@ytsaurus/javascript-wrapper v0.10.3

YTsaurus platform javascript wrapper (Browser + Node.js)

The library helps to make requests to YTsaurus platform backend over HTTP API.

Installation

npm install @ytsaurus/javascript-wrapper

Usage

const yt = require('@ytsaurus/javascript-wrapper')();

// The example show how to set global options for all commands.
// But if you need to communicate with several cluster then you have to provide proxy and token for each separate command.
yt.setup.setGlobalOption('proxy', 'plato.yt.my-domain.com');
yt.setup.setGlobalOption('secure', true);

yt.setup.setGlobalOption('authentication', {
  type: 'domain',
});

yt.setup.setGlobalOption('timeout', 15000);

// Example 1
yt.v3.get({path: '//sys/users/yozhik/@'});

yt.v3
  .get({
    setup: {
      proxy: 'hahn.yt.my-domain.com',
      authentication: {
        type: 'none',
      },
    },
    parameters: {path: '//sys/users/yozhik/@'},
  })
  .done(function (userAttributes) {
    // ...
  });

// Example 2
yt.v3.set({path: '//sys/users/yozhik/@banned'}, true);

yt.v3
  .set({
    setup: {
      proxy: 'banach.yt.my-domain.com',
      authentication: {
        type: 'oauth',
        token: 'abcdefghijklmnopqrstuvwxyz',
      },
    },
    parameters: {path: '//sys/users/yozhik/@banned'},
    data: true,
  })
  .done(function () {
    // ...
  });

Configuration

The library allows to set global and local settings for each request.

{
    maxSize: 64 * 1024,
    maxCount: 2,
    encoder(string) {
        return window.btoa(utf8.encode(string));
    }
}

Events

There is ability to subscribe for events: requestStart, requestEnd, error

yt.subsribe('requestStart', function () {
    console.log('requestStart');
});

It might be useful if you need to show the presence of active requests or if you need to log some error.

Commands

Available commands might be found at https://ytsaurus.tech/docs/en/api/commands, but all the commands should be written in camelCase:

If you don't need to override local configuration options you can use syntax:

// yt.<version>.<command>(<parameters>[, <data>])
yt.v3.get({path: '//home/user/@account'});
yt.v3.set({path: '//home/user/@account'}, 'default');

also there is ability to define options by setup field:

/**
 * yt.<version>.<command>({
 *    parameters: <parameters>,
 *    data: <data>,
 *    setup: <setup>
 * })
 */
const setup = {timeout: 3000};
yt.v3.get({setup, parameters: {path: '//home/user/@account'}});
yt.v3.set({setup, parameters: {path: '//home/user/@account'}}, 'default');
