File resolution issue with TypeScript

While I am aware that using TypeScript outFile is generally advised against, I currently have no choice but to utilize it until a more suitable solution like AMD can be implemented.

It seems like there may be a "module splitting issue" in my project. In the same directory, I have two files:

Contents of referencedFile.ts:

module my.namespace {

   export class one {
   }

   export class two {
   }
}

Contents of anotherClass.ts:

module my.namespace {
  export class anotherClass {
      constructor() {
         // Error message: "JavaScript runtime error: Object doesn't support this action"
         var x = new my.namespace.one();
      }
   }
}

Upon runtime, the error "Object doesn't support this action" occurs when attempting to create a new instance of the "one" class. Upon further investigation within the constructor of anotherClass, it appears that my.namespace.one and my.namespace.two are not accessible at that point.

I tried adding the following line at the top of anotherClass.ts, but it did not resolve the issue:

/// <reference path="referencedFile.ts" />

In my Visual Studio TypeScript settings, I have "Combine Javascript output into one file" set to "Scripts\oneFile.js". Checking the generated "oneFile.js", I can confirm that the code from referencedFile.ts exists before the code from anotherClass.js, so it seems like there shouldn't be an ordering problem.

What could be causing this discrepancy?

Answer №1

Received Error Message:

// THROWS ERROR "JavaScript runtime error: Object doesn't support this action"

It appears that the sequence is incorrect.

Correct Sequence using outFile

To establish proper order, you can employ the traditional reference file technique. Detailed information can be found here : https://github.com/TypeStrong/grunt-ts#javascript-generation 🌹

PS: Although you are likely aware of my views on this matter as outlined in https://basarat.gitbooks.io/typescript/content/docs/tips/outFile.html, it is still beneficial to mention for others.

Answer №2

The problem arose because I had mistakenly installed typescript 1.7.6 alongside version 1.8.36 while using Visual Studio 2015.
