demo/changepoint.worker.js (1)
1-3: Consider using npm package instead of local dist fileImporting from a
distdirectory suggests using a local copy of the library. Consider installing@bsull/augursvia npm and importing it directly for better dependency management and versioning.demo/clustering.js (3)
76-78: Enhance color mapping for multiple clustersThe current color mapping handles only a few cluster labels and defaults to yellow for others. This may not provide distinct colors for all clusters, especially when dealing with more clusters.
Consider using a color palette or generating colors dynamically to represent each cluster uniquely:
const colors = ["blue", "red", "green", "orange", "purple", "cyan", "magenta"]; const clusterColor = cluster === -1 ? "black" : colors[cluster % colors.length] || "yellow"; u.addSeries({ label: `${i} (cluster ${cluster})`, - stroke: cluster === -1 ? "black" : cluster === 0 ? "blue" : cluster === 1 ? "red" : "yellow", + stroke: clusterColor, width: 1, }, seriesIdx);
71-82: Ensure series indices are managed correctly inrunClusteringWhen updating the plot with new clustering results, the code deletes and adds series for each data point. This could lead to performance issues or index mismatches if not managed carefully.
Instead of deleting and adding series each time, consider updating the properties of existing series to reflect the new clustering results:
clusterLabels.forEach((cluster, i) => { const seriesIdx = i + 1; - u.delSeries(seriesIdx); - u.addSeries({ + u.series[seriesIdx] = { label: `${i} (cluster ${cluster})`, - stroke: /* color mapping */, + stroke: clusterColor, width: 1, - }, seriesIdx); + }; }); -u.redraw(); +u.setSeries(null, false);
66-99: Handle potential errors in event listenersThe event listeners for input changes assume that the input values are valid numbers. Providing invalid input (e.g., non-numeric values) could cause runtime errors or unexpected behavior.
Add input validation to ensure that the values are valid numbers before running clustering:
document.getElementById("clustering-dtw-window").addEventListener("change", function() { const value = parseFloat(this.value); + if (isNaN(value)) { + console.warn("Invalid DTW window value:", this.value); + return; + } dtwOpts.window = value; runClustering(dtwOpts, dbscanOpts); });Apply similar checks for the other event listeners.
demo/changepoint.js (4)
6-895: Consider loading large data from an external sourceIncluding large datasets like
df.dsanddf.ydirectly in the code can impact maintainability and initial load time. Consider loading the data from an external file or generating it dynamically to improve performance and manageability.For example, you could fetch the data from a JSON file:
const df = { - ds: [...], // existing array - y: [...], // existing array + ds: [], // to be populated from external source + y: [], }; + fetch('data.json') + .then(response => response.json()) + .then(data => { + df.ds = data.ds; + df.y = data.y; + // Proceed with worker initialization or other logic here + });Ensure that you adjust the logic to handle asynchronous data loading.
932-971: Consider handling potential errors from the Web WorkerCurrently, there is no error handling for messages from the Web Worker that might indicate an error. Consider adding an error handler to gracefully handle any issues that might occur during processing.
For example, you can add an
onerrorhandler:worker.onmessage = (e) => { // existing code }; + worker.onerror = (e) => { + console.error('Worker error:', e); + // Display an error message to the user or take other appropriate actions + };
938-938: Optimize data transfer to the Web Worker usingTransferableobjectsSending the large
dfobject viapostMessagecan be inefficient due to serialization overhead. Consider usingTransferableobjects such asFloat64Arrayfordf.dsanddf.yto improve data transfer efficiency.Apply changes to convert
df.dsanddf.yto typed arrays and transfer them:const df = { - ds: [...], // existing array - y: [...], // existing array + ds: new Float64Array([...]), // convert to typed array + y: new Float64Array([...]), }; // In the worker communication - worker.postMessage(df); + worker.postMessage(df, [df.ds.buffer, df.y.buffer]); // transfer the underlying buffersEnsure that you adjust the worker code to handle typed arrays appropriately.
964-966: Prevent potential memory leaks by cleaning up event listenersWhen adding event listeners like
window.addEventListener("resize", ...), it's important to remove them when they are no longer needed to prevent memory leaks.If the
uPlotinstance or the page may be destroyed, consider removing the event listener:const resizeHandler = () => { u.setSize(getSize()); }; window.addEventListener("resize", resizeHandler); + // When appropriate, e.g., before destroying the plot or on component unmount + window.removeEventListener("resize", resizeHandler);

1-4: Verify the existence of imported modules
Let's ensure the required modules are present in the correct location.
✅ Verification successful
Let me verify the exports more thoroughly by checking for default exports and named exports using different patterns.
Import paths are correctly referenced and modules exist with expected exports
The verification shows that:
- Both imported modules exist at the correct paths:
demo/dist/@bsull/augurs/dtw.jsdemo/dist/@bsull/augurs/clustering.js
- The modules export the required symbols:
dtw.jsexportsinitSyncas default and has theDtwclassclustering.jsexportsinitSyncas default and has theDbscanClustererclass
The imports are valid and match the module structure.

1-5: Imports are correctly defined
The required modules and plugins are properly imported.
897-900: Web Worker is correctly initialized
The Web Worker is properly instantiated with the correct module type.
901-930: highlightChangepointsPlugin function is correctly implemented
The plugin function sets up a drawClear hook to highlight changepoints on the plot. The logic for alternating colors and drawing highlighted regions is sound.

Add error handling for initialization
The initialization lacks error handling and might not work in environments that don't support top-level await. Consider wrapping it in an async IIFE with proper error handling:
-await initChangepoint();
+const initialize = async () => {
+ try {
+ await initChangepoint();
+ self.postMessage("ready");

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion
Remove premature ready notification
The ready message is sent before initialization completes, which could lead to race conditions. This line should be removed as the ready notification has been moved to the initialization function in the previous suggestion.
Additionally, consider standardizing message formats for consistency:
-self.postMessage("ready");
+// Remove this line as ready notification is handled in initialization
+
+// Consider using consistent message format:
+// self.postMessage({ type: 'ready' }); // for ready notification
+// self.postMessage({ type: 'result', data: cps }); // for results
+// self.postMessage({ type: 'error', message: error.message }); // for errorsCommittable suggestion skipped: line range outside the PR's diff.

💡 Codebase verification
Based on the analysis of the codebase, I can now provide the final response:
Worker lifecycle needs proper cleanup
The worker is instantiated but never terminated when no longer needed. Add cleanup code in the main thread:
- In
demo/changepoint.js, add a cleanup function to terminate the worker:function cleanup() { worker.terminate(); }
- Call this cleanup when the visualization is destroyed or when switching views
🔗 Analysis chain
Verify worker lifecycle management
Ensure that the main thread properly manages this worker's lifecycle, including termination when no longer needed.
Let me gather more context about the worker usage pattern.
Let me check if there are any cleanup patterns in the codebase.

Move ready message after initialization
The ready message should be sent after successful initialization to prevent race conditions.
Move the ready message inside the initialization block:
-await Promise.all([initDtw(), initClustering()]);
-self.postMessage("ready");
+try {
+ await Promise.all([initDtw(), initClustering()]);
+ self.postMessage("ready");

Add input validation and error handling
The message handler lacks input validation and error handling, which could lead to runtime errors or unclear failure modes.
Consider implementing these safety measures:
self.onmessage = (e) => {
+ try {
const { dtwOpts, dbscanOpts, data } = e.data;
+ if (!Array.isArray(data) || data.length === 0) {
+ throw new Error('Invalid or empty data array');
+ }
+ if (!dtwOpts || !dbscanOpts) {
+ throw new Error('Missing required options');
+ }
const dtw = Dtw.euclidean(dtwOpts);
const distanceMatrix = dtw.distanceMatrix(data);
+ // Send progress update
+ self.postMessage({ progress: 'Distance matrix computed' });
const clusterer = new DbscanClusterer(dbscanOpts);
const labels = clusterer.fit(distanceMatrix);
- self.postMessage(labels);
+ self.postMessage({ result: labels });
+ } catch (error) {
+ self.postMessage({ error: error.message });
+ }
};Additionally, consider implementing memory-efficient processing for large datasets:
- Process the distance matrix in chunks
- Provide progress updates during computation

Add error handling for data fetching in constructor
When fetching the clustering data in the constructor, there is no error handling for the fetch call. If the network request fails, this.data will remain undefined, potentially causing errors later.
Modify the constructor to handle fetch errors gracefully:
this.dataPromise = fetch("./outlier.data.json")
.then((res) => res.json())
+ .then((data) => {
+ this.data = data.data;
+ })
+ .catch((error) => {

Avoid overwriting the worker's onmessage handler in cluster method
Currently, the cluster method assigns a new onmessage handler to this.worker.onmessage each time it's called. If cluster is invoked multiple times before previous invocations have completed, this could lead to race conditions and incorrect message handling, as the handler is overwritten.
To handle multiple concurrent calls without interference, consider using addEventListener to attach message handlers and ensure they are properly cleaned up after use. Here's how you can modify the cluster method:
cluster = async (dtwOpts, dbscanOpts) => {
- return new Promise((resolve, reject) => {
+ return new Promise((resolve) => {
const start = performance.now();
this.worker.postMessage({
dtwOpts,
dbscanOpts,
data: this.data.slice(1).map(arr => new Float64Array(arr)),
});
- this.worker.onmessage = (e) => {
+ const handleMessage = (e) => {
const elapsed = (performance.now() - start);
resolve({ clusterLabels: e.data, elapsed });
+ this.worker.removeEventListener('message', handleMessage);
};
- };
- });
+ this.worker.addEventListener('message', handleMessage);
+ })

Potential issue with onmessage handler in ClusteringWorker.create method
In the create method, the onmessage handler is set directly on worker.worker.onmessage. This could conflict with other onmessage handlers and may not handle errors effectively.
Consider modifying the create method to use addEventListener for the worker messages and to ensure proper cleanup:
static create = () => {
return new Promise((resolve, reject) => {
const worker = new ClusteringWorker();
- worker.worker.onmessage = (e) => {
+ const handleMessage = (e) => {
if (e.data === "ready") {
worker.dataPromise.then(() => resolve(worker));
+ worker.worker.removeEventListener('message', handleMessage);
} else {
reject();
+ worker.worker.removeEventListener('message', handleMessage);
}
}
+ worker.worker.addEventListener('message', handleMessage);
})

Ensure indices are within bounds when accessing ds
When looping over cps.indices.slice(1), accessing ds[cp] assumes that cp is within the bounds of ds. To prevent potential runtime errors, ensure that cp is within the bounds of ds.
Apply this diff to add a bounds check:
for (const cp of cps.indices.slice(1)) {
+ if (cp >= ds.length) continue;
const right = ds[cp];
const rightPos = u.valToPos(right, "x", true);
highlightAt(left, rightPos);
left = rightPos;
color = color === "lightgrey" ? "white" : "lightgrey";
u.ctx.fillStyle = color;
