Babel Runtime for Serverless

Features

• Runs locally and deploys functions written in ES2015 syntax (via Babel)
• Classic and Modern JS Style handlers
• Browserifies, minifies your functions on deployment

Install

Note: Serverless v0.5.0 or higher is required.

• Install via npm in the root of your Serverless Project: npm install serverless-runtime-babel --save
• In the plugins array in your s-project.json add "serverless-runtime-babel"
• All done!

Usage

All you need is to set runtime property of s-function.json to babel. You could use the classic style handler when you need to call context.done() or the modern style when your functions should return a promise.

Classic Style

andler.js */
 strict';

le.exports.handler = function(event, context) {

 Everything is the same but better */
t [name, age, isAdmin] = ['bob', 23, false];
t user = {name, age};

turn context.done(null, {
isAdmin,
userName: user.name,
userAge: user.age
;

Modern JS Style

vent.json */

epos": [
"serverless/serverless",
"serverless/serverless-runtime-babel"

andler.js */
rt "babel-polyfill"
rt request from "request-promise"

t headers = {
ser-Agent': 'Serverless'


rt default ({repos}) => {

turn Promise.all(repos.map(repo => {
let uri = `https://api.github.com/repos/${repo}`

return request({headers, uri, json: true})
  .then(({stargazers_count}) => ({repo, stars: stargazers_count}))
)

Scaffold

You can use serverless function create as usual ? it will promt you for a runtime unless you add the -r babel flag.

Examples

• GitHub stargazers example - Returns amount of starts for a GitHub repo
