`registerWebhooks()` is taking too long to run

[nullndr]

I noticed the LCP in my app has been raised recently, so after some debugging I found that the call to registerWebhooks() in the afterAuth() hook is taking an exagerate amount of seconds (~10s).

Manually registering all my webhooks topic (I currently have 12 topics) inside a Promise.all() decreased the time to 300ms.

Question: Are you doing this manual registration still in the afterAuth hook? or elsewhere?

Hi @lizkenyon.

My custom registration is still in the afterAuth() hook:

export const shopifyConfig = shopifyApp({
  ...
  webhooks: undefined,
  hooks: {
    async afterAuth({ session, admin }) {
      console.time("customRegister");
      await Promise.all(topics.map(topic => registerWebhook(topic, session)));
      console.timeEnd("customRegister"); // ~300ms
    }
  },
});

async function registerWebhook(
  topic: WebhookSubscriptionTopic,
  { shop: shopifyDomain, accessToken}: Session
) {
  if(accessToken == null) {
    return;
  }

  const genql = await createGenqlClient({ shopifyDomain, acessToken });

  return genql.mutation({
    eventBridgeWebhookSubscriptionCreate: {
      ...
    },
  });
}

With the registerWebhooks() call:

export const shopifyConfig = shopifyApp({
  ...
  webhooks: {
    ...
  },
  hooks: {
    async afterAuth({ session, admin }) {
      console.time("registerWebhook()");
      await shopifyConfig.registerWebhooks({ session });
      console.timeEnd("registerWebhook()"); // ~9/10s
    }
  },
});

Initially I thought the biggest problem is in the call to runMutation() in the shopify-app-js package that is awaited on each call, but on a second thought it doesn't look enough to slow down with seconds.

Also, there seems to be a problem even with the afterAuth() (But probably this should be in a separated issue).

I have my app under the /app route, that imports a React.Context of my shop with a simple Prisma model:

export const findShop = async ({ shopifyDomain }: ShopifyDomain) => {
  const shop = await db.$queryRaw<[Shop]>`
    select * from "Shop" where "shopifyDomain" = ${shopifyDomain};`;
  return shop[0];
};

When I have the call to registerWebhooks() at the start of afterAuth(), this model returns undefined, after a refresh I can see the shop entity correctly. This looks like a problem with the afterAuth(), since the remix loader loads before the registration process I do in the body of afterAuth(), indeed if I run:

async afterAuth({ admin, session }) {
  await Promise.all([
    shopifyConfig.registerWebhooks({ session }),
    installOrUpdateShop(admin, session),
  ]);
}

The model correctly returns the shop entity.

I forgot to mention that my @shopify/shopify-app-remix is 2.8.2, sadly I can't update to 3.0.

Hi yes, could you create a separate issue for the AfterAuth. Just want to make sure we don't lose track of it. Thanks! :)

And then I will triage the registerWebhooks issue and we will look into it.

Excellent, thank you so much!

Hi @lizkenyon , any updates on this?

[lizkenyon]

Hi there 👋

Sorry for the delay in this.

If you haven't already I would recommend checking out App-specific webhook subscriptions. You define the webhook subscriptions in the shopify.app.toml, and Shopify manages creating the subscription instead of registering them in the afterAuth hook.

Hi! I am aware of the that and I already moved some webhooks like shop/update to the .toml file. However the main issue remains.
