Angular 2 - Ahead-of-Time Compilation (AoT)

I've been diving into Angular 2 and came across this tutorial to learn more.

After using the command below to compile my app:

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

I encountered an issue where only node_modules were generated, no output from my actual app. https://i.sstatic.net/fth61.png

If anyone has encountered a similar problem or knows of an alternative solution, your help would be greatly appreciated.

Here is my tsconfig-aot.json configuration:

{
  "compilerOptions": {
    "target": "es5",
    "module": "es2015",
    ...
  },

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

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

//https://github.com/angular/angular/issues/11689

And here is my package.json file:

... ...

Upon further research, some suggest that downgrading TypeScript to version 2.0.10 may solve the issue, but unfortunately, it didn't work for me.

For context, I am running Windows 7.

Answer №1

It seems there may not be another solution to this issue as the angular compiler relies heavily on the typescript compiler. While I haven't had the chance to test it in angular v2.4.0, it's possible that the problem could be resolved in that particular version of the angular compiler.

If you're still facing difficulties with angular v2.2.3, downgrading typescript to 2.0.10 is a viable workaround. Ensure that the typescript dependency version is clearly specified in your packages.json file like so:

"devDependencies": {
  ...
  "typescript": "~2.0.10",
  ...
}

Alternatively, you can specify the exact version like this:

"devDependencies": {
  ...
  "typescript": "2.0.10",
  ...
}

In the example provided, a caret range was used which resulted in npm fetching the latest version within the major version 2 (i.e., 2.1.x). https://docs.npmjs.com/misc/semver#caret-ranges-123-025-004
