Encountering an AOT error while running ng build using Angular CLI

After successfully creating an application using Angular CLI with JIT compilation, I decided to optimize its performance by converting it to AOT compilation.

Following the instructions provided on angular.io, I made the necessary changes to convert all files into ngFactory and completed the rollup process without any errors.

However, when running ng build --aot, I encountered the following error:

Tried to find bootstrap code, but could not. Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options. Error: Tried to find bootstrap code, but could not. Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options. // Error message details

Here is my main.ts file:

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

console.log('Running AOT compiled');
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);

And this is my tsconfig-aot.json configuration:

{
  "compilerOptions": {
    // Compiler Options details
  },

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

  "angularCompilerOptions": {
    // Angular Compiler Options details
  }
}

Has anyone else faced a similar issue?

Answer №1

As noted in the feedback, when utilizing the command line interface, executing ng build --prod will handle the building process including aot and tree shaking. If you prefer to take a more hands-on approach, as demonstrated in your example, make sure to include an additional line in your angularCompileOptions like so:

  "angularCompilerOptions": {
    "genDir": "aot",
    "entryModule": "app/app.module#AppModule",
    "skipMetadataEmit" : true
  }

Since you haven't shared your specific module, it may be necessary to adjust the path and module name accordingly, but that attribute is likely the missing piece of the puzzle.
