How to modify array partially?

I'm using a store to store an array. I'm displaying that array in a For component. What I don't understand is how can I possibly use the "smart" feature of the For component, which only renders the changing part of the array. I mean all I can do in a store is setState(), where I put my full array in. So how can I possible send a partial update to a component? I see no way to push() at the end of an existing array in state or for example modify the last element of the array. What am I missing?...

Why does my component only update in a dummy For loop?

The component works correctly in the For loop, but doesn't do anything on it's own. ``` <For each={[props.string]}> {(t) => <Item content={t} />}...

navigate - Wait for navigation to finish

Hello, I'm reevaluating SolidJS and somehow it started really click in my head. There's one thing that I'm trying to do right now, basically I'm wrapping my whole app with UserProvider and and to expose two 'hooks' useUser and useMaybeUser with the only difference between them being that useUser would enforce that user is present or navigate you to login page. Here's what I came up with for now. ```ts import { useNavigate } from "@solidjs/router";...

Another `template2 is not a function` issue

Took a look at the other posts mentioning this issue and can't seem to find anything that helps solve the case. I have a Tab Switch component to display different JSX.Elements with. I'm about 98% sure the error is coming out of this component because when I return a simple <h1>Hej</h1> there is no template2 error. I was originally using @kobalte/core's Tabs component, then decided to try and make my own rough tab switch component. Both have produced this error and I'm not really sure how best to proceed or troubleshoot. So any guidance would be helpful....

solid-router causes error: "cleanups created outside a `createRoot` or `render` will never be run"

Hi I am relatively new to solid so I could be making a simple mistake. I recently added solid router to my solid.js project and I am using the config based approach. Since I added the router and using it I get multiple errors like this: - cleanups created outside a createRoot or render will never be run - computations created outside a createRoot or render will never be disposed Since the router is actually rendered inside the render() method of solid, I am not sure what I am doing wrong, any help how to fix the warnings would be appreciated. Below you can see my code (I also uploaded the full files because pasting entire code is higher than the discord message limit....

How to check if createMemo should be used?

I'm trying to figure out if using createMemo is or isn't worth it. I know that for super basic equality checks, there is probably no point. But what about something slow, like code highlighting?...

Exclude store property from `unwrap` or from being watched

When updating a SolidJS store, the entire next state of the store gets unwrapped (for example by updateArray()). Let's say the store is an array of objects, and each object has a data property which is a really big array. Unwrapping each of these arrays adds up to a very noticeable slow down every time the store is updated. Is there a way to exclude this property from being unwrapped, or from being "watched" by SolidJS? Thanks.

I tried using blockly as the logic editor for my app, but when I use it, nothing renders and the console doesn't print anything out. I don't know how to troubleshoot this error. I didn't find the answer on both vite and blockly issues. Can anyone help me?

Understanding Solid reactivity with console.log

I'm using createMemo with a console.log inside. Can you tell me why is this console.logging all the items, when I click on one? Am I using createMemo in a wrong way? I thought only the 2 changed items would be recalculated. I created a Stackblitz + GitHub repo to undestand this better:...

How can I tell solid router to navigate to a page by forcing a refresh, breaking the SPA

I need to send specific CORS headers on a specific page which I can only do with netlify by specifying a link and the set headers. But when they navigate to home page and then click the link, the headers is not set because home page link doesn't set the headers by netlify not configured as such. And I can't include the headers to be set on the home page as well. Because then contact page embedded video doesn't work because headers are too strict. So the easiest workaround is the force a refresh on a specific link to force the netlify configuration to work for that link specifically. Basically I need something like this:...

Can I Block All Back Navigation?

With A or useNavigation(), I can set replace: true to remove the most recently visited page from the browser history. But this doesn't block back navigation. If I click back, I skip the most recent page and go to the page that was visited before the page I just came from. Is there any way that I can block all back navigation on a specific page?...
