This cargo subcommand aims to make it easy and convenient to build, develop and deploy client-side Web applications written in Rust.
It's currently very early in development; for now it supports the following sub-subcommands:
cargo web build
- builds your projectcargo web test [--nodejs]
- automatically runs your tests in a web browser (experimental) or under Nodejscargo web start
- builds the project, starts an embedded webserver and rebuilds as needed
It supports all three of Rust's Web backends when passed one of the following parameters:
--target-asmjs-emscripten
- builds forasmjs-unknown-emscripten
(default)--target-webasm-emscripten
- builds forwasm32-unknown-emscripten
--target-webasm
- builds for Rust's nativewasm32-unknown-unknown
, requires Rust nightly
Before compiling anything you will have to install the corresponding targets
with rustup
yourself, e.g.:
$ rustup target add asmjs-unknown-emscripten
On i686 and x86_64 Linux it will also automatically download Emscripten for you
when building for the *-emscripten
targets.
It's also highly recommended that you check out the stdweb crate if you want to interact with the JavaScript world in your project.
Other features which are (eventually) planned but are yet not here:
- Fully headless test running.
- Feature parity with cargo.
- Built-in minification.
- Possibly a bridge into the
npm
ecosystem to fetch JavaScript libraries. - Anything else you might expect from a tool like this (suggestions welcome!).
$ cargo install cargo-web
To upgrade:
$ cargo install --force cargo-web
Or clone and build with $ cargo build --release
then place in your $PATH.
