async-chain-proxy

async-chain-proxy provides method chain interfaces for accessing async methods.

How to use

method chain

class A {
  async foo () {
    console.log('foo')
  }
  async bar () {
    console.log('bar')
  }
}

const chainProxy = require('async-chain-proxy')
const obj = chainProxy(new A())
obj.foo().bar().end()

// output
>foo
>bar

receive a return value

class A {
  async foo () {
    return 'foo'
  }
}
const chainProxy = require('async-chain-proxy')
const obj = chainProxy(new A())
obj.foo().result((v) => console.log(v)).end()

// output
>foo
