How to construct a simple "delay" plugin.

[mikecann]

I want to delay every query by a given number of time so when developing locally I have a realistic testing scenario.

I thought this would do it but it doesnt see to work.

import type { Plugin } from "@envelop/core";
import { wait } from "@battletabs/essentials";

export const useDelayPlugin = (timeMs: number): Plugin => ({
  onExecute({ executeFn, setExecuteFn }) {
    setExecuteFn(async (args) => {
      await wait(timeMs);
      return executeFn(args);
    });
  },
});

Any ideas?

Nevermind, the above does work, I was just making a mistake elsewhere in the code :P

Btw, it might conflict with some other plugins, if you are replacing the execute function. You might want to add a plugin that delays the context building, and that will add time to the total execution (unless what you really want is to delay the execute function on purpose)

@dotansimha I dont think adding a delay to context building would work for subscriptions because the context is only built once?

So I think this is the only way to do it that works for both HTTP and subscriptions

Yeah, you are right 💯
