Mihai Parparita ab159f748b cmd/tsconnect: switch UI to Preact
Reduces the amount of boilerplate to render the UI and makes it easier to
respond to state changes (e.g. machine getting authorized, netmap changing,
etc.)

Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible
size contribution. We mitigate the delay in rendering the UI by having a static
placeholder in the HTML.

Required bumping the esbuild version to pick up evanw/esbuild#2349, which
makes it easier to support Preact's JSX code generation.

Fixes #5137
Fixes #5273

tsconnect

The tsconnect command builds and serves the static site that is generated for the Tailscale Connect JS/WASM client.

Development

To start the development server:

./tool/go run ./cmd/tsconnect dev

The site is served at http://localhost:9090/. JavaScript and CSS changes can be picked up with a browser reload. Go changes (including to the wasm package) require the server to be stopped and restarted. In development mode the state the Tailscale client is stored in sessionStorage and will thus survive page reloads (but not the tab being closed).

Deployment

To build the static assets necessary for serving, run:

./tool/go run ./cmd/tsconnect build

To serve them, run:

./tool/go run ./cmd/tsconnect serve

By default the build output is placed in the dist/ directory and embedded in the binary, but this can be controlled by the -distdir flag. The -addr flag controls the interface and port that the serve listens on.
