Mihai Parparita 1a093ef482 cmd/tsconnect: extract NPM package for reusing in other projects
`src/` is broken up into several subdirectories:
- `lib/` and `types`/ for shared code and type definitions (more code
  will be moved here)
- `app/` for the existing Preact-app
- `pkg/` for the new NPM package

A new `build-pkg` esbuild-based command is added to generate the files
for the NPM package. To generate type definitions (something that esbuild
does not do), we set up `dts-bundle-generator`.

Includes additional cleanups to the Wasm type definitions (we switch to
string literals for enums, since exported const enums are hard to use
via packages).

Also allows the control URL to be set a runtime (in addition to the
current build option), so that we don't have to rebuild the package
for dev vs. prod use.

Updates #5415

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.

Library / NPM Package

The client is also available as an NPM package. To build it, run:

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

That places the output in the pkg/ directory, which may then be uploaded to a package registry (or installed from the file path directly).
