Can you simulate a delay?

[nonopolarity]

Can you possibly add a delay so we can do some debugging, such as

fetch(`https://jsonplaceholder.typicode.com/users/${userID}?delay=5`)

so the above can do a 5 seconds delay? Maybe the range can be 0 to 5 so that it doesn't stress your server out. (such as 30 seconds delay which can be a lot of requests bottled up). Alternatively if you want to support millisecond, then maybe

fetch(`https://jsonplaceholder.typicode.com/users/${userID}?delay=3000`)

This is for example, if we want to debug / test a slow response, and the user already click on a new link or image that fetches that data faster than the earlier response, so that the earlier response should really be ignored or canceled by our app.

Is this documented anywhere? I can't find any documentation around this even though it works

use _dealy

100

so I think you mean use _delay

so it will be

fetch(`https://jsonplaceholder.typicode.com/users/${userID}?_delay=5`)

P.S. The line

fetch(`https://jsonplaceholder.typicode.com/users/${userID}?_delay=5000`)

sometimes has the delay, but sometimes not. (so I am not even sure if it was just a random network delay)

It needs to be 5000 to mean 5 seconds

Might be they optimize ip-base cahce to prevent some DDoS attack.

You can add randome parameter and it should works. (I've just tested with curl)

fetch(`https://jsonplaceholder.typicode.com/users/${userID}?_delay=5000&dummy=${randomNumber()}`)

And yes, it is very strange nothing documented about this.

Hi,

JSONPlaceholder doesn't support _delay. So addind it does nothing actually.

You can however use the CLI locally with v0.17 json-server --delay 5000 db.json https://github.com/typicode/json-server/tree/v0.17.4

Or use Chrome's Network tab > throtling to delay requests.

You can use DummyJSON for this: https://dummyjson.com/docs#intro-delay

fetch('https://dummyjson.com/users/1/?delay=1000');
