Extract react-intl messages

This repo was migrated to the extract-react-intl-messages

extract-react-intl

This package allows you to extract all messages from a glob. It will return an object with a key for each locale you pass, which in turn contains an object with the ids of each message defined by the defineMessages function of react-intl. The value of each of these keys will be an empty string, except for your defaultLocale which will be populated with the defaultMessage.

Install

$ yarn add --dev extract-react-intl

Usage

const extractReactIntl = require('extract-react-intl')

const pattern = 'app/**/*.js'
const locales = ['en', 'ja']

extractReactIntl(locales, pattern).then(result => {
  console.log(result)
  /*
{
  en:
   { 'components/App/hello': 'hello',
     'components/App/welcome': 'welcome to extract-react-intl' }
  ja:
   { 'components/App/hello': '',
     'components/App/world': '' }
}
  */
})

extract-react-intl's Issues

Enable passing babel-plugin-react-intl options.

Feature

What is the expected behavior?:
I have a case where I've wrapped react-intl with my own module with some custom functions and components to manage internationalization. I don't want the need to import some elements from it and some from react-intl. I prefer to use just one source. I've mentioned it in this issue.

babel-plugin-react-intl accepts few options to manipulate extracting process. With extract-react-intl context, most of them are not so helpful (especially if we assume using it with by extract-react-intl-messages), but one is. I mean moduleSourceName which lets plugin to know from where defineMessages or <FormattedMessage /> is imported. Of course, default is react-intl but in some cases one may want to use custom module.

Suggested solution:
It would be great to be able to pass custom module name to extract-react-intl which can forward it to babel-plugin-react-intl (I've tested it locally, simply by explicitly adding options to unshifted preset in the source code and it works).

Same thing would fit extract-react-intl-messages.

@akameco, I can try to manage some changes if you want (but never done that on someones github repo 😉 ).

babel-plugin-react-intl execution order can cause unexpected errors

• version: 0.5.1
• node version: 8.9.3
• npm (or yarn) version: yarn 1.3.2

What is the current behavior?:

Since extract-react-intl pushes babel-plugin-react-intl into the plugins list, it will be executed ahead of any user configured babel presets.

So if I have a preset:

// my-preset.js
{
  "presets": ["env", "stage-3"],
  "plugins": ["react-intl-auto"]
}

and I use that in my projects .babelrc:

//.babelrc
{
  presets: ["my-preset"]
}

then because of this line:

plugins.push(require('babel-plugin-react-intl').default)

The following are the options passed to transformFile inside extract-react-intl:

{
  presets: ['/some/path/to/my-preset.js'],
  plugins: ['/some/path/to/babel-plugin-react-intl/index.js'],
}

Babel prioritizes plugins in the top level config BEFORE plugins in any presets.

The result in my case above is that babel-plugin-react-intl is called BEFORE babel-plugin-react-intl-auto which is problematic.

If I had the following .babelrc file it will work because the plugins aren't in a preset:

//.babelrc
{
  presets: ["my-preset"],
  plugins: ["react-intl-auto"],
}

What is the expected desired behavior?:

I'd love to find a way for all the user's babel config/presets/plugins to be run before babel-plugin-react-intl so that I don't have to worry about the order of my own babel config to make this tool work.

Suggested solution:

If you were to unshift babel-plugin-react-intl into the presets instead of plugins, it'd make it lower in the execution order for babel:

- plugins.push(require('babel-plugin-react-intl').default)
+ presets.unshift({ plugins: [require('babel-plugin-react-intl').default] })

PeerDep warning + duplicate plugin errors

What is the current behavior?:

$ extract-messages -l=source -o server/lang -d source --flat 'src/**/!(*.test).js'
Error: Duplicate plugin/preset detected.
If you'd like to use two separate instances of a plugin,
they need separate names, e.g.

  plugins: [
    ['some-plugin', {}],
    ['some-plugin', {}, 'some unique name'],

error Command failed with exit code 1.

What is the expected behavior?:
We're running babel 7 in our project, so I followed the instruction re: babel-core@bridge. Unfortunately the error still persists. I added some logging, and name in the assertNoDuplicated function is empty (these are added to a map to verify lack of duplication).

Suggested solution:
I'm not sure why it's still using "@babel/core" instead of babel-core, despite babel-core@bridge being installed. Any thoughts>
