[Compound indexes]: Query first field, then sort by _creationTime
Yeah if you care about sorting / filtering on
_creationTime and are loading enough documents that re-sorting in JS is expensive, then you probably want two separate indexes (this is in the "Exceptions" section of the best practices doc).
It's ultimately a trade off of write overhead / more storage (for more indexes) vs. query performance -- something like .all("privacyStatus") could be implemented as N separate queries, but if restricting to _creationTime to one month ago is the more important constraint, sounds like you might need an index on channelId, _creationTime in addition to channelId, privacyStatus
https://stack.convex.dev/databases-are-spreadsheets is how I visualize what can and can't be done efficiently with an index (e.g. why all would have to be N separate queries)3 replies

Can't start a local deployment
^^ that -- it's a regression (both hitting it if you're not using node actions, and the lack of error message) and already on its way to being fixed, but in the meantime setting your node version to v18 will probably unblock you

Convex function logging
Agree that a bunch of this would be useful! I want to point out that you can actually build a lot of this yourself (if you don't want to wait on us).
You can add middleware with
customFunctions to at least log the arguments (I don't see a super easy way to do it for return values at the moment). And you can get toggle-able logging that's configurable per instance by wrapping console.log and gating the log on an environment variable (here is something I did for one of my own apps, we've been doing some similar stuff for Convex components we author too example)10 replies

Deployment error
Do you have any environment variables set on your dev deployment that might need to also get set in your prod deployment?
This error looks like it could be something like
new Stripe() being called somewhere in your Convex code, and under the hood it's reading an environment variable that isn't set in your production Convex deployment (but probably is set in your Convex dev deployment since I'm guessing you got this working there before deploying)3 replies

Yeah looks like this is a regression (both that now every project requiring Node 18 + there being no good error message), so thank you for raising it. Looking into fixing that now

Ah gotcha. Hopefully Node 18 helps -- there's also some changes in the pipeline that might make it easier to spin up a local backend from the CLI

Convex Local Dev Deployments failing
Hmm. So a couple things you can do:
* Can you check that you're running Node 18? (
node --version) -- I think we've had issues around that in the past, but thought we fixed it to print a better error message
* If that doesn't work, to get you unblocked, you can opt out (npx convex disable-local-deployments) and then you'll be running against a cloud deployment (which should definitely work)12 replies

npx convex dev is the thing running the local deployment, so you need to keep that running (i.e. remove the --once) to be able to connect to it12 replies

unable to push deployment
Yeah the common cases are a weird validator in your schema (I've seen stuff like
v.object({ field: "foo" }) instead of v.object({ field: v.literal("foo") }) as an example) or sometimes this happens if there are multiple versions of Convex floating around (like if you're using convex-helpers), in which case updating all the convex-related node modules usually helps7 replies

Tips on sending batch notifications to a large group of users at once?
Makes sense to not use the component if you already have tokens stored (but also migrating shouldn't be too hard if you ever want to), but it might be a good source of inspiration for sending batched notifications (I don't think I used
expo-server-sdk in the component and just hit their API with a fetch, but idk what niceties the sdk provides)
There aren't limits specific to crons, but an action can run at most 10 minutes. As erquhart said, if you do self scheduling functions, you'll never have to worry about the 10 min action limit. Yet another approach is to do self scheduling mutations, which load a batch, schedule an internal action to send the notifications, then schedules itself. Mutations get automatically and safely retried on failure, so you have a better shot of all your notifications getting delivered (vs. if one of your actions fails in one of the first few batches, you might fail to handle all the rest of the data)13 replies

Tips on sending batch notifications to a large group of users at once?
Just checking that you've seen https://github.com/get-convex/expo-push-notifications
Paginating sounds good here (probably by something like
_creationTime so you can make sure you get all the users even if the data changes between fetching pages). Sounds like you already know that Expo has a batch API for sending push notifications which you want to use.
One way to do this is with a mutation that fetches a page of data, kicks off the internal action, and then schedules itself to run again with a cursor13 replies

Self Hosted Auth
when I click on the button that calls the signin function, the call immediately fails because it tries to reach my nextjs /api/auth endpoint instead of the convex http action /api/auth endpointWhen using Next.js, it's expected that your frontend hits the nextjs
/api/auth endpoints, but these should get proxied to your Convex deployment via middleware (https://labs.convex.dev/auth/setup#middleware, under "Set up the React provider" under the "Next.js" tab), so this sounds like it's doing the right thing so far.
Adding verbose logs to your middleware will probably give more information on what's happening (https://labs.convex.dev/auth/debugging#nextjs-middleware)8 replies

Your file is called

We should... probably print some better debugging info here because it took me a while to spot it 😅5 replies

Not exactly, but if you write some tests with

const v2 = v.array(v.union(v.literal("sunday"), v.literal("monday"), ...)) would match values like ["monday"] and ["saturday", "sunday"] and ["monday", "monday", "tuesday"] (but not "monday" since it's not an array, or ["monday", "foo"] since "foo is not in the union)6 replies
