Stylelint can format your CSS with -fix switch, check the Linting chapter to know how to set it up. To solve this issue you can disable prettier/prettier rule in your editor’s ESLint settings. If you have ESLint in your editor, you may notice that it reports too many issues while you’re writing code because of Prettier. You can set up your editor to run eslint -fix on save and it will reformat your code every time you save a file. You can also put your Prettier config into a. editorconfig root = true indent_style = tab end_of_line = lf charset = utf-8 trim_trailing_whitespace = true insert_final_newline = true [*. editorconfig) with separate rules for Markdown, JSON and YAML files:

This is handy when developers use platforms with different line endings, e.g., Mac and Windows. This way your editor can automatically choose the correct settings. Configuring IDEs and Editors With EditorConfig #ĮditorConfig allows you to define indentation style and other whitespace settings for any file type. Most of the time you’ll benefit from using both tools at the same time: use ESLint to catch possible errors and achieve consistent language usage and Prettier to format the code. ESLint can fix indentation, semicolons or quote type in JavaScript, but Prettier can achieve 100% code consistency, because it removes the original formatting and reprints all the code using its own formatting rules. To detect such issues you’ll have to review all new code manually.Ī common misconception is that if you use a code formatter like Prettier then you don’t need a linter anymore. For example, you could have FooLoader and BarThatLoadsFoo that both do the same thing but in different ways. Problems like naming consistency are hard, or even impossible, to detect automatically.

const / let can be detected by ESLint, but higher level patterns can’t.

Linters can help with the second problem, although they won’t solve it entirely. They also solve another problem - arguments on the right code style in a team.

programming patterns used consistently across the codebase Ĭode formatting tools solve the first problem.

Achieving Code Consistency #Ĭode consistency helps when several people work on the same codebase: I think that this is a well-rounded solution for most projects, but if you would like to change the files that get formatted, you can adjust the -pattern parameter by following the minipatch pattern.Usually linters can validate and fix code formatting but there are specialized tools that work better. This will automatically run Prettier against your staged files that are within the src/ folder that match one of the extensions js, jsx, ts, tsx, json, css, scss, md, or html. You can add single configurations to this file, such as '" To customize the Prettier configuration, you can add a. This allows you to experiment with JavaScript and see how Prettier would format the code in real-time, and if you find a set of options that you prefer, then you can copy the proper config to your clipboard. The Prettier team offers a useful tool on their website called Prettier Playground. I have also been on teams in the past that attempted to adopt code formatting guidelines, but the endless debates over which options were better prevented us from ever making a final decision. I have used code formatting tools that have well over 100 options, while Prettier only has about 16. In this case, "opinionated" means that Prettier has a prescribed way of formatting code, with only a handful of options that you can configure. Prettier describes itself as an opinionated code formatter. Perhaps more importantly, consistent formatting across a collaborative codebase can make the development experience less frustrating as the developer knows what to expect of their own contributions. Well placed tabs, brackets, and newlines can make it much easier for a developer to read and understand code. Quality grammar can make a written body of work more appealing to read, and easier to digest, and code formatting can do the same for a project's source code.

Code formatting is not a new concept, but based on my experience with professional software development, it's a problem that many companies and projects still struggle with.
