vue files, as well as Vue code contained in. This plugin allows us to lint the and sections of. You can find some of these shared configs on by searching for “eslint-config” (the naming convention for shared configs).ĮSLint has a pluggable architecture that enables creating plugins, which can add extra capabilities to ESLint, and gives a new baseline to add your own custom rules.Īn example of this is eslint-plugin-vue, which is the official plugin for Vue.js. Many people have done the heavy lifting for you by creating shareable configs, which have rulesets for popular JavaScript frameworks and common style guides/coding standards such as Google’s JavaScript Style Guide. ESLint has built-in rules that make it useful from the start, but you can add rules specific to your project and whatever flavor of JavaScript you use. The primary reason ESLint was created was to allow developers to create their own linting rules. However, ESLint enables developers to discover problems with their code without actually executing their code. Without the benefit of a compilation process, JavaScript code typically executes to find syntax or other errors. Since JavaScript is a dynamic and loosely-typed language, it is especially prone to developer errors. Linting is a type of static analysis that finds problematic patterns and code that doesn’t adhere to certain style guidelines. What is ESLint?ĮSLint is a JavaScript linting utility that was first released in June 2013 and now is by far the number one linting utility. The bottom line is that the development team intends to never add more options from now on you can read more about this in Prettier’s Option Philosophy. A few were added during Prettier’s infancy to entice more people into using it, a couple of options were added due to demand, and some rules were added for compatibility reasons. While a big reason to use Prettier is to avoid configuration altogether, Prettier does support its own configuration file that has a handful of formatting options. Even if Prettier does not format your code 100% the way you like, it’s worth the sacrifice for the simplicity of the approach. The idea is that Prettier’s style guide is fully automatic. The primary reason Prettier was created was to eliminate debates over code styles. This rewriting process prevents developers from introducing any formatting mistakes. Prettier enforces a consistent format by parsing code and reprinting it with its own rules that take the maximum line length into account, wrapping code when necessary. Prettier is an opinionated code formatter for JavaScript and other popular languages.
