    From docs

    If any records exist that match your query’s constraints, you may use
    the exists and doesntExist methods

    if($this->posts->where('title', $title)->doesntExist())
{
    // save
} else {
   // not save
}

    You can use first or create for saving data in database if title name is new. using firstOrNew you dont have to use any other conditions
    for example:-

    $this->posts->firstOrCreate(
['title' =>  $ite['title']],
['description'=>$ite['description'],
 'content'=>$ite['content'],
 'topic_id'=>'1',
 'post_type'=>$request->type,
 'user_id'=>'1',
 'enable'=>'1',
 'feature_image_path'=>$ite['urlToImage']]);

    firstOrNew:-
    It tries to find a model matching the attributes you pass in the first parameter. If a model is not found, it automatically creates and saves a new Model after applying any attributes passed in the second parameter
