Dilettantes-Guide-to-Linting VS eslint-plugin-prettier

As discussed, Prettier doesn't let us do a whole lot of configuration. We only needed to change two options to match AirBnB, but we can customize a few more if we want. My Prettier config file specifies all the options I'm opinionated about, even though I'm just re-stating the default behavior for most of them.

This article is a step-by-step, ground-up look at how the most popular Javascript linting tools can be used together to professionalize any codebase. The target audience is a beginner++ level; you've written some javascript code in your IDE and probably pushed it to GitHub, but you haven't necessarily worked with other developers or published any public projects. The coverage will focus on vanilla Javascript, but some React linting is included incidentally. A TLDR version is available for more experienced developers.

You can also add ESLint now (props to @femincan for the suggestion). It comes with recommended settings for these plugins: typescript, prettier, react, react-hooks, jsx-a11y.

I recommend installing and configuring the eslint-plugin-prettier package in your project: https://github.com/prettier/eslint-plugin-prettier

eslint-plugin-prettier

Another approach that you can also take is a sort of "prettier as an ESLint plugin" option, such with eslint-plugin-prettier. The idea is that the developer only needs to run one tool (ESLint), but you add a plugin to ESLint that just calls prettier and converts the prettier error messages to ESLint error messages. I've worked at companies that have used this approach, and it makes setting up your editor/IDE very simple, because you've only got one tool to configure. That said, I personally don't like it because it forces you to use ESLint's "auto fix" functionality, which I find works well for formatting, but IME less well for some of the other lints.

A comprehensive set of formatting (through eslint-plugin-prettier) and linting rules, generated with Clinter. Once again, each package can easily extend the root configuration.

The eslint-config-prettier package disables all ESLint rules that might conflict with Prettier. This lets us use ESLint configurations without letting it get in the way when using Prettier. We can then use the eslint-plugin-prettier package to integrate Prettier rules into ESLint rules. Finally, we must set the Prettier rules in the ESLint configuration file. Add the following configuration to the .eslintrc file in the root directory of the application:

We run prettier through eslint, and run eslint through jest which provides parallelism. eslint also has a cache... So I'm not sure what dprint gets you over that?

I personally use eslint-plugin-prettier so Prettier formatting issues are shown in my editor and are reported when linting using ESLint.

When installing the Prettier and ESLint extensions for VSCode, formatting and linting will also work within VSCode for any files in the monorepo. Only tweak required to make this work is to configure the Prettier plugin for ESLint (see example .eslintrc.json). Otherwise Prettier and ESLint will get in each other’s way and make for a poor editing experience. To make this work, the following two settings will also need to be configured in a .vscode/settings.json configuration (see settings.json):

NOTICE: The template does not use eslint-plugin-prettier and prettier-eslint. So I recommend that running commands individually. e.g. prettier && eslint.
