babel-plugin-react-intl-auto

i18n for the component age. Auto management react-intl ID.

React Intl is awesome. But, Global ID management is difficult and confusing.

Many projects, like react-boilerplate, give the ID to the name of the component as a prefix. But it is redundant and troublesome.

This babel-plugin releases you from cumbersome ID management. Based on the file path, this automatically generate a prefixed id.

Also, we strongly encourage you to use extract-react-intl-messages. You can generate json automatically.

Goodbye, global ID!!

Before

import { defineMessages, FormattedMessage } from 'react-intl'

export default defineMessages({
  hello: {
    id: 'App.Components.Greeting.hello',
    defaultMessage: 'hello {name}',
  },
  welcome: {
    id: 'App.Components.Greeting.welcome',
    defaultMessage: 'Welcome!',
  },
})

const MyComponent = () => (
  <FormattedMessage
    id="App.Components.Greeting.goodbye"
    defaultMessage="goodbye {name}"
  />
)

After

With babel-plugin-react-intl-auto.

import { defineMessages, FormattedMessage } from 'react-intl'

export default defineMessages({
  hello: 'hello {name}',
  welcome: 'Welcome!',
})

const MyComponent = () => <FormattedMessage defaultMessage="goodbye {name}" />

See examples.

With `extract-react-intl-messages`

Example usage with extract-react-intl-messages.

$ extract-messages -l=en -o translations 'src/**/*.js'

en.json

{
  "components.App.hello": "hello {name}",
  "components.App.welcome": "Welcome",
  "components.App.189751785": "goodbye {name}" // unique hash of defaultMessage
}

Install

npm

$ npm install --save-dev babel-plugin-react-intl-auto

yarn

$ yarn add --dev babel-plugin-react-intl-auto

Usage

.babelrc

{
  "plugins": [
    [
      "react-intl-auto",
      {
        "removePrefix": "app/",
        "filebase": false
      }
    ]
  ]
}

Options

removePrefix

remove prefix.

Type: string | boolean
Default: ''

if removePrefix is true, no file path prefix is included in the id.

Example (src/components/App/messages.js)

when removePrefix is "src"

import { defineMessages } from 'react-intl';

export default defineMessages({
  hello: 'hello world'
});

      ↓ ↓ ↓ ↓ ↓ ↓

import { defineMessages } from 'react-intl';

export default defineMessages({
  hello: {
    id: 'components.App.hello',
    defaultMessage: 'hello world'
  }
});

when removePrefix is true

import { defineMessages } from 'react-intl';

export default defineMessages({
  hello: 'hello world'
});

      ↓ ↓ ↓ ↓ ↓ ↓

import { defineMessages } from 'react-intl';

export default defineMessages({
  hello: {
    id: 'hello',
    defaultMessage: 'hello world'
  }
});

filebase

Type: boolean
Default: false

if filebase is true, generate id with filename.

includeExportName

Type: boolean | 'all'
Default: false

if includeExportName is true, adds named exports as part of the id.

Only works with defineMessages.

Example

export const test = defineMessages({
  hello: 'hello {name}',
})

      ↓ ↓ ↓ ↓ ↓ ↓

export const test = defineMessages({
  hello: {
    id: 'path.to.file.test.hello',
    defaultMessage: 'hello {name}',
  },
})

If includeExportName is 'all', it will also add default to the id on default exports.

extractComments

Use leading comments as the message description.

Only works with defineMessages

Type: boolean
Default: true

Example

export const test = defineMessages({
  // Message used to greet the user
  hello: 'hello {name}',
})

      ↓ ↓ ↓ ↓ ↓ ↓

export const test = defineMessages({
  hello: {
    id: 'path.to.file.test.hello',
    defaultMessage: 'hello {name}',
    description: 'Message used to greet the user',
  },
})

Support variable

Example

const messages = { hello: 'hello world' }

export default defineMessages(messages)

      ↓ ↓ ↓ ↓ ↓ ↓

const messages = {
  hello: {
    id: 'path.to.file.hello',
    defaultMessage: 'hello wolrd'
  }
};

export default defineMessages(messages);

babel-plugin-react-intl-id-hash

If you want short consistent hash values for the ID, you can use react-intl-id-hash in addition to this plugin to help reduce your applications bundle size.
