我的Angualr项目加载速度非常慢 . 所以我编译Angular AOT，但输出错误信息 .

tsconfig-aot.json：

{
    "compilerOptions": {
        "target": "es5",
        "module": "es2015",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "lib": ["es2015", "dom"],
        "noImplicitAny": true,
        "suppressImplicitAnyIndexErrors": true,
        "typeRoots": [
            "./node_modules/@types/"
        ],
        "noImplicitAny": false,
        "suppressImplicitAnyIndexErrors": false
    },

    "files": [
        "src/app/app.module.ts",
        "src/main.ts"
    ],

    "angularCompilerOptions": {
        "genDir": "aot",
        "skipMetadataEmit" : true
    }
}

main.ts：

import { platformBrowser }    from '@angular/platform-browser';
import { AppModuleNgFactory } from '../aot/src/app/app.module.ngfactory';

platformBrowser().bootstrapModuleFactory( AppModuleNgFactory );

  • node_modules / .bin / ngc -p tsconfig-aot.json .

  • ng服务 .

输出错误信息后1-> 2 .
