It has always been experimental (never hit\n`1.0.0`) and was an internal package for the Angular CLI. All the relevant functionality has been\nmoved into\n[`@angular-devkit/build-angular`](https://npmjs.com/package/@angular-devkit/build-angular).\n\n## Available optimizations\n\nTransformations applied depend on file content:\n\n- [Class fold](#class-fold), [Scrub file](#scrub-file) and [Prefix functions](#prefix-functions): applied to Angular apps and libraries.\n- [Import tslib](#import-tslib): applied when TypeScript helpers are found.\n\nSome of these optimizations add `/*@__PURE__*/` comments.\nThese are used by JS optimization tools to identify pure functions that can potentially be dropped.\n\n### Class fold\n\nStatic properties are folded into ES5 classes:\n\n```typescript\n// input\nvar Clazz = (function () {\n  function Clazz() {}\n  return Clazz;\n})();\nClazz.prop = 1;\n\n// output\nvar Clazz = (function () {\n  function Clazz() {}\n  Clazz.prop = 1;\n  return Clazz;\n})();\n```\n\n### Scrub file\n\nAngular decorators, property decorators and constructor parameters are removed, while leaving non-Angular ones intact.\n\n```typescript\n// input\nimport { Injectable, Input, Component } from '@angular/core';\nimport { NotInjectable, NotComponent, NotInput } from 'another-lib';\nvar Clazz = (function () {\n  function Clazz() {}\n  return Clazz;\n})();\nClazz.decorators = [{ type: Injectable }, { type: NotInjectable }];\nClazz.propDecorators = { 'ngIf': [{ type: Input }] };\nClazz.ctorParameters = function () {\n  return [{ type: Injector }];\n};\nvar ComponentClazz = (function () {\n  function ComponentClazz() {}\n  __decorate([Input(), __metadata('design:type', Object)], Clazz.prototype, 'selected', void 0);\n  __decorate(\n    [NotInput(), __metadata('design:type', Object)],\n    Clazz.prototype,\n    'notSelected',\n    void 0,\n  );\n  ComponentClazz = __decorate(\n    [\n      NotComponent(),\n      Component({\n        selector: 'app-root',\n        templateUrl: './app.component.html',\n        styleUrls: ['./app.component.css'],\n      }),\n    ],\n    ComponentClazz,\n  );\n  return ComponentClazz;\n})();\n\n// output\nimport { Injectable, Input, Component } from '@angular/core';\nimport { NotInjectable, NotComponent } from 'another-lib';\nvar Clazz = (function () {\n  function Clazz() {}\n  return Clazz;\n})();\nClazz.decorators = [{ type: NotInjectable }];\nvar ComponentClazz = (function () {\n  function ComponentClazz() {}\n  __decorate(\n    [NotInput(), __metadata('design:type', Object)],\n    Clazz.prototype,\n    'notSelected',\n    void 0,\n  );\n  ComponentClazz = __decorate([NotComponent()], ComponentClazz);\n  return ComponentClazz;\n})();\n```\n\n### Prefix functions\n\nAdds `/*@__PURE__*/` comments to top level downleveled class declarations and instantiation.\n\nWarning: this transform assumes the file is a pure module. It should not be used with unpure modules.\n\n```typescript\n// input\nvar Clazz = (function () {\n  function Clazz() {}\n  return Clazz;\n})();\nvar newClazz = new Clazz();\nvar newClazzTwo = Clazz();\n\n// output\nvar Clazz = /*@__PURE__*/ (function () {\n  function Clazz() {}\n  return Clazz;\n})();\nvar newClazz = /*@__PURE__*/ new Clazz();\nvar newClazzTwo = /*@__PURE__*/ Clazz();\n```\n\n### Prefix Classes\n\nAdds `/*@__PURE__*/` to downleveled TypeScript classes.\n\n```typescript\n// input\nvar ReplayEvent = (function () {\n  function ReplayEvent(time, value) {\n    this.time = time;\n    this.value = value;\n  }\n  return ReplayEvent;\n})();\n\n// output\nvar ReplayEvent = /*@__PURE__*/ (function () {\n  function ReplayEvent(time, value) {\n    this.time = time;\n    this.value = value;\n  }\n  return ReplayEvent;\n})();\n```\n\n### Import tslib\n\nTypeScript helpers (`__extends/__decorate/__metadata/__param`) are replaced with `tslib` imports whenever found.\n\n```typescript\n// input\nvar __extends =\n  (this && this.__extends) ||\n  function (d, b) {\n    for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];\n    function __() {\n      this.constructor = d;\n    }\n    d.prototype = b === null ? Object.create(b) : ((__.prototype = b.prototype), new __());\n  };\n\n// output\nimport { __extends } from 'tslib';\n```\n\n### Wrap enums\n\nWrap downleveled TypeScript enums in a function, and adds `/*@__PURE__*/` comment.\n\n```typescript\n// input\nvar ChangeDetectionStrategy;\n(function (ChangeDetectionStrategy) {\n  ChangeDetectionStrategy[(ChangeDetectionStrategy['OnPush'] = 0)] = 'OnPush';\n  ChangeDetectionStrategy[(ChangeDetectionStrategy['Default'] = 1)] = 'Default';\n})(ChangeDetectionStrategy || (ChangeDetectionStrategy = {}));\n\n// output\nvar ChangeDetectionStrategy = /*@__PURE__*/ (function () {\n  var ChangeDetectionStrategy = {};\n  ChangeDetectionStrategy[(ChangeDetectionStrategy['OnPush'] = 0)] = 'OnPush';\n  ChangeDetectionStrategy[(ChangeDetectionStrategy['Default'] = 1)] = 'Default';\n  return ChangeDetectionStrategy;\n})();\n```\n\n## Library Usage\n\n```typescript\nimport { buildOptimizer } from '@angular-devkit/build-optimizer';\n\nconst transpiledContent = buildOptimizer({ content: input }).content;\n```\n\nAvailable options:\n\n```typescript\nexport interface BuildOptimizerOptions {\n  content?: string;\n  inputFilePath?: string;\n  outputFilePath?: string;\n  emitSourceMap?: boolean;\n  strict?: boolean;\n  isSideEffectFree?: boolean;\n}\n```\n\n## Webpack loader usage:\n\n```typescript\nimport { BuildOptimizerWebpackPlugin } from '@angular-devkit/build-optimizer';\n\nmodule.exports = {\n  plugins: [\n    new BuildOptimizerWebpackPlugin(),\n  ]\n  module: {\n    rules: [\n      {\n        test: /\\.js$/,\n        loader: '@angular-devkit/build-optimizer/webpack-loader',\n        options: {\n          sourceMap: false\n        }\n      }\n    ]\n  }\n}\n```\n\n## CLI usage\n\n```bash\nbuild-optimizer input.js\nbuild-optimizer input.js output.js\n```\n","engines":{"npm":"^6.11.0 || ^7.5.6 || >=8.0.0","node":"^12.20.0 || ^14.15.0 || >=16.10.0","yarn":">= 1.13.0"},"license":"MIT","typings":"src/index.d.ts","_npmUser":{"name":"google-wombot","email":"node-team-npm+wombot@google.com"},"homepage":"https://github.com/angular/angular-cli","keywords":["angular","Angular CLI","devkit","sdk","Angular DevKit"],"deprecated":"This package has been folded in @angular-devkit/build-angular and should no longer be needed.
