A convention based API Gateway that will handle incoming HTTP traffic, transform to bus message and publish on NATS bus.
Install dependencies:
npm install
Start server:
npm start
During development nodemon is handy, it will watch and restart server when files changes:
# If you haven't already installed, do it:
npm install nodemon -g
# Start watch - any change to the project will now restart the server, or typ `rs` to trigger restart manually.
nodemon ./app.js
Configuration is set with environment variables. All config defaults to values that makes sense for development.
