Summary

  • Restore feat(goto): add actions runner with locators and auto-batching #877 after it was dropped in revert: drop actions runner from goto (#877) #884.
  • Add @browserless/goto actions/ runner: toSelector P-selector compiler, unified wait, response buffer for wait request, auto-batching (inject+inject, screenshot+screenshot), timeout clamp.
  • Wire post-adblock: when actions is present, skip legacy click/scroll/wait/inject path; return actionCaptures for mid-flow screenshot/pdf buffers.
  • @browserless/screenshot / @browserless/pdf: when actions include a capture step, skip the redundant final capture and return the last action buffer.

Test plan

  • ava 'test/unit/actions/**/*.js'
  • Confirm goto/screenshot/pdf unit tests still pass
  • Integration: click → wait → screenshot via browserless once API parse lands

Made with Cursor

📝 Walkthrough

Walkthrough

The PR adds browser action sequences with locator support, batching, timeout budgets, wait modes, browser operation handlers, and capture collection. goto, screenshot, and PDF flows now execute configured actions and return action-produced results.

Changes

Browser action sequences

Layer / File(s) Summary
Action locators and batching
packages/goto/src/actions/locator.js, packages/goto/src/actions/batch.js, packages/goto/test/unit/actions/locator.js, packages/goto/test/unit/actions/batch.js
Locator helpers compile action fields into Puppeteer selectors. Batching groups consecutive inject and screenshot actions into parallel waves and keeps barrier actions separate.
Action handlers and wait targets
packages/goto/src/actions/handlers.js, packages/goto/test/unit/actions/handlers.js
Handlers now support injection, clicking, waiting, scrolling, filling, evaluation, screenshots, and PDFs. Timeout clamping and glob conversion are covered by unit tests.
Action wave execution
packages/goto/src/actions/index.js, packages/goto/test/unit/actions/index.js
runActions executes ordered waves under one deadline. It buffers responses, dispatches handlers, collects captures, wraps indexed errors, and removes listeners during cleanup.
Navigation and capture integration
packages/goto/src/index.js, packages/screenshot/src/index.js, packages/pdf/src/index.js
goto accepts actions and an actions timeout. Screenshot and PDF handlers use the corresponding action capture and skip their standard capture path when an action capture exists.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to a0fe5

This PR adds action-driven navigation and changes screenshot/PDF capture behavior, but unresolved issues can silently ignore caller options, return the wrong capture, exceed requested timeouts, and allow pathological request patterns to block the event loop. These correctness, latency, and availability risks make the current head unsafe to merge without fixes or explicit acceptance.

Screenshot batching returns wrong buffer

High Severity

screenshot is treated as parallel-safe and consecutive captures run under Promise.all, but each result is only appended when that capture finishes. @browserless/screenshot then takes actionCaptures.screenshots.at(-1), so the returned image is whichever capture completed last, not the last screenshot action in the list. fullPage captures also mutate the shared viewport, so parallel waves can corrupt each other.

Element screenshot options conflict

Medium Severity

The screenshot action can set both clip and fullPage on the same page.screenshot call, which Puppeteer rejects as exclusive. It also waits for the element without requiring visibility, so a not-yet-visible match yields a null boundingBox and silently captures the viewport instead of the element. Existing waitForElement already waits with visible: true and forces fullPage: false when clipping.

Assert the buffer size, not the listener count.

This test emits 150 responses and then asserts page.listeners.response.length === 1. That assertion checks listener registration. It does not observe MAX_BUFFERED_RESPONSES. The test passes even if the cap in packages/goto/src/actions/index.js is removed.

Assert the bound directly. For example, make the pending wait match the oldest URL and confirm it is no longer served from the buffer, or expose the buffer length through a wait action that matches only the retained window.

Await all wave actions before you propagate the failure.

Promise.all rejects as soon as one action in the wave fails. The sibling actions keep running. runActions then returns through finally, which detaches the response listener while those actions still drive the shared page. The uncompleted actions can mutate the page after the caller handled the error, and they can still push into actionCaptures.

Use Promise.allSettled so the wave settles first, then throw the first rejection.

Bound the wildcard count to prevent catastrophic backtracking.

globToRegExp escapes every literal character, so a user cannot inject regex metacharacters. The wildcard expansion is still unsafe. Each * becomes [\s\S]*, and the 512-character cap allows up to 512 wildcards separated by literals. A pattern such as *a*a*a*… produces nested unbounded quantifiers. On a non-matching URL, the match can backtrack exponentially and block the event loop.

match runs for every buffered response and for every response event during page.waitForResponse, so the cost is paid repeatedly on the request path.

Add a wildcard limit, or collapse consecutive wildcards and use a lazy quantifier.

Clamp the sleep below the wave budget.

When action.timeout is greater than or equal to the remaining budget, clampTimeout returns the budget. setTimeout(budget) then resolves at the same instant that run rejects through pTimeout(fn, budget). The winner is nondeterministic. The action reports either success or actions[i] (wait:timeout) failed: ….

The test runActions shares one deadline across the whole list in packages/goto/test/unit/actions/index.js depends on the sleep winning that race, so it can fail intermittently.

Subtract a small margin so the sleep always settles before the outer timeout.

Record captures by action index, not by completion order.

batchActions in packages/goto/src/actions/batch.js groups consecutive screenshot actions into one wave, and runActions runs a multi-action wave with Promise.all. The handlers then push to actionCaptures.screenshots in completion order. A later action can finish before an earlier one, so array order does not match action order.

Consumers depend on array order. packages/screenshot/src/index.js at Line 289 reads actionCaptures?.screenshots?.at(-1) as the final capture. With a batched wave, that can return the capture of an earlier action.

Store the capture at its index, or sort by index before consumption.

The actions budget is additive to the navigation budget, so goto can exceed the caller timeout.

The budgets are fixed fractions of baseTimeout, not slices of the remaining time:

  • gotoTimeout = baseTimeout * 7/8
  • actionsTimeout = baseTimeout * 1/2

Navigation and actions run in sequence at Line 495 and Line 541. In the worst case they consume baseTimeout * 11/8, plus actionTimeout for inject and waitUntilAuto. baseTimeout is already timeout * 2/3, so a single goto call with actions can run for roughly the whole caller timeout and more, while callers assume baseTimeout bounds the pre-capture work.

Derive the actions budget from the time that remains after navigation.

🐛 Proposed fix to derive the remaining budget
+      const remainingBudget = Math.max(0, baseTimeout - elapsedSinceStart())
       actionCaptures = await runActions(page, actions, {
         inject,
         run,

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Action captures drop the resolved request options in both @browserless/screenshot and @browserless/pdf. The capture handlers in packages/goto/src/actions/handlers.js build page.screenshot and page.pdf options only from the action fields. Both packages now return the action buffer and bypass their own option resolution, so package defaults and caller options are silently ignored.

  • packages/screenshot/src/index.js#L288-L294: forward the resolved opts (type, quality, path, omitBackground) into the screenshot action, or document that action screenshots use Puppeteer defaults and that path is not written.
  • packages/pdf/src/index.js#L176-L188: forward the resolved PDF options (margin, scale, printBackground, format) from PDF_DEFAULT_OPTS and the caller into the pdf action, or document that a pdf action must carry its own complete options.

In `@packages/screenshot/src/index.js` around lines 288 - 294, Update the
action-capture flows so resolved package options are passed into the capture
handlers: in packages/screenshot/src/index.js#L288-L294, forward type, quality,
path, and omitBackground from opts into the screenshot action; in
packages/pdf/src/index.js#L176-L188, forward margin, scale, printBackground, and
format from PDF_DEFAULT_OPTS plus caller-resolved options into the pdf action.
Keep returned buffers as the capture result while ensuring package defaults and
caller options are honored.
