Conceal a specific segment on the web page if the API call in Angular does not return any data

I'm currently working with data retrieved through an API call and I need assistance in implementing code to hide a section when there is no data being fetched. Could you provide a sample code for this?

Answer №1

One helpful solution could involve exploring the ngIf directive. By using this directive, the content will only be displayed if the specified condition is satisfied. In this case, you can set the condition to evaluate as false when the API call results in an empty response, and true when there is data available.

Answer №2

this.getData<any>("endpoint").observe((response:any) => {
    if (!response) {
        console.log("No response found");
    }
})
