Killing `pnpm dev` results in a defunct `esbuild` process

I've created a fresh solid start project with the default template. I noticed that pressing Ctrl+C causes a esbuild process to linger around in the defunct state.

  11169 pts/1    Z      0:00 [esbuild] <defunct>

  11169 pts/1    Z      0:00 [esbuild] <defunct>

So every time I start and stop the process another defunct esbuild process is created. I guess this really is a vinxi or vite issue. I just wanted to ask here if anyone else ran into this issue and knows a fix.

Testing code without a render function

I was writing some utility functions using SolidJS primitives and ran into the issue that memos don't update. This is the minimal vitest where I could reproduce the issue:

test('memo', () => {
  createRoot(() => {
    const [signal, setSignal] = createSignal(false)
    const memo = createMemo(() => signal())
    expect(memo()).eq(false)
    setSignal(true)
    expect(memo()).eq(true)
  })
})

test('memo', () => {
  createRoot(() => {
    const [signal, setSignal] = createSignal(false)
    const memo = createMemo(() => signal())
    expect(memo()).eq(false)
    setSignal(true)
    expect(memo()).eq(true)
  })
})

Am I missing something?

Accessing parts of a Store (sub store, substore)

I ran into some typing issue with stores. I've got a component that expects a data: T[] and setter: SetStoreFunction<T[]> . This is all fine when passing in a complete store as created by createStore(...) but breaks down if I want to pass a part around: e.g.

<Foo
  data={store.foo}
  setter={(...args) => setStore('foo', ...args)}
/>

<Foo
  data={store.foo}
  setter={(...args) => setStore('foo', ...args)}
/>

While this does indeed work at runtime TS goes bonkers about this as is doesn't know the type of args and I can't deduce anything due to the overload of the SetStoreFunction interface. fwiw. would be a helper like subStoreSetter(store, "foo") which returns that setter function so it could be used like that:

const setFoo = subStoreSetter(setStore, 'foo')
<Foo
   data={store.foo}
   setter={setFoo}
/>

const setFoo = subStoreSetter(setStore, 'foo')
<Foo
   data={store.foo}
   setter={setFoo}
/>

While we're at it that feature could also be a member of the setStore function which would look really nice API wise:

const setFoo = setStore.sub('foo')

const setFoo = setStore.sub('foo')

I don't know if this is even possible or if I should be replacing that one store object with multiple arrays into multiple stores one per array. Maybe that feature is still around somewhere and I'm just not seeing it. 🙈

ts-node not able to resolve ~ or node imports

I've got some scripts written in TypeScript in my project which I would like to execute. After some digging ts-node seams to be the obvious choice. However neither the ~ nor the import from node itself were working. After some digging I found that I can fix the node imports by either removing the types key from the tsconfig compilerOptions altogether or adding node to the array. Regarding the ~ paths however I'm stuck. I tried adding the tsconfig-paths package which doesn't seam to work at all, tried adding imports to the package.json and switching to a #root prefix instead. Nothing seams to help and I'm stuck with the annoying error message:

CustomError: Cannot find package '~' imported from /home/bikeshedder/projects/myproject/src/scripts/gen_schema.ts
