I have a fetch function that takes a URL and gives out the response.

public getHTTPResponse(URL : string) {
    fetch(URL).then(function(response) {
        return response;
    })
}

I try to use the response in a IF-statement.

For example if the response is 200 it should be true. So far I have:

if (this.getHTTPResponse(item.ListUrl) === )

Where item.ListUrl is a link. I can't get my head around on what I should have on the right side of the operator to test if the response is 200 (or any other for that matter). Any help?

• javascript
• typescript
• http
• fetch

• You can't do anything on the right hand side; getHTTPResponse doesn't currently return anything, and if it did paring promise equality rarely makes sense. – jonrsharpe Commented Nov 18, 2018 at 9:26

• Can you post your success and failure response here so we can see what type of response it's returning – Prashant Pimpale Commented Nov 18, 2018 at 9:58

The response object has a property status which value is an integer. Try like that:

  fetch(URL)
   .then(function(response) {
      if(response.status === 200) {
         // do something
       };
     })
