How can I get the response JSON in chrome extension

Question

I want to make a chrome extension. I need to get the response JSON what can be seen in chrome's developer tools. It's a post by using fetch. Which API or javascript way can I use?

Answer 1

Just use Fetch API (another good alternative is axios )

example:

async function getData() {
    try {
        const response = await fetch('https://your-res-website.com');
        const resJson = await response.json();

        return resJson;
    } catch (error) {
        console.warn('getData error', error);
    }

    return null;
}

getData().then(data => console.log(data));
