AWS serverless(lambda, dynamodb) using serverless framework. Also configured dynamodb and serverless-offline for local development.

Install and run locally

For development, you need to have serverless, npm and/or yarn globally installed. I also prefer using NVM to manage my Node versions. Tested in node v14.

Step1: Install serverless framework CLI

npm install -g serverless

Step2: Configure AWS Setup AWS CLI if you have not already. you can find useful article here create and configure AWS credentials

npm install

setp3: copy .env.example to .env

cp .env.example .env

step4: start local server

# install dynamodb-local
npm run dynamodb:install

If you get the error installing local dynamodb, Please delete package-lock.json and try to install package again. For detail here is recent bug in dunamodb local

# run serverless-offline
npm run start:offline

For lint

npm run lint

Tests: Jest is used for tests Test setupEnv file is located in tests/lib/setupEnv.ts. You can change env variables as your need.

npm run test

Deploy

First, set up your AWS settings and run the following command.

Serverless framework deploy lambda, api gateway, dynamodb and other resources.

npm run deploy:prod

Further improvement

Due to time limitation and i am new to serverless, following things can be improved:

  • use middy.js for request parsing
  • set up AWS alarams for function errors
  • refactor url endpoints to /books => for post and get all, /books/{id} => for delete and update
  • setup CI/CD
