Verifying Static Output
A step-by-step guide to proving that a page renders its content without client JavaScript.
A page is only static-first if the content is in the bytes the server sends. This guide shows how to assert that from the build output.
Steps
- Build the site and locate the emitted HTML files.
- Read each file as bytes, not through a browser.
- Assert the primary content string is present.
- Assert exactly one canonical link is present.
- Assert no executable script is required for the content.
Frequently asked questions
- Is a screenshot enough evidence?
- No. A screenshot can come from a browser that executed JavaScript. Read the raw HTML bytes instead.
