install

npm i proximify

Usage

Example

import Koa from 'koa';
import http from 'http';
import proximify from 'proximify'

const app = proximify(new Koa());

// Works on properties added later on, and at any depth

app.server = http.createServer(app.callback());
app.server.listenAsync(3000).then(...)

API

proximify(target, options)

• target [object](required) Object whose methods need to be patched.

• options [object]:

  • deep [boolean](default:true): If true, applies to child properties recursively

  • store [boolean](default:true): If true, stores the proxy in place of original property (i.e. replaces the original property with its proxy)

  • applyOnData [boolean](default:true): If true, applies to any objects returned (resolved as promise) by the async methods. (equivalent of doing proximify(...) on objects returned from async function)

    const io1 = proximify(new IO(server))
    const io2 = proximify(new IO(server), {applyOnData: false})
    
    const socket1 = io.onceAsync('connection')
    const socket2 = io.onceAsync('connection')
    
    const data1 = socket.onceAsync('test') // works ok
    const data2 = socket.onceAsync('test') // error "onceAsync" undefined

  • suffix [string](default:'Async'): Suffix to use to invoke the promisified version of the method.

  • filter [function]: (Not yet implemented)

  • promisifier [function]: (Not yet implemented)
