Maintaining accurate type-hinting with Typescript's external modules

Question

Maintaining accurate type-hinting with Typescript's external modules

Before I ask my question, I want to mention that I am utilizing Intellij IDEA.

In reference to this inquiry: How do you prevent naming conflicts when external typescript modules do not have a module name?

Imagine I have two Rectangle classes in different Rectangle.ts files but under different packages, for instance, src/utils/geom and src/utils/ui.

src/utils/geom/Rectangle.ts includes only the method calculateSurface(), whereas src/utils/ui/Rectangle.ts consists of only the method display().

If I were to call both of these classes in a single file, I would see both methods available in the type-hinting suggestions.

import GeomRectangle = require();
import UiRectangle = require();

var geom: GeomRectangle = new GeomRectangle();
var ui: UiRectangle = new UiRectangle();

// Both methods are now accessible
ui.calculateSurface();
ui.display();

I suspect it is because both Rectangle.ts files contain exports = Rectangle, which is likely used by Intellij IDEA to determine what suggestions to provide. Is my assumption correct? And is there a way to enable type-hinting without conflicting when using external modules with similarly named classes?

Answer №1

After testing out your code on Visual Studio, I encountered the following:

file/Rectangle.ts

class Rectangle {
    findArea() {
       console.log("a");
    }
}

export = Rectangle;

window/Rectangle.ts

class Rectangle {
    show() {
        console.log("b");
    }
}

export = Rectangle;

Validation.ts

import FileRectangle = require("./file/Rectangle");
import WindowRectangle = require("./window/Rectangle");


var fileRect: FileRectangle = new FileRectangle();
var windowRect: WindowRectangle = new WindowRectangle();

// Both methods are valid now
windowRect.findArea(); // encountering a compilation error here
windowRect.show();

The findArea method is not showing up in the intellisense options for the windowRect object.
An error occurs during compilation at the windowRect.findArea() line.

This issue may be related to a bug within Eclipse IDE or a configuration setting problem.
