![]() ![]() In node.js you might use npm run clean to remove temporary or generated files. In node.js you might use npm run build to run webpack, tsc, or whatever. In node.js you might use npm run benchmarks to profile your code. You can even use cargo run -example xxx to automatically run example code. In node.js you might use npm run start to run your server or executable. In Rust, it depends… You have commands for common tasks but the rest is up to you. You’ll need to have an account on crates.io and set up the authentication details but cargo will help you there. In Rust you have cargo publish.Įasy peasy. There’s a lot to Rust testing that we’ll get to in a later post. In Rust you have cargo test.Ĭargo automates the running of unit tests, integration tests, and document tests through the cargo test command. You don’t need to sudo cargo install anything. If you installed rust via rustup then these are placed in a local user directory (usually ~/.cargo/bin). In Rust you have cargo install.ĭownloading, building, and placing executables in cargo’s bin directory is handled with cargo install. ![]() This gives you four new commands: add, rm, upgrade, and set-version Installing tools globally Note: not cargo-add, just in case you come across it. In Rust you can use cargo add if you install cargo-edit first. cargo new initializes projects in a new directory. In Rust you have cargo init and cargo new.Ĭargo init will initialize the current directory. Cargo uses the Cargo.toml file to know what dependencies to download, how to run tests, and how to build your projects ( among other things). In Rust you have Cargo.toml.Ĭargo’s manifest format is toml rather than the JSON you’re used to with npm’s package.json.

When something is glossed over, we’ll add links for those looking to dive deeper. This guide tries to balance technical accuracy with readability and errs on the side of “gets the point across” vs being 100% correct. We’ll take common node.js workflows and idiomatic JavaScript and TypeScript and map them to their Rust counterparts. It’s meant to bootstrap experienced node.js users into Rust. #0 40.72 help: if you built this toolchain from source, and used `rustup toolchain link`, then you may be able to build the component with `x.This guide is not a comprehensive Rust tutorial. #0 40.72 note: this is a custom toolchain, which cannot use `rustup component add` #0 40.72 error: 'cargo' is not installed for the toolchain 'wasix' #0 40.62 rustup toolchain wasix was linked and is now available! #0 40.62 Running rustup toolchain link wasix /root/.local/share/cargo-wasix/toolchains/x86_64-unknown-linux-gnu_v.1/rust: #0 40.61 Activating rustup toolchain wasix at /root/.local/share/cargo-wasix/toolchains/x86_64-unknown-linux-gnu_v.1/rust. #0 40.61 Downloaded toolchain x86_64-unknown-linux-gnu to /root/.local/share/cargo-wasix/toolchains/x86_64-unknown-linux-gnu_v.1/rust #0 1.555 Downloading Rust toolchain from url ''. #0 0.844 Downloading sysroot from url ''. => load metadata for docker.io/library/rust:1.70-bookworm 1.5s => load build definition from Dockerfile 0.0s $ docker build -t cargo-wasix-test:latest. (Note: I would have filed this on the wasix-libc repo, but it has issues disabled.)Ĭargo wasix build fails with error 'cargo' is not installed for the toolchain 'wasix'. here, here, and here), and hence that he'd certainly agree that continued use of this name would be the wrong thing to do. I'm glad I stumbled upon this before a big announcement could be made, since I know very strong stance against using names already taken by other projects in a related space (see e.g. Given that this project is very much in the same space as your system interface, this name collision would be bound to cause a great deal of confusion once you announce more widely. At one point it was also used by the official cpython distribution. Unfortunately there is a sizable problem with the name you chose, which I have no doubt is a simple oversight: since early in 2022, WASIX has been in use for an open source project by SingleStore Labs, originally developed for their port of cpython to WASI. Hey all, first off: congratulations on putting this system interface and tooling around it together! I know how much work goes into something like this, even if you can reuse so much existing code. ![]()
