RSLint VS deno_lint

RDambrosio016/RSLint (Rust): A (WIP) Extremely fast JavaScript linter and Rust crate

RDambrosio016 / RSLint

Fast compilation seems very appealing. It is one of the main reason why I am interested into Go and Zig.

I recently started working with Rust for contributing to projects like Rome/tools [1] and deno_lint [2]. The compilation and IDE experience is frustrating. Compilation is slow. I am afraid that this is rooted to the inherent complexity of Rust.

Though, for large scale projects, I’d wait until https://github.com/denoland/deno_lint/issues/303 is done; if they tackle that, they tackled types, and that’s the single big thing yet to tackle.

There isn't any uniformity that could be reasonably achieved once plugins are added to a linter. Someone will always want an edge case for their project covered even if it's not in the uniform configuration; most large projects either use plugins or custom rules outside of what ESLint provides. Deno understands this too given that plugin support is being considered.

Deno's lint config is under deno.json or deno.jsonc and is limited to the following rules: https://lint.deno.land/

I built one of the tools mentioned in the article, Deno's linter. Its binary is over 30 MiB:

After a long time, I started contributing to open-source software. For a long time, I had my eye on Deno. This week, I merged my first PR in Deno Lint. Following is the detailed post about the issue.
