Quick Start

Let’s start using Yorkie with the JS SDK and a Server. You need an environment that can run JavaScript, such as a browser.

Installation

Install Yorkie JS SDK using npm:

$ npm install yorkie-js-sdk

or just include the following code in the <head> tag of your HTML:

<!-- include yorkie js -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/yorkie-js-sdk/0.2.9/yorkie-js-sdk.js"></script>

If you want to test Yorkie quickly, You can start Envoy and Yorkie with docker-compose. To start them, download manifest files from the docker folder, and then type docker-compose up --build -d in the folder. For more details, please refer to Server for Web.

How to use Yorkie

1. Activating a Client

First, create a Client with RPCAddr and activate it.

const client = new yorkie.Client('localhost:8080');
await client.activate();

2. Attaching a Document

Then, create a Document with a key of Document and attach it to the Client.

const doc = new yorkie.Document('doc-1');
await client.attach(doc);

This automatically synchronizes all changes to the Document attached to the Client with the remote peers.

3. Updating the Document

Now let’s make a change on the Document:

doc.update((root) => {
  root['key'] = 'value'; // {"key":"value"}
});

The changes are immediately applied locally and propagated to other peers who subscribe to the Document.

Next, let’s take a look at the JS SDK.
