The Yorkie JavaScript SDK implements the client-side libraries.

How to use JS SDK

To get started using Yorkie JavaScript SDK, see: https://yorkie.dev/docs/js-sdk

How yorkie-js-sdk works

yorkie-js-sdk uses gRPC-web for communicating with Yorkie Server built on gRPC.

 +--Browser--+           +--Envoy---------+         +--Yorkie-----+
 |           |           |                |         |             |
 | gRPC-web  <- HTTP1.1 -> gRPC-web proxy <- HTTP2 -> gRPC server |
 |           |           |                |         |             |

Building and Testing the SDK

Building yorkie-js-sdk

For building yorkie-js-sdk, You'll first need Node.js installed(Node.js version 16+ and npm version 7.10+ are required).

# install packages
$ npm install

# build
$ npm run build

For generating proto messages and the service client stub classes with protoc and the protoc-gen-grpc-web.

How to install protoc-gen-grpc-web: https://github.com/grpc/grpc-web#code-generator-plugin

# generate proto messages and the service client stub classes
$ npm run build:proto

Primary "source of truth" location of protobuf message is in yorkie. We manage the messages in the repository.

Testing yorkie-js-sdk with Envoy, Yorkie and MongoDB.

Start MongoDB, Yorkie and Envoy proxy in a terminal session.

$ docker-compose -f docker/docker-compose.yml up --build -d

Start the test in another terminal session.

$ npm run test

To get the latest server locally, run the command below then restart containers again:

$ docker pull yorkieteam/yorkie:latest
$ docker-compose -f docker/docker-compose.yml up --build -d

Starting co-editing example with CodeMirror

Start MongoDB, Yorkie and Envoy proxy in a terminal session.

$ docker-compose -f docker/docker-compose.yml up --build -d

Start the webpack-dev-server in another terminal session.

$ npm run dev

Open the co-editing example page served by webpack-dev-server in your browser.

$ open http://0.0.0.0:9000/
