@ discord/ jest- 处理器- discord- intl

一个处理器插件,用于 Jest 处理 intl 信件定义和翻译 @discord/intl。 。 。 .

在您的 Jest 配置中, 将此添加为消息文件模式的变压器 :

module.exports = {
  transform: {
    // Order matters here! Even though this is an Object, Jest still processes these first to
    // last (object insertion order). These patterns can overlap, so we want to put all of the
    // special handling first.
    [INTL_MESSAGES_FILE_PATTERN]: require.resolve('@discord/jest-processor-discord-intl'),
    // ...other transforms, like `*.tsx?` and more.
  },
};

您还需要使用 bayl 插件来转换消费代码, 如普通的捆绑 :

// In a custom processor or wherever you configure Babel for Jest:
babel.transform({
  // ...
  plugins: [
    [
      require.resolve('@discord/babel-plugin-transform-discord-intl'),
      {
        // Jest does _not_ resolve these to absolute paths, so tell the plugin to use the
        // original import paths instead of resolving them like it does for Metro.
        preserveImportSource: true,
        extraImports: {
          '@app/intl': ['t', 'untranslated', 'international'],
        },
      },
    ],
  ],
});
