Engines

node >=6.0.0 for es6 support

Usage

install

npm install ots.js

init

const OTS = require('ots.js');

let ots = new OTS({
    endPoint: process.env.otsEndPoint,
    accessId: process.env.otsAccessId,
    accessKey: process.env.otsAccessKey,
    instanceName: process.env.otsInstanceName,
    // optional options
    {
        // default 10，connection poolSize
        // use http.Agent, set keepAlie: true
        poolSize: 20
    }
});

// callback style
ots.CreateTable(...args, callback);
// without the callback parameter, it will return a promise object
ots.CreateTable(...args)
  .then(...);
