    "inline": false
  } ]
}

Via CLI

$ babel --plugins transform-format-message script.js

Via Node API

require("babel-core").transform("code", {
  plugins: [
    [ "transform-format-message", {
      "generateId": "underscored_crc32",
      "translations": "./locales",
      "locale": "pt-BR"
    } ]
  ]
})

Options

generateId is either a function string -> string, or one of "literal", "normalized", "underscored", "underscored_crc32". Default is "underscored_crc32".
inline is a boolean. If true, the full translated message will be inlined and optimized, otherwise only generated ids will be added. Default is false.
locale is the BCP 47 Language Tag string specifying the target language to inline. This is only used with inline: true. Default is "en".
translations is an object of the form: { [locale]: { [id]: { message: '...' }, ... } }. This is an object with keys for each locale, with values matching the extract-format-message json output. This can also be a string path to require a module that exports a matching object.
missingTranslation is one of "ignore", "warning", "error". Default is "warning".
missingReplacement is an optional string to use in place of missing translations. By default the default message will be used.
