This repository used angular.io quickstart as a starting point.

This is not not designed for production use, but a test app that focuses on showing you how the reference image recognition and processing backend may be used

Node.js and npm are essential to Angular development.

Verify that you are running at least node v4.x.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors.

We recommend nvm for managing multiple versions of node and npm.

See npm and nvm version notes above

Install the npm packages described in the package.json and verify that it works:

npm install
npm start

The npm start command first compiles the application, then simultaneously re-compiles and runs the lite-server. Both the compiler and the server watch for file changes.

Shut it down manually with Ctrl-C.

Here are the useful commands in npm scripts defined in the package.json:

• npm start - runs the compiler and a server at the same time, both in "watch mode".
• npm run tsc - runs the TypeScript compiler once.
• npm run tsc:w - runs the TypeScript compiler in watch mode; the process keeps running, awaiting changes to TypeScript files and re-compiling when it sees them.
• npm run lite - runs the lite-server, a light-weight, static file server, written and maintained by John Papa and Christopher Martin with excellent support for Angular apps that use routing.
