Tracking document changes

I'm porting data and logic for our business systems from Airtable to a custom app powered by Convex. Part of what Airtable provides as a standard feature is record history. This history has proved invaluable in solving problems that come up on occasion, so I need to replicate this in the new system. I'm thinking that storing all changes in a separate table would be the way to go, with an ID field indexed to make searching for changes to a given document more efficient, and the app to use pagination to optimize the query process. The main thing that I'm struggling with is how to identify and collect the change data. We have dozens of tables, and we'll need this history tracked on each of their documents. I really don't relish the idea of building that many separate history trackers. I'm thinking that some kind of "diff" helper function would be useful. I could pass it any document along with the changes to be saved to that document, and it would return the difference between the two as an object that I could stringify and save to the history table....

Is there limitations on the dev cloud environment, or is it safe to use it for prototypes?

I don't need the separation of prod/dev right now and my usage doesn't need a lot of resources. The deploy on save of the dev environment is really powerful 😅...

Broken IDs: Find and Eliminate

Because of some situations and not creating cascading deletes, I've got some IDs littered throughout my database that are no longer pointing to a real row. In the dashboard it is clear because the link is broken, but I'm hoping to find a way to efficiently get rid of those. Is there an article or helper that has been created that can help me eliminate those? Surely I'm not the only one who has run into this....

Unable to access identity from ctx.auth.getUserIdentity in HTTP action

Hi team, I'm trying to secure my image upload HTTP action and currently call the action via a hook. I'm using Clerk for auth and was able to confirm that calling useAuth() then awaiting the getToken function returns a JWT token. When I pass this token in as an Authorization header to my call to my HTTP action and then call ctx.auth.getUserIdentity() within the action, I keep seeing null. Any ideas what may be going on here? Thanks!...

Infinite Scrolling with TanStack Query & Convex – Is It Possible?

Guys, is it possible to use TanStack Query with Convex for pagination (specifically for infinite scrolling)? Can I get an example repo to look at or some documentation links? Thank you so much!

middleware is slowing down NextJS page render

after few hours of debugging, i finally figured out why my Next app page navigation is slow (doesnt instantly navigate when clicking <Link/>). It was the convexAuth.isAuthneticated() function is triggered on every page navigation. I know it was the function because when i remove the line, my page navigates to the new path instantly and i dont have that auth:isAuthenticated log in convex. so the question is how do i optimize it ??...

Mapping telegram user ids to Convex users

is there a way to just tell Convex "this user is authenticated" and then call the actions and have ctx.auth.getUserIdentity() return the user? I have a use case for telegram bot where I am looking up user by their telegram user id and then calling the actions that depend on ctx.auth.getUserIdentity(). I want to avoid the need to pass telegram user id to the convex actions and want to have the same experience for telegram users as a user calling via convex react client....

ConvexQueryCacheProvider in Expo?

I'm adding the following import to my Expo app: import { ConvexQueryCacheProvider } from 'convex-helpers/react/cache/provider'; and wrapping the app with <ConvexQueryCacheProvider> But somehow I still get the error message saying that this provider is missing. I'm wondering if this is supposed to work in RN/Expo?...

`.unique()`: Better error logging

Could the Convex error log Uncaught Error: unique() query returned more than one result indicate the id of a document found not to be unique? Would help us in easily identifying and correcting erroneous data! 🙂

Duplicate a File

I am trying to copying an Entity in the DB, which has a file associated to it to another user. So when a user tried to duplicate an entity, I need to: 1. Copy entity to the new user 2. If there is a file attached to it, duplicate it and attach to the new Entity created. I could not figure out how to duplicate an existing file in Convex. Any idea?...

Are there any plans for optimistic updates by default?

Hello community. I have just migrated my app from Firebase and see that all mutations are pessimistic by default in convex. This was not expected. It breaks UX in many places, like drag and drop and even droplists. Is there a reason for the default "pessimism" in Convex philosophy? Is there, by any chance, a plan to have configuration in the future to make all mutations optimistic by default? I love Convex and feel it's a dream product, but the requirements for verbose optimism make me think of...

I kept getting the below error Math that I believed should always end up with an integer was sometimes not, I am still not sure if its a weird floating point thing or an actual mistake in my logic but either way casting to an int eliminated the error const int_index = Math.floor((page - 1) * pageSize); const { key } = await timeline_aggregate.at(ctx, int_index);...

Unconventional Authentication Implementation

I have an interesting client and one of his specifications is that he wants to keep users of the platform completely anonymous, but we still need a way to identify them, but without knowing their personal details. So he wants to use phone numbers to authenticate them and they encrypt the phone number in the database I don't really know how to go about implementing this with convex. The 2 ideas I have are: 1. To use the Lucia implementation to create a custom auth flow - but lucia is deprecated so I have to find the equivalent....
