Important to remember!

To get and post real data you need to have a running instance of the bl-api

How to use this library

To import this library in your module:

imports: [..., BlConnectModule]

Now you can use the services in your components. The services are explained below.

Error handling

When you use a service and that service rejects with an error you get a object of the type BlApiError. The error classes are provided by bl-model and are therefore easy to understand. We have four different types of BlApiErrors that bl-connect services throws, under is a description for all of them:

BlApiLoginRequiredError

Used when the request requires a login and no valid access token is found. The user needs to login to get this document.

BlApiPermissionDeniedError

Used when the request is valid, but the user lacks the given permission for this endpoint.

BlApiNotFoundError

Used when the document asked for is not found.

BlApiError

This is error is thrown if none of the above errors is applicable.

Example of error handling:

myMethod() {

	this.itemService.get().then((items: Item[]) => {

		//do something

	}).catch((apiErr: BlApiError) => {

		if (apiErr instanceof BlApiLoginRequiredError) {
			// do something with login error
		}

		if (apiErr instanceof BlApiPermissionDeniedError) {
			//do something with permission denied error
		}

		if (apiErr instanceof BlApiNotFoundError) {
			//do something with document not found error
		}

		if (apiErr instanceof BlApiError) {
			// do something with the general error
		}
	}
}
