catapult-rest

Build Status Coverage Status

Catapult REST gateway combines HTTP and WebSockets to perform read and write actions on the blockchain.

Requirements

Versioning

Make sure you choose a version compatible with the catapult-server node you want to use it with.

Version number is described as follows:

v1.X.Y.Z

  • The first numer is symbolic for pre-release and should not be taken into consideration.
  • X: This serves to lock for compatibility with catapult-server, thus it is safe to update by keeping this number without REST losing server compatibility. Additionally, any breaking change to the server should require to upgrade this number.
  • Y: This serves to lock on safe updates to this project, thus it is safe to update by keeping this number without worrying about introducing breaking changes.
  • Z: Represents minor changes progress, used to identify specific versions when reporting bugs, or to get extensions to the code.

Installation

  1. Edit rest/resources/rest.json configuration:
Parameter Description Example
db.url MongoDB connection URL. mongodb://localhost:27017/
apiNode.host API node connection host. 127.0.0.1
apiNode.port API node connection port. 7900
apiNode.tlsClientCertificatePath API node TLS client certificate path. /api-node-config/cert/node.crt.pem
apiNode.tlsClientKeyPath API node TLS client key certificate path. /api-node-config/cert/node.key.pem
apiNode.tlsCaCertificatePath API node TLS CA certificate path. /api-node-config/cert/ca.cert.pem
websocket.mq.host ZeroMQ connection host. 127.0.0.1
websocket.mq.port ZeroMQ connection port. 7902

Note: catapult-rest has to reach the API node, ZeroMQ and MongoDB ports. If you are running catapult-server on a VPS, you can bind the ports to your local development environment creating an SSH tunnel: ssh -L 27017:localhost:27017 -L 7900:localhost:7900 -L 7902:localhost:7902 -p 2357 <USER>@<VPS_IP>

  1. Install the project's dependencies:
./yarn_setup.sh
  1. Run catapult-rest:
cd rest
yarn build
yarn start resources/rest.json

Usage

Please refer to the documentation for more information.
