language-tools VS lint-staged

I don't use nvchad, I use vanilla neovim with mason + lspconfig, but in the issues section there is a hint https://github.com/sveltejs/language-tools/issues/2008

I've opened an issue on the sveltejs repo on GitHub (there's more info there, like steps to reproduce) and haven't got any answers yet, so I'm hoping I'll have better luck here, maybe someone has faced this before.

It was a bit hard to understand but after reading this issue, it worked for me like this:

Hi. I just got into Svelte today and I was wondering about the Svelte LSP's features. I found this issue https://github.com/sveltejs/language-tools/issues/83, which indicates that "extract into const/function/component refactorings" code actions are already implemented for the Svelte LSP.

However, the Svelte Language Tools does leverage JSX for type checking via svelte2tsx.

Not yet, but there’s an open issue: https://github.com/sveltejs/language-tools/issues/1326

svelte-check: check only files mentioned as arguments #353

Lint Staged: https://github.com/lint-staged/lint-staged

lint-staged is the second important tools we need here, install it via NPM.

We were already using lint-staged and have a pre-commit hook in place using Husky in our project for linter and prettier. So it made sense to add a check here.

Now you can config it in your package.json, here is the guide doc:

In the world of software development, maintaining consistent code quality and ensuring that the codebase adheres to predefined patterns and guidelines is crucial. However, manually enforcing these standards can be time-consuming and error-prone. This is where automation tools like Husky, Lint-Staged, Commitlint, and Commitizen come to the rescue. In this post, we will explore how these tools can be combined to streamline your development workflow.

This is wasted work that can and should be automated. Adding a linter and formatter on CI and a pre-commit hook such as lint-staged can do wonders.

lint-staged is a package that can be used to run formatting and linting commands on staged files in a Git repo.

To answer your next question: I lint and format on save, and I use Git hooks installed by Husky and executed through Lint-Staged (this tool helps ensure your Git hooks only run on modified files, etc) to ensure there are no lint or formatting errors whenever making a commit or pushing code. This is helpful for teams, as some developers tend to forget to run lint tasks, or don't have the Prettier extension installed in their IDE. If there are lint errors, the commit is rejected until fixed. YMMV - you'll need to fine-tune the strictness of this based on the team's needs.

Uses Husky Git hooks and Lint-staged pre-commit hooks.

Something else to consider is applying linting and formatting before every git commit. A package like Lint-staged only lints and formats on staged items, ensuring all pushed code follows the standards in the repo. This allows developers to have their own formatting preferences when developing, while the code homogenizes on push. Linting pre-commit also avoids strict rules like no-console or no-unused-vars restricting a developer when writing code, when it should only apply in production. Imagine not being able to console log anything during development!
