babel-plugin-tailwind-rn-classname v0.0.3

babel-plugin-tailwind-rn-classname

Babel plugin to use your tailwind classes directly in React Native.

You will have standard autocompletion from you IDE, and your tailwind plugins will work like in a standard React app.

It has an optimised behaviour: it detects static classes and convert them to object directly at transpilation time for better performances, and let the dynamic ones for runtime.

It uses tailwind-rn package under the hood, which is a peer dependency.

Installation

yarn add tailwind-rn
yarn add -D babel-plugin-tailwind-rn-classname

or

npm install --save tailwind-rn
npm install --save-dev babel-plugin-tailwind-rn-classname

Setup

Basic

Add it to your .babelrc (or any Babel config file)

{
  "plugins": [
    "tailwind-rn-classname"
  ]
}

Custom

If you want to customise your styles as described in the tailwind-rn documentation, you can pass options to the plugin:

{
  "plugins": [
    [
      "tailwind-rn-classname",
      {
        "tailwindRNExportPath": "my/custom/module",
        "tailwindRNExportName": "tailwind"
      }
    ]
  ]
}

So considering a root tailwindRN.ts file which contains:

import { create } from 'tailwind-rn';
import styles from './styles.json';

const { tailwind, getColor } = create(styles);

export const tw = tailwind

the configuration will be:

{
  "plugins": [
    [
      "tailwind-rn-classname",
      {
        "tailwindRNExportPath": "./tailwindRN",
        "tailwindRNExportName": "tw"
      }
    ]
  ]
}

Typescript

To be allowed to use a className attribute on all your component, you have to add the babel-plugin-tailwind-rn-classname types to your "types" array in tsconfig.json.

{
  "compilerOptions": {
    "types": [
      "babel-plugin-tailwind-rn-classname"
    ]
  }
}

Usage

Write your tailwind classes like you would do on standard React app. You can find the list of supported utilities on tailwind-rn documentation

const Component = ({ isAlert = false }) => (
  <SafeAreaView className="h-full">

      <View className={`${isAlert ? 'bg-orange-200' : 'bg-blue-200'} px-3 py-1 rounded-full`}>
        <Text className={`${isAlert ? 'text-orange-800' : 'text-blue-800'} font-semibold`}>
