null values in nuxt ui input

Hi there! It looks like after a recent change of something, nuxt ui no longer allows certain values in a UInput's v-model? I get the following error when trying to display a possible null value in an input

Type 'string | null | undefined' is not assignable to type 'string | number | undefined'

Type 'string | null | undefined' is not assignable to type 'string | number | undefined'

It also appears that boolean options are no longer allowed in select menus either... Or an array of strings? Though that might be due to the null value

Type 'string[] | null | undefined' is not assignable to type 'string | 
number | Record<string, any> | unknown[] | undefined'.

Type 'string[] | null | undefined' is not assignable to type 'string | 
number | Record<string, any> | unknown[] | undefined'.

If this change was intentional there a correct way to handle these kinds of data errors? It might just be a bad implementation my end if I'm using boolean values in select's for example I am using @nuxt/ui: ^2.14.2. The error is also present on ^2.15.2 which is the latest version The code used to build fine so I'm not sure what changed I'm also really confused as I only get the errors when running nuxi typecheck, but not in my local vscode Maybe it was an update to vue-tsc?

Hell I can't even use a boolean anymore it seems with a USelectMenu?

<script setup lang="ts">

const value = ref<boolean|undefined>();

const options = [
  {
    label: 'Yes',
    value: true
  },
  {
    label: 'No',
    value: false
  },
  {
    label: 'None selected',
    value: undefined
  }
];
</script>

<template>
  <div>
    <USelectMenu
    :options="options"
    v-model="value"
    value-attribute="value" option-attribute="label"
    />
  </div>
</template>

<script setup lang="ts">

const value = ref<boolean|undefined>();

const options = [
  {
    label: 'Yes',
    value: true
  },
  {
    label: 'No',
    value: false
  },
  {
    label: 'None selected',
    value: undefined
  }
];
</script>

<template>
  <div>
    <USelectMenu
    :options="options"
    v-model="value"
    value-attribute="value" option-attribute="label"
    />
  </div>
</template>

And I get this error with the v-model, where the property's type is boolean|undefined

error TS2322: Type 'boolean | undefined' is not assignable to type 'string | number | Record<string, any> | unknown[] | undefined'.

Your problem seems to be with the boolean value. No change on the component side: https://github.com/nuxt/ui/commits/dev/src/runtime/components/forms/Input.vue

Sorry I forgot to submit my edit to that message you're replying to. Added an example I'm going to raise an issue on the github, but I think it might be a problem with vue-tsc

Ohh it's a SelectMenu not a UInput

WazbatOP•7mo ago

I have similar typeerrors with both components I'm trying to set up a small proper example with a UInput now I was able to fix my inputs by type casting to string|undefined which while not ideal, works. But this here with the select is a blocker as I can't type cast my way out of it ...well I can but it's a mess and I'd rather just fix the problem Here's the same with an input. This one also doesn't compile

<script setup lang="ts">
const value = ref<string | null | undefined>(undefined);
</script>

<template>
  <div>
    <UInput v-model.trim="value" />
  </div>
</template>

<script setup lang="ts">
const value = ref<string | null | undefined>(undefined);
</script>

<template>
  <div>
    <UInput v-model.trim="value" />
  </div>
</template>

For me this example works without TS issues :

<script setup lang="ts">
type Option = {
  label: string
  value: boolean | undefined
}

const value = ref<Option['value']>()

const options: Option[] = [
  {
    label: 'Yes',
    value: true
  },
  {
    label: 'No',
    value: false
  },
  {
    label: 'None selected',
    value: undefined
  }
];
</script>

<template>
  {{ value }}

  <USelectMenu
    :options="options"
    v-model="value"
    value-attribute="value" 
    option-attribute="label"
  />
</template>

<script setup lang="ts">
type Option = {
  label: string
  value: boolean | undefined
}

const value = ref<Option['value']>()

const options: Option[] = [
  {
    label: 'Yes',
    value: true
  },
  {
    label: 'No',
    value: false
  },
  {
    label: 'None selected',
    value: undefined
  }
];
</script>

<template>
  {{ value }}

  <USelectMenu
    :options="options"
    v-model="value"
    value-attribute="value" 
    option-attribute="label"
  />
</template>

Yeah that one doesn't work for me on my local. I get this error

What version of vue-tsc are you using?

Valentin•7mo ago

https://stackblitz.com/edit/nuxt-ui-gyskbt?file=package.json Nuxt ui 2.15.2 https://nuxt.com/docs/guide/concepts/typescript @Wazbat

You may experience issues with the latest vue-tsc and vite-plugin-checker, used internally when type checking. For now, you may need to stay on v1 of vue-tsc, and follow these upstream issues for updates: fi3ework/vite-plugin-checker#306 and vuejs/language-tools#3969.
