Before You Begin

To work with Lightning apps and components , follow these prerequisites.
  1. Create a Developer Edition organization
  2. Define a My Domain Name

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 Lightning components using the UI in Enterprise, Performance, Unlimited, Developer Editions, or a sandbox. If you don’t plan to use a Developer Edition organization, you can go directly to Define a My Domain Name.

Note

Create a Developer Edition Organization

You need an org to do this quick start tutorial, and we recommend 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 Master Subscription 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.

Define a My Domain Name

A My Domain name helps you enhance access security and better manage login and authentication for your organization. If your My Domain name is universalcontainers, then your login URL is https://universalcontainers.my.salesforce.com and your Lightning URL is https://universalcontainers.lightning.force.com. For more information, see My Domain in the Salesforce Help.
