Error: In Angular and Typescript, the function this.$resource is not recognized

I keep encountering a TypeError: this.$resource is not a function. Below is the code snippet causing the issue:

export class DataAccessService
    implements IDataAccessService {

    static $inject = ["$resource"];
    constructor(private $resource: ng.resource.IResourceService) {
    }

    getTravelExpenseType(): ng.resource.IResourceClass<T> {
        return this.$resource('URL:id', {}, {});
    }
}

common.service("dataAccessService",
    [DataAccessService]);

Answer №1

custom.service("dataAccessService",
    [DataAccessService]);

The issue lies in the way you are defining your service. By passing an array as the service definition, you need to include the dependencies to inject first, followed by the constructor as the last element. Without listing any dependencies, nothing will be injected.

To resolve this, simply remove the array:

custom.service("dataAccessService", DataAccessService);
