Typescript internal module not recognized by VS Code

Question

I am trying to separate my typescript classes in separate files using internal modules. However, the main.ts file will not load or recognize the sub modules.

Answer 1

To compile several .ts files into one big .js file using a VS Code task, you need to remove the 'args' from tasks.json and add the "out" argument to tsconfig.json

tasks.json

{
    "version": "0.1.0",
    "command": "tsc",
    "isShellCommand": true,
    "showOutput": "silent",
    "problemMatcher": "$tsc"
}

tsconfig.json

{
    "compilerOptions": {
        "sourceMap":  true,
        "out": "myapp.js"
    }
}

Note: When input files are specified on the command line, tsconfig.json files are ignored.

Answer 2

main.ts

/// <reference path="car.ts" />
var c = new Car("red");

car.ts

class Car {
    color: string;
    constructor(color: string) {
        this.color = color;
        console.log("created a new " + color + " car");
    }
}

tsconfig.json

{
    "compilerOptions": {
        "sourceMap":  true, 
        "outFile": "main.js"
    },
    "files": [
        "main.ts",
        "car.ts"
    ]
}

tasks.json

Kokodoko: I finally found the problem! You have to OMIT the "args" option inside "tasks.json", only then will the arguments in tsconfig.json be used! I found the answer here: github.com/Microsoft/typescript/wiki/tsconfig.json. It says: When input files are specified on the command line, tsconfig.json files are ignored
