## Install

```bash

npm i egg-zookeeper --save

```

## Usage

1. Install & enable the plugin in egg

```js

// config/plugin.js

exports.zookeeper = {

  enable: true,

  package: 'egg-zookeeper',	

};

```

2. Create zk client with `app.zk.createClient(connectionString)` api

```js

const client = app.zk.createClient('localhost:2181');

yield client.ready();

const path = '/test-path';

function listChildren(client, path) {

  client.getChildren(

    path,

    event => {

      console.log('Got watcher event: %s', event);

      listChildren(client, path);

    },

    (err, children, stat) => {

      if (err) {

        console.log('Failed to list children of %s due to: %s.', path, err);

        return;

      }

      console.log('Children of %s are: %j.', path, children);

    }

  );

}

// create a new path

client.create(path, err => {

  if (err) {

    console.log('Failed to create node: %s due to: %s.', path, err);

  } else {

    console.log('Node: %s is successfully created.', path);

  }

  // list and watch the children of given node

  listChildren();

});

```
