Keep in mind that you might have to refactor code slightly if Prettier formats lines in a way that the max-len rule does not approve of. Just remember to keep max-len’s options and Prettier’s printWidth option in sync. If you’d like to enforce an even stricter maximum line length policy than Prettier can provide automatically, you can enable this rule. However, there are cases where Prettier can’t do anything, such as for long strings, regular expressions and comments. Usually, Prettier takes care of following a maximum line length automatically. This rule requires special attention when writing code. (The following applies to vue/max-len as well.) If you use the "multi-line" or "multi-or-nest" option, the rule can conflict with Prettier.įor example, the "multi-line" option allows this line: This rule enforces if or when those optional curly braces should be omitted. If a block (for example after if, else, for or while) contains only one statement, JavaScript allows omitting the curly braces around that statement. In other words, if you run eslint -fix and prettier -write as separate steps. These rules are safe to use if you don’t use eslint-plugin-prettier. Note: The CLI tool only reports these as problematic if the "prettier/prettier" rule is enabled for the same file. "plugin:prettier/recommended" is probably the easiest. It doesn’t matter which approach you use. Remove them from your config or turn them off manually.(Yes, there’s both a rule called "prettier/prettier" and a config called "prettier/prettier".) Put "prettier/prettier" in your "extends".That’s eslint- plugin-prettier’s recommended config. Put "plugin:prettier/recommended" in your "extends".There are a couple of ways to turn these rules off: See the arrow-body-style and prefer-arrow-callback issue for details. These rules might cause problems if using eslint-plugin-prettier and -fix. arrow-body-style and prefer-arrow-callback If you want them, you need to explicitly specify them in your ESLint config. Some can cause problems if using eslint-plugin-prettier and -fix.įor maximum ease of use, the special rules are disabled by default (provided that you include all needed things in "extends").The CLI helper tool warns you if any of those rules are enabled, but can’t tell if anything is problematic. Some require special attention when writing code. ![]() There a few rules that eslint-config-prettier disables that actually can be enabled in some cases. But if you use multiple configuration files or overrides, you can provide several files to check: Usually you’ll have about the same rules for all files, so it is good enough to run the command on one file. In theory you need to run the tool for every single file in your project to be 100% sure that there are no conflicting rules, because ESLint supports having different rules for different files. Instead you might want to actually have your own rules after eslint-config-prettier and run the CLI helper tool to find out about problems, so you can remove conflicting rules from the config file altogether (simplifying your config). It looks like we enable the indent rule, but in reality it’s disabled thanks to the eslintConfigPrettier line below it. However, looking at the above config might feel confusing. This means that any classes in the base layer will be sorted first, followed by classes in the components layer, and then finally classes in the utilities layer.Import typescriptEslint from import eslintConfigPrettier from "eslint-config-prettier" export default At its core, all this plugin does is organize your classes in the same order that Tailwind orders them in your CSS. ![]()
