The qubic http service

The qubic-http service acts as a bridge to the qubic network.
Some of its features include:

• Checking balances
• Broadcasting transactions
• Tick information
• Block height

Building from source

go build -o "server" "./app/grpc_server"

Running the service

qubic-http requires an instance of qubic-nodes for fetching reliable node addresses.

Configuration

The service can be configured either by CLI parameters or environment variables.
The current configuration will be printed at startup.

Required parameters

QUBIC_API_SIDECAR_SERVER_HTTPS_HOST:          "0.0.0.0:8000"
QUBIC_API_SIDECAR_SERVER_GRPC_HOST:           "0.0.0.0:8001"
QUBIC_API_SIDECAR_SERVER_MAX_TICK_FETCH_URL:  "http://127.0.0.1:8080/max-tick"

QUBIC_API_SIDECAR_POOL_NODE_FETCHER_URL:      "http://127.0.0.1:8080/status"

Optional parameters

QUBIC_API_SIDECAR_SERVER_READ_TIMEOUT:        (default: 5s)
QUBIC_API_SIDECAR_SERVER_WRITE_TIMEOUT:       (default: 5s)
QUBIC_API_SIDECAR_SERVER_SHUTDOWN_TIMEOUT:    (default: 5s)

QUBIC_API_SIDECAR_POOL_NODE_FETCHER_TIMEOUT:  (default: 2s)
QUBIC_API_SIDECAR_POOL_INITIAL_CAP:           (default: 5)
QUBIC_API_SIDECAR_POOL_MAX_IDLE:              (default: 20)
QUBIC_API_SIDECAR_POOL_MAX_CAP:               (default: 30)
QUBIC_API_SIDECAR_POOL_IDLE_TIMEOUT:          (default: 15s)

Docker (recommended)

A docker-compose.yml file is provided in this repository. You can run it as-is using docker compose up -d.
This will start a qubic-nodes service alongside qubic-http.

It may be necessary to configure qubic-nodes with an up-to-date list of peers if the service fails to start.

Standalone

Setting up a qubic-nodes instance is outside the scope of this documentation, but you can learn about it on thequbic-nodes GitHub.
We assume that qubic-nodes is running locally on port 8080.

Export the required environment variables:

export QUBIC_API_SIDECAR_SERVER_HTTPS_HOST="0.0.0.0:8000"
export QUBIC_API_SIDECAR_SERVER_GRPC_HOST="0.0.0.0:8001"
export QUBIC_API_SIDECAR_SERVER_MAX_TICK_FETCH_URL="http://127.0.0.1:8080/max-tick"
export QUBIC_API_SIDECAR_POOL_NODE_FETCHER_URL="http://127.0.0.1:8080/status"

You can now start the service:
