title: preRender
---

The `preRender` lifecycle hook is triggered just before your pattern is
rendered to SVG.

## Signature

```js
null hook(Svg svg)
```

## Notes

The `preRender` hook is typically used to change the result of the render, for
example by adding CSS to the SVG output.

Like the `postRender` hook, it receives [the SVG object](/api/svg) as its first
parameter.

feat: Flat import of markdown repo This is a flat (without history) import of (some of) the content from our markdown module. We've imported this without history because the repo contains our blog posts and showcases posts content prior to porting them to strapi. Since this contains many images, it would balloon the size of this repo to import the full history.
