What is the process for utilizing a personalized Typescript Declaration file (.d.ts) in an Angular project?

In my Web API project, I am using TypeLite to generate Typescript interfaces from C# POCOs. The resulting file looks like this:

// TypeLite.Net4.d.ts
declare namespace MyNamespace.Models {
    interface InvoiceModel {
        billingPeriodId: number;
        createdDate: Date;
        invoiceId: number;
        invoiceNumber: number;
        organizationId: number;
        paidDate: Date;
        total: number;
    }
}

Now, I want to utilize this file in my Angular project, but I'm struggling to find a clear explanation on how to do it. Despite trying various methods found online, such as adding it to my tsconfig.json in the files, include, or typeRoots sections, I still can't get it to work. Every attempt results in the error message

TS2304: Cannot find name 'InvoiceModel'
. How exactly should I go about incorporating it?

Answer №1

It seems like there is a missing reference to the declaration file in your TypeScript code. By not including this, you may encounter errors when trying to use the generated typescript declaration file.

You mentioned that you have tried various solutions found online, such as adding it to your tsconfig.json file in different sections like files, include, or typeRoots.

In order to properly reference the declaration file, you can utilize triple-slash-directives. This will help resolve any issues related to missing references.

To fix this issue, make sure to add the following code at the beginning of the file where you plan to use the declaration:

/// reference path=".../path/to/file" />
