    password: 'password',
  },

Answer 1

您应该指定托管 clickhouse 的主机和端口

const { ClickHouse } = require('clickhouse');
const clickhouse = new ClickHouse(url: process.env.DATABASE_HOST,
    port: parseInt(process.env.DATABASE_PORT),
    debug: false,
    basicAuth: {
        username: "username",
        password: "password"
    },
    isUseGzip: false,
    config: {
        session_timeout: 60,
        output_format_json_quote_64bit_integers: 0,
        enable_http_compression: 0
    });
clickhouse.query('SHOW DATABASES;').exec((err, rows) => {
console.log(err);
console.log(rows);
})
