Example

Get up and running fast:

import Client from "happypandax-client";

const c = new Client({ name: "my-client" });
c.connect({ host: "localhost", port: 7007 }).then(function (msg) {
  c.handshake({ user: null, password: null })
    .then(function (success) {
      if (success) {
        c.send([{ fname: "get_version" }]).then(function (data) {
          console.log(data);
        });
      } else {
        console.error("Handshake failed")
      }
    })
    .finally(() => c.close());
});

or, using Async/Await syntax:

import Client from "happypandax-client";

let c = new Client({ name: "my-client" });

async function main() {
  const msg = await c.connect({ host: "localhost", port: 7007 });
  const success = await c.handshake({ user: null, password: null });

  if (success) {
    let data = await c.send([{ fname: "get_version" }]);
    console.log(data);
  } else {
    console.error("Handshake failed");
  }

  c.close();
}

main();

Logging

import { log } from "happypandax-client";

// Enable/disable logging
log.enabled = false;

// Custom logger
log.logger = {
  debug: console.debug,
  info: console.info,
  warning: console.warn,
  error: console.error,
};

Behaviour

Due to a change in NodeJS v17, localhost might now return a IPV6 address, however the client will always prefer the IPv4 address. To restore to NodeJS behaviour, set Client.resolve_IPV4_localhost = false;
