# UNSAFE_DOCUMENT_WRITE: document.write in the component

> document.write in the component

| Severity | Fault                         | Stage        |
| -------- | ----------------------------- | ------------ |
| error    | customer (the source package) | build output |

## What it means

The component calls document.write, document.writeln or document.open, which write into or replace the whole host page outside the component's shadow root (rule document-write).

## How to fix

Render inside the component with JSX; to print, open a window the component builds with DOM methods, never document.write.
