Integrating ESLint with Prettier in a TypeScript Next.js Project - Code Review Troubles
Quick question that's been bugging me - I'm deploying to production and I'm sure I'm missing something obvious here, but I'm sure I'm missing something obvious here, but During development, our team is striving to maintain a clean and consistent code style across our Next.js application that uses TypeScript... We've decided to integrate ESLint and Prettier to enforce best practices and streamline our code review process. However, we're running into some configuration headaches that are causing linting errors. Initially, I set up ESLint with the following configuration in `.eslintrc.js`: ```javascript module.exports = { parser: '@typescript-eslint/parser', extends: [ 'plugin:react/recommended', 'plugin:@typescript-eslint/recommended', 'prettier' ], plugins: ['react', '@typescript-eslint'], rules: { 'react/react-in-jsx-scope': 'off', }, }; ``` Next, I integrated Prettier with a `.prettierrc` file: ```json { "semi": true, "singleQuote": true, "trailingComma": "all" } ``` However, when it comes to running the linter, I get multiple conflicting rules that Prettier and ESLint seem to be disagreeing on. For example, I receive warnings about line length and quotes, even though they're already defined in my Prettier settings. After trying to adjust the settings by adding `eslint-config-prettier` to my ESLint configuration to disable formatting rules, it didn't seem to resolve all the issues. Here’s what I added: ```bash npm install --save-dev eslint-config-prettier ``` Yet, I still see conflicts when I run `eslint .`. The current output shows: ``` error: Missing semicolon (semi) at ... error: Unexpected use of singlequote (quotes) at ... ``` To further troubleshoot, I followed some community recommendations but ended up with inconsistent formatting in the editor. What steps can I take to better align ESLint and Prettier to work seamlessly together in our Next.js project? Have I missed any crucial configuration that's preventing the rules from coexisting? Any insights from those who have tackled this integration successfully would be highly appreciated. For context: I'm using Javascript on macOS. My development environment is Windows. Is there a better approach? I'm coming from a different tech stack and learning Javascript. Thanks for taking the time to read this! My development environment is Ubuntu 22.04.
