IWA Bundling Example

A barebones example for bundling an Isolated Web Application

Prep and Bundle

$ git clone https://github.com/michaelwasserman/iwa-bundling-example.git
$ cd iwa-bundling-example
$ openssl genpkey -algorithm Ed25519 -out ed25519key.pem
$ npm install
$ npm run build

This creates iwa-bundling-example.swbn. Download a pre-built copy here. Note: Keep the new ed25519key.pem private key file secure; do not share it in a public repo :)

Run

Run Chrome M124+ and enable flags:

• chrome://flags/#enable-isolated-web-apps
• chrome://flags/#enable-isolated-web-app-dev-mode

$ chrome --enable-features=IsolatedWebApps,IsolatedWebAppDevMode

Visit chrome://web-app-internals/ and point "Install IWA from Signed Web Bundle" to iwa-bundling-example.swbn

Visit chrome://apps and launch "IWA Bundling Example"

Note: If reinstall fails, try restarting Chrome.

Alternative: Self-Host a Dev Mode Proxy

$ git clone https://github.com/michaelwasserman/iwa-bundling-example.git
$ cd iwa-bundling-example/static
$ python3 -m http.server [port]

Visit chrome://web-app-internals/ and point "Install IWA via Dev Mode Proxy" to http://localhost:[port]/
