React Native Emoji Input

A performant, customizable keyboard input for React Native. Built for and used in Opico.



npm install --save react-native-emoji-input


yarn add react-native-emoji-input

If you make changes to the emoji synonyms files, you need to recompile the data sources. To compile the emoji dataset, run:

npx babel-node scripts/compile.js

Default Props

Prop Description type
onEmojiSelected A handler for the selected emoji function

Optional Props

Prop Description type default value
keyboardBackgroundColor Set the background color of the main keyboard pane string '#E3E1EC'

showCategoryTab Whether the categories should be shown or not boolean true
enableSearch Whether the search bar should be shown or not boolean true
showCategoryTitleInSearchResults Whether the search title should be shown or not in search results boolean false
enableFrequentlyUsedEmoji Whether the frequently used category should be shown or not boolean true
defaultFrequentlyUsedEmoji An array of keys for emojis that will always render in the frequently used category Array(string) []
resetSearch Pass this in if you want to clear the the search boolean false
loggingFunction Logging function to be called when applicable.* function none
verboseLoggingFunction Same as loggingFunction but also provides strategy used to determine failed search boolean false

* When the search function yields this function is called. Additionally when the user clears the query box this function is called with the previous longest query since the last time the query box was empty. By default the function is called with one parameter, a string representing the query. If the verbose logging function parameter is set to true the function is called with a second parameter that is a string specifying why the function was called (either 'emptySearchResult' or 'longestPreviousQuery').


	onEmojiSelected={(emoji) => {console.log(emoji)}}

Compile emoji-data from source

The project is using iamcal/emoji-data. We only use the emoji.json that contains all the Unicode characters, short names, keywords, and categories. To embrace the latest version of Emoji, we suggest to compile the json file from source.

# You need first check out the `emoji-data` repo. We will use the compile tool provided in the repo.
git clone
cd emoji-data/build

# Pull data from Unicode standard

# Add new shortnames. Here're some examples in current dir, check out data_emoji_names.txt, data_emoji_names_v4.txt
vim data_emoji_names_vxx.txt # xx should be version of emoji, e.g. 11

# Compile from spec files into json
php build_map.php

Then copy the emoji-data/emoji.json to src/emoji-data/emoji-data.json and make sure the entry point is point to this json file.

// src/emoji-data/index.js
import emoji from './emoji-data.json';

Finally compile the data file that used in the keyboard.

node-babel ./scripts/compile.js
