So I am trying to build a dynamic Navigation bar that I am passing a certain Knowledge URL in to go to our external knowledge base. I have the Property Value on the component which I will be able to put in the URL, but the problem I have is how can I get the value to populate correctly in the Lightning Formated URL?

<lightning-formatted-url value="{knowledgeURL}" label="Knowldege"></lightning-formatted-url>

in the .js file, I do have @api and in the meta.js file, I have a target set.

@api knowledgeURL ;
<property name="knowledgeURL" type="String" default=""></property>
  • What you are showing now is fine I think, what is the problem you are facing? Aug 28 '19 at 16:23

value="{knowledgeURL}" is not correct syntax for LWC. It should be value={knowledgeURL} without ". Install the salesforce LWC extensions so that you get to know these minor errors while saving itself.

<lightning-formatted-url value={knowledgeURL} label="Knowldege"></lightning-formatted-url>

You should install Salesforce extension pack (recommended)


If you check the documentation,

Displays a URL with a protocol such as http:// and https://. Protocol http:// is automatically prepended to a value like "my/path" to create an absolute URL. A value "/my/path" creates a relative URL.

So, you can set url without https://

Sample code:


        <lightning-formatted-url value={knowledgeURL} label={knowledgeLabel}></lightning-formatted-url>


@api knowledgeURL;
@api knowledgeLabel;

    I think @track should be @api according to the users use case

    @Gunner1714 added in answer - its syntax mistake. You should be using LWC extension Aug 28 '19 at 16:29

    Also, the extension is included in the extension pack and should not be downloaded directly.
