# lazy-resolver

Skip hoops with promises

```bash

npm install lazy-resolver

```

Do you know how lodash _.get works or angulars $parse works?

this lib is kind of like that, you can test deep objects/path

but it dose it with promises and by chaining a dummy function

to evaluate the code when a promise has been resolved

# Example:

```js

const resolve = require('lazy-resolver') // This is a Proxy handler

const fetch = resolve(import('node-fetch')).default

fetch(url)

  .then(response => console.log(response))

```

Go beond what's possible and make promise chain sync-ish looking

```js

// Node variant

const fetch = resolve(import('node-fetch')).default

fetch('https://httpbin.org/get?items=4&items=2')

  .json()

  .args

  .items

  .map(n => ~~n * 4)

  .then(console.log, console.warn)

// Browser variant

resolve(window)

  .fetch('https://httpbin.org/get?items=4&items=2')

  .json()

  .args

  .items

  .map(n => ~~n * 4)

  .forEach(n => console.log(n))

```

Test if obj exist, similar to lodash/get or optional chaining

```js

const obj = {}

exist = await resolve(obj).foo.bar().buz[28]

```
