    This plugin has been deprecated. Please use @calm/eslint-plugin-react-intl instead. npm: github:


    This is a plugin to ensure that Intl translations are being made correctly with react-intl. Since they should be stored in an object for translation, this disables plain text between html tags.

    There are three options to enable, and we recommend enabling all of them to ensure proper translations in all languages.

    The { noTrailingWhitespace: true } option is set by default and is not necessary to declare in the rules section. This is recommended as some languages don't have spaces between words. Additionally, the option ignoreLinks is set to true by default. Depending on your use case, you may want to disable this.

    Use Cases

    FormattedMessage validation

    • Checks to make sure plain text doesn't exist within html tags (should be translated)
    • <a> tags by default are not checked (this can be disabled)
    • Numbers are ignored (they're the same in every language)
    • Trailing whitespace is not allowed (this can be disabled)

    Missing Values validation

    • In defaultMessage attributes within components, {variable} declarations must be declared in the values attribute
    • It will look over anything before a comma, allowing for FormatJS plurals
      • Ex. defaultMessage="{number} {number, plural, one {Day} other {Days}}" will resolve 1 variable as number

    Missing Attribute validation

    • components must have both defaultMessage and id attributes set
    • defaultMessage and id attributes cannot be empty
    • Spread operator by default is not allowed
      • Spread operator can't be evaluated by eslint's AST, so translations can't be guaranteed


    You'll first need to install ESLint:

    $ npm i eslint --save-dev

    Next, install eslint-plugin-react-intl-format:

    $ npm install eslint-plugin-react-intl-format --save-dev

    Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-react-intl-format globally.


    Add react-intl-format to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

        "plugins": [

    Then configure the rules you want to use under the rules section. Currently there's just one rule: 'missing-formatted-message'.

        "rules": {
            "react-intl-format/missing-formatted-message": [2, { "noTrailingWhitespace": true, "ignoreLinks": true }],
            "react-intl-format/missing-attribute": [2, { "noTrailingWhitespace": true, "noSpreadOperator": true }],
            "react-intl-format/missing-values": 2

    Supported Rules

    • missing-formatted-message
    • missing-attribute
    • missing-values


    npm i eslint-plugin-react-intl-format
