Making an API call within visual class.

Is it possible to make an API call using fetch in a custom visual.

I have set the privallages to allow web access to the API url and when I run the following function it succesfully prints the data in the console.

private async getData() { try { const url: string = 'http://localhost:3000/api/routes' const response = await fetch(url) const data = await response.json(); console.log(data); //return data; } catch (error) { console.log(error); } }

The thing im struggling with is saving the returned data to a variable to use to create my visual.

When I try to return the data to a variable in the constructor or update methods the variable is undefined or promise pending.
