Now that we know how to set our Serverless projects up, it makes sense that we have a good starting point for our future projects. For this we created a couple of Serverless starter projects that you can use called, Serverless Node.js Starter. We also have a Python version called Serverless Python Starter. Our starter projects also work really well with Seed; a fully-configured CI/CD pipeline for Serverless Framework.

Serverless Node.js Starter uses the serverless-webpack plugin, Babel, and Jest. It supports:

  • Use async/await in your handler functions
  • Support for unit tests
    • Run npm test to run your tests
  • Sourcemaps for proper error messages
    • Error message show the correct line numbers
    • Works in production with CloudWatch
  • Automatic support for multiple handler files
    • No need to add a new entry to your webpack.config.js

Demo

A demo version of this service is hosted on AWS - https://cvps1pt354.execute-api.us-east-1.amazonaws.com/dev/hello.

And here is the ES7 source behind it.

export const hello = async (event, context, callback) => {
  const response = {
    statusCode: 200,
    body: JSON.stringify({
      message: `Go Serverless v1.0! ${(await message({ time: 1, copy: 'Your function executed successfully!'}))}`,
      input: event,
    }),
  };

  callback(null, response);
};

const message = ({ time, ...rest }) => new Promise((resolve, reject) => 
  setTimeout(() => {
    resolve(`${rest.copy} (with a delay)`);
  }, time * 1000)
);

Requirements

Installation

To create a new Serverless project with ES7 support.

$ serverless install --url https://github.com/AnomalyInnovations/serverless-nodejs-starter --name my-project

Enter the new directory.

$ cd my-project

Install the Node.js packages.

$ npm install

Usage

To run a function on your local

$ serverless invoke local --function hello

Run your tests

$ npm test

We use Jest to run our tests. You can read more about setting up your tests here.

Deploy your project

$ serverless deploy

Deploy a single function

$ serverless deploy function --function hello
