Summary

Fixes #154

auto-events.js bound a click listener to each link once the page was complete. Links rendered later, by single-page apps or lazy content, were never collected. Now one capturing click listener on the document finds the clicked link and decides at click time what to collect.

Effect on existing installations:

• Event names and metadata: unchanged.
• Newly collected: clicks on links added after the page loaded, clicks before the page finished loading (once the main script has loaded), and clicks that a website's handler stops with stopPropagation on an element inside the link. Websites with such links get more outbound, download, email and phone events.
• Decided at click time: a link's href, title and data-simple-event are read on the click, so links that change after loading are collected the way they are then.
• The capture phase runs before the website's own handlers, so a handler that stops the click doesn't stop collecting it. Before, a handler on an element inside the link could stop it. Navigation and cancelled clicks are left alone, as before.

Size of auto-events.js (minified / gzip -9 / brotli 11): 2590 / 1284 / 1096 bytes before, 2419 / 1210 / 1034 after, so 171 / 74 / 62 bytes smaller.

Merge before docs#79, which no longer tells agents about this limit. It applies from the next release.

Security implications

• No security impact
• Has security impact - described as:

Testing

• pnpm run test:unit: 73 passing.
• pnpm run typecheck, git diff --check and Prettier: clean.
• New unit test: a link added after the script ran, clicked on its child <span>, sends outbound_example_org. A link with data-simple-event only sends its inline event. Against the old build it fails: only the inline event is sent.
• The existing tests now go through the document listener (capture phase) instead of a listener per link.
• The BrowserStack matrix runs in CI.

Walkthrough

Link collection now uses a capturing document listener to find and classify links when clicked. Unit tests cover links added after script load and links with inline events.

Changes: Automated link collection

Layer / File(s)	Summary
Delegated click collection src/auto-events.js, test/unit/auto-events.test.js	collectLink returns a link classification. A capturing document listener finds an anchor from the click target and sends matching events. Tests cover capture-phase registration, updated click fixtures, and clicks on links added after script load.

Full details: Title check

Explanation

The title "Collect automated events for links added after the page loaded" matches the main change. The PR replaces per-link click listeners with one capturing document-level click listener, so links added after load are collected. The title names the primary behavior change and omits the implementation detail, which is acceptable.

Full details: Linked Issues check

Explanation

Issue #154 requires collecting outbound, download, email, and phone link clicks regardless of when the link was added, including clicks before the page finished loading. The reviewed head replaces the DOMContentLoaded scan and per-link listeners in src/auto-events.js with one click listener on the document. The listener is registered in capture phase as soon as the script runs. On each click, it walks from event.target to the nearest A element, then calls collectLink and saAutomatedLink. Because the lookup happens at click time, links added after load are collected. The unchanged collectLink logic still covers download, outbound, email, and phone types. The new unit test in test/unit/auto-events.test.js clicks a late-added link through its child span and expects outbound_example_org. It also confirms that a link with data-simple-event sends only the inline event. No test targets a click made before load. The design covers this case because the listener exists before the page finishes loading. Scope note: saAutomatedLink still requires window[saGlobal] and window[saGlobal + "_loaded"]. A click made before the tracker finishes loading is dropped with a warning. This behavior predates the PR and the issue does not address it.

Full details: Out of Scope Changes check

Explanation

All code changes relate to issue #154. src/auto-events.js removes the readiness check, the DOMContentLoaded scan, and the per-link binding. It adds the delegated capture listener and makes collectLink return its type instead of binding a listener. test/unit/auto-events.test.js adapts the fixture to document-level listeners, makes the tracker tests synchronous, and adds the late-link test. These test changes support the objective. The PR description refers to docs#79, which lies outside this repository, and the PR does not change any file in it. One description claim is inaccurate. It says a handler that stops the click does not stop collection, "just like the per-link listener before". The old per-link listener ran in bubble phase, so a stopPropagation at or below the link prevented collection. The new capture listener runs first, so the claim holds for the new code, but the wording of the comparison is wrong. This is a description issue, not an out-of-scope code change.

Full details: Docstring Coverage

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 2 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

SDLC label: change: needs review because The tracker now also collects clicks on mailto and tel links added after page load, and email and phone collection is on by default, so addresses and numbers rendered dynamically on customer sites are now sent to us where they previously were not src/auto-events.js#L183-L198

On the review summary:

• Description: right, the old per-link listener ran on the link, so a stopPropagation on an element inside the link stopped collection. The description now lists that as newly collected. Before the page finished loading, clicks are collected once the main script has loaded, since saAutomatedLink still waits for sa_event_loaded (unchanged).
• Docstring coverage: skipped. The visitor-facing scripts use short // comments, not docstrings: auto-events.js has none, and the /** ... */ blocks in default.js are build conditions like /** if metadata **/. collectLink and the listener already have comments.
