Fill Livewire form with external data

How are you filling it using JavaScript? show some code.

If you want to fill data from API you can do so.

For inputs:

Select::make('status')
    ->options(getDataFromApi());

For tables:

public function table(Table $table): Table
{
    $apiCall = Http::asJson()
        ->acceptJson()
        ->get(config('app.url') . '/api/subscription');
 
    return $table
        // You might think this works, but it does not.
        // It's not meant for this use-case
        ->viewData($apiCall->json('data'))
        ->columns([
            TextColumn::make('user_name'),
            TextColumn::make('name'),
            TextColumn::make('price'),
            TextColumn::make('start_date'),
            TextColumn::make('end_date'),
        ]);
}

If you're using JavaScript in front-end you need to trigger $wire.set for it to reflect in Livewire.

Hi @casperbaske

Did you try to simply utilise field lifecycle hooks:
