simple-ssg1 VS ESLint

Today, I also reviewed and added a few tests to another project, which was a similar tool of my friend. I was a little happy when I realized that I have structured my work in an easy way for testing such as I have lots of isolated small functions. Meanwhile, my friend had to copy his main function and rewrite it to be able to test its logic. It was a little confusing at first to figure out how everything works and to find something testable, but because he was also using Node.js and Jest, it was manageable.

To set up workflow I added nodeJS.yml file that runs on any push or PR to main branch.

For my SSG tool I used Jest, because it was made for JavaScript language(language my tool is using) and pretty straightforward to use.

This week I've been setting up code formatters for my project.

I was adding a configuration option via -c or –config option, where it will accept a JSON file as config file to use the values inside instead of other options. It waseasy to plan for what and how I want to do, since it’s just about reading a file and using the variables. The hard part was figuring out how my code would be compatible with the repo I tried to add it to. I was working on this repo, and I opened an issue and filed a pull request. This static site generator tool doesn’t use any options but accept arguments directly, so I had to use minimist package to parse options. There are a few variables that aren’t listed in the config module, such as stylesheet url, so I added them and use the variables from the config module instead. I also ended up slightly rewriting the language option code so the program would actually use the code from the author. Overall, there where bits and pieces of code for other options that aren’t entirely functional as options, so I ended up rewriting them a bit for the configuration option to work.

Today I have been adding some features to the tool:

I created SSG tool that allows you to conver txt files into html. I was unable to fix some issues yet, but planning to make it better in the future. (https://github.com/mnosov622/simple-ssg1).

I have an issue with the location of the script. When person clones the project, and then runs it, the tool gives weird error, saying that he can't find the location of the specified txt file. ( https://github.com/mnosov622/simple-ssg1/issues/2 )

Repository: ESLint

For ESLint + TypeScript ESLint, with the new flat config eslint.config.js:

ESLint: JavaScript linting.

But what is a symbolic link exactly? It comes from programming and I often liken symbolic links to basic redirects but with greater stability. However, not every package needs a place in .bin. Packages like nodemon, webpack, gulp, eslint and create-vue are found in .bin because they need to be executed. On the other hand, packages like animate.css, swiper and express operate at the application layer, so you won't find them in .bin after installation. How does npm determine whether a package is executable or not? It's simple: by using the bin property in your package.json to specify the executable path. If your package is executable, you can set it accordingly. Let's take a look at prettier's package.json file

Eslint: It analyzes our code to quickly find problems. We will use the default setup provided by Vite.

A big part of my work revolves around JavaScript tooling, and as such it's important to keep an eye on the ecosystem and see where things are going. It's no secret that recently lots of projects are native-ying (??) parts of their codebase, or even rewriting them to native languages altogether. Esbuild is one of the first popular and successful examples of this, which was written in Go. Other examples are Rspack and Turbopack, which are both Rust-based alternatives to Webpack, powered by SWC ("Speedy Web Compiler"). There's also Rolldown, a Rust-based alternative to Rollup powered by OXC ("The JavaScript Oxidation Compiler"), but Rollup itself is also native-ying (??) parts of their codebase and recently started using SWC for parts of their codebase. And finally, there are Oxlint (powered by OXC) and Biome as Rust-based alternatives for Eslint and Prettier respectively.

Let's be honest - setting up tools for a new project can be a frustrating process. Especially when you want to jump straight to coding part. This is often the case with ESLint and Prettier, two popular tools in the JavaScript ecosystem that can sometimes interfere with each other when it comes to code formatting. Fortunately, there's a simple solution to this process, and it's called eslint-plugin-prettier.

Do you have the need to find and fix problems in your JavaScript? Then ESLint is for you. With over 120 million downloads each month, it's definitely one of the most popular projects out there. The latest version introduces a new configuration system, designed to simplify available configuration options. Old and deprecated rules have been removed, and a new configuration inspector has been added. Check out the blog for all the highlights, and a migration guide.

ESLint: A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript.

Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.
