Is Angular 2 giving you trouble with the AoT compilation and module.id error?

I need to set up AoT compilation for my Angular 2 project.

My application is organized into a js directory where all generated .js files are stored, and an app directory containing my .ts, .html, and .css files.

For the AoT compilation process, I am using the tsconfig.aot.json file:

{
  "compilerOptions": {
    // compiler options here
  },
  "files": [
    "app/main.ts"
  ],
  "exclude": [
    "node_modules",
    "js",
    "app"
  ],
  "compileOnSave": false
}

And the script looks like this:

"ngc": "ngc -p tsconfig.aot.json && npm run copy \"app/*\" \"compiled\" "

Here's how my components are structured:

 @Component({
    selector: 'fs-mainbar',
    templateUrl: 'app/mainbar/mainbar.component.html'
 })
export class MainbarComponent {

However, when running the script, I encounter the following error:

Error: Compilation failed. Resource file not found...
// Error details go on

It seems like I should be using module.id, but due to the separation of my app directories, I have to adjust it in this way:

 @Component({
     moduleId: module.id.replace("/js/", "/app/"),
     selector: 'escl-mainbar',
     templateUrl: './mainbar.component.html'
 })
export class MainbarComponent {

But this modification leads to another error:

Error encountered resolving symbol values statically. Calling function 'module', function calls are not supported...
// Further error details provided

At this point, I'm stuck. Any assistance or suggestions on how to resolve this issue would be greatly appreciated :)

Answer №1

Give this a try:

 export function updateModuleId() {
     return moduleId.replace("/js/", "/app/");
 }

 @Component({
     moduleId: updateModuleId(),
     selector: 'escl-mainbar',
     templateUrl: './mainbar.component.html'
 })
export class MainbarComponent { }
