This repository contains a proposal for a more advanced templating DOM API. The proposal itself is meant to advance an already ongoing discussion on the subject that's happening here.
A semi-formal API specification is in the spec.ts file. A partial polyfill
(designed to demonstrate the concept) is in the polyfill.ts file.
Should this proposal be accepted, and the discussion would move forward, a more formal proposal should be created, along with a feature-full polyfill and a set of tests for verifying potential implementations in browsers.
Demos are available at the following location: https://jurca.github.io/dynamic-template/index.html
Some demos contain additional comments in the source code. Furthermore, there are comments in the polyfill itself elaborating on the intended behavior of a full-featured implementation.
