eslintrc.js and make the contents of the file simply: module.exports = Let’s add a file at the root of our project (probably where your package.json is) called. To support ESLint, we’ll need to do one more thing. If you're working with a large project with many file types, maybe even some you don't want linted, you can change that flag or be more specific with other options. In the above, we’re running our linter on the entire project directory on any file that has an extension of. After it’s successfully installed, let’s add it to our package.json as a script. We’re installing this as a devDependency (hence the -D flag), because this isn’t something our application needs to run. Let’s first add our ESLint dependency: yarn add eslint -D ESLint is available as an npm package by itself and once installed, out of the box it allows you to set up a basic configuration file and hit the ground running with some command line tools. Your linter will actually be the engine for defining rules and parsing your files to test against.
Probably the most popular in the Javascript world is ESLint. You can easily follow along by spinning up your own React app or using my Gatsby starter: Your Linter I’m going to run through how you can get set up for basic linting in a React app. The same principles apply, but the tooling may be a bit different. So how do I actually get started?Įven though there are linters for most, if not all, other mainstream languages, for the purpose of this post, I’m going to focus on Javascript. They add up and end up taking away the time you can spend fixing another bug or developing the next great feature of your product. Grandma looking for a semicolonĪll of those moments that stop you from being productive because of a silly syntax error or the micro-interactions you and your teammates have during a review take time. No longer will you and your reviewer endlessly fight passive aggressively through the comments about whether or not to include a semicolon at the end of JS statements ( you should ?).
WHAT IS ANOTHER WORD FOR SAVING CODE
No longer will these issues creep up on you in the middle of running your app or give someone anxiety during a code review. Probably the biggest overlying theme of the list above is the fact that these issues will be called out immediately. Most things you can think of probably already exist in one form or another, and if not, you can even create custom rules that fit your needs! How is this actually helping or why should I care? Providing suggestions for common best practices.
