Development

This uses rollup to build the extension files. Install and run like this:

npm install

# Run this during development
npm start

Extension overview

The extension has four different entry points:

• The content script in src/content.ts runs on the news article page, communicates with background script
• the background script in src/background.ts which opens new tabs, navigates them around and scrapes the content
• the options page in src/options.ts is the options page for the extension
• the popup in popup/ is opened when the extension icon in the toolbar is clicked

These are the relevant players:

• src/providers.ts contains libraries that you authenticate against and that grant access
• src/sources.ts contains databases that you can get access to through providers
• src/sites.ts contains news sites, how to extract their meta data and which source could provide access

For details on how to construct any of these entities, have a look at src/types.ts

Additionally user data like credentials and chosen provider is stored via browser.storage.sync.

Tests

There is a test setup for sites using Jest and Puppeteer that can be run with:

# install dependencies
npm ci
# Run linting and type checking
npm run lint
npm run check-types
# Always run build before tests, as test uses build files!
npm run build
# Run tests
npm run test
# Run tests with actual browser window for one domain
HEADLESS=false npm run test -- -t "test www.zeit.de"

Add testing data to site objects like this:

// ...
  'www.example.com': {
    examples: [
      {
        url: 'http://example.com/article.html',
        selectors: {
          query: 'The string resulting from query selector'
        }
      }
    ],
    // optional setup async function
    testSetup: async (page) => {
        // page is pupeteer page
        // use this for initial page setup
    },
// ...
