I’m currently attempting to use Chart.js within my react application but when I go to build my application I’m presented with this error
ERROR in ./node_modules/chart.js/dist/chart.esm.js
Module parse failed: D:MyAppnode_moduleschart.jsdistchart.esm.js Unexpected token (6613:12)
You may need an appropriate loader to handle this file type.
| if (intermediateIndex1 !== startIndex && intermediateIndex1 !== lastIndex) {
| decimated.push({
| ...data[intermediateIndex1],
| x: avgX,
| });
@ ./src/imports/Dashboard/Dashboard.js 21:12-31
@ ./src/App.js
@ ./src/index.js
@ multi babel-polyfill ./src/index.js
I tried researching online to see if anyone else has had the same issue, but I had no luck.
Below is my Webpack config file:
const path = require('path');
module.exports = {
entry: ['babel-polyfill', './src/index.js'],
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js'
},
module: {
rules: [{
loader: 'babel-loader',
test: /.jsx?$/,
exclude: /node_modules/
}, {
test: /.s?css$/,
use: [
'style-loader',
'css-loader',
'sass-loader'
]
},{
test: /.(jpe?g|png|gif|svg|mp3)$/i,
loaders: [
'file-loader?hash=sha512&digest=hex&name=[hash].[ext]',
'image-webpack-loader?bypassOnDebug&optimizationLevel=7&interlaced=false'
]
}
]
},
devtool: 'cheap-module-eval-source-map',
devServer: {
contentBase: path.join(__dirname, 'public'),
historyApiFallback: true
}
};
And here is my bablerc file
{
"presets": [
"env",
"react",
"stage-0"
],
"plugins": [
"transform-class-properties"
]
}
This is the list of my dependencies that are installed

I expected the error to tell me what loader I needed to install to use with Chart.js but it does not specify. If anyone knows which loader I need to install and where I should put it in my files that would be awesome. TIA!

Answer
Chart.js version 3 is not compatible. Change it to ^2.9.4. The same problem as you and I have been solved.
