Chorus is a Rust library which poses as an API wrapper for [Spacebar Chat](https://github.com/spacebarchat/) and Discord. It is designed to be easy to use, and to be compatible with both Discord and Spacebar Chat. You can establish as many connections to as many servers as you want, and you can use them all at the same time. ## A Tour of Chorus Chorus combines all the required functionalities of a user-centric Spacebar library into one package. The library handles various aspects on your behalf, such as rate limiting, authentication and maintaining a WebSocket connection to the Gateway. This means that you can focus on building your application, instead of worrying about the underlying implementation details. To get started with Chorus, import it into your project by adding the following to your `Cargo.toml` file: ```toml [dependencies] chorus = "0.14.0" ``` ### Establishing a Connection To connect to a Spacebar compatible server, you need to create an [`Instance`](https://docs.rs/chorus/latest/chorus/instance/struct.Instance.html) like this: ```rs use chorus::instance::Instance; #[tokio::main] async fn main() { let instance = Instance::new("https://example.com") .await .expect("Failed to connect to the Spacebar server"); // You can create as many instances of `Instance` as you want, but each `Instance` should likely be unique. dbg!(instance.instance_info); dbg!(instance.limits_information); } ``` This Instance can now be used to log in, register and from there on, interact with the server in all sorts of ways. ### Logging In Logging in correctly provides you with an instance of `ChorusUser`, with which you can interact with the server and manipulate the account. Assuming you already have an account on the server, you can log in like this: ```rs use chorus::types::LoginSchema; // Assume, you already have an account created on this instance. Registering an account works // the same way, but you'd use the Register-specific Structs and methods instead. let login_schema = LoginSchema { login: "user@example.com".to_string(), password: "Correct-Horse-Battery-Staple".to_string(), ..Default::default() }; // Each user connects to the Gateway. The Gateway connection lives on a separate thread. Depending on // the runtime feature you choose, this can potentially take advantage of all of your computers' threads. let user = instance .login_account(login_schema) .await .expect("An error occurred during the login process"); dbg!(user.belongs_to); dbg!(&user.object.read().unwrap().username); ``` ## Supported Platforms All major desktop operating systems (Windows, macOS (aarch64/x86_64), Linux (aarch64/x86_64)) are supported. `wasm32-unknown-unknown` is a supported compilation target on versions `0.12.0` and up. This allows you to use Chorus in your browser, or in any other environment that supports WebAssembly. We recommend checking out the examples directory, as well as the documentation for more information. ## MSRV (Minimum Supported Rust Version) Rust **1.67.1**. This number might change at any point while Chorus is not yet at version 1.0.0. ## Development Setup Make sure that you have at least Rust 1.67.1 installed. You can check your Rust version by running `cargo --version` in your terminal. To compile for `wasm32-unknown-unknown`, you need to install the `wasm32-unknown-unknown` target. You can do this by running `rustup target add wasm32-unknown-unknown`. ### Testing In general, the tests will require you to run a local instance of the Spacebar server. You can find instructions on how to do that [here](https://docs.spacebar.chat/setup/server/). You can find a pre-configured version of the server [here](https://github.com/bitfl0wer/server). It is recommended to use the pre-configured version, as certain things like "proxy connection checking" are already disabled on this version, which otherwise might break tests. ### wasm To test for wasm, you will need to `cargo install wasm-pack`. You can then run `wasm-pack test -- --headless -- --target wasm32-unknown-unknown --features="rt, client" --no-default-features` to run the tests for wasm. ## Versioning This crate uses Semantic Versioning 2.0.0 as its versioning scheme. You can read the specification [here](https://semver.org/spec/v2.0.0.html). ## Contributing Chorus is currently missing voice support and a lot of API endpoints, many of which should be trivial to implement, ever since [we streamlined the process of doing so](https://github.com/polyphony-chat/chorus/discussions/401).
