How can I access the html text in static resource file in lightning client-side controller?

I know how to upload .html file to static resources and how to acquire it using <ltng:require>, but I do not know how to access its content once it is acquired.


<ltng:require> is used for loading JavaScript and style sheets, not static HTML. In order to make HTML content available for your Lightning JavaScript controller, you'd need to structure your static resource as a JavaScript file that assigns HTML content to some top-level property, which you can then access in your controller and include in your component.

Alternately, you'd need to call out to your server-side Apex controller to query for the body of the StaticResource and return the data to you.

Here's an example of the former approach.

Static Resource testsr

window.myHTML = '<strong>Hello, <em>world!</em></strong>';


<aura:application >
    <aura:attribute type="String" name="html" />
    <ltng:require scripts="{! $Resource.testsr }" afterScriptsLoaded="{!c.afterScriptsLoaded}" />
        <aura:unescapedHtml value="{! v.html }" />


    afterScriptsLoaded : function(component, event, helper) {
        component.set('v.html', window.myHTML);


.THIS strong {
    font-weight: bold;

.THIS em {
    font-style: italic;


enter image description here

  • Oh. It is a pity that it is impossible to have an .html file in static resources. So, .html templates are impossible in lightning. Sep 9 '18 at 16:41
  • Well, that's overstating it a little. There are (at least) two routes to access static HTML, as above. But remember also that a Lightning component is itself something like a template. Your Lightning component markup is HTML + Lightning components.
