Hi.
I solved it following this simple steps:
1. Create “config” directory in the root path of my project with following “webpack.config.js” file:
var webpack = require('webpack');
const defaultWebpackConfig = require('../node_modules/@ionic/app-scripts/config/webpack.config.js');
module.exports = function () {
defaultWebpackConfig.prod.output['chunkFilename'] = "[name].[chunkhash].chunk.js";
defaultWebpackConfig.dev.output['chunkFilename'] = "[name].[chunkhash].chunk.js";
return defaultWebpackConfig;
};
2. Add this lines to my package.json:
"config": {
"ionic_webpack": "./config/webpack.config.js"
},
Et voilà! Problem solved.
Hope it helps!
