apps/client/src/features/viewers/pop-out-clock/PopOutTimer.scss (4)
1-15: LGTM! Consider using viewport units for width.The import and main container styles are well-structured and follow best practices. The use of CSS variables and Grid layout is commendable.
For improved responsiveness, consider using
width: 100vw;instead ofwidth: 100%;to ensure the timer spans the full viewport width, including any potential scrollbar space.
16-20: Specify transition properties for better performance.The finished state styles are well-implemented, especially the use of
clamp()for responsive sizing.To optimize performance, specify which properties should transition:
- transition: $viewer-transition-time; + transition: outline $viewer-transition-time, outline-offset $viewer-transition-time;This change ensures only the relevant properties are animated, potentially improving rendering performance.
22-41: LGTM! Consider adding a minimum font size for better readability.The timer styles are well-implemented, with good use of CSS variables and responsive units.
To ensure readability on very small screens, consider adding a minimum font size:
- font-size: 20vw; + font-size: clamp(24px, 20vw, 200px);This change ensures the timer text doesn't become too small on narrow viewports while maintaining its responsive nature.
43-53: LGTM! Consider using a CSS variable for consistency.The end message styles are well-implemented, providing a clear and prominent display when the timer ends.
For consistency with the timer styles and easier customization, consider using a CSS variable for the color:
- color: $timer-finished-color; + color: var(--timer-finished-color-override, $timer-finished-color);This change allows for easy overriding of the end message color while maintaining the default from the SCSS variable.
apps/client/src/features/viewers/pop-out-clock/PopOutTimer.options.ts (2)
5-21: Consider clarifying the "Hide Overtime" description.The "Timer Options" and "Element visibility" sections are well-organized. However, the description for the "Hide Overtime" option could be more precise.
Consider updating the description to clarify that it affects both visual styles:
- description: 'Whether to suppress overtime styles (red borders and red text)', + description: 'Whether to suppress overtime styles (hides both red borders and red text)',This change makes it explicit that both visual elements are affected by this option.
54-91: LGTM: Comprehensive positioning options with a minor suggestion.The alignment and offset options provide excellent control over the timer's appearance and position. The use of predefined values for alignment enhances usability.
Consider updating the vertical alignment description for accuracy:
- description: 'Moves the vertically in page to start = left | center | end = right', + description: 'Moves vertically in page to start = top | center | end = bottom',This change corrects the directional terms for vertical alignment, improving clarity for users.

- interface MinimalTimerProps { - isMirrored: boolean; time: ViewExtendedTimer; viewSettings: ViewSettings; } ... - const { isMirrored, time, viewSettings } = props; + const { time, viewSettings } = props;
50-68: Variableclickedis not used; consider removing itThe
clickedvariable is set totruewhenopenPipis called but isn't used elsewhere in the component. If it's intended for future use, please implement the functionality. Otherwise, consider removing it to clean up the code.Apply this diff to remove the unused variable:
- let clicked = false; ... const openPip = async () => { if (!videoRef.current) return; - clicked = true; await videoRef.current.play();

Fix inconsistency in text color placeholder.
The "View style override" section is well-structured, providing comprehensive customization options. However, there's an inconsistency in the text color placeholder.
Apply this change to fix the inconsistency:
- placeholder: 'fffff (default)',
+ placeholder: 'ffffff (default)',This change ensures that the placeholder represents a valid 6-digit hexadecimal color code, consistent with the other color options.

🛠️ Refactor suggestion
Consider refactoring hardcoded values in PopOutTimer props.
While the placement of the PopOutTimer component is correct, there are a few points to consider:
- The
timeprop contains many hardcoded values. This could lead to maintenance issues and might not reflect the actual state of the application. - The
viewSettingsprop has empty strings for colors and messages.
Given that this is a proof of concept, these issues are understandable. However, for the next iteration, consider:
- Connecting the
timeprop to your application's state management system (e.g., Redux, Context API) to reflect real-time values. - Implementing a configuration file or environment variables for the
viewSettingsto make them easily customizable. - Adding PropTypes or TypeScript interfaces to define the expected prop types and structures.
Would you like assistance in setting up a more dynamic prop structure for the PopOutTimer component?

Variables color and title are not updated; consider removing or updating them
In the useEffect hook, changeVideo is called with color and title, but these variables are not updated anywhere in the component. As a result, the video might not display the intended content.
If color and title are meant to change based on certain conditions or props, ensure they are updated accordingly. Otherwise, consider removing them if they are not needed.

🛠️ Refactor suggestion
Consider updating the useEffect to handle changes in time
The display value is derived from time, and if time changes, the interval may not reflect the updated timer. Consider updating the useEffect to handle changes in time to ensure the timer stays accurate.
Update the dependency array and adjust the effect:
- }, [ready, display]);
+ }, [ready, time]);Committable suggestion was skipped due to low confidence.
Include dependencies in the useEffect hook to prevent stale values
The useEffect hook depends on display, which is derived from time and may change over time. Currently, the dependency array only includes [ready], which could lead to the interval using stale values of display.
Consider adding display or its dependencies to the dependency array to ensure the interval reflects the latest timer values.

🛠️ Refactor suggestion
Optimize video generation by using a continuous stream instead of creating blobs repeatedly
Currently, createVideoBlob is called every second, creating a new video blob each time. This approach is inefficient and may cause performance issues.
Consider using the canvas stream directly as the source for the video element without creating new blobs. This can be achieved by assigning the canvas stream to the video element's srcObject.
Apply this diff to refactor the video handling:
- createVideoBlob(canvas, context, (newVideoSource) => {
- if (videoSource) {
- URL.revokeObjectURL(videoSource);
- }
- setVideoSource(newVideoSource);
- videoElement.src = newVideoSource;
- videoElement.play().catch((error) => {
- console.error("Error playing video:", error);
- });
- });
+ const stream = canvas.captureStream(30);
+ videoElement.srcObject = stream;
+ videoElement.play().catch((error) => {
+ console.error("Error playing video:", error);
+ });Committable suggestion was skipped due to low confidence.
💡 Codebase verification
Proper Cleanup of Media Resources is Not Fully Implemented
- In
apps/client/src/features/viewers/pop-out-clock/PopOutTimer.tsx, theURL.createObjectURLis used to create a blob URL but is never revoked usingURL.revokeObjectURL, which can lead to memory leaks. - Additionally, ensure that the media stream obtained from
canvas.captureStreamis explicitly stopped after usage to release all associated resources.

Ensure proper cleanup of media resources to prevent memory leaks

Avoid using let for variables that persist across renders; use useState or useRef instead
The variables color, title, and clicked are declared with let and are re-initialized on every render. This means they won't retain any changes between renders, which may lead to unexpected behavior.
To maintain their values across renders, consider using useState or useRef. Additionally, if title and clicked are not being updated or used elsewhere in the component, they might be unnecessary.
Apply this diff to fix the issue:
- let color = "#000000";
- let title = "";
- let clicked = false;
+ const colorRef = useRef("#000000");
+ const titleRef = useRef("");
+ const clickedRef = useRef(false);📝 Committable suggestion

| let clicked = false; | |
| const colorRef = useRef("#000000"); | |
| const titleRef = useRef(""); | |
| const clickedRef = useRef(false); | |
| ``` | |
| This suggestion replaces the original `let` declarations with `useRef` hooks, which will allow the values to persist across renders. The suggestion is complete and can be directly applied to replace the original code snippet. | |
| Note: To use `useRef`, make sure to import it from 'react' at the top of the file if it's not already imported: | |
| ```typescript | |
| import { useRef } from 'react'; |
