Development

During development, the /app folder is being watched for changes.

All changes invoke the TypeScript compiler, which restarts the app upon completion.

npm run watch

Build the Server

To compile the TypeScript code and place into the /dist folder:

npm build

Code Linter

A TypeScript linter has been added to keep code consistent among developers.

npm run lint

To autofix linting errors (not all errors are auto-fixable):

npm run fix

Tests and Coverage

The test coverage percentage should be 90% or greater for any submitted PRs.

For TDD, invoke testing by:
