# Proxymise

[![npm](https://img.shields.io/npm/v/proxymise.svg)](https://www.npmjs.com/package/proxymise)

Chainable Promise Proxy.

Lightweight ES6 [Proxy] for [Promises] with no additional dependencies. Proxymise allows for method

and property chaining without need for intermediate `then()` or `await` for cleaner and simpler code.

[Proxy]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy

[Promises]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise

## Use

```shell

npm i proxymise

```

```javascript

const proxymise = require('proxymise');

// Instead of thens

foo.then(value => value.bar())

  .then(value => value.baz())

  .then(value => value.qux)

  .then(value => console.log(value));

// Instead of awaits

const value1 = await foo;

const value2 = await value1.bar();

const value3 = await value2.baz();

const value4 = await value3.qux;

console.log(value4);

// Use proxymise

const value = await proxymise(foo).bar().baz().qux;

console.log(value);

```

## Practical Examples

- [Fetch and parse JSON](https://github.com/kozhevnikov/proxymise/blob/master/test/fetch.test.js)

- [Amazon DynamoDB get item](https://github.com/kozhevnikov/proxymise/blob/master/test/dynamodb.test.js)

- [Selenium WebDriverJS and Page Objects](https://github.com/kozhevnikov/proxymise/blob/master/test/selenium.test.js)

## Performance

Proxymised [benchmark] with 10000 iterations is practically as performant as the non-proxymised one.

[benchmark]: https://github.com/kozhevnikov/proxymise/blob/master/test/benchmark.js

```shell

node test/benchmark.js 

with proxymise: 3907.582ms

without proxymise: 3762.375ms

```
