Summary by CodeRabbit

Documentation
- Added a comprehensive blog post on screenshot best practices, covering how to stop real-time regeneration, persist screenshots to storage, map URLs to file identifiers, implement smart refresh strategies (time-based expiration and on-demand), choose optimal formats and sizes, handle dynamic content (including sleep strategies), and general recommendations for building robust screenshot workflows.

_{✏️ Tip: You can customize this high-level summary in your review settings.}

Walkthrough

A new documentation page was added at src/routes/blog/post/screenshots-best-practices/+page.markdoc (~279 added lines). The file contains front-matter and a multipart article covering stopping realtime regeneration, persisting screenshots in storage, URL-to-file-id tracking, refresh strategies (time-based expiration and on-demand), format and size selection, handling dynamic content (sleep), and final guidelines. No executable code, tests, or public/exported API declarations were modified.

+        }
+
+        // Screenshot expired, regenerate and update the row
+        const newFileId = await captureAndStore(url);


This TTL refresh example calls captureAndStore(url), but that helper isn’t defined anywhere in the post. Define it (e.g., as the screenshot capture + Storage upload logic) or replace this call with an existing helper shown earlier.

Suggested change

const newFileId = await captureAndStore(url);

const newFileId = await createScreenshot(url);

+    }
+
+    // No existing screenshot, create new one
+    return await createScreenshot(url);


This function returns createScreenshot(url), but createScreenshot isn’t defined anywhere in the post. Either define it or reuse the earlier screenshot creation logic so the snippet is complete.

Suggested change

return await createScreenshot(url);

const fileId = await captureAndStore(url);

return storage.getFileView('screenshots', fileId);

In `@src/routes/blog/post/screenshots-best-practices/`+page.markdoc:
- Around line 74-79: The snippet uses client but never defines it; add a brief
initialization before using Client/Storage/TablesDB/Avatars (e.g., create and
configure a Client instance and assign it to the variable client) or add a
one-line note that client is assumed to be defined earlier; ensure the symbol
client is present and configured before the lines referencing new
Storage(client), new TablesDB(client), and new Avatars(client) so the snippet
can be copied and run independently.
- Around line 121-153: The example uses undefined helper functions
captureAndStore and createScreenshot in getScreenshot, making the snippet
non-runnable; add brief placeholder implementations or a clarifying note.
Specifically, either add short helper descriptions or minimal implementations
for captureAndStore(url) and createScreenshot(url) (and ensure they return a
fileId or call storage.getFileView as used), or prepend a comment to the
getScreenshot example stating these are stubs/placeholders that must be
implemented (referencing the function name getScreenshot so readers can locate
it). Ensure the helpers' return shapes match the rest of the snippet (fileId or
storage view) so the updateRow and storage.getFileView calls work.

255-264: Add a server-side safety note for auth headers.

The Authorization/Cookie headers example should explicitly state this must be executed server-side (to avoid exposing secrets, and because browsers block setting the Cookie header). A short caution line would prevent misuse.
💡 Suggested addition
+// Run this server-side; do not expose tokens or cookies in client-side code.
 const authenticatedScreenshot = avatars.getScreenshot({

+For pages with heavy JavaScript, 2-3 seconds is usually sufficient. For simple static pages, you can skip the delay entirely.


We should improve that first part and include a mention of loading

Also, pages with heavy JavaScript is a little too informal
