SolidJS UI library + Astro

Hey, would anyone happen to have experience using a UI library together with Astro? I can get it working if I just export some simple components, but if I then add an import to another SolidJS library (eg. @kobalte/core or @ark-ui/solid to help build my primitives), then I run into:

The requested module 'solid-js/web' does not provide an export named 'effect'

The requested module 'solid-js/web' does not provide an export named 'effect'

At first I was using tsup with tsup-preset-solid, but at this point I’ve tried almost everything I can think of: rollup, vite, esbuild, or just plain tsc. On the other hand, tried a bunch of different Astro configs, but no matter what I do I can’t get past this error. Are there any example projects with such a setup somewhere?

❔ Output to console if run from console - otherwise do not create console window?

I've got an Windows app that doesn't have a UI. I'd like to not have a console window opened when it's launched fron File Explorer, but if the user launches the app from a terminal (eg. ./myapp.exe), then I'd want Console.WriteLine calls (for debugging) to go to that terminal window. Is there some way to achieve this? If I set the OutputType to Exe, then it spawns a console window when launched from File Explorer. However, when run from a terminal window, the behavior is correct - Console.WriteLine output goes to that existing terminal window. If I set the OutputType to WinExe, the behavior is correct when launched from File Explorer - no console window is spawned. However, when run from a terminal window, Console.WriteLine calls don't appear at all

Manually mounting SolidJS component within HTML component via `render`

I'm on an adventure of doing some truly weird shit. I'm parsing YAML and dynamically creating HTML and inserting SolidJS components based on the template properties below:

group/main:
  template: |
    <div class="main">
      {{ widgets }}
    </div>
  widgets:
    - type: 'clock'
      template: |
        <div class="clock">
          {{ hours }}:{{ minutes }}
        </div>

group/main:
  template: |
    <div class="main">
      {{ widgets }}
    </div>
  widgets:
    - type: 'clock'
      template: |
        <div class="clock">
          {{ hours }}:{{ minutes }}
        </div>

(The user is the one who writes the YAML and runs the app, so it doesn't matter if it's insecure and dangerous) How I'm getting this to work currently:

export function ClockWidget(props) {
  const [date, setDate] = createSignal(new Date());

  const minutes = createMemo(() => date().getMinutes());
  const hours = createMemo(() => date().getHours());
  const interval = setInterval(() => setDate(new Date()), 1000);

  // Create an `HTMLElement` from `props.template`.
  const element = getParsedTemplate();

  createEffect(
    on(
      () => [hours(), minutes()],
      // When the hours/minutes change, re-parse the template and mutate
      // the original HTMLElement in-place to match the new template. Maybe there's
      // some better way to do this?
      () => diffAndMutate(element, getParsedTemplate()),
    ),
  );

  function getParsedTemplate() {
    return parseTemplate(props.template, { // props.template is a string `<div class="clock">{{ hours }} ...`
      bindings: {
        strings: {
          hours: hours(),
          minutes: minutes(),
        },
      },
    });
  }

  return element; // This does not return JSX; it returns a regular `HTMLElement`.
}

export function Group(props) {
  // Create an `HTMLElement` from `props.template`.
  return parseTemplate(props.template, {
    bindings: {
      components: {
        // Hardcode clock widget to be the only widget for this example.
        widgets: () => (
          <ClockWidget template={props.widgets[0].template} />
        ),
      },
    },
  });
}

export function ClockWidget(props) {
  const [date, setDate] = createSignal(new Date());

  const minutes = createMemo(() => date().getMinutes());
  const hours = createMemo(() => date().getHours());
  const interval = setInterval(() => setDate(new Date()), 1000);

  // Create an `HTMLElement` from `props.template`.
  const element = getParsedTemplate();

  createEffect(
    on(
      () => [hours(), minutes()],
      // When the hours/minutes change, re-parse the template and mutate
      // the original HTMLElement in-place to match the new template. Maybe there's
      // some better way to do this?
      () => diffAndMutate(element, getParsedTemplate()),
    ),
  );

  function getParsedTemplate() {
    return parseTemplate(props.template, { // props.template is a string `<div class="clock">{{ hours }} ...`
      bindings: {
        strings: {
          hours: hours(),
          minutes: minutes(),
        },
      },
    });
  }

  return element; // This does not return JSX; it returns a regular `HTMLElement`.
}

export function Group(props) {
  // Create an `HTMLElement` from `props.template`.
  return parseTemplate(props.template, {
    bindings: {
      components: {
        // Hardcode clock widget to be the only widget for this example.
        widgets: () => (
          <ClockWidget template={props.widgets[0].template} />
        ),
      },
    },
  });
}

Losing reactivity in props passed to `children` callback

I've got a component Field that passes a memo to props.children. I'm running into an issue where the child component is not updating on changes to the memo

export function Field(props: { form: Form; children: JSXElement }) { // `Form` is a SolidJS store
  const fieldState = createMemo(() => {
    return {
      value: store.value,
      isDisabled: store.isDisabled,
      isRequired: store.isRequired,
      hasError: store.hasError,
    };
  });

  createEffect(() => console.log('Changed', fieldState()); // Is logging successfully on changes

  return props.children(fieldState());
}

// ---------------------------
<Field form={myForm}>
  {(fieldState) => (
    <>
      <p>{JSON.stringify(fieldState)}</p> // !! Not updating on changes
      <CustomInput {...fieldState} /> 
    </>
  )}
</Field>

export function Field(props: { form: Form; children: JSXElement }) { // `Form` is a SolidJS store
  const fieldState = createMemo(() => {
    return {
      value: store.value,
      isDisabled: store.isDisabled,
      isRequired: store.isRequired,
      hasError: store.hasError,
    };
  });

  createEffect(() => console.log('Changed', fieldState()); // Is logging successfully on changes

  return props.children(fieldState());
}

// ---------------------------
<Field form={myForm}>
  {(fieldState) => (
    <>
      <p>{JSON.stringify(fieldState)}</p> // !! Not updating on changes
      <CustomInput {...fieldState} /> 
    </>
  )}
</Field>

It works totally fine if I instead have several memos though:

export function Field(props: { form: Form; children: JSXElement }) {
  const fieldState = {
    value: createMemo(() => store.value),
    isDisabled: createMemo(() => store.isDisabled),
    ...
  };

  return props.children(fieldState);
}

// ---------------------------
<Field form={myForm}>
  {(fieldState) => (
    <>
      <p>{JSON.stringify(fieldState)}</p> // Updating correctly now
      <CustomInput value={fieldState.value()} isDisabled={fieldState.isDisabled()} ... /> 
    </>
  )}
</Field>

export function Field(props: { form: Form; children: JSXElement }) {
  const fieldState = {
    value: createMemo(() => store.value),
    isDisabled: createMemo(() => store.isDisabled),
    ...
  };

  return props.children(fieldState);
}

// ---------------------------
<Field form={myForm}>
  {(fieldState) => (
    <>
      <p>{JSON.stringify(fieldState)}</p> // Updating correctly now
      <CustomInput value={fieldState.value()} isDisabled={fieldState.isDisabled()} ... /> 
    </>
  )}
</Field>

a downside with the working example is having to pass in all props explicitly instead of just spreading em (ie. {...fieldState}) 😬 how come the reactivity is lost? is there a way to preserve reactivity + still being able to spread the props?

updating a tree of nodes in a SolidJS store

hey y'all. i'm trying to build a tree view where nodes have an isExpanded state i'm having a tough time trying to update the corresponding node. below is the approach i've tried but it doesn't trigger a component update for whatever reason. if there's a totally different way to do this, then i'm all ears

type Node = {
  id: string;
  isExpanded: boolean;
  children: Node[];
}

export function useTreeState() {
  const [treeState, setTreeState] = createStore<Node[]>([]);

  function setNodeExpansion(id: string, isExpanded: boolean): void {
    setTreeState(
      produce(tree => {
        // Traverse down to get the node to update.
        const foundNode = getNodeDeep(styleTree, id);
        foundNode.isExpanded = true; // <---- this doesn't actually update
        return tree;
      }),
    );
  }
}

type Node = {
  id: string;
  isExpanded: boolean;
  children: Node[];
}

export function useTreeState() {
  const [treeState, setTreeState] = createStore<Node[]>([]);

  function setNodeExpansion(id: string, isExpanded: boolean): void {
    setTreeState(
      produce(tree => {
        // Traverse down to get the node to update.
        const foundNode = getNodeDeep(styleTree, id);
        foundNode.isExpanded = true; // <---- this doesn't actually update
        return tree;
      }),
    );
  }
}

parent route with redirect (solid-router)?

is there a way to define a parent route that redirects to a child route? eg. say with the below route config, is there a way to set up a redirect from /home -> /home/browse?

<Route path="/home" component={Home}>
  <Route path="/browse" component={Browse} />
  <Route path="/projects" component={Projects} />
</Route>

<Route path="/home" component={Home}>
  <Route path="/browse" component={Browse} />
  <Route path="/projects" component={Projects} />
</Route>

Confusion around solid-query

coming from Angular, so I'm new to both solidJS and solid-query/react-query, when writing a useAuth hook, how would you go about fetching and storing the initial session?

export const useAuth = () => {
  const [session, setSession] = createSignal<Session | null>(null);

  /** Instance of auth client. */
  const { auth } = createClient();

  const initialSession = () => {
    return createQuery({
      queryKey: () => ['getSession'],
      queryFn: () => auth.getSession().then(res => res.session),
    });
  };

  setSession(initialSession()?.data ?? null); // <- this doesn't work as expected
  
  return { session }
}

export const useAuth = () => {
  const [session, setSession] = createSignal<Session | null>(null);

  /** Instance of auth client. */
  const { auth } = createClient();

  const initialSession = () => {
    return createQuery({
      queryKey: () => ['getSession'],
      queryFn: () => auth.getSession().then(res => res.session),
    });
  };

  setSession(initialSession()?.data ?? null); // <- this doesn't work as expected
  
  return { session }
}

Monorepo error with SolidStart `__vite_ssr_import_0__.template is not a function`

I've got a shared UI library (compiled into esm + cjs with vite) that is used with both a regular SolidJS app and a SolidStart app. It's working fine in the SolidJS app, but when importing the lib in the SolidStart app, I'm getting a pretty cryptic error:
