The browser session is still privileged: code can +reach any data that is available in that session. Browserbase is the isolation boundary. + +The compatibility runtime is vendored from +`browserbase/stagehand/packages/integrations/core/src/facade/runtime.ts` because the shared +integration core is not a public package export. The source revision is recorded at the top of +`server/stagehand-facade-runtime.ts` so a maintainer can compare and update it. ## Hosted session settings diff --git a/projects/browsie/server/browser-session.ts b/projects/browsie/server/browser-session.ts index 7086af18..6120bf7d 100644 --- a/projects/browsie/server/browser-session.ts +++ b/projects/browsie/server/browser-session.ts @@ -8,10 +8,12 @@ import { type StagehandBrowser, } from "@browserbasehq/stagehand"; +import type { BrowserRefAction, BrowserRunInput } from "../agent/lib/browser-schema.js"; import { parseBrowserbaseCaptchaEvent, safeCaptchaPage, type CaptchaSignal } from "../src/captcha"; import { toEmbeddedBrowserbaseLiveViewUrl } from "../src/live-view.js"; +import { executeStagehandCode } from "./stagehand-run-code.js"; import { addTrace } from "./trace.js"; -import type { BrowserProxyLocation, BrowserState, ConversationState, RunAction } from "./types.js"; +import type { BrowserProxyLocation, BrowserState, ConversationState } from "./types.js"; export interface BrowserCaptchaTransition { id: string; @@ -48,6 +50,8 @@ export class BrowsieBrowserSession { private closeRequested = false; private operationTail: Promise = Promise.resolve(); private xpathMap: Record = {}; + private snapshotUrl?: string; + private snapshotPageId?: string; private readonly visitedOrigins = new Set(); private readonly blockedOrigins = new Set(); private readonly liveSourceOrigins = new Set(); @@ -175,10 +179,13 @@ export class BrowsieBrowserSession { snapshot, url: await page.url(), title: await page.title(), + pageId: page.pageId, }; }); await this.gateCaptcha("after"); this.xpathMap = result.snapshot.xpathMap; + this.snapshotUrl = result.url; + this.snapshotPageId = result.pageId; const url = result.url; this.updateBrowserState(result.url, result.title); await this.refreshRemoteLiveUrl(); @@ -225,73 +232,142 @@ export class BrowsieBrowserSession { } } - async run(actions: RunAction[]): Promise<{ completed: number; url: string }> { + async run( + input: BrowserRunInput, + ): Promise< + | { mode: "code"; value: unknown; url: string } + | { mode: "actions"; completed: number; url: string } + > { const release = await this.acquireOperation(); try { - const localFixture = actions.some( - (item) => - item.action === "goto" && /^http:\/\/(?:127\.0\.0\.1|localhost)(?::|\/)/.test(item.url), - ); + const localFixture = + input.code !== undefined && + /page\.goto\(\s*["'`]http:\/\/(?:127\.0\.0\.1|localhost)(?::|\/)/u.test(input.code); await this.start(localFixture); await this.gateCaptcha("before"); const started = performance.now(); - const resolvedActions = actions.map((item) => - "target" in item && item.target - ? { ...item, target: this.resolveTarget(item.target) } - : item, - ); - const result = await this.requireStagehand().experimentalBatch( - async ({ page }, batchActions) => { - for (const item of batchActions) { - switch (item.action) { - case "goto": - await page.goto(item.url); - await page.waitForLoadState("domcontentloaded", 15_000); - break; - case "click": - await page.locator(item.target).click(); - break; - case "fill": - await page.locator(item.target).fill(item.value); - break; - case "type": - await page.locator(item.target).type(item.value); - break; - case "press": - if (item.target) await page.locator(item.target).click(); - await page.keyPress(item.key); - break; - case "select": - await page.locator(item.target).selectOption(item.value); - break; - case "wait": - await page.waitForTimeout(Math.min(item.milliseconds, 10_000)); - break; + const page = + (await this.browser!.context.activePage()) ??
