寻求可填充HTML模板的JS UI组件，替代现有TinyMCE自制工具

Hey Pavel, let's break down some reliable, flexible alternatives that fit your exact needs—since your custom TinyMCE tool is acting up and hard to tweak, these options are built to handle template-driven editing with editable/non-editable regions and persistent template markers:

1. Handlebars + Custom Editable Controls #

This is a lightweight, fully customizable approach perfect if you don't need heavy rich text features:

• Use Handlebars-style markers like {{customerName}} or {{#nonEditable}}Company Logo{{/nonEditable}} in your base HTML template
• Write a simple parser to scan the template:
  • Replace editable markers ({{variable}}) with your custom input/select/textarea controls
  • Leave non-editable blocks as static HTML (or mark them with contenteditable="false")
• When saving, map user input values back to the template markers and preserve the original template structure
• Why it beats TinyMCE: No bloat, total control over every component's behavior (validation, formatting, etc.), and no random editor glitches messing with your template logic

2. Slate.js #

If you need a mix of rich text editing and template variable management, Slate is a highly configurable framework:

• Define custom "template variable" nodes that render as interactive controls (e.g., a clickable input field for {{invoiceNumber}})
• Set granular editable permissions: mark entire sections or individual nodes as non-editable
• Build custom behaviors from scratch—like popping up a date picker when a {{dueDate}} marker is clicked, or adding validation rules for specific variables
• Export the final content as structured JSON or HTML with your template markers intact for later use
• Why it beats TinyMCE: Slate is designed for custom editing experiences, not just generic rich text. You won't fight against pre-built editor behaviors that break your template system.

3. Framework-Based Template Editors (React/Vue) #

If you're already using a frontend framework, building a dedicated component gives you maximum control:

• For React: Create a TemplateEditor component that parses your HTML template, identifies markers, and replaces them with controlled input components
• Use state to track user inputs, and on save, inject those values back into the template string while keeping markers in place for future edits
• Mark non-editable regions by rendering them as static elements or using framework-specific props to disable editing
• Why it beats TinyMCE: You'll have full ownership over every part of the editor—no need to hack around a third-party tool's limitations.

Quick Tips to Choose #

• Go with Handlebars + custom controls if you need a simple, low-maintenance solution for variable-only template filling
• Pick Slate.js if you need rich text editing alongside template variables
• Use a framework component if you want tight integration with your existing frontend stack
