Build guide

Environment setup

iTowns uses NPM as the build tool. If you haven't already, install Node.js: https://nodejs.org/

Download dependencies: npm install
Run the dev server:
- npm start (you can change the port: npm start -- --port 3000. If you get an error message that is not related to the port being in use, please update to last lts or stable version)
- Open http://localhost:8080/
- Make changes in the code, the browser will automatically reload on save
Build iTowns to produce a single independent script:
- npm run build
- The script and its source-maps are generated into the dist/ folder
- You can run the built script to verify it works OK:
  - python -m SimpleHTTPServer 8080 (change the port at your convenience)
  - Open http://localhost:8080/
Transpile itowns to ES5 to require it in your code:
- npm run transpile
- The transpiled source is in lib/
- You can then require src/Main.js in your code
Test and lint changes: see test, lint and test-examples npm script
