README

This is an example of a typescript app that is compiled down to a single js file for consumption in a browser.

Technologies used

• typescript
• karma
• jasmine
• rollup (for bundling)

How to use

npm install // installs

npm run build // bundles

Output will be created in dist/bundle.js

Load test/index.html in browser.

All exported classes are available under the namespace specified in rollup.config.js -> output.name value (MyNamespace here)

Unit testing

Prerequisit

Chrome installed on machine

Running

./node_modules/karma/bin/karma start

Runs tests without debugging. Uses ChromeHeadless (ie, no browser will open).

Debugging

Step 1 ./node_modules/karma/bin/karma start --no-single-run --browser=Chrome

Step 2 Click "Debug" button

Step 3 Inspect page, go to sources, open up base/src and find ts files of interest (greeter.spec.ts and greeter.ts).

Step 4 Set breakpoints in browser and refresh page

Helpful Hints

May wish to install karma and karma-cli globally:

npm install karma karma-cli -g

Then you can run using: karma start
