zkool_graphql is only release from source. As a 100% Rust app, it is easy to build for many architectures and therefore, we don't provide pre-built binaries.

Clone from github

git clone https://github.com/hhanh00/zkool2

Build

Requirement: Install Rust

Then build with cargo.

cd rust
cargo b -r --features=graphql --bin zkool_graphql

This creates the executable zkool_graphql in the target/release directory.

Configuration

The config file needs to specify the path to the database file (which will be automatically created), the URL to the LightwalletD server and the listening port.

db_path = "zkool.db"
lwd_url = "https://zec.rocks"
port = 8000

Alternatively, you can specify another config file or set the values on the command line.

Usage: zkool_graphql [OPTIONS]

Options:
  -c, --config-path <CONFIG_PATH>
  -d, --db-path <DB_PATH>
  -l, --lwd-url <LWD_URL>
  -p, --port <PORT>
  -C, --coin <COIN>                Coin type for a database being created:
                                   0=mainnet, 1=testnet, 2=regtest, 3=ZSA regtest
  -h, --help                       Print help

Using Testnet or Regtest

Pass --coin when the database is created: 1 for testnet, 2 for regtest, 3 for the ZSA regtest. An existing database keeps the network it was created on, whatever the flag says.

Without --coin, the file name decides for a new database: testnet in the name means testnet, regtest means regtest, zsa the ZSA regtest, and anything else mainnet.
