# @lingui/format-json

> Reads and writes Lingui message catalogs as JSON, either minimal key-value files or files with full message metadata

`@lingui/format-json` is part of [Lingui][documentation]. Lingui is a lightweight, open-source internationalization (i18n) library for JavaScript and TypeScript. It brings compile-time macros and a CLI for message extraction to React, React Native, Vue, SolidJS, Astro, Svelte, and Node.js.

The `minimal` style is a flat object of message IDs and translations. The `lingui` style keeps the source message, comments and origins alongside each translation.

## Usage

See the [catalog formats reference][reference].
