How to debug a publish or optimization warning
This guide covers two site publishing errors—publishing and optimization errors—and their resolution strategies.
Publishing errors
If a publishing error occurs, you’ll see a toast notification:
“Failed to publish because there is an error on a page.”
A Review button will also be provided.
Common causes of publishing errors
Dynamic runtime errors:
The site compiler timed out while waiting for a component to build.
Example error in the web inspector:
ensureComponentsInLoader: Component loader not updated in time.Solution: Retry publishing. If the issue persists, fix or remove the problematic component.
Missing used components:
A component might no longer be available due to a file rename, function rename, or a loading error.
Clicking the Review button will highlight the missing component as a grey error placeholder in the layer panel.
Solution: Fix or replace the missing component.
What is optimization?
Framer sites are built using React. Optimization “pre-renders” your site on the server, ensuring visitors see content immediately instead of a blank page while React loads in the background.
Why addressing these warnings matters
Fixing optimization warnings in a Framer project is essential to ensure your website performs well, loads quickly, and ranks higher in search engine results.
Script optimization: Framer bundles, chunks, and tree-shakes scripts, removing unnecessary code and organizing the rest for faster loading.
Server-side rendering (SSR): Framer delivers pre-rendered content, improving loading speed, user experience, and search engine rankings.
Automatic sitemap generation: Framer creates a sitemap to ensure your site is crawlable and visible to search engines.
Consequences of not optimizing your website
Slow loading times: Unoptimized pages can frustrate visitors, increase bounce rates, and harm your site’s professionalism.
Poor SEO: Without SSR and sitemaps, search engines may struggle to index your site, resulting in lower rankings. Additionally, slow-loading pages are penalized in search rankings.
You can check optimization status under Settings → Domains or Settings → Versions.
Common cause: custom code components or overrides
Custom code that relies on browser-specific APIs, such as window, document, or navigator, may not optimize effectively. Framer’s server pre-renders pages without a browser environment, rendering these APIs unavailable.
To resolve these optimization errors, avoid using browser-dependent JavaScript during server-side rendering. Instead, consider using alternatives like CSS media queries in place of window.innerWidth.
Customizing based on user data
If your component needs browser-specific information like document.cookie or navigator.language:
Use placeholders: Create a component that shows a placeholder while loading, then updates after the page loads. Example: framer-optim-1.jsx.
Opt-out of optimization: Components can bypass optimization, but their content won’t be accessible to search engines. Use this method sparingly. Example: framer-optim-2.jsx.
For overrides: Use the same approach as components to handle overrides. Example: framer-optim-3.jsx.
By addressing these warnings and utilizing Framer’s built-in tools, you can enhance site performance, improve SEO, and create a better experience for your visitors.
