Usage

example of usage:

import MindsDB from 'mindsdb-js-sdk';

//connection
MindsDB.connect("http://127.0.0.1:47334/api", [{key:"apikey",value:"placeholder"}]);
const connected = await MindsDB.ping();
if (!connected) return;

// lists of predictors and datasources
const predictorsList = MindsDB.dataSources();
const predictors = MindsDB.predictors();

// get datasource
const catsDatasorce = await MindsDB.DataSource({name: 'cat'}).load();

// get predictor
const catAgePredictor = await MindsDB.Predictor({name: 'catAge'}).load();

// query
const result = catAgePredictor.queryPredict({color: 'white', weight: '100'});
console.log(result.age);

MindsDB.disconnect();
