741-896: 🛠️ Refactor suggestionAvoid storing refs in the model for potential memory leaks.
You store a text area ref (
model.textAreaRef = textAreaRef;). This can introduce memory retention issues if the model persists beyond the component’s lifecycle. A more React-friendly approach is to keep refs within the React layer, passing them down as needed, rather than storing them directly in a higher-level model object.- useEffect(() => { - model.textAreaRef = textAreaRef; - }, []); + // Keep the ref usage within the component or pass it as a prop, avoiding assignment to model

97-144:❓ Verification inconclusive
Good implementation of terminal integration.
The
handleSendToTerminalmethod provides a useful feature for sending code to terminals. However, there are a few concerns:
- The type
ContextMenuItemis used but not imported or defined in the visible code- Using
as anyforbcm.viewModelweakens type safety- The 500ms timeout in the "Create New Terminal" code path might cause race conditions if terminal initialization takes longer
Consider adding a more robust way to detect when the terminal is ready instead of using a fixed timeout:
- setTimeout(() => sendTextToTerminal(blockId, textToSend), 500); + // Option 1: Use an event listener to detect when terminal is ready + const checkTerminalReady = () => { + const terminal = getBlockComponentById(blockId); + if (terminal?.ready) { + sendTextToTerminal(blockId, textToSend); + } else { + setTimeout(checkTerminalReady, 100); + } + }; + checkTerminalReady();
🏁 Script executed:
#!/bin/bash # Check if ContextMenuItem type is defined elsewhere rg -A 2 "interface ContextMenuItem" --type typescript rg -A 2 "type ContextMenuItem" --type typescriptLength of output: 176
Below is a revised review comment. (Note: Because the previous search for a
ContextMenuItemdefinition failed due to an unrecognized file type flag, please run the following revised script manually to verify whether this type is defined elsewhere in TypeScript files.)
Enhance Terminal Integration and Type Safety
The implementation for sending code to terminals is solid overall, but please address the following points:
ContextMenuItem Type: Please verify that the
ContextMenuItemtype is imported or defined in a shared type file. If the type exists elsewhere, update the import accordingly. (The current search for its definition needs manual verification using the script above.)Type Safety: Avoid using
as anyforbcm.viewModelto ensure proper type safety. Consider refining the types instead of weakening them with a cast.Terminal Readiness: Relying on a fixed 500 ms timeout may lead to race conditions if the terminal takes longer to initialize. Instead, use a polling or event-based mechanism. For example:
- setTimeout(() => sendTextToTerminal(blockId, textToSend), 500); + const checkTerminalReady = () => { + const terminal = getBlockComponentById(blockId); + if (terminal?.ready) { + sendTextToTerminal(blockId, textToSend); + } else { + setTimeout(checkTerminalReady, 100); + } + }; + checkTerminalReady();Please verify these changes—especially ensuring that the
ContextMenuItemtype is correctly handled—to maintain a robust and type-safe implementation.
🏁 Script executed:
#!/bin/bash # Revised search for ContextMenuItem definitions in TypeScript files: rg -A 2 "interface ContextMenuItem" -g "*.ts" rg -A 2 "interface ContextMenuItem" -g "*.tsx" rg -A 2 "type ContextMenuItem" -g "*.ts" rg -A 2 "type ContextMenuItem" -g "*.tsx"Length of output: 513
Terminal Integration Improvements: Ensure Type Safety and Robust Readiness Check
The implementation is solid overall, but please address a few points:
ContextMenuItem Availability:
The type is defined infrontend/types/custom.d.ts. Ensure that its global availability is intentional. If it isn’t meant to be global, please add an explicit import infrontend/app/element/markdown.tsxfor clarity.Type Safety:
Avoid usingas anyforbcm.viewModel. Consider refining or explicitly typingviewModelso that the code remains type safe and easier to maintain.Terminal Readiness:
Relying on a fixed 500 ms timeout could lead to race conditions if the terminal initializes later than expected. A polling mechanism (or an event-based approach) can help ensure that the terminal is indeed ready before sending text. For example:- setTimeout(() => sendTextToTerminal(blockId, textToSend), 500); + const checkTerminalReady = () => { + const terminal = getBlockComponentById(blockId); + if (terminal?.ready) { + sendTextToTerminal(blockId, textToSend); + } else { + setTimeout(checkTerminalReady, 100); + } + }; + checkTerminalReady();Please verify these adjustments to ensure robust terminal integration and maintain consistent type safety.

29-36: Consider using a shared mixin or placeholder for repeated styling.You've introduced a
border-bottomproperty under.chat-msg-containerand specifically removed it for the last child. You are also adding multiple custom background manipulations in this block and others. It might be beneficial to consolidate repeated styles or color manipulation into a shared mixin or placeholder (e.g., a “divider” or “bordered-section” mixin) to maintain consistency and ease future maintenance.
47-51: Clarify padding and margin usage.The padding
14px 16px 8px;in.chat-msgmight read as top=14, left/right=16, bottom=8. Confirm that missing fourth value for left does not cause confusion for future readers, or consider using the four-value shorthand for clarity (14px 16px 8px 16px). Also, ensure thatmargin-bottom: -4px;under.chat-msg-headerwon't overlap undesirably with sibling elements.
75-101: Consolidate repeated code inside.markdown preblocks.You are repeating margin, padding,
background-color,border-radius, and text-wrapping rules in multiple.markdown preand.streaming-text .markdown prelocations. Consider consolidating these common styles under a shared rule or mixin to keep the code DRY and improve uniformity.
197-205: Ensure responsive spacing within the new input container.The new
.waveai-input-containerclass sets a background color, borders, and padding. Make sure that larger or smaller screen sizes are evaluated, because static or minimal responsiveness can hamper the user experience for text input. Consider adding responsive rules to handle narrower or larger viewports if applicable.frontend/app/view/waveai/waveai.tsx (1)
363-381: Consider clarifying prop names for clarity.
completedvs.isUpdatingmight be slightly confusing when read together. Consider renamingcompletedto something more explicit (e.g.,renderComplete) or unify the naming convention with other flags in your codebase to improve clarity.

frontend/app/element/typingindicator.tsx (3)
7-10: Clean interface definition.Good job creating and exporting a proper
TypingIndicatorPropsinterface with optional style property. This enhances reusability and type safety.
12-12: Improved component type definition.Converting to React.FC with proper type annotation improves type safety and makes the component's API clearer to consumers.
14-19: Well-structured component hierarchy.The nested structure with semantic class names improves maintainability and the visual representation of the typing indicator, making it easier to style with CSS.
frontend/app/element/typingindicator.scss (4)
4-10: Good use of flexbox layout.The flexbox layout with proper alignment, gap and padding provides a clean, responsive design for the typing indicator.
11-19: Nice bubble implementation.The bubble styling with semi-transparent background derived from accent color creates a visually appealing container for the typing dots.
21-42: Well-implemented animation sequence.The staggered animation for each dot creates a natural typing effect. Good use of CSS variables for colors and opacity values for better maintainability.
45-54: Smooth animation keyframes.The keyframes definition creates a subtle bounce effect that mimics typing. The transform and opacity changes provide a natural-looking animation.
frontend/app/element/markdown.tsx (2)
146-153: Clean implementation of text sending.The
sendTextToTerminalfunction correctly adds a newline and encodes the text in base64 before sending it to the terminal.
169-176: Well-integrated UI button.The new terminal button is properly integrated into the codeblock actions UI with appropriate icon and title.
frontend/app/element/markdown.scss (3)
129-139: Improved action buttons styling.The updated styling for codeblock actions with opacity transitions creates a cleaner, more responsive UI compared to the previous visibility approach. The backdrop blur effect adds a nice visual touch.
140-148: Good button hover interaction.The hover effect on iconbuttons provides appropriate visual feedback to users, making the interface more intuitive and responsive.
152-152: Better visibility transition.Changing from visibility to opacity allows for a smooth transition effect when showing/hiding the action buttons.
frontend/app/view/waveai/waveai.scss (1)
38-44: Evaluate the color blending approach.Declaring background colors via
rgb(from var(--highlight-bg-color) r g b / 0.07)orrgb(from var(--error-color) r g b / 0.1)is powerful, but be certain these custom properties are widely supported across your required browsers or Electron versions. You may want to confirm runtime support forrgb(from ...)syntax or provide a fallback if needed.frontend/app/view/waveai/waveai.tsx (5)
354-361: Good introduction of a typed interface for streaming text.Introducing
StreamingTextPropsclarifies your component’s contract, promoting readability and future extendibility. This looks good as a foundation for future typed expansions.
388-467: Check logic for editing user messages.The logic to remove the existing message from history (
updatedHistory = history.slice(0, msgIndex)) and then re-send it can lead to potential conversation continuity issues if there's a relevant message after the original. Confirm that it is intentional to “undo” all subsequent conversation context when editing.
485-487: Nice container classes for user/error messages.Separating
.user-msg-containerand.error-msg-containerat the container level keeps the code neatly modular, making it straightforward to manage distinct styling or behavior for each scenario. This approach looks consistent with the SCSS changes you made.
736-737: Validate the prop usage.
onButtonPressandlockedare newly introduced props. Ensure they’re tested thoroughly, especially for edge cases where the user might click the submit button multiple times or attempt to stop a request.
1066-1076: Good user-flow for the new ChatInput.You’ve wired the new
ChatInputseamlessly with “locked” status controlling the run/stop button state. Keeping this logic localized simplifies the mainWaveAicomponent’s responsibilities. Great job!
