Serverless Node.js Starter

A Serverless starter that adds ES7 syntax, serverless-offline, linting, environment variables, and unit test support. Part of the Serverless Stack guide.

Serverless Node.js Starter uses the serverless-bundle plugin (an extension of the serverless-webpack plugin) and the serverless-offline plugin. It supports:

• Generating optimized Lambda packages with Webpack
• Use ES7 syntax in your handler functions
  • Use import and export
• Run API Gateway locally
  • Use serverless offline start
• 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
• Lint your code with ESLint
• Add environment variables for your stages
• No need to manage Webpack or Babel configs

Demo

A demo version of this service is hosted on AWS - https://z6pv80ao4l.execute-api.us-east-1.amazonaws.com/dev/hello

And here is the ES7 source behind it

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

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

Upgrading from v1.x

We have detailed instructions on how to upgrade your app to the v2.0 of the starter if you were using v1.x before. Read about it here.

Requirements

• Install the Serverless Framework
• Configure your AWS CLI

Installation

To create a new Serverless project.

$ 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

To simulate API Gateway locally using serverless-offline

$ serverless offline start

Deploy your project

$ serverless deploy

Deploy a single function

$ serverless deploy function --function hello

Running Tests

Run your tests using

$ npm test

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

Environment Variables

To add environment variables to your project

1. Rename env.example to .env.
2. Add environment variables for your local stage to .env.
3. Uncomment environment: block in the serverless.yml and reference the environment variable as ${env:MY_ENV_VAR}. Where MY_ENV_VAR is added to your .env file.
4. Make sure to not commit your .env.

Linting

We use ESLint to lint your code via the serverless-bundle plugin.

You can turn this off by adding the following to your serverless.yml.

custom:
  bundle:
    linting: false

To override the default config, add a .eslintrc.json file. To ignore ESLint for specific files, add it to a .eslintignore file.
