Is There an API to Retrieve Available Node Types in Self-Hosted n8n with React?

Below is some guidance based on the n8n documentation:

Is There an API to Retrieve Node Types?

Currently, n8n does not expose a dedicated public API endpoint that returns the list of available node types (or integrations). The available node types (both built-in and community nodes) are documented in the n8n documentation, and the information is embedded in the source rather than exposed via an API.

Options to Consider

1. Reference the Documentation:
   The built-in nodes (integrations) and their details are comprehensively documented. You can point users to the Built-in nodes documentation which includes details about core nodes, cluster nodes, and how credentials interact with those nodes.

2. Custom Approach:
   Since there isn’t an out-of-the-box API, if you require a dynamic list of nodes to show in your React app, you could consider a custom solution such as:

   • Code Parsing: Write a script that parses the n8n source code or the markdown documentation files to extract the node types and then expose them via your own API.
   • Static Data: Maintain a JSON file or another data source which holds the list of available node types (and update it when new nodes are introduced).

3. Community Suggestions:
   If a dynamic API for node types is critical, consider sharing or requesting this feature through the n8n community channels or directly via their issue tracker on GitHub. The n8n team and community are active, and they may consider contributions or suggestions for such functionality.

Summary

There is no built-in API available in self-hosted n8n that lists available node types. The recommended approach is to rely on the public documentation for node types or build your own mechanism to generate this list for your React application.
