Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Mihai Parparita	7741e9feb0	cmd/tsconnect: add progress and connection callbacks Allows UI to display slightly more fine-grained progress when the SSH connection is being established. Updates tailscale/corp#7186 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	92ad56ddcb	cmd/tsconnect: close the SSH session an unload event instead of beforeunload The window may not end up getting unloaded (if other beforeunload handlers prevent the event), thus we should only close the SSH session if it's truly getting unloaded. Updates tailscale/corp#7304 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Josh Soref	d4811f11a0	all: fix spelling mistakes Signed-off-by: Josh Soref <2119212+jsoref@users.noreply.github.com>	2 years ago
Mihai Parparita	a7a0baf6b9	cmd/tsconnect: add error callback for SSH sessions We were just logging them to the console, which is useful for debugging, but we may want to show them in the UI too. Updates tailscale/corp#6939 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	8158dd2edc	cmd/tsconnect: allow SSH connection timeout to be overridden 5 seconds may not be enough if we're still loading the derp map and connecting to a slow machine. Updates #5693 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	9c6bdae556	cmd/tsconnect: use the parent window for `beforeunload` event listener The SSH session may be rendered in a different window that the one that is executing the script. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	b22b565947	cmd/tsconnect: allow xterm.js terminal options to be passed in Allows clients to use a custom theme and other xterm.js customization options. Fixes #5610 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	c312e0d264	cmd/tsconnect: allow hostname to be specified The auto-generated hostname is nice as a default, but there are cases where the client has a more specific name that it can generate. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	11fcc3a7b0	cmd/tsconnect: fix xterm.js link opening not working when rendered into another window The default WebLinksAddon handler uses window.open(), but that gets blocked by the popup blocker when the event being handled is another window. We instead need to invoke open() on the window that the event was triggered in. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	b302742137	cmd/tsconnect: enable web links addon in the terminal More user friendly, and as a side-effect we handle SSH check mode better, since the URL that's output is now clickable. Fixes #5247 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	01e6565e8a	cmd/tsconnect: temporarily switch to xterm.js fork that handles popup windows Allows other work to be unblocked while xtermjs/xterm.js#4069 is worked through. To enable testing the popup window handling, the standalone app allows opening of SSH sessions in new windows by holding down the alt key while pressing the SSH button.

Mihai Parparita	58f35261d0	cmd/tsconnect: remove debugging code Remove test prefix added to validate the error code from `27f36f77c3`. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	27f36f77c3	cmd/tsconnect: output errors to the JS console too We were just outputting them to the terminal, but that's hard to debug because we immediately tear down the terminal when getting an error. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	7d1357162e	cmd/tsconnect: expose runSSHSession in npm package Move it to lib/ so that it can be used in both the app and the package. Updates #5415 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
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.

Charlotte Brandhorst-Satzkorn	0f12ead567	tsconnect: pass in authkey in dev mode (#5320 ) This change allows for an auth key to be specified as a url query param for use in development mode. If an auth key is specified and valid, it will authorize the client for use immediately. Updates #5144 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	2 years ago
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 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	adc5ffea99	cmd/tsconnect: make PeerAPI work JS -> native nodes worked already, tested by exposing a fetch() method to JS (it's Promise-based to be consistent with the native fetch() API). Native nodes -> JS almost worked, we just needed to set the LocalBackend on the userspace netstack. Fixes #5130 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	9a2171e4ea	cmd/tsconnect: make terminal resizable Makes the terminal container DOM node as large as the window (except for the header) via flexbox. The xterm.js terminal is then sized to fit via xterm-addon-fit. Once we have a computed rows/columns size, and we can tell the SSH session of the computed size. Required introducing an IPNSSHSession type to allow the JS to control the SSH session once opened. That alse allows us to programatically close it, which we do when the user closes the window with the session still active. I initially wanted to open the terminal in a new window instead (so that it could be resizable independently of the main window), but xterm.js does not appear to work well in that mode (possibly because it adds an IntersectionObserver to pause rendering when the window is not visible, and it ends up doing that when the parent window is hidden -- see xtermjs/xterm.js@87dca56dee) Fixes #5150 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	c06758c83b	cmd/tsconnect: allow SSH username to be specified Redoes the UI to be a form, with a username field and a host drop-down. Fixes #5139 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	ab60f28227	cmd/tsconnect: fix xterm CSS not being imported @import rules need to come first, they are (silently) ignored otherwise. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	a3d74c4548	cmd/tsconnect: add basic panic handling The go wasm process exiting is a sign of an unhandled panic. Also add a explicit recover() call in the notify callback, that's where most logic bugs are likely to happen (and they may not be fatal). Also fixes the one panic that was encountered (nill pointer dereference when generating the JS view of the netmap). Fixes #5132 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	617a2ec7cc	cmd/tsconnect: add Tailwind CSS support and switch to using it Integrates Tailwind CSS as an esbuild plugin that invokes the CLI to process the input. It takes ~400ms, so it seems like the easiest option (vs running a separate process for dev mode). Existing minimal look and feel is replicated with Tailwind classes, mostly to prove that the entire system works, including unused class removal. Also fixes yarn warnings about package.json not having a license (which were showing up when invoking any scripts). Fixes #5136 Fixes #5129 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	389629258b	cmd/tsconnect: switch to TypeScript Continues to use esbuild for development mode and building. Also includes a `yarn lint` script that uses tsc to do full type checking. Fixes #5138 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	6f5096fa61	cmd/tsconnect: initial scaffolding for Tailscale Connect browser client 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>	2 years ago
