# Ratatui Core [![Crates.io](https://img.shields.io/crates/v/ratatui-core)](https://crates.io/crates/ratatui-core) [![Documentation](https://docs.rs/ratatui-core/badge.svg)](https://docs.rs/ratatui-core) [![License](https://img.shields.io/crates/l/ratatui-core)](../LICENSE) **ratatui-core** is the core library of the [ratatui] project, providing the essential building blocks for creating rich terminal user interfaces in Rust. [ratatui]: https://github.com/ratatui/ratatui ### Why `ratatui-core`? The `ratatui-core` crate is split from the main [`ratatui`](https://crates.io/crates/ratatui) crate to offer better stability for widget library authors. Widget libraries should generally depend on `ratatui-core`, benefiting from a stable API and reducing the need for frequent updates. Applications, on the other hand, should depend on the main `ratatui` crate, which includes built-in widgets and additional features. ## Installation Add `ratatui-core` to your `Cargo.toml`: ```shell cargo add ratatui-core ``` ## Crate Organization `ratatui-core` is part of the Ratatui workspace that was modularized in version 0.30.0 to improve compilation times, API stability, and dependency management. This crate provides the foundational types and traits that other crates in the workspace depend on. **When to use `ratatui-core`:** - Building widget libraries that implement [`Widget`] or [`StatefulWidget`] - Creating lightweight applications that don't need built-in widgets - You want minimal dependencies and faster compilation times - You need maximum API stability (core types change less frequently) **When to use the main [`ratatui`] crate:** - Building applications that use built-in widgets - You want convenience and don't mind slightly longer compilation times - You need backend implementations and terminal management utilities For detailed information about the workspace organization, see [ARCHITECTURE.md].
