Migrating an Angular Project to Use Liferay npm Bundler 2.x

Important

The Liferay npm bundler is deprecated of Liferay 2024.Q4/Portal GA129, and it’s planned for future removal.

Follow these steps to migrate your Angular project to use liferay-npm-bundler 2.x. While liferay-npm-bundler 1.x relied on Babel to perform some transformation steps, these transformations are now automatically applied in version 2.x. Therefore, you should remove Babel from your project:

Update the liferay-npm-bundler dependency in your package.json to version 2.x:

{
  "devDependencies": {
    ...
    "liferay-npm-bundler": "^2.0.0",
    ...
  },
  ...
}

Remove all liferay-npm-bundler-preset-* dependencies from your package.json because liferay-npm-bundler 2.x includes these by default.
Remove any bundler presets you configured in your .npmbundlerrc file. liferay-npm-bundler 2.x includes one smart preset that handles all frameworks automatically.
Open your tsconfig.json file and replace the "module": "amd" compiler option with the configuration shown below to produce CommonJS modules:
```
{
  "compilerOptions": {
    ...
    "module": "commonjs",
    ...
  }
}
```
Delete the .babelrc file to remove the Babel configuration.
Remove Babel from your package.json build process so it matches the configuration below:
```
{
  "scripts": {
    "build": "tsc && liferay-npm-bundler"
  },
  ...
}
```
Remove the following Babel dependencies from your package.json devDependencies:
```
"babel-cli": "6.26.0",
"babel-preset-liferay-amd": "1.2.2"
```
