Draco
Draco is a Rust library for building client side web applications with Web Assembly.
Draco implements a Redux and Elm inspired architecture. The core of a Draco application consists of two functions:
render
: returns a description of what should be rendered on the screen. This description is efficiently applied to the browser's DOM with a minimal number of patches using Virtual DOM diffing.update
: receives a message and updates the state of the application. The application is re-rendered after every update.
Getting Started
There's a starter crate available here.
To run it, clone the repository:
$ git clone https://github.com/utkarshkukreti/draco-starter
$ cd draco-starter
and follow the instructions in its README.
Examples
There's not a lot of documentation present right now. If you want to learn more, the best way is to read the source code of the examples.
We recommend starting with Hello World, followed by Counter, and then Counters.
To build the examples, you'll need Ruby and wasm-bindgen-cli installed.
$ cd /path/to/this/repo
$ rake
Now start an HTTP server of your choice 1 and open
target/examples/index.html
in your browser to run the examples.
[1] Python 2/3's built in HTTP Server (and
possibly others) does not work as browsers require .wasm
files to be served
with a MIME type of application/wasm
which they do not do. Try
serve if your HTTP server of choice
does not work.
