Zustand /w persist + immer, not persisting multi-tenant.

saved should be persisting through different tenants, but it gets cleared every time. It should retrieve the persisted state and update it no? https://pastecord.com/oragaziboh.typescript

Do I need a server to use tRPC?

Since we use RQ at work for our product - I thought might as well bring tRPC into it since it couples things very well. We dont do anything serverless on the frontend, so curious if I need to install an adapter to Vite and spin up a server?

limiting json_agg

Having a bit of a skill issue limiting the amount of data returned from json_agg

      const query = ctx.db
        .select({
          ...groupByFilters,
          rowCount: sql<number>`count(${schema.returns.id})`.as(
            "row_count",
          ),
          data: sql`json_agg(${schema.returns})`,
        })
        .from(schema.returns)
        .groupBy(...Object.values(groupByFilters))
        .limit(limit + 1); // limit the amount of groups returned

      const query = ctx.db
        .select({
          ...groupByFilters,
          rowCount: sql<number>`count(${schema.returns.id})`.as(
            "row_count",
          ),
          data: sql`json_agg(${schema.returns})`,

        .from(schema.returns)
        .groupBy(...Object.values(groupByFilters))
        .limit(limit + 1); // limit the amount of groups returned

I tried to add a subquery, but I can't seem to get it right

Queues + DO's + DB connections

I distribute load to multiple different unique DO's, where each one creates a new connection. I keep getting PostgresError: Max client connections reached. I was under the impression that after DB operations are done, it will automatically close the connection by itself. My thinking is to spawn a unique durable object for insertions, and to keep it alive throughout my distribution process so i can minimize the amount of connections it opens. Any advice?

Having such a bad experience with Queues & DOs

I have a lot of data to fetch from an external API. I queue up each page which then distributes additional processing via durable objects. It starts out perfectly fine, but once it reaches half of the pages it needs to process, it just hangs. Each page has a unique shared ID to keep durable objects alive for in-memory state. After a page finishes fetching, I dispose the DO. Is there something I am not understanding? (this is all local & using RPC )

An RPC result was not disposed properly

I have a DO that returns an object and is marked as Disposable. I keep getting this error, and i'm not entirely sure how to go about it, because I thought it automatically disposes?

An RPC result was not disposed properly. One of the RPC calls you made expects you to call dispose() on the return value, but you didn't do so. You cannot rely on the garbage collector for this because it may take arbitrarily long before actually collecting unreachable objects.

Best way to retrieve Queue List within a CF worker?

I know there is a Queue API that you can fetch from a CF worker, but is there another way to do so?

attach a payload to queue batch rather than each message?

With CF queues, are you able to send a payload that’s attached to the actual batch, rather than each message? I would like to send a userId for example to the controller, rather than to each consumer message.

best approach to apply pollyfills?

A library I want to use within a CF worker imports “crypto”, so I need to apply a pollyfill that will use node:crypto instead. I’ve never messed around with pollyfills so I am not sure how to go about this correctly.

TRPC deserialization cuts off long string to client

I got an oauth2 URL that’s very long because scopes are added as search params. The URL returned to the client is cut off completely. Not sure how to go about this. Is this related to superjson somehow?

Mutation returning a long URL is being cut off

I have an authentication URL for an oauth2 provider that returns a long URL due to scopes being added. The server returns a cut-off version of it to the client. Not sure why.

How does tiered caching work in the CF worker other than enabling it?

This is what I understand in terms of control Workers have in-memory cache of x mb's, so you can define a memory cache via new Map for example. Workers can use Cache API via caches.default.put Both of these exist locally via colocation, so in-memory cache is going to be fastest, and then colo cache is second fastest in terms of latency for data retrieval.
If your data does not exist in both of those, tiered caching comes into play, and from my understanding its tied to the fetch api. What does this mean exactly? Would love a code example of the breakdown for:

1. check in-memory cache (db response)
2. check local cache (db respoonse)
3. check tiered cache (db response)
4. if non of those have the data needed, it would fetch data from a database (origin)

1. check in-memory cache (db response)
2. check local cache (db respoonse)
3. check tiered cache (db response)
4. if non of those have the data needed, it would fetch data from a database (origin)

Response headers are showing cloudflare headers

In my worker I am fetching an external API, and ultimately need to read the headers from the response. The problem is that it keeps showing me request headers instead of the response headers.

How to redirect with new headers back to the same page?

User goes to page /foo, we check if this page is protected, if it is, we rewrite the page to something else using middleware, now this identical page has a password form. The goal is to authenticate the password, and if its correct, redirect them back to the original page with headers pretty much allowing the user to skip the rewrite in the middleware and view the protected page. Is this possible?

Are TRPC server procedures actual endpoints? Meaning can you directly do a `post` request to them?

Lets say you have a public procedure called getHelloWorld, can you hit it by doing localhost:3000/trpc/baseRouter/getHelloWorld? or something
