Expecting commitment on the horizon with the utilization of async/await in a TypeScript

Every time I use the loadhtml method within show function, I receive a pending promise. Is there a way to obtain the value without needing a callback function? The code snippet is provided below for reference.

   async loadhtml(url: string) {
            var data =$.get(url).then(response=>{
                console.log("response=>",response)
                return response
            });
            return await data
        }

 show() {
      var data = this.loadhtml(require("../../template/template1.tpl"));
       console.log("html content=> ",data);
} 

Answer №1

To ensure asynchronous loading of HTML content, you can encapsulate it in a promise and return it. This will allow you to utilize the await keyword in the calling function in order to pause execution until the HTML content is fetched.

async loadHTML(url: string) {
  return new Promise((resolve, reject) => {
    $.get(url).then( response => {
      console.log("response=>", response)
      resolve(response)
    });
  });
}

async displayContent() {
  var htmlData = await this.loadHTML(require("../../template/template1.tpl"));
  console.log("HTML content=> ", htmlData);
}
