Undocumented Hypothes.is Badge API (used by Chrome extension):

```python """ Return the number of public annotations on a given page.

This is for the number that's displayed on the Chrome extension's badge.

Certain pages are blocklisted so that the badge never shows a number on those pages. The Chrome extension is oblivious to this, we just tell it that there are 0 annotations. """ ```

js const rs = new ReadableStream({ start(controller) { controller.enqueue('hello'); } }); const w = new Worker('worker.js'); w.postMessage(rs, [rs]);

js onmessage = async (evt) => { const rs = evt.data; const reader = rs.getReader(); const {value, done} = await reader.read(); console.log(value); // logs 'hello'. };

```svelte

js export async function load({isDataRequest}) { const slowData = getSlowData(); return { nested: { slow: isDataRequest ? slowData : await slowData } }; }

In this example, we race two promises: a 200ms delay and the actual data call we want to make. If the delay resolves first, then the data call is taking longer than 200ms and we should go ahead and render the page with partial data. If the data call resolves first, then we got the data under the time limit and we can render the page with complete data.

```js const TIME_TO_RESOLVE_MS = 200; export async function load() { const slowData = getSlowData();

const result = await Promise.race([delay(TIME_TO_RESOLVE_MS), slowData]);

return { nested: { slow: result ? result : slowData } }; }

async function getSlowData() { // randomly delay either 50ms or 1s // this simulates variable API response times await delay(Math.random() < 0.5 ? 50 : 1000); return '😴'; }

function delay(ms) { return new Promise(res => setTimeout(res, ms)); } ```
