Script Downloader
This node is deprecated and kept only so existing projects keep working. It is not offered in the node picker for new use.
Deprecated loader for external script URLs. Use project modules or a Function node injecting a script tag.
The legacy Script Downloader fetches the JavaScript files listed on its numbered inputs and fires loaded when they are available. Deprecated and hidden from the picker.
When to use it
Do not use in new graphs — prefer bundled project modules; where a runtime script tag is unavoidable, inject it from a Function node and gate downstream work on its load event.

Dynamic ports
This node's port list changes at runtime (numbered-inputs); the tables above may be incomplete for a given instance.
Accepts an unbounded numbered series of inputs (see numberedInputs); ports are named "<base> <N>" counting from 0.
Ports at runtime
Script-URL inputs are generated from the configured count (numbered-inputs mechanism).

Code export
Does not export to React yet. A project that uses it exports with this node named in the export report.
Why: deliberately out of scope — the type is deprecated in the catalog, so nobody building today is offered one. A project that still holds one exports it as a named deferral, which is the right answer for a node its own editor has retired.
How export works shows what an export writes, with a worked example.
This page is generated from node-catalog-enriched.json, the node's spec in packages/nodegx-node-spec and the export ledger. Do not edit it by hand — run npm run docs:nodes to regenerate, and fix the source instead.
