Plugin can be used to write common set of generic codes which can be provided to anyone using a package. Using plugin you can inject apis or insert middleware.

SqlWeb is an example of plugin which add $sql api.

How to create a plugin

export const AwesomePlugin{

    // setup is called by jsstore, so all initialization should happen here
    setup: function(connection, params){

        connection.myApi = {
            insertIntoMyTable: function (data){
                connetion.insert({
                    into:"my_table",
                    values:[data]
                })
            }
        }

    }
}

In the above code we have created a plugin which add api myApi to insert data into specific table.

Now we need to add this plugin to jsstore connection.

var connection = new JsStore.Connection();
connection.addPlugin(AwesomePlugin);

now plugin is installed and can be used. Let's use the api added by plugin

connection.insertIntoMyTable({
    name:'ujjwal gupta'
})
