eslint-plugin-i18next

ESLint plugin for i18n

For old versions below v6, plz refer this document

Installation

npm install eslint-plugin-i18next --save-dev

Usage

For ESLint 9 flat configuration,

// eslint.config.mjs
import i18next from 'eslint-plugin-i18next';

export default [
  // your other configs
  i18next.configs['flat/recommended'],
];

For ESLint 8 and below,

// .eslintrc
{
  "extends": ["plugin:i18next/recommended"]
}

Rule no-literal-string

This rule aims to avoid developers to display literal string directly to users without translating them.

Note: Disable auto-fix because key in the call i18next.t(key) usually was not the same as the literal

Example of incorrect code:

/*eslint i18next/no-literal-string: "error"*/
<div>hello world</div>

Example of correct code:

/*eslint i18next/no-literal-string: "error"*/
<div>{i18next.t('HELLO_KEY')}</div>

Breaking change

By default, it will only validate the plain text in JSX markup instead of all literal strings in previous versions. You can change it easily
