You can add signal-driven partial re-rendering to an existing page from a CDN file, without taking on a build step or rewriting the markup as components.

Places.js enhances HTML you already have with web components that fill themselves from an API endpoint, plus signal-backed stores that re-render only what changed and can be read from other frameworks. Install it from jsDelivr or with npx jsr add; there is no bundler step. The repository carries 261 commits and 47 tags, with a reference guide at createthirdplaces.org, and contributions must be written by people rather than models. It is pre-1.0 at v0.1.2 with 2 stars, 23 open issues, no licence type named, and benchmark figures it ran itself.
