# Network: Device Network Information

These functions provide current EdgerOS device network working information.

# Functions

# edger.network()

• Returns: {Promise} Promise object.

Get the network connection information of the currently connected EdgerOS device.

# Example

edger.network().then(data => {
  const { connected, connectionType } = data;
  console.log(connected, connectionType);
}).catch(error => {
  console.error(error);
});

# async / await

async function network() {
  try {
    return await edger.network();
  } catch (error) {
    console.error(error);
  }
}

The obtained data object contains the following members:

• connected {Boolean}.
• connectionType {String}.

App running in the EdgerOS mobile App and running in a normal browser, connected and connectionType have different meanings.

• In the EdgerOS mobile App environment:

  connected indicates the network connection status of the mobile phone at this time, the network connection is normal to true, otherwise it is false.

  connectionType indicates the current network connection type of the mobile phone, which may be: 'wifi', 'cellular', 'none', 'unknown'.

• In browser environment:

  connected indicates whether the WAN interface of the connected EdgerOS device is connected to the Internet.

  connectionType is fixed to 'wifi'.

# Events

The unified event listener provided by Web-SDK:

const listener = (payload) => {
  // Event handling...
}

// add listener
edger.addEventListener('some-event', listener);

// or 
// onAction() is an alias of addEventListener().
edger.onAction('some-event', listener);

// remove listener
edger.removeEventListener('some-event', listener);

// remove all listeners
edger.removeAllListeners();

# network

This event will be received when the network connection status changes.

# Example

const listener = (payload) => {
  const { connected, connectionType } = payload;
  console.log(connected, connectionType);
}

edger.addEventListener('network', listener);
