Abet

Abet allows promises to be chained using the properties and methods of their results.

Install

npm install abet

Example

const promise = Promise.resolve({
  users: [
    {name: 'joe', age: 10},
    {name: 'sally', age: 20},
  ]
});

abet(promise)
  .users
  .reduce((a, b) => {
    if(a.age > b.age) return a;
    return b;
  })
  .name
  .then(name => console.log(name)); // prints 'sally'
  

Or using async/await:

const { name } = await abet(promise)
  .users
  .reduce((a, b) => {
    if(a.age > b.age) return a;
    return b;
  });
  
console.log(name); // prints 'sally'

How it works

Abet relies on ES6 Proxies to keep track of keys being accessed and methods being called. When then or catch is called on a wrapped promise, the result is intercepted and reduced using the keys and methods used on the wrapper.
