Add drive.go (build tag !ts_omit_drive): implements drive.FileSystemForRemote with a JS-backed handler. Streams request bodies chunk-by-chunk via readBodyChunk() and response bodies via write()/end() callbacks so no full-body buffering occurs regardless of file size. The handler is nil-safe: returns 404 until setDriveHandler() is called from JS. Add drive_stub.go (build tag ts_omit_drive): no-op stubs for stripped builds. Add peer.go: extract buildPeerAPIURL helper (previously inline in run()). Modify wasm_js.go: call initDriveForRemote before NewLocalBackend (SubSystem is set-once), expose setDriveHandler and listDrivePeers via wireDriveJS, and refactor the inline peerAPI URL logic to use buildPeerAPIURL. listDrivePeers mirrors native driveRemotesFromPeers: returns empty if DriveAccessEnabled() is false, then filters peers by PeerCapabilityTaildriveSharer using lb.PeerCaps(addr).HasCapability() (the live ACL-derived cap map).

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, CSS and Go wasm package changes can be picked up with a browser reload. Server-side Go changes require the server to be stopped and restarted. In development mode the state the Tailscale client state 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).
To do two-sided development (on both the NPM package and code that uses it), run:
./tool/go run ./cmd/tsconnect dev-pkg
This serves the module at http://localhost:9090/pkg/pkg.js and the generated wasm file at http://localhost:9090/pkg/main.wasm. The two files can be used as drop-in replacements for normal imports of the NPM module.
