title: preRender
---
The `preRender` hook is triggered just before your pattern is rendered to SVG.
The `preRender` lifecycle hook is triggered just before your pattern is
rendered to SVG.
Your hook method will receive [the SVG object](/api/svg) as its first parameter.
## Signature
It is typically used to change the result of the render, for example by adding CSS to the SVG output.
```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.
