eslint-config-prettier VS prettier-eslint

As I was reading the Prettier documentation I stumbled upon this blob which talks about how to make ESLint and Prettier play nicely with each other. It instructed to install eslint-config-prettier dependency in my project using the command npm install --save-dev eslint-config-prettier. Then I added prettier as part of the .eslintrc.cjs' extends array making prettier dependency part of the linting process. Lastly, I ran its cmd line helper npx eslint-config-prettier path/to/main.js to check if there were any ESLint rules which are unnecessary or would conflict with Prettier. The test results came out fine with no unnecessary or conflicting rules. The use case on how it works and why to use it is mentioned here.

I wouldn’t say they’re arguing something completely different. A large subset of linting rules are by nature purely formatting rules. You can enforce line length with either prettier or a linter and both can auto fix the issue.

Because of this things like [`eslint-config-prettier`](https://github.com/prettier/eslint-config-prettier) exist to ensure conflicting eslint formatting rules are disabled if they can be handled by prettier.

Also add this eslint plugin, which makes eslint play nice with prettier: https://github.com/prettier/eslint-config-prettier

Linting is an important step in maintaining code quality, The React Library Builder uses ESLint and eslint-config-prettier for linting. You can modify linting rules by overriding them in the .eslintrc file.

eslint-config-prettier: An ESLint configuration which disables the formatting rules in ESLint that Prettier is going to be responsible for handling, hence avoiding any clashes.

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:

eslint-config-prettier:

To automatically disable all ESLint rules that conflict with prettier you can use eslint-config-prettier as follows:

Some of the ESLint rules Next.js comes pre-configured with are about formatting. But we want Prettier to handle everything related to the formatting of our code. This is why we'll install eslint-config-prettier and add it to our .eslintrc, where it will disable all existing rules that might interfere with Prettier.

Now since some prettier configs may conflict with ESLint, we need to turn off conflicting rules. This can easily be done by adding eslint-config-prettier:

prettier-eslint

And I just ripped out my prettierrc/prettier recently, and still need some tweaking in this area, and might even add it it back. After looking at that plugin, it looks like it just DISABLES things in ESLint that Prettier handles, so you might have to add the prettier script and a .prettierrc config file. At least that is how I understand it. I was just looking at prettier's docs and saw this though - https://github.com/prettier/prettier-eslint, which seems like it might be what you are looking for.
