Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Before You Begin

To work with Lightning apps and components, create a Developer Edition org.

For this quick start tutorial, you don’t need to create a Developer Edition organization or register a namespace prefix. But you want to do so if you’re planning to offer managed packages. You can create Aura components using the UI in Enterprise, Performance, Unlimited, Developer Editions, or a sandbox.

Note

You need an org to do this quick start tutorial, and we recommend that you don’t use your production org. You only need to create a Developer Edition org if you don’t already have one.

  1. In your browser, go to https://developer.salesforce.com/signup?d=70130000000td6N.
  2. Fill in the fields about you and your company.
  3. In the Email field, make sure to use a public address you can easily check from a Web browser.
  4. Type a unique Username. Note that this field is also in the form of an email address, but it does not have to be the same as your email address, and in fact, it’s usually better if they aren’t the same. Your username is your login and your identity on developer.salesforce.com, so you’re often better served by choosing a username such as firstname@lastname.com.
  5. Read and then select the checkbox for the Main Services Agreement and then click Submit Registration.
  6. In a moment you’ll receive an email with a login link. Click the link and change your password.
