Switching from angular.json to webpack-obfuscator

Hello,

I'm very sorry to ask such a basic question but I need guidance. I've got currently in my angular.json for the build:

```
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.app.json",
"assets": [
"src/favicon.ico",
"src/assets",
{
"glob": "**/*",
"input": "node_modules/ngx-monaco-editor/assets/monaco",
"output": "/assets/monaco"
}

],
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css",
"node_modules/angular-notifier/styles.css",
"node_modules/primeicons/primeicons.css",
"node_modules/primeng/resources/themes/nova-dark/theme.css",
"node_modules/primeng/resources/primeng.min.css"

],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
},
"configurations": {
"production": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
],
"optimization": true,
"outputHashing": "all",
"sourceMap": false,
"extractCss": true,
"namedChunks": false,
"aot": true,
"extractLicenses": true,
"vendorChunk": false,
"buildOptimizer": true
}
}
},
```
This is fairly standard; we've not changed much. So firstly I install the custom webpack dependency:

npm i @angular-builders/custom-webpack -D

Then I have to configure the custom-webpack to include the obfuscation so I modify the above to the following:

```
"build": {
"builder": "@angular-builders/custom-webpack:browser",
"options": {
"customWebpackConfig": {
"path": "./custom-webpack.config.js",
"replaceDuplicatePlugins": true
},
"outputPath": "dist",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.app.json",
"assets": [
"src/favicon.ico",
"src/assets",
{
"glob": "**/*",
"input": "node_modules/ngx-monaco-editor/assets/monaco",
"output": "/assets/monaco"
}

],
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css",
"node_modules/angular-notifier/styles.css",
"node_modules/primeicons/primeicons.css",
"node_modules/primeng/resources/themes/nova-dark/theme.css",
"node_modules/primeng/resources/primeng.min.css"

],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
]
},
"configurations": {
"production": {
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}
],
"optimization": true,
"outputHashing": "all",
"sourceMap": false,
"extractCss": true,
"namedChunks": false,
"aot": true,
"extractLicenses": true,
"vendorChunk": false,
"buildOptimizer": true
}
}
},
```

I then reference the obfuscation file custom-webpack.config.js which is as follows:

```
// webpack.config.js
'use strict';

const JavaScriptObfuscator = require('webpack-obfuscator');

module.exports = {
entry: {
'main': "dist/main.js",
},
output: {
path: 'dist',
filename: '[name].obs.js' // output: abc.js, cde.js
},
plugins: [
new JavaScriptObfuscator({
rotateUnicodeArray: true
}, [])
]
};
```
I'm on Angular 8.3.25 but this is giving me 'An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.'.

Again; I'm sorry if this is not specific to this tool but I'm unsure how to get from the angular.json I have now to the obfuscation detailed in the guide?

I'm happy to write this up in a detailed tutorial when done!

Commencez par la configuration de build d’Angular 8 dans angular.json et par l’exemple custom-webpack.config.js, puis reproduisez l’erreur '..getProjectMetadata' avec la configuration signalée. Vérifiez comment @angular-builders/custom-webpack s’intègre au browser builder et comment webpack-obfuscator attend sa configuration d’entry et d’output. C’est terminé lorsque le build de production Angular s’achève correctement et que la configuration d’obfuscation est appliquée sans cette exception.
