Use Node's package.json imports field for small private aliases like #db, #http/*, and #config without relying on a bundler alias....

The Cookie Store API is the cleaner way to work with script-visible browser cookies. It gives you promise-based reads, object-shaped writes, deletes, and change events instead of forcing you to parse and assign `document.cookie` strings. ...

JavaScript now has native `Uint8Array` helpers for converting bytes to and from Base64 and hex. Use them when your data is actually bytes: file chunks, image payloads, cryptographic output, compact URL tokens, or binary API responses. They are cleaner than `atob()` and `btoa()` because they work with `Uint8Array` directly....

HTML-in-Canvas is big news because it targets one of the worst tradeoffs in web development: canvas gives you powerful rendering, but once you draw your UI there, you lose a lot of normal browser behavior. Chrome's experimental origin trial points toward a better model where a canvas app can draw real HTML while keeping browser-managed text, controls, focus, accessibility, and interaction....

In Vite, a variable that starts with `VITE_` is public browser configuration, not a secret. Vite exposes it through `import.meta.env` and bundles it into client-side code at build time, so use `VITE_` for values like API base URLs, keep real secrets on the server, and only use `loadEnv()` when `.env` values need to shape `vite.config.*`....

Use the Web Locks API when the same web app can be open in multiple tabs and only one tab or worker should run a browser-side job at a time. It is a clean fit for sync jobs, cache refreshes, IndexedDB maintenance, and polling loops that should not stampede just because the user opened your app twice....
