Runtime Theming 🎨

How to Use

To use this feature, simply set the FRONTEND_CSS_URL environment variable to the URL of your custom CSS file. For example:

FRONTEND_CSS_URL=http://anything/custom-style.css

Once you've set this variable, our application will load your custom CSS file and apply the styles to our frontend application.

Benefits

This feature provides several benefits, including:

• Easy customization 🔄: With this feature, you can easily customize the look and feel of our application without requiring any code changes.
• Flexibility 🌈: You can use any CSS styles you like to create a custom theme that meets your needs.
• Runtime theming ⏱️: This feature allows you to change the theme of our application at runtime, without requiring a restart or recompilation.

Example Use Case

Let's say you want to change the background color of our application to a custom color. You can create a custom CSS file with the following contents:

body {
  background-color: #3498db;
}

Then, set the FRONTEND_CSS_URL environment variable to the URL of your custom CSS file. Once you've done this, our application will load your custom CSS file and apply the styles, changing the background color to the custom color you specified.

Custom Export Templates 📄

You can define custom export templates to add introductory content, such as headers or titles, to documents before exporting them as PDF, Docx, etc...

Export Templates are managed through the admin interface and can be selected by users during the export process.

Benefits

This feature offers several advantages:

• Header customization 📄: Add custom headers, titles, or branding to exported documents.
• No code changes required 🔧: Templates are managed through the admin interface without needing developer intervention.
• Flexible content 🌟: Use HTML to create headers that match your organization's style.

Limitations ⚠️

• Currently, templates are only prepended to the document. More complex layouts are not supported at this time.
• The CSS and Description fields are being ignored at this time.
• Due to technical conversion limitations, not all HTML can be converted to the internal format!

How to Use

1. Create the Template in a new document.
2. Copy it as HTML code using the Copy as HTML feature:
3. Log in to the admin interface at /admin (backend container).
4. Create a new template:
   • Title: Enter a descriptive name for the template.
   • Code: Paste the HTML content from step 2.
   • Public: Check this box to make the template available in the frontend export modal.
   • Save the template.

Once saved, users can select the template from the export modal in the frontend during the export process.
