eslint-plugin-react-native-a11y

Eslint-plugin-react-native-a11y is a collection of React Native specific ESLint rules for identifying accessibility issues. Building upon the foundation set down by eslint-plugin-jsx-a11y, eslint-plugin-react-native-a11y detects a few of the most commonly made accessibility issues found in react native apps. These rules make it easier for your apps to be navigable by users with screen readers.

Installation

Install ESLint:

# npm
npm install eslint --save-dev

# yarn
yarn add eslint --dev

Next, install eslint-plugin-react-native-a11y:

# npm
npm install eslint-plugin-react-native-a11y --save-dev

# yarn
yarn add eslint-plugin-react-native-a11y --dev

Note: If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-react-native-a11y globally.

Usage

Add react-native-a11y to the plugins section of your .eslintrc configuration file.

{
  "plugins": ["react-native-a11y"]
}

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "react-native-a11y/rule-name": 2
  }
}

Alternatively, you can enable all the recommended rules at once by adding plugin:react-native-a11y/recommended to the extends section of your .eslintrc configuration file:

{
  "extends": [
    "plugin:react-native-a11y/recommended"
  ]
}

Supported Rules

Rule Options

The following options are available to customize the recommended rule set.

Custom Touchables

react-native-a11y/has-accessibility-props and react-native-a11y/no-nested-touchables allow you to define an array of names for custom components that you may have that conform to the same accessibility interfaces as Touchables. Each of these names must start with 'Touchable'.

"react-native-a11y/has-accessibility-props": [
  "error",
  {
    "touchables": ["TouchableCustom"]
  }
]
