Development

Use yarn dev to start the middleware and watcher which runs eslint and the tests on each file change.

Architecture

The middleware is stateless, this enables easy scaling and clustering.

Clustering

The middleware uses the native node clustering module. To enable multiple processes, set a number of processes to spawn in the .env file.

Frameworks

• express.js for HTTP stuff and routing
• Tests are using Mocha and Chai
• Clustering is done with node.js native cluster method
• Logging is done with Winston

Debugging

• Prerequisite: Node v.6.3.0+, Chrome 55+
• Use yarn debug to start the middleware in debugging mode
• When using cluster please take a closer look at the stdout output when starting the server (usally ports 9229, 5859++). Please ensure these ports are also listet in the "Connection" tag
