Retry based on body content

[Zeranoe]

I'd like to retry a request N times with M seconds between each request, based on the response json data. The page returns a 200 status, so the retry isn't being triggered by default. Here is what I have so far:

async function waitTillComplete(name) {
    return await got(`https://api.gfycat.com/v1/gfycats/fetch/status/${name}`, {
        retry: {retries: 5, statusCodes: [200]},
        hooks: {
            afterResponse: [
                (response, retry) => {
                    const body = JSON.parse(response.body);

                    if (body.task != 'complete') {
                        return retry;
                    }

                    return response;
                }
            ]
        }
    });
}

I'm not sure how to force a retry with a 200 status, and any help would be appreciated.

Why not just wrap in a while statement?

async function waitTillComplete(name) {
    let retries = 0;
    while (retries < 5) {
        retries += 1;
        // note - this won't retry on request failures or error codes, change opts accordingly
        const response = await got(`https://api.gfycat.com/v1/gfycats/fetch/status/${name}`);
        // could use "json" option of got insted to auto-json parse
        const {task} = JSON.parse(response.body);
        if (task == 'complete') {
            return response;
        }
    }
    throw new Error(`Max retries reached for ${name}`);
}

I was just trying to use the built in retry functionality, but I've been using a loop for now.

In your example, you're not calling the retry function. Should be:

if (body.task != 'complete') {
    return retry();
}
