+# yaak-web
+
+The network half of Yaak in a browser — and, with `--serve`, the half that
+hands the browser the app in the first place.
+
+A tab can't see an HTTP response the way a desktop app can: CORS hides most
+headers (2 of 8 in a typical response), redirects are followed silently, and
+there is no timeline. So the tab renders the request and posts it here, and this
+process puts it on the network with the desktop's own engine (`yaak-http`) and
+streams back everything that happened — every header, every redirect hop, DNS
+timing, the body — for the tab to store.
+
+It is a **stateless executor**. It keeps nothing: no database, no files, no
+sessions, no cookies between calls. Every byte it sees comes from the tab in the
+request, and every byte it returns is stored by the tab. Restart it any time.
+
+## Self-hosting it
+
+One container, no configuration, nothing behind it:
+
+```shell
+docker run -p 8080:8080 ghcr.io/mountain-loop/yaak-web
+```
+
+Open <http://localhost:8080>. The image carries the built web client and this
+binary, which serves it — so the app and its sends are on one origin, and the
+tab's send URL is a path (`/v1/http/send`) rather than an address anyone has to
+configure. The image is `linux/amd64` and `linux/arm64`, built from
+`Dockerfile.web` at the repo root.
+
+Your data lives in your browser (SQLite compiled to wasm, in IndexedDB), not in
+the container. The container is stateless: nothing is written to disk, so
+upgrading is `docker pull` and nothing else.
+
+Two settings are worth knowing about:
+
+```shell
+docker run -p 8080:8080 \
+  -e YAAK_WEB_ALLOW_PRIVATE_NETWORKS=true \
+  -e YAAK_WEB_RATE_LIMIT_PER_MINUTE=0 \
+  ghcr.io/mountain-loop/yaak-web
+```
+
+- **`YAAK_WEB_ALLOW_PRIVATE_NETWORKS=true`** lets sends reach loopback,
+  private and link-local addresses. Off by default, and it should stay off on
+  anything strangers can reach — see [What it refuses](#what-it-refuses-and-why).
+  Turn it on for an instance on your own network, where calling the API on the
+  next machine is the whole point. Note that "private" is relative to the
+  *container*: `127.0.0.1` is the container itself, and reaching the Docker
+  host means `host.docker.internal` (or `--network host`).
+- **`YAAK_WEB_RATE_LIMIT_PER_MINUTE`** defaults to 120 sends per client IP,
+  which suits a public instance and not a team of your own; `0` disables it.
+
+Behind a reverse proxy, add `YAAK_WEB_TRUST_FORWARDED_FOR=true` so the rate
+limit sees real client addresses instead of its own — and only then, since
+otherwise anyone can spoof the header. If the reverse proxy buffers responses,
+tell it not to: sends are streamed, and the `X-Accel-Buffering: no` header this
+binary sets is honoured by nginx-shaped ones.
+
+## Running it from source
+
+```shell
+cargo run -p yaak-web -- --serve dist/apps/yaak-client
+```
+
+after a `YAAK_TARGET=web SKIP_WASM_BUILD=1 npx vp -C apps/yaak-client build`.
+Without `--serve` it is the send executor alone, which is what the frontend
+dev server wants:
+
+```shell
+cargo run -p yaak-web
+YAAK_TARGET=web npm run dev --workspace @yaakapp/yaak-client
+```
+
+A dev build looks for the server at `http://127.0.0.1:9227` (the Vite server is a
+different origin and serves no `/v1`); a production build sends to its own
+origin unless `VITE_YAAK_WEB_URL` was set when it was built.
+
+## Configuration
+
+Every flag has a `YAAK_WEB_*` environment variable, so a container needs no
+arguments; `--help` lists them all.
+
+| Flag | Default | What |
+| --- | --- | --- |
+| `--serve` | off | Also serve a built web client from this directory, on the same origin. |
+| `--bind` | `127.0.0.1:9227` | Listen address. The image sets `0.0.0.0:8080`. |
+| `--allow-private-networks` | off | Allow sends to loopback, private and link-local addresses. |
+| `--allowed-origins` | `*` | CORS origins, comma-separated. Unused when the app is served from here: same origin, no CORS. |
+| `--max-request-bytes` | 16 MiB | Largest rendered request accepted from the tab. |
+| `--max-response-bytes` | 64 MiB | Largest upstream body relayed before the send is cut off. |
+| `--max-timeout-secs` | 60 | Ceiling on a send's timeout; a request asking for more (or none) gets this. |
+| `--rate-limit-per-minute` | 120 | Sends per client IP per minute; 0 disables. |
+| `--max-concurrent` | 256 | Sends in flight at once. |
+| `--trust-forwarded-for` | off | Take the client IP from `X-Forwarded-For`. Only behind a load balancer that sets it. |
+
+## Serving the app
+
+`--serve DIR` puts a file server behind the API routes: `/v1/*` is matched
+first, everything else comes from `DIR`, and a path with no file behind it gets
+`index.html` so the app's own routes survive a refresh. Responses are compressed
+(gzip or zstd) on the fly. `/assets/*` is cached forever — Vite content-hashes
+those names — and everything else is `no-cache`, so a new deploy arrives on the
+next reload.
+
+Serving files changes nothing about sending: the same rendered request, the same
+destination policy, the same stateless executor. It exists so that a
+self-hosted Yaak is one thing to run rather than two.
+
+## Split deployments
+
+The app and the sender can still be separate services — one CDN-hosted bundle and
+one server elsewhere, or one server shared by several fronts. Then the bundle has
+to be told where to send, at build time:
+
+```shell
+docker build -f Dockerfile.web \
+  --build-arg VITE_YAAK_WEB_URL=https://send.example.com .
+```
+
+and the server needs the CORS origins its callers use, since the requests are no
+longer same-origin:
+
+```shell
+docker run -p 8080:8080 \

+```
+
+The trailing `yaak-web` is a command override: the same image run without
+`--serve`, so it executes sends and serves no app.
+
+## What it refuses, and why
+
+A hosted sender is, by construction, a machine that makes HTTP requests on
+behalf of strangers. Left alone that is an open relay into whatever network it
+sits on. So by default it refuses to connect to:
+
+- loopback (`127/8`, `::1`), private (`10/8`, `172.16/12`, `192.168/16`,
+  `fc00::/7`), link-local (`169.254/16` — where cloud metadata lives — and
+  `fe80::/10`), carrier-grade NAT, multicast, reserved and unspecified ranges,
+  IPv4 addresses carried inside IPv6 forms (`::ffff:a.b.c.d`, the well-known
+  NAT64 prefix, 6to4), and the whole NAT64 local-use range;
+- anything not `http://` or `https://`.
+
+The check runs **on the resolved addresses, after DNS**, for every hop of a
+redirect chain, so a public hostname that points at an internal address is
+caught, and so is a `Location:` header that points at one. It also refuses body
+types that would read files on its own disk (`binary`, multipart file
+fields), since no browser tab could legitimately mean those.
+
+Refusals are logged with the reason. On a public instance (`web.yaak.app`, or
+anything else strangers can reach) this must stay on: the machine's private
+network is the host's, not the user's, so a `localhost` or LAN API is not the
+user's to reach through it — the desktop app is what reaches those. On an
+instance you run for yourself, that reasoning is inverted, and
+`--allow-private-networks` inverts the policy with it. It allows every range
+above, including `169.254.169.254`, so use it only where the network on the
+other side is one the users are entitled to.
+
+There is no authentication either way: an instance is anonymous, protected by
+the per-client rate limit and the destination policy. Anything more (a shared
+token, per-user quotas) is a later slice and would sit in front of `send_http`
+in `main.rs`. Put TLS in front of a public instance.
+
+## The wire
+
+`POST /v1/http/send` with a JSON body:
+
+```json
+{
+  "request":  { "url": "https://…", "method": "GET", "headers": […], "body": {…}, "bodyType": null, "urlParameters": […] },
+  "settings": { "validateCertificates": true, "followRedirects": true, "timeoutMs": 0, "sendCookies": true, "storeCookies": true },
+  "cookies":  [ … ] 
+}
+```
+
+`request` is a Yaak `HttpRequest` in the desktop's own model shape with every
+template already rendered by the tab; the server builds the URL, headers and
+body from it exactly the way the desktop does after rendering. `cookies` is the
+jar's contents (or `null` for no jar).
+
+The reply is `application/x-ndjson`, one JSON frame per line, in the order things
+happened:
+
+| `type` | When | Carries |
+| --- | --- | --- |
+| `event` | as the engine produces them | one timeline event, in the desktop's `http_response_event.event` shape |
+| `response` | once, when the final hop's headers arrive | status, all headers, request headers as sent, remote address, HTTP version, timing |
+| `body` | as the body is read | a decompressed chunk, base64 |
+| `done` | last, on success | elapsed, byte counts, and the cookie jar as the send left it |
+| `error` | last, on failure | the reason, and any cookies collected before the failure |
+
+Refusals that happen before anything is sent (a blocked destination, a bad body,
+rate limit, capacity) are plain HTTP errors (`403`, `400`, `429`, `503`) with
+`{"error": "…"}`, not streams.
+
+Why a streamed HTTP response and not a WebSocket: one `POST` is stateless by
+construction, cancellable by closing the connection, readable with `curl`, and
+needs no upgrade handling on either side. A WebSocket only earns its keep when
+traffic is bidirectional, which a single send is not.
+
+The TypeScript side of this contract is generated from `src/wire.rs` by ts-rs
+into `bindings/` (run `cargo test -p yaak-web` after changing a frame)
+and published to the tab as `@yaakapp-internal/web`, so a change to the
+wire on one side is a type error on the other.
+
+`GET /v1/health` reports the version and the effective limits.
+
+## What comes later
+
+Not built, by design, but the router is shaped for it: a WebSocket relay
+(`/v1/ws/relay`) and a gRPC relay (`/v1/grpc/relay`) would be long-lived,
+bidirectional endpoints on the same binary, behind the same destination policy
+and limits. They differ from this endpoint in holding per-connection
+in-memory state while a connection is open (never persisted), which brings
+connection limits and a larger abuse surface — the reason they are separate
+work.

Gregory Schier	115615d994	Let the web image workflow publish a version by hand `latest` could only ever come from a release tag, and tagging also fires the app and CLI releases. A dispatch that names a version now publishes it and latest, which is how the first image gets out before a release exists.	2026-08-18 11:48:59 -07:00

Gregory Schier	33f32cccf6	Leave browser zoom to the browser (#578 ) The web build bound Cmd/Ctrl +, - and 0 and then did nothing with them, so zoom appeared broken. Those keys are the browser's own page zoom, which scales the whole page and remembers it per site. Adds an interfaceZoom capability: true on desktop, where the host zooms the webview, false in a browser. When false the app binds nothing and the hotkeys screen drops the three rows it can't configure.	2026-08-17 11:29:20 -07:00

Gregory Schier	2d2a390bfd	Use clang-18 from apt.llvm.org for the wasm build on 22.04 runners clang-15 got past the C23 [[noreturn]] error but still fails compiling sqlite-wasm-rs for wasm32: its stdint.h falls through to host glibc headers (bits/libc-header-start.h not found). clang-18 handles wasm32 as freestanding and compiles it (it is what ubuntu-24.04 uses). 22.04's repos stop at clang-15, so install 18 from apt.llvm.org. Runners stay on 22.04 to keep the glibc floor.	2026-08-16 22:54:34 -07:00
