The tests run straight from the TypeScript +sources through Node's own type stripping, so `npm test` works with nothing +installed at all. + +```bash +cd sdk/node +npm install # only needed for `npm run build` +npm run build +``` + +The convenience helper is `withProfile(profileId, options, work)`, a callback +rather than `await using`. `await using` is not yet syntax any released V8 +understands, so TypeScript has to down-level it — which would stop the sources +running under Node's type stripping, and with it `npm test` on a clean +checkout. The callback form works on every Node 22. A `RunSession` does also +implement `Symbol.asyncDispose`, so `await using` is there for anyone whose +toolchain already handles it. + +```ts +import { Conflict, DonutClient, NotFound, RateLimited } from "@donutbrowser/sdk"; + +const PROFILE_ID = "your-profile-id"; +const client = new DonutClient({ token: "..." }); + +// The browser starts before `work` runs and is stopped after it, even when it +// throws. `session.cdpUrl` is the DevTools endpoint the launch returned. +const titles = await client.withProfile( + PROFILE_ID, + { url: "https://example.com", headless: true }, + async (session) => { + console.log("CDP:", session.cdpUrl); + + const page = await client.agentPerceive(PROFILE_ID, { viewport_only: true }); + console.log(page.stats.returnedNodes, "nodes,", page.text.length, "characters"); + + const search = { role: "textbox", nameContains: "Search" }; + const resolved = await client.agentResolveLocator(PROFILE_ID, { locator: search }); + if (resolved.matchCount !== 1) { + throw new Error("the search box is ambiguous"); + } + + await client.agentType(PROFILE_ID, { locator: search, text: "donut browser" }); + await client.agentClick(PROFILE_ID, { + locator: { role: "button", name: "Search" }, + }); + + const extraction = await client.agentExtract(PROFILE_ID, { + container: { role: "listitem" }, + field_map: [ + { key: "title", locator: { role: "heading" }, source: "text" }, + { key: "link", locator: { role: "link" }, source: "link" }, + ], + max_pages: 3, + }); + return extraction.rows.map((row) => row.values.title); + }, +); +// The browser is stopped here. + +try { + await client.runProfile(PROFILE_ID); +} catch (error) { + if (error instanceof Conflict) { + console.log("someone else has it:", error.code); + } else if (error instanceof RateLimited) { + console.log("wait", error.retryAfter, "seconds"); + } else if (error instanceof NotFound) { + console.log("no such profile"); + } else { + throw error; + } +} +``` + +### Tests + +```bash +cd sdk/node +npm test +``` + +`npm test` runs the TypeScript sources directly, which needs Node 22.18 or +newer (type stripping is unflagged from that release). The published package +ships compiled `.mjs`, so consumers only need Node 22. + +## Errors + +Both packages map the app's documented statuses onto the same set of classes. +The 5xx classes share one base, so a single `ServerError` branch catches every +server-side failure. + +| Status | Python | Node | Meaning | +| ---: | --- | --- | --- | +| 400 | `ValidationError` | `ValidationError` | Malformed request, duplicate name, unsupported input | +| 401 | `Unauthorized` | `Unauthorized` | Missing or wrong bearer token | +| 402 | `PaymentRequired` | `PaymentRequired` | Automation needs an active paid plan | +| 403 | `Forbidden` | `Forbidden` | Wayfern terms not accepted, or not signed in | +| 404 | `NotFound` | `NotFound` | No entity with that id | +| 408 | `RequestTimeout` | `RequestTimeout` | `agent/pick` waited and nothing was picked | +| 409 | `Conflict` | `Conflict` | A browser, a teammate or a remote session holds the profile | +| 429 | `RateLimited` | `RateLimited` | Automation quota spent; `retry_after` / `retryAfter` | +| 500 | `ServerError` | `ServerError` | Internal failure | +| 502 | `BadGateway` | `BadGateway` | The browser or the relay answered wrongly | +| 503 | `ServiceUnavailable` | `ServiceUnavailable` | Cloud, fleet or lock service unreachable | + +Anything else becomes `DonutAPIError` / `DonutApiError` (a `ServerError` for an +unrecognised 5xx), so a status added to the app later still arrives as +something a caller can catch. A transport failure — the app not running, the +API switched off, the wrong port — is `DonutConnectionError`, never an API +error, so "Donut is not there" is never confused with "Donut said no". + +Every error carries `status`, `body`, `method` and `path`. When the body is one +of the app's structured `{"code": ..., "params": {...}}` strings, `code` and +`params` are filled in too. + +A `503` from stopping something means the fleet could not be reached and the +remote browser is **still running**, not that it stopped. + +## Staying in step with the app + +`api-paths.json` in this directory lists every operation the app publishes. It +is generated from the `#[utoipa::path]` annotations and the `ApiDoc` `paths(...)` +list in `src-tauri/src/api_server.rs` — the two things the served +`/openapi.json` is actually built from — and the generator fails if a handler is +annotated but missing from `ApiDoc`, which is exactly how an endpoint silently +disappears from the spec. + +```bash +python3 sdk/tools/extract-api-paths.py +``` + +Each SDK keeps its own table of operation to method (`donutbrowser.coverage` and +`OPERATIONS` in the Node package), and both test suites hold that table against +the snapshot in **both** directions: + +- an operation in the snapshot that the SDK neither wraps nor lists as omitted + fails the suite, so a new endpoint cannot slip past unnoticed; +- an entry the app no longer publishes fails too, so a removed endpoint cannot + linger as a dead method; +- every wrapped operation must name a method that really exists, no two + operations may claim the same method, and every omission must carry a reason. + +On top of that, one parameterised test per method drives it against a fake +server and asserts the exact verb, path, query string and JSON body it sends. +That is what ties the table to reality rather than to a comment. + +Of the 71 published operations, 70 are wrapped. The one omission: + +- `GET /v1/remote-sessions/{id}/cdp` is a WebSocket upgrade, not a request an + HTTP client can make, and bundling a websocket implementation would end the + zero-dependency promise for one endpoint. `remote_session_cdp_url()` / + `remoteSessionCdpUrl()` builds the `ws://` address instead, so a websocket + library of your choosing can connect — send the same `Authorization: Bearer` + header on the handshake. + +## Tests + +Both suites run offline against a fake HTTP server on an ephemeral loopback +port. Neither needs the desktop app, a browser, a network, or credentials. diff --git a/sdk/api-paths.json b/sdk/api-paths.json new file mode 100644 index 0000000..b684e38 --- /dev/null +++ b/sdk/api-paths.json @@ -0,0 +1,363 @@ +{ + "source": "src-tauri/src/api_server.rs", + "regenerate_with": "python3 sdk/tools/extract-api-paths.py", + "description": "Every operation the desktop app publishes in its /openapi.json.

The remote-control bridge: one outbound socket that lets Donut cloud drive +//! this installation's MCP tools. +//! +//! The local MCP server in [`crate::mcp_server`] answers on loopback, which is +//! only reachable by an agent running on this machine. Remote control inverts +//! the reach without inverting the trust: nothing dials in to the desktop.
