# Clone repository
git clone git@github.com:codingandfitness/LambdaStarter.js.git --depth=1
# Go to graphql-starter folder
cd LambdaStarter
# Install dependencies
npm i
# Start DynamoDB in any network you want
docker run -d -p 8000:8000 --network lambdastarter_default --name dynamodb amazon/dynamodb-local
# Create the table Book in DynamoDB
aws dynamodb create-table --table-name Book --attribute-definitions AttributeName=pkey,AttributeType=S AttributeName=skey,AttributeType=S --key-schema AttributeName=pkey,KeyType=HASH AttributeName=skey,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5 --endpoint-url http://localhost:8000
# Execute de Lambda "CreateBook" in the specific network
sam local invoke "CreateBook" --docker-network lambdastarter_default
# If you want to simulate an incoming data event
sam local invoke "CreateBook" --debug-port 5858 --docker-network lambdastarter_default -e src/book/book.event.json
# Start the project with hotreload
npm run watch
# Deploy lambda to AWS
sam deploy
# DynamoDB list of local Tables
aws dynamodb list-tables --endpoint-url http://localhost:8000
# Scan items in specific Table
aws dynamodb scan --table-name Book --endpoint-url http://localhost:8000
To ensure our work, we use Visual Studio Code and a few addons that will make our work much cleaner and professional.
To install the add-ons necessary to work faster and cleaner we must go to the extension icon on the left panel and search all the add-on and installed.
