Git Project Configuration With Husky and 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.

Six Factors That Raise The Risk Of Bugs In A Codebase
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.

Why it is Important to Update Linters and How to Do it Right
All modern linters incorporate functionality for extending configurations, although the syntax for this is often implemented differently. Taking ESLint as an example, in its latest versions, the primary extension method is through the use of the spread operator. Let's take a look at an example:

How Automation Saved Me from Oops Moments: Never Skip Tests in Production Again!
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.

Automating code patterns with Husky
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.

Set up linting and formatting for code and (S)CSS files in a Next.js project
lint-staged is a package that can be used to run formatting and linting commands on staged files in a Git repo.

How do you handle eslint/prettier configs across multiple repos?
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.

How to Contribute on the First Day of a Frontend Project
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!

How to beautify your code and make contributions easy?
Additionally, there are pre-commit hooks which can be setup to seamlessly validate and modify the source code before every commit. I followed Prettier documentation to create one. I ran npx mrm@2 lint-staged which installed husky and lint-stagedand added a configuration to the project’s package.json. Then, I modified the commands a little and that's it.

Just deployed my first web app. I know it's simple, but any feedback would be greatly appreciated..
I'm noticing a lack of formatting in your JS. Some files have semi-colons, some don't. Some lines are indented more than others. There's inconsistent use of single vs double quotes. You can easily standardize formatting with a Prettier. It's recommend to run it with husky and lint-staged on every commit so you never commit code which is unformatted. (Same with your HTML and CSS which are inconsistently formatted making it harder to read.)
