DataMorph WASM bindings

This folder contains a small wasm-bindgen adapter crate that exposes a JSON-only API for using DataMorph (data-morph) from JS/TS.

Exports

All exports return JSON strings of the form:

{ "ok": true, "value": "...", "context": { "payloadFormat": "json", "payload": {}, "attributes": {}, "variables": {}, "error": null } }

• evaluate_script(script: string, contextJson: string) -> string
• validate_script(script: string) -> string
• definitions_with_scope_d(contextJson: string) -> string (requires metadata+internals enabled on the Rust side)
• fn_metadata_json(includeStandardPackages: boolean) -> string

Context JSON schema

contextJson must be valid JSON (keys must be quoted):

{
  "payloadFormat": "json",
  "payload": { "any": "json" },
  "attributes": { "k": "v" },
  "variables": { "k": 123 },
  "error": null
}

Notes:

• Unknown top-level keys are accepted and become additional scope variables.
• attributes and variables must be JSON objects.
• variables also accepts the alias key vars.
• Header-driven input/output directives can read/write non-JSON formats; support is best-effort and may not cover all DataMorph edge-cases.

Build (wasm-pack)

1. Install target + wasm-pack:

rustup target add wasm32-unknown-unknown
cargo install wasm-pack

2. Build npm/bundler-friendly output-dev:

• DEV

cd d:\Code\IntegrationBuilder\IntegrationBuilder\data-morph\wasm
wasm-pack build --target bundler --out-dir .\pkg-web --dev
wasm-pack build --release --target web --out-dir pkg-web -- --features production

• PROD

Set-Location "d:\Code\IntegrationBuilder\IntegrationBuilder\data-morph\wasm"

wasm-pack build --release --target bundler --out-dir pkg-web -- --features production

or

wasm-pack build --release --target web --out-dir pkg-web -- --features production

The generated JS glue + .wasm will be in wasm/pkg/.

Quick smoke test (Node)

After building, you can do a minimal import test from any TS/JS project by importing the generated package. See ts/wasm-loader.ts for a minimal loader.
