We cut @nodejs memory in half with a one-line Docker image swap.

No code changes. No new APIs. Just smaller heaps.

How do you measure when a component is โ€œreadyโ€? โฑ๏ธ

LCP is too global; Element Timing is too specific.

๐Ÿ› ๏ธ Iโ€™ve been working with Bloomberg on a new #webperf API: Container Timing. Think of it as โ€œLCP for a web componentโ€, providing aggregated paint timing for a subtree.

Really wishing that somebody would hire my company (@igalia.com) to standardize/implement support for import maps in web workers.
