• Category: Performance

• Framework: global
• Enabled when: always
• Default: Enabled

Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Confirm the reported code matches document.write/writeln. Check the framework context and diagnostic message before suppressing it.

Fix prompt

Use this once validation confirms the diagnostic is real.

Don't use document.write()/document.writeln(). Append DOM nodes or set innerHTML/textContent on a specific element instead.

Related rules

More Performance rules from the rules reference:

• react-doctor/no-dynamic-import-path: Use a string-literal path: `import('./feature/heavy.js')` so the bundler can split this chunk
• react-doctor/no-flush-sync: Use startTransition for non-urgent updates — flushSync forces a sync flush that skips View Transitions and concurrent rendering
• react-doctor/no-full-lodash-import: Import the specific function: `import debounce from 'lodash/debounce'` — saves ~70kb
• react-doctor/no-global-css-variable-animation: Set the variable on the nearest element instead of a parent, or use `@property` with `inherits: false` to prevent cascade. Better yet, use targeted `element.style.transform` updates
• react-doctor/no-img-lazy-with-high-fetchpriority: Lazy image with high fetchPriority
