Message Extraction

This feature allows you to define and extract messages that can be used for localization. The `defineMessages` function is used to create a collection of messages with unique IDs, default messages, and descriptions.

const messages = defineMessages({
  greeting: {
    id: 'greeting',
    defaultMessage: 'Hello, World!',
    description: 'Greeting to welcome the user'
  }
});

Message Compilation

This feature compiles the defined messages into a format that can be used by the application. The `compile` function takes the messages and processes them for use in the application.

import { compile } from '@formatjs/ts-transformer';

const compiledMessages = compile(messages);

TypeScript Integration

This feature integrates with TypeScript's compiler to transform and process the messages during the build process. The `transform` function is used in the TypeScript configuration to apply the transformer.

import { transform } from '@formatjs/ts-transformer';

const tsConfig = {
  compilerOptions: {
    plugins: [{
      transform: '@formatjs/ts-transformer',
      type: 'config'
    }]
  }
};
