The react-markdown dependency chain uses Node.js subpath imports
(vfile/lib/#minpath) that Sandpack's bundler cannot resolve, breaking
markdown artifact preview. Switch to a self-contained static HTML page
using marked.js from CDN, eliminating the React bootstrap overhead and
the problematic dependency resolution.
* 🛡️ fix: Sanitize markdown artifact rendering to prevent stored XSS
Replace marked-react with react-markdown + remark-gfm for artifact
markdown preview. react-markdown's skipHtml strips raw HTML tags,
and a urlTransform guard blocks javascript: and data: protocol links.
* fix: Update useArtifactProps test to expect react-markdown dependencies
* fix: Harden markdown artifact sanitization
- Convert isSafeUrl from denylist to allowlist (http, https, mailto, tel
plus relative/anchor URLs); unknown protocols are now fail-closed
- Add remark-breaks to restore single-newline-to-<br> behavior that was
silently dropped when replacing marked-react
- Export isSafeUrl from the host module and add 16 direct unit tests
covering allowed protocols, blocked schemes (javascript, data, blob,
vbscript, file, custom), edge cases (empty, whitespace, mixed case)
- Hoist remarkPlugins to a module-level constant to avoid per-render
array allocation in the generated Sandpack component
- Fix import order in generated template (shortest to longest per
AGENTS.md) and remove pre-existing trailing whitespace
* fix: Return null for blocked URLs, add sync-guard comments and test
- urlTransform returns null (not '') for blocked URLs so react-markdown
omits the href/src attribute entirely instead of producing <a href="">
- Hoist urlTransform to module-level constant alongside remarkPlugins
- Add JSDoc sync-guard comments tying the exported isSafeUrl to its
template-string mirror, so future maintainers know to update both
- Add synchronization test asserting the embedded isSafeUrl contains the
same allowlist set, URL parsing, and relative-path checks as the export
* refactor: Code Editor and Auto Scroll Functionality
- Added a useEffect hook in CodeEditor to sync streaming content with Sandpack without remounting the provider, improving performance and user experience.
- Updated useAutoScroll to accept an optional editorRef, allowing for dynamic scroll container selection based on the editor's state.
- Refactored ArtifactTabs to utilize the new editorRef in the useAutoScroll hook, ensuring consistent scrolling behavior during content updates.
- Introduced stableFiles and mergedFiles logic in CodeEditor to optimize file handling and prevent unnecessary updates during streaming content changes.
* refactor: Update CodeEditor to Sync Streaming Content Based on Read-Only State
- Modified the useEffect hook in CodeEditor to conditionally sync streaming content with Sandpack only when in read-only mode, preventing unnecessary updates during user edits.
- Enhanced the dependency array of the useEffect hook to include the readOnly state, ensuring accurate synchronization behavior.
* refactor: Monaco Editor for Artifact Code Editing
* refactor: Clean up ArtifactCodeEditor and ArtifactTabs components
- Removed unused scrollbar styles from mobile.css to streamline the code.
- Refactored ArtifactCodeEditor to improve content synchronization and read-only state handling.
- Enhanced ArtifactTabs by removing unnecessary context usage and optimizing component structure for better readability.
* feat: Add support for new artifact type 'application/vnd.ant.react'
- Introduced handling for 'application/vnd.ant.react' in artifactFilename, artifactTemplate, and dependenciesMap.
- Updated relevant mappings to ensure proper integration of the new artifact type within the application.
* refactor:ArtifactCodeEditor with Monaco Editor Configuration
- Added support for disabling validation in the Monaco Editor to improve the artifact viewer/editor experience.
- Introduced a new type definition for Monaco to enhance type safety.
- Updated the handling of the 'application/vnd.ant.react' artifact type to ensure proper integration with the editor.
* refactor: Clean up ArtifactCodeEditor and mobile.css
- Removed unnecessary whitespace in mobile.css for cleaner code.
- Refactored ArtifactCodeEditor to streamline language mapping and type handling, enhancing readability and maintainability.
- Consolidated language and type mappings into dedicated constants for improved clarity and efficiency.
* feat: Integrate Monaco Editor for Enhanced Code Editing Experience
- Added the Monaco Editor as a dependency to improve the code editing capabilities within the ArtifactCodeEditor component.
- Refactored the handling of TypeScript and JavaScript defaults in the Monaco Editor configuration for better type safety and clarity.
- Streamlined the setup for disabling validation, enhancing the artifact viewer/editor experience.
* fix: Update ArtifactCodeEditor to handle null content checks
- Modified conditional checks in ArtifactCodeEditor to use `art.content != null` instead of `art.content` for improved null safety.
- Ensured consistent handling of artifact content across various useEffect hooks to prevent potential errors when content is null.
* fix: Refine content comparison logic in ArtifactCodeEditor
- Updated the condition for checking if the code is not original by removing the redundant null check for `art.content`, ensuring more concise and clear logic.
- This change enhances the readability of the code and maintains the integrity of content comparison within the editor.
* fix: Simplify code comparison logic in ArtifactCodeEditor
- Removed redundant null check for the `code` variable, ensuring a more straightforward comparison with the current update reference.
- This change improves code clarity and maintains the integrity of the content comparison logic within the editor.
