To override Ant Design's Less variables in a Vite.js + React project, you need to set up a custom Less configuration to modify the theme variables. Vite.js allows you to use plugins to customize the build process. We can use the vite-plugin-theme to override Ant Design's Less variables.

Here are the steps to achieve this:

  1. Install Dependencies: First, make sure you have installed the necessary dependencies.
bash
npm install antd vite-plugin-theme --save-dev
  1. Create a Custom Theme File: Create a new Less file (e.g., custom-theme.less) in your project and override the Ant Design Less variables you want to modify. For example:
less
// custom-theme.less @primary-color: #1890ff; @link-color: #1890ff; // Add more variable overrides as needed
  1. Create a Vite Config File: Create a vite.config.js file in the root of your project with the following content:
javascript
// vite.config.js import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react'; import themePlugin from 'vite-plugin-theme'; export default defineConfig({ plugins: [ react(), themePlugin({ // Path to your custom theme file theme: './custom-theme.less', }), ], });
  1. Import Ant Design Less Styles: In your main entry file (e.g., index.js or App.js), import Ant Design's Less styles using the following:
javascript
// index.js or App.js import 'antd/dist/antd.less'; import './custom-theme.less'; // Import your custom theme file
  1. Use Ant Design Components: Now you can use Ant Design components in your React application, and they will be styled using the variables defined in your custom theme.

When you run your Vite development server, the vite-plugin-theme will process the custom-theme.less file and apply the overridden variables to the Ant Design styles. This way, you can easily customize the look and feel of your Ant Design components.

Remember to adjust the variable overrides in custom-theme.less according to your preferences. You can refer to Ant Design's documentation for a list of available Less variables that you can customize.

Note: If you encounter any issues or conflicts with styles, double-check that you have imported the styles correctly and that there are no errors in your Less theme file.
