I am working on a project with API. API response is 404 not found. I need to handle this status code without a new page. I want to add an window.confirm("not found"). However, I couldnt do that, because when API says 404 there is no response so I couldn't check the response. How can I do that without using new page? How can I handle that? Here is my response code:
const response = await instance.get(`?q=${q}&appid=${appid}`);
if (!response) {
console.log("ceren");
}
It never prints "ceren". I tried response ==="", response ===null, response.data===null, and so on
The response object is never null. It's an object that, along with many other keys, includes the status. Moreover, if the request fails, it will throw an error (due to the await, though outside of this function it will be a Promise rejection), so you can just catch that:
return instance.get(`?q=${q}&appid=${appid}`).then(/*...*/).catch((error) => console.log('Request failed!'));
Or, if you must use an await:
try {
const response = await instance.get(`?q=${q}&appid=${appid}`);
} catch (error) {
console.log('Request failed!');
}
