react-native-iconic-font

Use iconic font in a simple way.

Usage

Notice: Android added custom font support in v0.16, so make sure your native dependency is above it:

compile 'com.facebook.react:react-native:0.16.+'

1. install module
   npm install --save react-native-iconic-font

step 2 and 3 are same as official way to use custom font.

2. copy font file

   • font files are under node_modules/react-native-iconic-font/fonts/
   • just copy the file you want to use
   • android: copy file to [project root]/android/app/src/main/assets/fonts/
   • ios: see https://github.com/oblador/react-native-vector-icons#option-manually

3. import to use

var icon = require('react-native-iconic-font/fontawesome');

...

React.createClass({
  render: function() {
  //FontFamily perproty value must same as font file name.
    return (
       <Text style={{fontFamily: 'fontawesome',fontSize:30}}> 
                twitter-icon:{icon('twitter')}
       </Text>
    );
  }
});

Reload js and you'll see the icon there.

##Icon Fonts

• Font-awesome
• foundation-icons
• ionicons
• octicons
• typicons
• weathericons
• material-design-icons ...

In fact, it will be so easy to use any iconic font after you read this article.

What's the difference?

There are already some good solutions to use iconic font :
https://github.com/oblador/react-native-vector-icons
https://github.com/lwhiteley/react-native-android-iconify
https://github.com/corymsmith/react-native-icons

But ... these libraries all require native code and/or native project config file modifications.
Believe me, it confused many javascript developers who are familar with 'native code'.
That's why i start this project .
No native code. Let's try to use pure javascript!

How

A font system is basically a 'character-graph' mapping.
In a web page, CSS rules deal with webfonts like this:

<i class="fa-twitter">
==CSS rules==> .fa-twitter:before{content: "\f099";} 
                                 ==font system==>  a twitter graph

It's the same process in React Native except the CSS rules. That's what this project does. Mapping names to characters.

Besides I created a command tool to transform a CSS file to these mapping module.

Run one command to generate the js module
iconmap -f test/font-awesome-v4.4.0.css -p '^\.fa-([a-z0-9-]+?):before$'
