#### 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
* Calm chooses to always require these, but you can optionally disable defaultMessage with option `requireDefaultMessage : false`
* `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
* `requireDescription` can optionally be set to require that all translations contain the description attribute
* Use the `formatDefineMessages: true` option in order to also check the defineMessages declaration from react-intl
* *BE CAREFUL* - This assumes that defineMessages will always mean the react-intl method, so do not declare other defineMessages functions unless they maintain the same formatting as react-intl
* Optional `requireIdAsString: false` will allow for variables in the id field
* *BE CAREFUL* - variables in id fields can result in duplicate strings being translated, as well as the possibility of a changed variable leading to an id without a translation associated with it

## Installation

You'll first need to install [ESLint](http://eslint.org):

```
$ npm i eslint --save-dev
```

Next, install `@calm/eslint-plugin-react-intl`:

```
$ npm install @calm/eslint-plugin-react-intl --save-dev
```

**Note:** If you installed ESLint globally (using the `-g` flag) then you must also install `@calm/eslint-plugin-react-intl` globally.

## Usage

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

```json
{
"plugins": [
"@calm/react-intl"
]
}
```

Then configure the rules you want to use under the rules section.
It's recommended that you explicitly set each option.


The rules (with their default settings) are listed below.

```json
{
"rules": {
"@calm/react-intl/missing-formatted-message": [2,
{
"noTrailingWhitespace": true,
"ignoreLinks": true,
"enforceLabels": false,
"enforceImageAlts": false,
"enforceInputProps": false
}
],
"@calm/react-intl/missing-attribute": [2,
{
"noTrailingWhitespace": true,
"noSpreadOperator": true,
"requireDescription": false,
"formatDefineMessages": false,
"requireIdAsString": true,
"requireDefaultMessage": true,
}
],
"@calm/react-intl/missing-values": 2
}
}
```
