Step 1: Set Up Markdown Editor

Begin by integrating a markdown editor into your Livewire component's view for creating blog posts with rich text formatting:

<x-markdown wire:model="content" />

This Markdown editor setup allows users to input content using markdown syntax and binds the input to the Livewire component.

Step 2: Capture Blog Post Title

Create an input field to capture the title of the blog post within your Livewire component's view:

<input type="text" wire:model="title" class="form-control" placeholder="Enter the title" />

This input field lets users enter the title of the blog post, which will be stored along with the post content.

Step 3: Save Blog Post Data

Implement the logic to save the blog post data (title and content) to the database upon submission:

public function savePost()
{
    $post = new Post;
    $post->title = $this->title;
    $post->content = $this->content;
    $post->save();
}

The savePost method creates a new blog post instance, assigns the title and content from Livewire component data, and saves it to the database.

Step 4: Display Success Message

Show a success message to the user upon successful blog post creation:

@if ($successMessage)
    <div class="alert alert-success" role="alert">
        {{ $successMessage }}
    </div>
@endif

This conditional statement displays a success message when the $successMessage variable is set, providing feedback to the user.

Step 5: Validate Blog Post Fields

Implement validation rules for the blog post title and content before saving them to ensure data integrity:

protected $rules = [
    'title' => 'required',
    'content' => 'required',
];

These validation rules ensure that both the blog post title and content fields are required before proceeding with saving the post.

Step 6: Handle Markdown Rendering

Render the blog post content with markdown syntax in your Livewire view to display formatted content:

<div class="post-content">
    {!! $post->content !!}
</div>

The {!! $post->content !!} directive renders the stored markdown content as HTML for a visually pleasing blog post display.

Step 7: Edit Existing Blog Posts

Enable users to edit existing blog posts by loading the post data into the editor for modification:

public function editPost($postId)
{
    $this->post = Post::find($postId);
    $this->title = $this->post->title;
    $this->content = $this->post->content;
}

The editPost method fetches the existing blog post based on the ID and prepopulates the title and content fields for editing.

Step 8: Update Blog Post Content

Implement the update logic to modify the blog post title and content and persist the changes to the database:

public function updatePost()
{
    $this->post->title = $this->title;
    $this->post->content = $this->content;
    $this->post->save();
}

The updatePost method updates the existing blog post's title and content fields with the modified values and saves the changes to the database.

Step 9: Delete Blog Posts

Allow users to delete blog posts by implementing a method to delete the selected post from the database:

public function deletePost($postId)
{
    Post::find($postId)->delete();
}

The deletePost method locates and deletes the blog post based on the provided ID, removing it from the database.

Step 10: Handle Markdown XSS Protection

Implement XSS protection for the rendered markdown content to prevent any potential security vulnerabilities:

<div class="post-content">
    {!! Purify::clean($post->content) !!}
</div>

Utilize a tool like Laravel HTMLPurifier to sanitize and clean the rendered content before displaying it to mitigate any XSS threats.

Step 11: Optimize Markdown Parsing

Enhance performance by caching parsed markdown content to reduce processing overhead during repeated renderings:

public function getProcessedContentProperty()
{
    return Cache::remember('post.content.' . $this->post->id, 60*60, function () {
        return Markdown::parse($this->post->content);
    });
}

The getProcessedContentProperty method caches the parsed markdown content for an hour, improving rendering speed for subsequent requests.
