Check out v4 of the Fauna CLI

v4 of the Fauna CLI is now in beta.

The new version introduces enhancements to the developer experience, including an improved authentication workflow. To get started, check out the CLI v4 quick start.

Conditional operations

FQL doesn’t have a ternary (conditional) operator. You can get the same result using an if … else statement. For example, to perform an upsert:

// Customer email to look up
let email = "alice.appleseed@example.com"

// Customer data to upsert
let data = {
  name: "Alice Appleseed",
  email: "alice.appleseed@example.com",
  address: {
    street: "87856 Mendota Court",
    city: "Washington",
    state: "DC",
    postalCode: "20220",
    country: "US"
  }
}

// Try to find the existing customer by email.
// If the customer doesn't exist, returns `null`.
let customer = Customer.byEmail(email).first()

// Create or update the customer
// based on existence.
if (customer == null) {
  Customer.create(data)
} else {
  customer!.update(data)
}
