React Project Organization & ESLint Setup Part 3 | Configuring Folder Aliases, ESLint
Welcome back to Code Caty! In this third part of our React project setup series, we’ll enhance your project configuration by setting up folder aliases. This will simplify your imports and integrate seamlessly with your ESLint and Vite configurations. Here’s what we’ll cover:
Learn how to add and use folder aliases in your `tsconfig.json` or `jsconfig.json` file. We’ll set up paths such as `@components` and `@atoms` to make your imports cleaner and more manageable.
Discover how to configure ESLint to recognize and properly resolve these folder aliases. We’ll use `eslint-import-resolver-typescript` or `eslint-import-resolver-alias` to ensure linting works smoothly with your new alias setup.
Vite Configuration: Set up Vite to support your folder aliases using the `path` module. We’ll guide you through updating your `vite.config.js` file to handle these aliases effectively.
NOTE:
If you’re using TypeScript, configure folder aliases in your `tsconfig.json` file. For example:
```{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/*": ["src/*"],
"@components/*": ["src/components/*"],
"@atoms/*": ["src/components/atoms/*"]
}
}
}
```
For TypeScript projects, you'll also need to ensure ESLint recognizes these paths using `eslint-import-resolver-typescript` and configure Vite with the `path` module.
If you’re using JavaScript:
1. Create a `jsconfig.json` file** at the root of your project to configure folder aliases similarly to TypeScript:
```json
{
"compilerOptions": {
"baseUrl": ".",
"paths": {
"@/*": ["src/*"],
"@components/*": ["src/components/*"],
"@atoms/*": ["src/components/atoms/*"]
}
}
}
```
2. Configure Vite to handle the aliases by updating your `vite.config.js` file. Use the `path` module to define your aliases:
```javascript
import path from 'path';
import react from '@vitejs/plugin-react';
import { defineConfig } from 'vite';
export default defineConfig({
plugins: [react()],
resolve: {
alias: {
'@': path.resolve(__dirname, './src'),
'@components': path.resolve(__dirname, './src/components'),
'@atoms': path.resolve(__dirname, './src/components/atoms'),
},
},
});
```
3. Update ESLint Configuration: For JavaScript projects, use `eslint-import-resolver-alias` to configure your aliases. Add the following to your `.eslintrc` file or ESLint configuration file:
```json
{
"settings": {
"import/resolver": {
"alias": [
["@", "./src"],
["@components", "./src/components"],
["@atoms", "./src/components/atoms"]
]
}
}
}
```
By following these steps, you’ll ensure that both your development environment and linting tools correctly recognize and handle folder aliases, whether you're using TypeScript or JavaScript.
