# Mutable Webpack Angular Builder
[](/LICENSE.txt)  
**mutable-webpack-angular-builder allows to freely modified the Webpack configuration generated before Angular ng use it for building.**
This project is licensed under the terms of the [MIT license](/LICENSE.txt).
## Quick Start
`package.json`:
```json
..
"devDependencies": {
"@angular-devkit/build-angular": "*",
"mutable-webpack-angular-builder": "1.0.0",
..
```
`angular.json`:
```json
..
"architect": {
"build": {
"builder": "mutable-webpack-angular-builder:browser",
"options": {
"mutatorFile": "webpack.config.mutator.js",
..
```
`webpack.config.mutator.js`:
```js
module.exports = (sourceWebpack) => {
const filteredRules = sourceWebpack.module.rules.filter(
(rule) => !rule.test instanceof RegExp || !rule.test.test('.css')
)
sourceWebpack.module.rules = filteredRules
return sourceWebpack
}
```
## Goal
Many things in Angular Ng processes are **hard-coded** and it is difficult to do some advanced customization[1]. The purpose of mutable-webpack-angular-builder is to allow for **fully modification of the Webpack Configuration provided by Angular** for more "advanced" uses.
> [1] Angular Ng processes are quite closed (and documentation is sometimes scattered and with a lot of "WIP").
> There are other builders like @angular-builders/custom-webpack, which allows only to do merging of Webpack options.
## Using/Configuration
### Prerequisites
* @angular-devkit/build-angular.
### Configuration
1 . Add **mutable-webpack-angular-builder** (and prerequisite) to `package.json`:
```json
..
"devDependencies": {
"@angular-devkit/build-angular": "*",
"mutable-webpack-angular-builder": "1.0.0",
..
```
2 . Set `builder` to mutable-webpack-angular-builder in `angular.json`:
```json
..
"architect": {
"build": {
"builder": "mutable-webpack-angular-builder:browser",
..
```
> Usually set as `"builder": "@angular-devkit/build-angular:browser"`.
3 . Add `"mutatorFile"` option to the builder to indicate the file that will contain the function that mutates the Webpack configuration:
```json
..
"build": {
"builder": "mutable-webpack-angular-builder:browser",
"options": {
"mutatorFile": "webpack.config.mutator.js",
..
```
> `mutatorFile` option is an additional option introduced by mutable-webpack-angular-builder.
> If the option is not defined, then mutable-webpack-angular-builder:browser will silently "fail", i.e. no mutation will be applied.
4 . Create the function that mutates the Webpack configuration:
```js
(sourceWebpack) => {
// do something with the Original Webpack Configuration
return sourceWebpack // return the Modified Webpack Configuration
}
```
E.g: The following removes some module rules that do not work quite well with React, and add some new rules (not shown)
```js
(sourceWebpack) => {
const filteredRules = sourceWebpack.module.rules.filter(
(rule) => !rule.test instanceof RegExp || !rule.test.test('.css')
)
filteredRules.push(reactRule)
filteredRules.push(cssRule)
sourceWebpack.module.rules = filteredRules
return sourceWebpack
}
```
> For an actual use example, see [basecode-ionic-react project](https://github.com/gmullerb/basecode-ionic-react)
5 . Export the mutator function using CommonJs (which is what is use by Angular Ng to load this):
`webpack.config.mutator.js`:
```js
module.exports = (sourceWebpack) => {
// do something with the Original Webpack Configuration
return sourceWebpack // return the Modified Webpack Configuration
}
```
### Advanced Configuration
A . Additional options may be define and use since no validation is imposed on the Builder's options:
`angular.json`:
```json
..
"architect": {
"build": {
"builder": "mutable-webpack-angular-builder:browser",
"options": {
"mutatorFile": "webpack.config.mutator.js",
"option1": "..",
"optionN": "..",
..
```
B . Mutator function additionally receive an object with the fields been used to call the Angular Ng Webpack's creator:
```js
(webpack: WebpackOptions, parameters: {root: string, projectRoot: string, host, options: {}}) => WebpackOptions
```
Then, the Mutator function can be:
```js
(sourceWebpack, parameters) => {
// do something with the Original Webpack Configuration
// use the project root path: parameters.projectRoot
// use an Additional options: parameters.option1
return sourceWebpack // return the Modified Webpack Configuration
}
```
