- Java Runtime Engine (JRE) version 6.x or newer to run dynamodb locally.
- Support serverless v1.26.0
- Support offline development with dynamodb, lambda and API Gateway
- Support local dynamodb seeds/migrations
- Build automation in client and server to ease local development
- Deploy to multiple API Services
- Use of Environment variables
- Lambda CRUD operations for a Todo application with live reload
- React web application to utilize the API
We have used serverless-offline plugin and serverless-dynamodb-local plugin in this boilerplate. You can declare your table templates and seeds in api/todo/offline/migrations/ folder just like the todo.json template. When you spin up the offline server, these tables will be used as the datasources for your lambda functions.
Thanks to the offline plugin's environment variable IS_OFFLINE we can select between local dynamodb and aws dynamodb.
var dynamodbOfflineOptions = {
region: "localhost",
endpoint: "http://localhost:8000"
},
isOffline = () => process.env.IS_OFFLINE;
var client = isOffline() ? new AWS.DynamoDB.DocumentClient(dynamodbOfflineOptions) : new AWS.DynamoDB.DocumentClient();

- Clone this repo.
- Make sure AWS credentials are setup properly. Otherwise refer this document
aws configure --profile peter
- Add the aws cli profile name and region on to serverless.yml file located at /api/todo/serverless.yml
...
provider:
name: aws
runtime: nodejs6.10
profile: peter
stage: dev
region: eu-west-2
...
- Install serverless globally
npm i -g serverless
- Install project dependencies.
cd serverless-react-boilerplateand type,
npm install
- Install dynamodb local. (Make sure you have Java runtime 6.x or newer)
npm run db-setup
- Run the app with the local server
npm run app
- Browser will open the todo app at
http://localhost:3001
When you are ready to deploy your database and api to AWS, you can create multiple APIGateways for different service level stages. For example you can create "dev" and "production" stages. When you deploy to a specific stage, it will create a separate database tables for that stage.
Following command will deploy your lambda functions and APIGateway onto 'prod' stage.
cd api
cd todo
serverless deploy --stage prod
If you want to test your React app with the online API and Database, you may have to change the, BASE_URL of the react app found in web/src/App.js. Change its value from http://localhost:3000 to your APIGateway uri.
You can define application secret keys in config.yml file. For example if you need to have a database connection string and use it in your lambda function, define it as follows.
prod:
DB_STRING: <my-db-connection-string>
Then in the serverless.yml file,
custom:
DB_STRING: ${file(./config.yml):${self:custom.stage}.DB_STRING}
This will corretly select the DB_STRING corresponding to the defined stage.
You should NOT commit config.yml to your version control system
Once you have setup a S3 bucket with static web hosting enabled you can simply build your react app and deploy to that bucket. Make sure to change BASE_URL to refer your production APIGateway endpoint.
On the root level package.json file add that bucket name and your AWS profile name on the deploy-s3 task. After that run the following command.
npm run deploy-s3
See following vidoes for a step by step guide to create a s3 bucket and configure static web hosting.
