#Basic

<Input />

#Controlled

See Controlled & Uncontrolled Components. Passing value and onInput work because of ...rest.
<Input value={value} onInput={onInput} />

#Size

Set size to either "sm", "md" or "lg". Defaults to "md".
<Stack class="w-fit gap-5">
  <Input size="sm" />
  <Input size="md" />
  <Input size="lg" />
</Stack>

#Rounded

Set rounded to either "square", "sm", "lg" or "full". Defaults to the value of the CSS variable --default-roundedness. See "Default roundedness".
<Stack class="w-fit gap-5">
  <Input rounded="square" />
  <Input rounded="sm" />
  <Input rounded="lg" />
  <Input rounded="full" />
</Stack>

#Disabled

Set disabled to either true or false. Defaults to false.
<Input disabled />

#Readonly

Set readonly to either true or false. Defaults to false.
<Input readonly value="example" />

#Invalid

Set invalid to either true or false. Defaults to false.
<Input invalid value="example" />

#Type

RFUI's Input component wraps the native HTML input and passes type to input, and so you could find the possible values documented here on MDN. If you are thinking of using number, consider taking this approach instead.
<Stack class="gap-5">
  <Input type="text" placeholder="text" />
  <Input type="email" placeholder="email" />
  <Input type="text" inputmode="numeric" pattern="[0-9]*" />
  <Input type="number" />
  <Input type="password" value="foobar" />
  <Input type="date" />
  <Input type="datetime-local" />
  <Input type="time" />
  <Input type="file" />
  <Input type="range" />
  <Input type="color" />
</Stack>

See the docs for rest parameters. For Input, you could pass anything you normally would pass to <input /> because the return value looks something like this:
<input

  {...restWithoutClass}
