waitForContentScript(page: Page): : Promise<void>

Summary

Waits for the content script to finish initializing on the given page. The content script registers chrome.runtime.onMessage synchronously but may call async initContentScript() before being fully operational. We add a small delay after DOMContentLoaded to let that settle. If the page exposes window.__fillAllReady (set by the content script), we wait for that; otherwise we fall back to a 600 ms timeout which is sufficient for document_idle injection.

Source Code

export async function waitForContentScript(page: Page): Promise<void> {
  await page.waitForFunction(
    () =>
      document.readyState === "complete" ||
      document.readyState === "interactive",
  );
  // The content script is injected at `document_idle`; give it time to init.
  await page.waitForTimeout(600);
}

No outgoing dependencies.
