## Getting started
Please install stickyroll and react. Stickyroll does not have any additional dependencies.
**With NPM**
```shell
npm install @stickyroll/react react react-dom
```
**With Yarn**
```shell
yarn add @stickyroll/react react react-dom
```
## Basic usage
```jsx
import Stickyroll from "@stickyroll/react/stickyroll";
export default function App() {
return Scroll here.;
}
```
## Adjusting pages and factor usage
```jsx
import Stickyroll from "@stickyroll/react/stickyroll";
export default function App() {
return (
// Uses 10 pages of 300vh each
Scroll here.
);
}
```
## Using listeners
```jsx
import Stickyroll from "@stickyroll/react/stickyroll";
export default function App() {
return (
{
console.log("onStart");
}}
onPage={(page, index) => {
console.log("onPage", page, index);
}}
onProgress={(progress, page, index) => {
console.log("onProgress", progress, page, index);
}}
onEnd={() => {
console.log("onEnd");
}}
>
Scroll here.
);
}
```
## Using CSS variables
- height: `CSS_VARS.height`
- pages: `CSS_VARS.pages`
- factor: `CSS_VARS.factor`
- progress: `CSS_VARS.progress`
- page: `CSS_VARS.page`
```jsx
import Stickyroll from "@stickyroll/react/stickyroll";
import { CSS_VARS } from "@stickyroll/react/constants";
export default function App() {
return (
);
}
```
## Using ClassNames
- root: `CLASS_NAMES.root`
- above: `CLASS_NAMES.above`
- below: `CLASS_NAMES.below`
- sticky: `CLASS_NAMES.sticky`
- nonSticky: `CLASS_NAMES.nonSticky`
- page: `CLASS_NAMES.page` (`type: function`)
```jsx
import styled from "@emotion/styled";
import Stickyroll from "@stickyroll/react/stickyroll";
import { CLASS_NAMES } from "@stickyroll/react/constants";
const StyledComponent = styled.div`
height: 10px;
background: red;
/* Active while in sticky mode */
&.${CLASS_NAMES.sticky} {
background: yellow;
}
/* Active before sticky mode */
&.${CLASS_NAMES.above} {
background: blue;
}
/* Active after sticky mode */
&.${CLASS_NAMES.below} {
background: hotpink;
}
/* Active while on page 0 (index) */
&.${CLASS_NAMES.page(0)} {
background: rebeccapurple;
}
`;
export default function App() {
return (
);
}
```
## Using the hook
```jsx
import { CSS_VARS, STYLE } from "@stickyroll/react/constants";
import useStickyroll from "@stickyroll/react/use-stickyroll";
import { useRef } from "react";
export default function App() {
const ref = useRef();
useStickyroll(ref, { pages: 1 });
return (
Scroll here.
);
}
```
## Advanced usage
You can provide your own styles and behavior to adjust stickyroll to your needs. Take a look at the
examples:
- [Demo](https://react-stickyroll.vercel.app/?path=/story/examples--apple)
- [Source](https://github.com/pixelass/react-stickyroll/blob/main/stories/examples.stories.tsx)
## Why we don't use States
While you can write the output of stickyroll to a state we recommend to work without states, to
optimize performance.
You can access the ref (see
[the example](https://github.com/pixelass/react-stickyroll/blob/main/stories/examples.stories.tsx))
and modify the styles and additional behavior from there.
If you still need a state, we recommend using a global state that can then be accessed in child
components to prevent re-rendering the top level component.
You can take a look at these state management libraries or use your own preferred library:
- [Zustand](https://github.com/pmndrs/zustand)
- [Jotai](https://github.com/pmndrs/jotai)
## Typescript
Stickyroll provides types and is fully typed. Use them, don't use them… if you ever need them, we've
got you covered.
## Testing
We test stickyroll in real browsers with real interactions to ensure full coverage and reliability
of this library.
