# Apex Node.js
Node.js module that makes AWS Lambda's user experience a little nicer.
```js
export default λ(e => 'Hello World')
```
## Installation
```
$ npm install --save apex.js
```
## Features
- return promises
- return results
- actually report uncaught errors (Lambda does not)
## Example
The following example fetches some urls and reports the response status of each. The context and callback are also passed, but are not
shown here.
```js
import axios from 'axios'
import λ from 'apex.js'
import 'babel-polyfill'
export default λ(e => {
console.log('fetching %d urls', e.urls.length)
return Promise.all(e.urls.map(async (url) => {
console.log('fetching %s', url)
return {
status: (await axios.get(url)).status,
url
}
}))
})
```
Without this module it looks something like the following, as Lambda does not try/catch, and the Context
provided has awkward method names that are not idiomatic, or you must use the callback.
```js
import axios from 'axios'
import 'babel-polyfill'
// Vanilla Lambda function.
export default async (e, ctx, cb) => {
console.log('fetching %d urls', e.urls.length)
try {
const res = await Promise.all(e.urls.map(async (url) => {
console.log('fetching %s', url)
return {
status: (await axios.get(url)).status,
url
}
}))
// or ctx.succeed(res);
cb(null, res);
} catch (err) {
// or ctx.fail(err);
cb(err);
}
}
```
