Understanding `createRoot`
5. Someone else can do this. It is for when you want to be able to manually dispose something. I can't think of any simple examples at the moment that aren't contrived. Originally ever Solid app started with a
createRoot call and you'd append the returned JSX to the DOM yourself. But now that code is wrapped in render19 replies
Understanding `createRoot`
3. The observer pattern, what Signals are, are inherently leaky. They need to link both directions between the observer and the observed. This means if one is long lived the other will never automatically be released. Like if you had a
createMemo that created another createMemo under that listened to a global Signal. Every time the outer memo reruns it would create it again. If we didn't register the inner memo to be released when the outer reran because the global Signal is never going away it would just keep accumulating subscribers on every run.
4. This is pretty advanced, similar to runWithOwner. Maybe the name is poor. It is just a way to give the root an owner for Context purposes without registering it for automatic disposal.19 replies
Understanding `createRoot`
1. Root of the ownership tree/graph. People are generally aware of the dependency graph as they see the auto tracking "magic" but we also collect reactive primitives created inside for automatic disposal. This tree is the basis of our Context solution.
2. There are 2 globals we update as we run our reactivity, our Observer(Listener) and our Owner. When we untrack we remove the listener but always have the owner. Some scopes are untracked but they are always owned. An unowned scope would be creating a reactive primitive top level or in an event handler or setTimeout.

Auth guard
Yeah I mean that is one approach.. I'm interested in what others do.. because checking against server everytime not inside things you were already fetching would cause a waterfall which isn't great (unless you were in constant contact which isn't always an option on serverless).

Auth guard
Like in one world maybe during SSR you setup some sort of access token in middleware and you pass it into a Context Provider (in a createResource/createAsync that will serialize) at the top of your page and then the client and server both have access to it. But tokens do expire so I imagine there is more logic there. Of course then you need to send the token to server to validate on API calls.. this is a classic client centric model approach.
That way it can answer the question synchronously.

Auth guard
The thing is nothing in preload will stop the page from rendering. So you have to assume on client nav after the case if you go and ask the server if you are authenticated it is still going to start rendering the new page while waiting for that answer.. sure it isn't going to get far and the Suspense/Transitions will not actually show anything to the user, before your redirect takes over.
The thing is if we ask first outside of the request it will waterfall.. so you want to ask the question inside each data (API endpoint essentially) if you can't answer the question from the client only. I always ask people what they expect to happen in these scenarios to see how it fits. Because nothing here changes the physics, just where it happens.

Yes this is the sort of thinking.. but the "true" probably needs to come from the server to verify. So my thinking is you should hoist the auth check to server middleware and then read from it inside your server functions that can then throw redirects or do the proper handling. That being said for something that isn't too granular I imagine the middleware itself could potentially handle the redirect before you are looking at specific endpoints. I believe the action methods should work even out in middleware.

crazy bug global store + solid router
I really needs some sort of reproduction on this one. Because looking at the code and what you've written to be the problem we are still missing something. The if the Transition is running then the memo will be added to it so the only places it would miss I'd think is if it isn't running and the memo isn't part of it, but then it should fine?...
