I have a lightning component as below on Opportunity standard lightning page.


        class="slds-icon" />


<aura:component >
  <aura:attribute name="class" type="String"/>
  <aura:attribute name="xlinkHref" type="String"/>
  <aura:attribute name="ariaHidden" type="String" default="true"/>

Also, I have a static resource uploaded with name SLDS212.

For every release, I go to Downloads - Lightning Design Systems, download new file and upload to static resource and update my components.

Is there a better way to do this, instead of downloading the styles sheet for every release and uploading?

Please note that there is no <aura:application> involved here.

Cascading Style Sheets "cascade", meaning that since LEX uses SLDS, you don't need to import the styles a second time. Simply assume that they exist and work correctly. When possible, use standard components with standard documented values; if SLDS changes, those components will take on the new styles as well.

For example, svgComponent has been deprecated, and it is expected that you will use lightning:icon or one of the other variants, such as lightning:buttonIcon if you need an icon button:

<lightning:icon iconName="standard:product" />
  • So what should I pass for xlinkHref attribute in my example?

  • @javanoob In your specific case, use the standard lightning:icon component, such as <lightning:icon iconName="standard:product" />.

    @javanoob Also, as an aside, Salesforce specifically recommends that you do not use svgIcon, but instead use the standard component.
