Ready to use Node.js microservice

Features

• Framework: Express
• Authentication: JWT with public/private key file
• Database: MongoDB (Native), PostgreSQL (Sequelize)
• Code: ESLint, Prettier, Husky
• Debuging: Debug, VS Code configurations
• Logging: Winston
• Testing: Jest, SuperTest, AutoCannon
• Continuous Integration: GitHub Actions + Docker Compose
• Other: PM2, DotEnv
• Well structured
• API versioning
• Request Validation

Getting Started

git clone https://github.com/sonufrienko/microservice
cd microservice

# Create environment variables from example
mv .env.example .env

# Generate JWT keys
ssh-keygen -t rsa -b 2048 -q -N '' -m PEM -f private.key \
&& rm private.key.pub \
&& openssl rsa -in private.key -pubout -outform PEM -out public.key

# Install all dependencies
npm install

# Run on port 4000
npm start

Running SQL database migrations

npx sequelize db:migrate

Start with PM2

pm2 start process.json

Start with Docker

# Generate JWT keys
ssh-keygen -t rsa -b 2048 -q -N '' -m PEM -f private.key \
&& rm private.key.pub \
&& openssl rsa -in private.key -pubout -outform PEM -out public.key

# Build image
docker build -t app/microservice:v1 .

# Run on port 4000
docker run -p 4000:4000 -d --name microservice app/microservice:v1

# Run on host network
docker run -d --name microservice --network=host app/microservice:v1
