This exposes the Sync Config rewriter as a package usable from JavaScript.

Instantiation

This package requires you to load a compiled WebAssembly file, which depends on your target platform.

On Node.JS, resolve and load the WASM file:

import { readFileSync } from "node:fs";
import { fileURLToPath } from "node:url";

import { instantiate } from "@powersync-community/sync-config-rewriter";

const wasmBuffer = readFileSync(
  fileURLToPath(
    import.meta
      .resolve("@powersync-community/sync-config-rewriter/compiled.wasm"),
  ),
);

const module = await instantiate(wasmBuffer);

For web apps bundled with vite, use explicit URL imports:

import { instantiate } from "@powersync-community/sync-config-rewriter";
import wasmUrl from "@powersync-community/sync-config-rewriter/compiled.wasm?url";

const module = await instantiate(fetch(wasmUrl));

Development

To release a version of this package, update the version entry in package.json, merge to main and manually trigger the publish_npm workflow.
