## π Installation
This project uses react hooks and is therefore reliant on react version >=16.8.6
To install and use react-anchor-navigation, add it to your package.json and modules with the following command line :
```ts
npm install --save react-anchor-navigation
```
OR
```ts
yarn add react-anchor-navigation
```
## π₯οΈ How to use
```tsx
import {
AnchorContext,
AnchorLink,
AnchorProvider,
AnchorSection,
} from "react-anchor-navigation";
```
#### AnchorProvider
AnchorProvider is our top level contextProvider. Wrap it around your topmost component for your view :
```tsx
```
| Key | Type | Description |
| ----------- | :-----------------: | ---------------------------------------------------------------------------------------------------------------: |
| offset | `number` | The offset amount of pixels from the top, usefull when handling fixed header or sticky navigation (default: `0`) |
| getScroller | `() => HTMLElement` | Function to returns the scrollable element (default: `body`) |
It will provide the AnchorContext to all children.
#### AnchorContext
AnchorContext is the context you can yield with the new `useContext` hook or with old-fashioned Context.consumer.
```ts
const { hash, sections } = useContext(AnchorContext);
```
Here is its typing :
| Key | Type | Description |
| ----------------- | :---------------------------------------------: | -------------------------------------------------------------------------------------------------------------------------------: |
| sections | `HTMLElement[]` | List of the registered sections elements that we watch, in our codebase it is AnchorSection |
| hash | `string` | The registered hash corresponding to our current scroll position |
| registerSection | `(element: HTMLElement) => void` | Function to add a Section to our sections list, our scrollEvent listener will then update the hash if the section is scrolled to |
| unregisterSection | `(element: HTMLElement) => void` | Function to remove a Section to our sections list, our scrollEvent listener will then stop checking this section |
| setHash | `(hash: string, withScroll?: boolean) => void;` | Setter function from the internal useHash hooks, use it to programmatically change the current hash |
| offset | `number` | The offset amount of pixels from the top, usefull when handling fixed header or sticky navigation (default: `0`) |
#### AnchorSection
AnchorSection is our most used components, it defines the scroll position you will arrive to on navigation/reloading
```ts
```
Its props are the usual HTMLElement's props (`className, data-*`), along with an id used for recognizing the update the current hash on scroll.
```ts
interface TProps extends React.HTMLAttributes {
id: string;
}
```
Internally it creates a `` tag to which we scroll to on reload and detect if we scrolled past it.
```tsx
<>
{...children}
>
```
#### AnchorLink
AnchorLink is a component made to have an activeClassname if its `href` is the current hash
```ts
interface TProps extends React.AnchorHTMLAttributes {
children: React.ReactNode[] | React.ReactNode;
activeClassName?: string;
}
```
```tsx
```
## β³ How to test
react-anchor-navigation can be tested with the end-to-end testing library Cypress.
To run the tests, run `yarn cypress` and select the test specs to run in the Cypress window.
