gedcomkit (npm / WASM)

WASM bindings for gedcomkit, an archival-grade GEDCOM library written in Rust: byte-preserving round-trip, encoding detection and reporting, GEDCOM 5.5 through 7.x. The same source builds target-specific packages for Node, bundlers, or direct browser modules.

import { Gedcom } from "gedcomkit";

const doc = Gedcom.parse(bytes);          // Uint8Array in
console.log(doc.encoding);                 // "Read as ANSEL, declared ANSEL"
for (const person of doc.individuals()) {
  console.log(person.names, person.events);
}
console.log(doc.parentsOf("@I3@"));       // both directions of the link
doc.setLogicalValue("@I1@", [0], "Ada /Lovelace/");
const out = doc.toBytes();                 // untouched lines byte for byte

Build with wasm-pack:

wasm-pack build --target nodejs  --release   # Node
wasm-pack build --target bundler --release   # webpack/vite
wasm-pack build --target web     --release   # plain <script type=module>

Publishing note: wasm-pack names the package after this crate (gedcomkit-wasm); the release workflow renames it to the npm package gedcomkit:

cd pkg && npm pkg set name=gedcomkit && npm publish

The Rust core lives at the root of the same repository; this crate is a thin wasm-bindgen layer over its public API, mirroring the Python binding's shape.
