Introduction

This project is designed to make it easier to develop a new AWS Lambda function.

It provides:

• A minimal and empty project which you can base your new Lambda functions on.
• Dev tools like PHPUnit, PHPStan, CS fixer etc.
• Running your function locally, including Xdebug.
• Bref to run PHP runtime on AWS Lambda.
• Serverless config to easily deploy your function to AWS.
• GitHub Actions workflows to test your code and automatically deploy functions to AWS.

Usage

To set up a new project, just run:

composer create-project leverage-php/lambda-skeleton

If you use Docker:

docker run -it -v $PWD:/app --rm composer create-project leverage-php/lambda-skeleton

It'll create a new folder with a very minimal project and install all dependencies. You also need:

• Copy .env.dist to .env and set up your env values.

• Edit serverless.yml:

#Set up a name of your project. It'll be used in AWS Cloudformation.
service: app

...

functions:
    default:
        #Set up a name for your AWS Lambda function
        name: task-${sls:stage}

That's it.

Development

To invoke your function locally, run:

$ bin/local

# With JSON event data
$ bin/local '{"foo": "bar"}'

# With JSON in a file
$ bin/local --file=event.json

You can use various dev tools thanks to leverage-php/toolchain:

bin/composer - Composer

vendor/bin/test- PHPUnit

vendor/bin/static - PHPStan

vendor/bin/codestyle - PHP CS Fixer

Deployment

To deploy your function, run:

bin/deploy

It'll deploy the project installed on your machine to the dev stage.

Github Actions

There are two predefined workflows to set up Github Actions:

• on-pull-request.yml runs your test tools (PHPUnit, PHPStan and CS fixer) after creating a pull request.

• on-push-main.yml deploys your function to AWS to staging after pushing changes to the main branch.

PHP config

PHP is configured by Bref and contains optimized settings for AWS runtime. In case you need to change them, just create a folder php/conf.d in the root of your project and put your php.ini there.
