Summarize the problem
I created a webpack react boilerplate for my projects and it works fine except it cannot handle JSON files and according to webpack documentation:
⚠️ Since webpack >= v2.0.0, importing of JSON files will work by default. You might still want to use this if you use a custom file extension. See the v1.0.0 -> v2.0.0 Migration Guide for more information

Fixed using the following steps:
webpack.common.js:
json files was going through babel-loader because my regular expression for js and jsx was wrong. This is the correct regular expression:
test: /\.(js|jsx)$/,
eslintrc.js:
ignore json files:
ignorePatterns: ['**/src/**/*.json'],
It is a project composed of Vite & React & antd.
I want to handle antd theme dynamically in vite.config.ts.
I would appreciate it if you could tell me how to modify less.modifyVars value in React component.
This is the current screen.
light state /
dark state
In dark mode, the style of the select component does not work properly.
import { getThemeVariables } from 'antd/dist/theme'
...
css: {
modules: {
localsConvention: 'camelCaseOnly'
},
preprocessorOptions: {
less: {
javascriptEnabled: true,
modifyVars: {
...getThemeVariables({
dark: true // dynamic
})
}
}
}
}
}
You need to import 'antd/dist/antd.less' instead of 'antd/dist/antd.css'
Install dependency for less npm add -D less. Vite will automatically catch it.
Use the following config:
css: {
preprocessorOptions:{
less: {
modifyVars: {
'primary-color': '#1DA57A',
'heading-color': '#f00',
},
javascriptEnabled: true,
},
},
},
It's been a while, but this is works for me now:
You need to make sure you import less on demand. I use plugin vite-plugin-imp to achieve. And then getThemeVariables should be work well.
import vitePluginImp from 'vite-plugin-imp';
import { getThemeVariables } from 'antd/dist/theme';
export default defineConfig({
plugins: [
// ...
vitePluginImp({
libList: [
{
libName: 'antd',
style: (name) => `antd/es/${name}/style`,
},
],
}),
],
resolve: {
alias: [
// { find: '#', replacement: path.resolve(__dirname, 'src') },
// fix less import by: #import ~
// https://github.com/vitejs/vite/issues/2185#issuecomment-784637827
{ find: /^~/, replacement: '' },
],
},
css: {
preprocessorOptions: {
less: {
// modifyVars: { 'primary-color': '#13c2c2' },
modifyVars: getThemeVariables({
dark: true,
// compact: true,
}),
javascriptEnabled: true,
},
},
},
});
Moreover: you can get more inspiration from here: vite-react/vite.config.ts

The question is related to above issue. I tried to update webpack as mentioned in the answers on github but i am constantly getting the same error. I am using create-react-app and typescript.
Module parse failed: Unexpected token (127:33)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
| * #returns {Object} - Focus and zoom animation properties.
| */
> _generateFocusAnimationProps = () => {
| const { focusedNodeId } = this.state;
I also tried installing it directly via npm but it is not working and I am getting the same error.
Tried importing like
import { Graph } from "react-d3-graph/src/index";
import { Graph } from "react-d3-graph/src";
import { Graph } from "react-d3-graph";
does not work so I am pretty much sure that the issue is with web pack any help is appreciated.

Elaborating my comment. You could do this
Clone the repo to your local file system.
Run the repo's build commands to generate a build. You'll need to see the building instructions from the repo itself. Usually available in README.md or CONTRIBUTING.md.
Then, use either use npm link or npm install to reference the locally built package.
