Runs a Tailscale client in the browser (via a WebAssembly build of the wasm package) and allows SSH access to machines. The wasm package exports a newIPN function, which returns a simple JS object with methods like start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh package is used for the SSH client. Terminal emulation and QR code renedring is done via NPM packages (xterm and qrcode respectively), thus we also need a JS toolchain that can install and bundle them. Yarn is used for installation, and esbuild handles loading them and bundling for production serving. Updates #3157 Signed-off-by: Mihai Parparita <mihai@tailscale.com>

tsconnect implements development/build/serving workflows for Tailscale Connect.
|
|
It can be invoked with one of three subcommands:
|
|
|
|
- dev: Run in development mode, allowing JS and CSS changes to be picked up without a rebuilt or restart.
|
|
- build: Run in production build mode (generating static assets)
|
|
- serve: Run in production serve mode (serving static assets)
|
|
`[1:])
|
|
os.Exit(2)
|
|
}
