ESLint VS berry

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.

If you're a developer, you're surely familiar with Prettier and ESLint. With over 8 years of existence, they have established themselves as references in the JavaScript ecosystem.

eslint is used to avoid code errors

No lint errors: The committed code does not contain any lint errors (eslint).

Let’s walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.

ESLint

1. Lack of Static Code Analysis Static code analysis tools like TypeScript and ESLint play a crucial role in identifying and preventing bugs. TypeScript provides static typing, enhancing the robustness of the code. ESLint detects issues and enforces coding standards. The absence of these tools can significantly elevate the likelihood of bugs due to the lack of early detection and guidance provided during development.

Latest version of Node and Yarn

Have Node and Yarn installed with a recent version.

Node.js manages dependencies using package managers like npm (Node Package Manager), yarn, and pnpm. npm comes pre-installed with Node.js and allows you to install and uninstall Node.js packages. It uses a package.json file to keep track of which packages your project depends on. Yarn and Pnpm are alternative package managers that aim to improve on npm in various ways, such as improved performance and better lock file format.

Depending on the stack of the repository you are cloning, you might have to install additional dependencies. For this demo, I'm using my own website, which is a static website built with Astro.js. It which requires to have Node.js installed and Yarn for package manager.

A package manager such as npm, Yarn, or pnpm. A package manager is a tool that helps you manage the dependencies of your project. You can use any of these package managers to install Jest and other packages.

To start off, you'll need Node.js installed on your local system. This ChatGPT API guide will use Yarn to install dependencies in the project, but you're free to use npm or any other package management tool if you wish. Finally, you'll need an OpenAI account for ChatGPT API access.

This package is available in the Node Package Repository and can be easily installed with npm or yarn

Yarn or Npm(This tutorial uses Yarn)

However, the easiest way to install the Snyk CLI for your JavaScript application is to do so using the npm or Yarn global installation since you most likely already have Node.js installed. Ensure you're using Node.js version 12 or later and run the following command to install the Snyk CLI as a global npm package:
