Blitz

**A [radically modular](https://github.com/DioxusLabs/blitz?tab=readme-ov-file#architecture) HTML/CSS rendering engine** [![Build Status](https://github.com/dioxuslabs/blitz/actions/workflows/ci.yml/badge.svg)](https://github.com/dioxuslabs/blitz/actions) [![Crates.io](https://img.shields.io/crates/v/blitz.svg)](https://crates.io/crates/blitz) [![Docs](https://docs.rs/blitz/badge.svg)](https://docs.rs/blitz) [![Crates.io License](https://img.shields.io/crates/l/blitz)](#license) [![dependency status](https://deps.rs/repo/github/dioxuslabs/blitz/status.svg)](https://deps.rs/repo/github/dioxuslabs/blitz) Talk to us in: the [#native](https://discord.gg/AnNPqT95pu) channel in the [Dioxus Discord](https://discord.gg/AnNPqT95pu) ## Status Blitz is currently in a **pre-alpha** state. It already has a very capable renderer, but there are also still many bugs and missing features. We are actively working on bringing it into a usable state but we would not yet recommend building apps with it. Check out the [roadmap issue](https://github.com/DioxusLabs/blitz/issues/119) for more details. ## Screenshot ![screenshot](https://raw.githubusercontent.com/DioxusLabs/screenshots/main/blitz/counter-example.png) > Note: This repo contains a new version of Blitz (v0.2+) which uses Stylo. The source code for the old version (v0.1) is still available on the [legacy](https://github.com/DioxusLabs/blitz/tree/legacy) branch but is not under active development. ## Trying it out 1. Clone this repo 2. Run our "browser" package: ```sh cargo run --release --package browser ``` 3. Or run an example: - small TODO app ```sh cargo run --release --package todomvc ``` - markdown renderer ```sh cargo run --release --package readme ./README.md ``` - integration with raw WGPU rendering ```sh cargo run --release --package wgpu_texture ``` Other examples are available in the [examples/](./examples/) folder. ## Goals Blitz is designed to render HTML and CSS - we *don't* want to support the entirety of browser features (or at least we want to make all such "extra" features opt-in). In our opinion, the browser is bloated for the basic use case of rendering HTML/CSS. We do intend to support: - Modern HTML layout (flexbox, grid, table, block, inline, absolute/fixed, etc). - Advanced CSS (complex selectors, media queries, css variables) - HTML Form controls - Accessibility using AccessKit - Extensibility via custom widgets Notably we *don't* provide features like webrtc, websockets, bluetooth, localstorage, etc. In a native app, much of this functionality can be fulfilled using regular Rust crates and doesn't need to be coupled with the renderer. We don't yet have Blitz bindings for other languages (JavaScript, Python, etc) but would accept contributions along those lines. ## Architecture Blitz consists of a core DOM abstraction; several modular pieces which provide additional functionality like networking, rendering, windows, and state management; and two high-level wrappers that support rendering either a Dioxus application or HTML with a simplified API. These pieces can be combined together to make a cohesive web engine. ### High-level "wrapper" crates - **`blitz`** - An HTML/markdown frontend that can render an HTML string. This is useful for previewing HTML and/or markdown files but currently lacks interactivity.
Uses: `blitz-dom`, `blitz-html`, `blitz-shell`, `blitz-renderer-vello` - **`dioxus-native`** - A Dioxus frontend that can render a Dioxus VirtualDom. This has full interactivity support via Dioxus's event handling.
Uses: `blitz-dom`, `dioxus-core`, `blitz-shell`, `blitz-renderer-vello` Both wrappers can optionally use `blitz-net` to fetch sub-resources. ### Using the git verison of Dioxus Native The latest development version of the Dioxus Native lives in this repository. As Dioxus Native is under rapid development it can be useful to use this version to get access to the latest features and bug fixes sooner than they are available in an official release. To use the git version of `dioxus-native`: - Remove your dependency on the `dioxus` crate entirely. - Add `dioxus-native = { git = "https://github.com/DioxusLabs/blitz", rev = "e64a3d8", features = ["prelude"] }` - (replace `e64a3d8` with the git commit id of the version you want to use) - In your rust code change all instances of `use dioxus::prelude::*` to `use dioxus_native::prelude::*`. - If you need to access additonal functionality from the `dioxus` crate that is not exported from the Dioxus Native prelude then you can import it from the individual sub-crates (`dioxus-html`, `dioxus-signals`, `dioxus-router`, etc) instead. The git versions of Dioxus Native still depend on the stable v0.7.x version of Dioxus from crates.io, so any additional libraries that you are using (`dioxus-sdk`, `dioxus-components`, `dioxus-free-icons`, etc) should still work. ### Modular Components #### Core crates - **`blitz-dom`** - The core DOM abstraction that includes style resolution, layout and event handling (but not parsing, rendering or system integration).
Uses: [Stylo](https://github.com/servo/stylo) (CSS parsing/resolution), [Taffy](https://github.com/DioxusLabs/taffy) (box-level layout), [Parley](https://github.com/linebender/parley) (text layout) - **`blitz-traits`** - Minimal base crate containing types and traits to allow the other crates to interoperate without depending on each other #### Additional crates - **`blitz-net`** - Networking that can fetch resources over http, from the file-system or from encoded data URIs.
Uses: [reqwest](https://github.com/seanmonstar/reqwest) (HTTP client) - **`blitz-paint`** - Translates a `blitz-dom` tree into `anyrender` draw commands.
Uses: [anyrender](https://github.com/dioxuslabs/anyrender) (2D drawing abstraction) - **`blitz-html`** - Adds HTML parsing to `blitz-dom`
Uses: [html5ever](https://github.com/servo/html5ever) (HTML parsing) and [xml5ever](https://github.com/servo/html5ever/tree/main/xml5ever) (XHTML parsing) - **`blitz-shell`** - A shell that allows Blitz to render to a window (integrates a Winit event loop, AccessKit, Muda etc).
Uses: [winit](https://github.com/rust-windowing/winit) (windowing/input), [accesskit](https://github.com/AccessKit/accesskit) (accessibility), [muda](https://github.com/tauri-apps/muda) (system menus) The AnyRender rendering abstraction now lives in it's repository over at https://github.com/dioxuslabs/anyrender ## License This project is dual licensed under the Apache 2.0 and MIT licenses.
