Difference Between Clint Side Controller And Server Side Controller Lightning Components

DIFFERENCE BETWEEN CLINT SIDE CONTROLLER AND SERVER SIDE CONTROLLER LIGHTNING COMPONENTS


Server Side Components :

JS Controller :

doInit: function(component, event, helper) {  
     var page = component.get("v.page") || 1;  
      var recordToDisply = component.find("recordSize").get("v.value");  
      helper.getAccounts(component, page, recordToDisply, component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    },  
    previousPage: function(component, event, helper) {  
      var recordToDisply = component.find("recordSize").get("v.value");  
      component.set("v.page", component.get("v.page") - 1);  
     helper.getAccounts(component, component.get("v.page"), recordToDisply,component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    },  
    gotoFirstPage : function(component, event, helper) {  
     component.set("v.page",1);  
      var recordToDisply = component.find("recordSize").get("v.value");  
      helper.getAccounts(component, 1, recordToDisply,component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    },  
   gotoLastPage : function(component, event, helper) {  
      component.set("v.page",component.get("v.pages"));  
      var recordToDisply = component.find("recordSize").get("v.value");  
      helper.getAccounts(component, component.get("v.pages"), recordToDisply,component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    },  
    nextPage: function(component, event, helper) {  
      var recordToDisply = component.find("recordSize").get("v.value");  
      component.set("v.page", component.get("v.page") + 1);  
      helper.getAccounts(component, component.get("v.page"), recordToDisply,component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    },  
   onSelectChange: function(component, event, helper) {  
     var page = 1  
      var recordToDisply = component.find("recordSize").get("v.value");  
      helper.getAccounts(component, page, recordToDisply,component.get('v.selectedTabsoft'), component.get("v.isAsc"));  
    }


Here We Can observe that each time on button click we are calling server side controller method .
So, we are querying the records but, according to  salesforce governer limits we can use only 100 SOQL queries.If we exceed that limit we will get ERROR : System.LimitException.


Clint Side Component:

JS Controller :


({
    
    doInit:function(component,event,helper){
        helper.getContacts(component);
    },
    next:function(component,event,helper){
        helper.next(component);
    },
    previous:function(component,event,helper){
        helper.previous(component);
    },
  
    First:function(component,event,helper){
        helper.First(component);
    },
    Last:function(component,event,helper){
        helper.Last(component);
    },

})


Here we no need to call server side controller method each time on the button click.

cons :

If the number of pages are increased ,  loading of record become slow.

How To Make DataTable Column Resizable

Image
First, we will use the dummy table shared by the  Lightning Design System . We need to store the original width of the selected column to calculate the new width for which we have defined the oldWidth attribute to store the value. We also need the distance of the selected column width from the left of the screen to identify the start point from where user start to drag the column. We have used mouseStart attribute for the same. We have used two mouse events to identify when user start to drag and when user is dragging the column for adjusting the width. onmousedown  will be fired when user click on the column divider element and ondrag  will be fired when user is dragging th .
