## What to know before using

- This package assumes it runs in the browser. I have taken many steps to prevent it from failing on the server, but still, it is recommended to only render the component on the client. See troubleshooting section for more information.

## Installation

```
npm install emoji-picker-react
```

## Usage

```jsx
import EmojiPicker from 'emoji-picker-react';

function App() {
  return (
    <div>
      <EmojiPicker />
    </div>
  );
}
```

    emoji: string; // the emoji character, for example: '😀'. Emoji ID in custom emojis
    isCustom: boolean; // whether the emoji is a custom emoji or not
    names: string[];
    imageUrl: string; // the url of the emoji image with the current emoji style applied
    getImageUrl: (emojiStyle: EmojiStyle) => string; // a function that receives an emoji style and returns the url of the emoji image with the provided style applied
  }
  ```

- `theme`: `Theme` - The theme of the picker. Can be `light`, `dark` or auto. Default is `light`.
  The `Theme` enum can be imported from the package.

  ```ts
  import { Theme } from 'emoji-picker-react';
  ```

  - ✋🏼 '1f3fc'
  - ✋🏽 '1f3fd'
  - ✋🏾 '1f3fe'

The skin tones typescript enum can be imported directly from the package:

```ts
import { SkinTones } from 'emoji-picker-react';
```

- `onSkinToneChange`: `(skinTone: SkinTones) => void` - Callback function when a skin tone is changed.

```ts
{
  defaultEmoji: string; // defaults to: "1f60a"

  showPreview: boolean; // defaults to: true
}
```

- `searchPlaceholder`: `string` - The placeholder text for the search input. Defaults to `Search`.

- categories: Allows full config over ordering, naming and display of categories.
  To only sort/omit categories, you can simply pass an array of category names to display:

  - 'suggested',
  - 'custom', - Hidden by default
  - 'smileys_people',
  - 'animals_nature',
  - 'food_drink',
  - 'travel_places',
  - 'activities',
  - 'objects',
  - 'symbols',
  - 'flags'

  For a more in-depth configuration, you can pass an array with category config:

  ```ts
  [
    {
      category: 'suggested',
      name: 'Recently Used'
    },
    {

  ```ts

## Custom Emojis

The customEmojis prop allows you to add custom emojis to the picker. The custom emojis prop takes an array of custom emojis, each custom emoji has three keys:

id: Unique identifier for each of the custom emojis
names: an array of string identifiers, will be used both for display, search and indexing.
imgUrl: URL for the emoji image

### Usage Example

```jsx
<Picker
  customEmojis={[
    {
      names: ['Alice', 'alice in wonderland'],
      imgUrl:
        'https://cdn.jsdelivr.net/gh/ealush/emoji-picker-react@custom_emojis_assets/alice.png',
      id: 'alice'
    },
    {
      names: ['Dog'],
      imgUrl:
        'https://cdn.jsdelivr.net/gh/ealush/emoji-picker-react@custom_emojis_assets/dog.png',
      id: 'dog'
    },
    {
      names: ['Hat'],
      imgUrl:
        'https://cdn.jsdelivr.net/gh/ealush/emoji-picker-react@custom_emojis_assets/hat.png',
      id: 'hat'
    },
    {
      names: ['Vest'],
      imgUrl:
        'https://cdn.jsdelivr.net/gh/ealush/emoji-picker-react@custom_emojis_assets/vest.png',
      id: 'vest'
    }
  ]}
/>
```

Here are some additional things to keep in mind about custom emojis:

- The custom emojis will be added to the Custom category.
- The location or name of the Custom category can be controlled via the categories prop.
- The custom emojis will be indexed by their id property. This means that you can search for custom emojis by their id or names.

## Reactions Picker

![image](https://github.com/ealush/emoji-picker-react/assets/11255103/48901306-e7fd-49cd-8f1e-9b214083a61d)

The picker can be used as a reactions picker. To use it as a reactions picker, you should set the reactionsDefaultOpen prop to true. This will cause the picker to the reactions picker on the initial mount instead of the main picker component.

To customize the reactions, you should pass an array of unified emoji ids to the reactions prop.

The reactions picker uses the same event handlers, and the same css variables for customizations.

```jsx
<Picker reactionsDefaultOpen={true} onReactionClick={handleReaction} />
```

# Customization

## Custom Picker Width and Height

To customize the dimensions of the picker, use the `height` and `width` props. You can pass in a number that will be treated as pixel size, or your any accepted css width/height as string.

```jsx
<EmojiPicker height={500} width={400} />
```

```jsx
<EmojiPicker height="100%" width="15em" />
```

## CSS Variables

The picker can be customized via css variables. The root selector for the picker is `.EmojiPickerReact`, when overriding, make sure to provide a more specific selector.

In dark mode, the specific selector is `.EmojiPickerReact.epr-dark-theme`.

The list of possible variables is quite extensive, but the main ones you may want to override are:

- `--epr-emoji-size`: The size of the emojis.
- `--epr-emoji-gap`: The space between emojis.

- `--epr-hover-bg-color` Hovered emoji background color.
- `--epr-bg-color`: The background color of the picker. When changing it, you should also change `--epr-category-label-bg-color` as they are usually the same color.
- `--epr-text-color`: The text color in the picker.

# Rendering Output Emojis in Your App

The picker exports an `Emoji` component. The emoji component is the same used within the picker, so it will render the same way as the emojis in the picker. You can choose to render emojis either as native, or as images.

# Troubleshooting

## Error Boundary

emoji-picker-react has a top-level error boundary, trying to catch rendering errors. It won't catch server side related errors, or event handlers errors. If an error is caught, the picker will not render, and a console error will be logged.

## Next.js

To avoid errors such as "document is not defined" on the server side, you should make sure the library is only imported on the client side. Here is how to do that:

```javascript
import dynamic from 'next/dynamic';

const Picker = dynamic(
  () => {
    return import('emoji-picker-react');
  },
  { ssr: false }
);
```

## Vite

For reference, if you only need to shim global, you can add

```html
<script>
  window.global = window;
</script>
```
