webpack.config.js

`const { shareAll, withModuleFederationPlugin } = require('@angular-architects/module-federation/webpack');
const env = require('./public/assets/architectural_config/environment.json');

module.exports = withModuleFederationPlugin({

remotes: {
"EquipmentApp": ${env.remoteUrl}/remoteEntry.js,
},

shared: {
...shareAll({ singleton: true, strictVersion: true, requiredVersion: 'auto' }),
'at-yard-lib': {
singleton: true,
strictVersion: false, // Changed to false
requiredVersion: 'auto', // Added this
eager: false // Added this to ensure proper loading
},
'atai-angular-library-v2': {
singleton: true,
strictVersion: false, // Changed to false
requiredVersion: 'auto', // Added this
eager: true // Added this
},
},

});`
