## Introduction
Tauri is a framework for building tiny, blazing fast binaries for all major desktop platforms. Developers can integrate any front-end framework that compiles to HTML, JS and CSS for building their user interface. The backend of the application is a rust-sourced binary with an API that the front-end can interact with.

The user interface in Tauri apps currently leverages Cocoa/WebKit on macOS, gtk-webkit2 on Linux and MSHTML (IE10/11) or Webkit via Edge on Windows. **Tauri** uses (and contributes to) the MIT licensed project that you can find at [webview](https://github.com/webview/webview) and the [related webview organization](https://github.com/webview).


## Get Started
If you are interested in making a tauri-app, please visit the [documentation website](https://tauri.studio).

#### Notes

## Development

Tauri is a system composed of a number of moving pieces:

### Infrastructure
- git for code management
- github for project management
- github actions for CI and CD
- discord for discussions
- netlify-hosted documentation website

### Major Runtimes
- node.js for running the CLI (deno and pure rust are on the roadmap)
- cargo for testing, running the dev service, building binaries and as the runtime harness for the webview

### Major Languages
- typescript for the CLI
- javascript for the JS-side of the API
- rust for bindings, rust side of the API, harnesses
- C / obj-c for interfacing with the webviews

### Operating systems
Tauri core can be developed on Mac, Linux and Windows, but you are encouraged to use the latest possible operating systems and build tools for your OS.

### Contribution Flow
Before you start working on something, it is best to check if there is an existing issue first. Also it is a good idea to stop by the Discord guild and confirm with the team if it makes sense or if someone is already working on it. If you want to read more about this, please see [this page](https://github.com/tauri-apps/tauri/blob/dev/.github/CONTRIBUTING.md).

### Documentation
Documentation in a polyglot system is a tricky proposition. To this end, we prefer to use inline documentation of Rust code and at JSDoc in typescript / javascript code. We autocollect these and publish them using Docusaurus v2 and netlify. Here is the hosting repository for the documentation site: https://github.com/tauri-apps/tauri-docs

### Testing & Linting
Test all the things! We have a number of test suites, but are always looking to improve our coverage:
- Rust (`cargo test`) => sourced via inline `#[cfg(test)]` declarations
- TS (`jest`) => via spec files
- Smoke Tests (run on merges to latest)
- eslint, clippy

### CI/CD
We recommend you read this article to understand better how we run our pipelines: https://www.jacobbolda.com/setting-up-ci-and-cd-for-tauri/

## Organization
Tauri aims to be a sustainable collective based on principles that guide [sustainable
free and open software communities](https://sfosc.org). You can get involved in many ways.

This has been done with our best attempt at due diligence and in
respect of the original authors. Thankyou - this project would never have
been possible without your amazing contribution to open-source and we are
honoured to carry the torch further. Of special note:
- [zserge](https://github.com/zserge) for the original webview approach and
go bindings
- [Burtonago](https://github.com/burtonageo) for the Cargo Bundle prototype

## Contributing
Please make sure to read the [Contributing Guide](./.github/CONTRIBUTING.md)
before making a pull request.

Thank you to all the people who already contributed to Tauri!

Special thanks to the development team at Volentix Labs for the encouragement and support in the early phases of Tauri, notably Rhys Parry and Gregory Luneau.
