Usage

Initialize webserver

1. Add JA_AddWebsocketEndpoint or JA_AddWebsocketEndpoint_WithOnCloseMicroflow to your afterstartup flow

2. Create a websocketidentifier, this will also be the path to the websocketserver

I recommend storing this inside a constant with client exposure for reuse in notify action and the websocket client widget

3. Optionally fill in the max idle time for users to this session

If you initialize the websocket with the JA_AddWebsocketEndpoint_WithOnCloseMicroflow action you will need to configure the following as well:

4. Select the onCloseMicroflow, the microflow can contain one string parameter

5. Fill in the name of the string parameter inside onCloseMicroflowParameterKey

Setup client connection

General tab

1. Place the EZ Websocket client widget inside a context entity

2. Configure the object Id

Note that the object database id is not available here, you will have to provide your own unique object id

3. Fill the websocket identifier with the same identifier from the websocket initialization

4. Configure one or more trigger/action combination(s)

Message handling tab

Message attribute: Configure attribute to receive messages sent directly from the notify action on

Websocket close behaviour tab

Timeout action: If you configured a sessiontimeout during the initialization you can configure the action to perform on sessiontimeout here

Navigate action: Executes action when the websocket component unrenders, examples of this are:

• User navigates away from the page

• User closes the page

• The component becomes invisible

This does not get fired if the user closes the tab or the browser, use the onCloseMicroflow functionality instead

On close MF parameter: Only use this if the websocket is initialized using the JA_AddWebsocketEndpoint_WithOnCloseMicroflow action

• This is the string parameter that will be passed to the on close microflow

Notify all subscribers

1. Add JA_Notify action to your microflow

2. Configure the object Id of which you want to notify the subscribers of

3. Fill the websocket identifier with the same identifier from the websocket initialization

4. Configure the action trigger configured in the client widget

or

5. Add a message you want to send to the clients

Note that the message attribute gets set before the action is executed so that the message is directly available inside the action
