@caseware/nx-node-tree-shake

Nx graph plugin that wraps JS/TS dependency extraction and narrows static edges using conservative tree-shaking semantics.

Configure In nx.json

{
	"plugins": [
		{
			"plugin": "@caseware/nx-node-tree-shake",
			"options": {
				"mode": "semantic",
				"respectSideEffects": true,
				"removeTypeOnlyEdges": true,
				"bundlerAdapters": ["esbuild", "swc", "babel", "webpack", "rollup", "vite"],
				"fallbackToStaticGraph": true,
				"passthrough": false,
				"debug": false
			}
		}
	]
}

Detailed option schema is available in packages/src/options.json.

Key Exports

• createDependencies
• createNodesV2
• narrowDependencies
• resolveBaseCreateDependencies

Safety Model

• Only removes static edges when imports are provably unused and target declares "sideEffects": false.
• Keeps namespace imports, side-effect imports, dynamic imports, and re-exports.

Local Validation

• yarn nx test @caseware/nx-node-tree-shake --skip-nx-cache
• yarn nx build @caseware/nx-node-tree-shake --skip-nx-cache
