Serverless JWT Auth Boilerplate (⚠️ Work In Progress)

A Serverless REST API boilerplate for authenticating with email/password over JWT (JSON Web Tokens).

In production, it uses:

• AWS Lambda for computing
• AWS Dynamodb for database storage
• AWS Cloudformation to provision the AWS resources
• AWS S3 for object storage (storing the code)

---

Installation

# Install the Serverless CLI
yarn global add serverless

# Clone the repo
git clone https://github.com/mcnamee/serverless-jwt-auth.git serverless-jwt-auth

# Install dependencies
cd serverless-jwt-auth && yarn install

# Add your environment variables (and update the JWT secret)
cp env.example.yml env.prod.yml

---

Usage

Development

You can use Serverless Offline while you develop, which starts a local DynamoDB instance (data is reset on each start)

yarn start

# OR to use env.staging.yml environment variables:
# yarn start --STAGE staging

Tests

yarn test

Production

1. Setup your AWS credentials

Create a new AWS IAM user and assign the AdministratorAccess policy to the new user (later, it's best to reduce the permissions this IAM User has for security reasons).

serverless config credentials --provider aws --key <YOUR_AWS_KEY> --secret <YOUR_AWS_SECRET>

2. Then deploy to AWS

sls deploy

# OR to use env.dev.yml environment variables:
# sls deploy --STAGE dev
