Idiomorph is a small, dependency-free JavaScript library for morphing one DOM tree into another while preserving element state like focus. It uses id sets to match elements structurally, improving on id-only morphing approaches used by morphdom and nanomorph.

Use cases

• morph dom trees in place without losing focus or state
• update page content incrementally in a hotwire/turbo app
• preserve dom elements during html swaps in htmx
• diff and patch html fragments client-side
• smooth dom transitions when server renders new html

When to choose

• you need dom morphing that matches elements based on child structure, not just ids
• you want a tiny, dependency-free library usable via script tag or ESM
• you use Turbo 8 or htmx and want official-grade morphing support

When to avoid

• you need a full virtual-dom or reactive rendering framework
• your updates are simple full-element replacements where morphing is unnecessary
