Creating and Enhancing Aura Elements
- Choose File | New | Lightning Part to create an Aura element.
- Within the New Lightning Bundle panel, enter helloWorld for the element title.
- Click on Submit
Your element markup ought to seem like the next:
What’s a Part?
A element is a bundle that features a definition useful resource, written in markup, and will embody extra, optionally available sources like a controller, stylesheet, and so forth.
A useful resource is type of like a file however saved in Salesforce somewhat than on a file system.
There are the opening and shutting <aura:element> tags, with some static HTML in between.
A bundle is type of like a folder. It teams the associated sources right into a single element. Sources in a bundle are auto-wired collectively by way of a naming scheme for every useful resource sort.

What’s an App?
- An app makes use of <aura:utility> tags as an alternative of <aura:element> tags.
- Solely an app has a Preview button within the Developer Console.
What Are Apps For?
- When writing markup, you may add a element to an app, however you can’t add an app to a different app, or an app to a element.
- An app has a standalone URL that you would be able to entry whereas testing, and which you’ll publish to your customers. We frequently refer to those standalone apps as “my.app.”
- You’ll be able to’t add apps to Lightning Expertise or the Salesforce app—you may solely add parts. After the final unit this would possibly sound bizarre; what precisely do you add to the App Launcher, if not an app? What you add to App Launcher is a Salesforce app, which wraps up an Aura element, one thing outlined in a <aura:element>. An Aura parts app—that’s, one thing outlined in a <aura:utility> —can’t be used to create Salesforce apps. A bit bizarre, however there it’s.
Part Attributes
Attributes on parts are like occasion variables in objects. They’re a solution to save values that change, and a solution to title these worth placeholders.
For instance, let’s say we wished to write down a helloMessage element that prints a customized message. We will envision including a message attribute to this element to customise its output.
Instance:
<aura:element> <aura:attribute title="message" sort="String"/> <p>Hey! [ message goes here, soon ]</p> </aura:element>
