Prerequisites

• Docker
• Node.js

Getting Started

• Run git clone https://github.com/ngneat/nx-serverless.git your-app-name
• Run npm install
• Run npm run localstack ( Check that it works by going to http://localhost:4566/health)
• Run npx nx deploy core --stage local to create the table
• Update the environment files based on your configuration
• Run npm run serve

About the App

The application contains three services:

Auth Service:

The auth service is responsible for authentication. It exposes one route for signing up:

curl --request POST 'http://localhost:3001/dev/auth/sign-up' \
--data-raw '{
    "email": "netanel@gmail.com",
    "name": "Netanel Basal"
}'

The request returns a JWT, which is used for accessing protected routes.

Users Service:

The users service is responsible for managing users. It exposes one route:

curl 'http://localhost:3003/dev/user' --header 'Authorization: token TOKEN'

The request returns the logged-in user.

Todos Service:

The todos service is responsible for managing todos. A user has many todos. It exposes CRUD routes:

// Get user todos
curl 'http://localhost:3005/dev/todos' --header 'Authorization: token TOKEN'

// Get a single todo
curl 'http://localhost:3005/dev/todos/:id' --header 'Authorization: token TOKEN'

// Create a todo
curl --request POST 'http://localhost:3005/dev/todos' \
--header 'Authorization: token TOKEN'
--data-raw '{
    "title": "Learn Serverless"
}'

// Update a todo
curl  --request PUT 'http://localhost:3005/dev/todos/:id' \
--header 'Authorization: token TOKEN' \
--data-raw '{
    "completed": true
}'

DynamoDB GUI

Download NoSQL Workbench for DynamoDB and connect to http://localhost:4566.

Commands

nx serve <service-name>
nx deploy <service-name>
nx remove <service-name>
nx build <service-name>
nx lint <service-name>
nx test <service-name>

// Use different enviroment
NODE_ENV=prod nx deploy <service-name> 
NODE_ENV=stg nx deploy <service-name> 

// Run only affected
nx affected:test
nx affected:deploy

Generators

// Generate a service
yarn g:service tags

// Generate handler
yarn g:handler handler-name

// Generate http handler
yarn g:http-handler create-tag

// Generate a model
yarn g:model tag

CI/CD Pipeline with Github Actions

The pipeline has been configured to run everytime a push/pull_request is made to the main branch. You should uncomment the ci.yml workflow.

Workflow Steps

• Checkout: The checkout action is used to checkout the source code.

• Node setup: The setup-node action is used to optionally download and cache distribution of the requested Node.js version.

• lint and test: The lint and test runs only on affected projects.

• Configure AWS credentials: The credentials needed are AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY and should be set as Github secrets.

• Each branch should be prefixed with the environment name. For example, if we have a stg-feature-name branch and open a pull request to the main branch, it will set NODE_ENV to stg and deploy to this environment.

By merging the pull request to the main branch, NODE_ENV is set to prod, and the deployment is done to production.

The workflow file can have as many environments as you need.
