Compile Laravel blade component from string

Question

I have a pagebuilder where i store {variable} in the database. When loaded on the frontend i want the variable to be translated to blade components.

$replacers = [
  'x-system-counters' => '<x-system-counters :data="$gloabal_variable"></x-system-counters>',
  'x-system-status' => '<x-system-status :data="$gloabal_variable"></x-system-status>',
];

$page = \App\Page::first();

$text = $page->content;
foreach ($replacers as $key => $value) {
    $text = str_replace('{'.$key.'}', $value, $text);
}

//Bladefile

{!! $text !!}

Any idea of how to solve this? I have tried the Blade::compileString($text) with no luck.

Thanks

After some digging, this was actually very easy. Laravel always delivers

$replacers = [
  'x-system-status' => view('compontents.system-status', $data)->toHtml(),
];

$page = \App\Page::first();

$text = $page->content;
foreach ($replacers as $key => $value) {
    $text = str_replace('{'.$key.'}', $value, $text);
}

This works great but you have the pass the $data from the controller you are writing this into . So this will not pull the data from /app/view/components/.....

Basics

You can achieve this by following below steps:

Create a template which can be dynamic(from db or anywhere) and then replace fixed variables from that template with values. I suppose $startpage->content is the dynamic template you're trying to compile.
Replace variables with values using $startpage->content, then pass it to a simple blade with only one variable {!! $text !!}.

Solution

You can give any content you like to view function, view complies it and you can convert it to html and pass to everywhere you want.

Something like below code may help you:

$page = \App\Page::first();

$template = $startpage->content;

$desired_text = '<x-system-counters :data="$gloabal_variable"></x-system-counters>';

$text = preg_replace('/{{\$x_system_counters}}/', $desired_text, $$template)

$html = view('for_compile_view', compact('text'))->toHtml();

templates

your contents plus {{$x_system_counters}}

for_compile_view.blade.php

{!! $text !!}

Thanks for the effort, but that did't work at all. the blade components are not compiled. :(

Why? Please give more details of the errors and the results.

No errors, it's just not compiled. The element is listed in the html like this: <x-system-counters></x-system-counters> I use my loop instead of your preg_replace, becuase i have several of different components to load.
