# resolve-chain

Chains pending promises and captures resolved return values

## Usage

```js

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']

```
