configs for driver

• If the CovenantSQL endpoint comes with HTTPS then .pem and .key files are needed for requests:

const config = {
    endpoint: 'e.morenodes.com:11108', // testnet endpoint with https
    database: `${DB_ID}`, // your DB id created by `cql` tools
    key_dir: path.resolve(`${KEY_FILE_RELATIVE_PATH}`), // your key file
    https_pem_dir: path.resolve(`${PEM_FILE_RELATIVE_PATH}`) // your pem file (cert file)
}

• If only HTTP is needed, then your config could be:

const config = {
    endpoint: 'localhost:11105', // local testnet endpoint without https
    database: `${DB_ID}`, // your DB id created by `cql` tools
    bypassPem: true // bypass https config
}

connect and query

import cql from 'node-covenantsql'

const config = {...} // see above

cql.createConnection(config).then(async (connection: any) => {
    // read
    const data1 = await connection.query("select ? + ?", [2.1, 3.2]);
    console.log(data1);
        
    // write
    const createTableSQL = `
    CREATE TABLE IF NOT EXISTS contacts (\
    contact_id INTEGER PRIMARY KEY,
    first_name TEXT NOT NULL,
    last_name TEXT NOT NULL,
    email text NOT NULL UNIQUE,
    phone text NOT NULL UNIQUE
    );
    `
    const status1 = await connection.exec(createTableSQL)
    console.log(`exec1 status:`, status1);

    const data2 = await connection.query("show tables;");
    console.log(data2);
}).catch((e: any) => console.log(e))
