Connection

After installing the Ultipa Node.js SDK and setting up a running Ultipa instance, you should be able to connect your application to the Ultipa graph database.

ConnectionPool

Connection to Ultipa can be established by using ConnectionPool, which specifies the information of the connection pool needed.

Below are all the configuration items available for ConnectionPool:

Connect to a Cluster

Example of connecting to a cluster and using graphset 'default'.

import { ConnectionPool } from "@ultipa-graph/ultipa-node-sdk";
import fs from "fs";

let sdkUsage = async () => {

  let hosts = [
    "192.168.1.85:60061", 
    "192.168.1.86:60061", 
    "192.168.1.87:60061"
  ];
  let username = "***";
  let password = "***";
  let crt: Buffer;
  { // Crt is used
    let crt_file_path = "./ultipa.crt";
    crt = fs.readFileSync(crt_file_path);
  }
  let connPool = new ConnectionPool(hosts, username, password, crt);
  
  let conn = await connPool.getActive();
  let isSuccess = await conn.test();
  console.log(isSuccess);
};

sdkUsage().then(console.log).catch(console.log);

Connect to Ultipa Cloud

Example of connecting to an instance on Ultipa Cloud and using graphset 'default'.

import { ConnectionPool } from "@ultipa-graph/ultipa-node-sdk";

let sdkUsage = async () => {

  let hosts = ["3xbotdjas.us-east-1.cloud.ultipa.com:60010"];
  let username = "***";
  let password = "***";
  let otherParams = {
    isHttps: true,
    isHttp: false
  };
  let connPool = new ConnectionPool(hosts, username, password, undefined, undefined, otherParams);
  
  let conn = await connPool.getActive();
  let isSuccess = await conn.test();
  console.log(isSuccess);
};

sdkUsage().then(console.log).catch(console.log);
