Chains pending promises and captures resolved return values
Usage
import ResolveChain from 'resolve-chain'
const createPromise = (value) => new Promise((resolve) => resolve(value))
const chain = new ResolveChain()
chain.add(createPromise('hello'))
chain.add(createPromise('world'))
let values = await chain.values() // ['hello', 'world']
chain.add(createPromise('group'))
values = await chain.values() // ['group']
/**
* Handle errors from promise
*/
const error = Promise.reject('error')
chain.add(error, (err) => {
console.log('Oh no some big ol error', err)
})
values = await chain.values() // []
/**
* Return a default value on error
*/
const promise = Promise.reject('error')
.catch((err) => {
return 'some default value'
})
chain.add(promise)
values = await chain.values() // ['some default value']
