App Development

Build a lightning application using Core Lightning APIs.

There are several ways to connect and interact with a Core Lightning node in order to build a lightning app or integrate lightning in your application.

• Using JSON-RPC commands if you're building an application in the same system as the CLN node.
• Using REST APIs if you're building an application in a remote client and want to connect to the CLN node over a secure network using REST interface.
• Using gRPC APIs if you're building an application in a remote client and want to connect to the CLN node over a secure network using gRPC interface.
• Using Commando to connect to a CLN node over the lightning network and issue commands.
• Using WSS Proxy to connect to a CLN node over web secure socket proxy.
• Third-party libraries that offer JSON over HTTPS or GraphQL (deprecated) frameworks to connect to a CLN node remotely.
