Is it possible to include external JavaScript libraries in Salesforce components?

Hi Vikas Kumar,

Yes,you can include external javascript libraries in your component and application.To reference a JavaScript library  you’ve to upload as a static resource, use a <ltng:require> tag in your .cmp or .app markup.

<ltng:require scripts=”{!$Resource.***YourresourceName***}”
afterScriptsLoaded=”{!c.afterScriptsLoaded}” />

Thanks
