Expressions for Aura Sites

You can access property values and other information to pass into a component's attributes with expressions.

An expression is any set of literal values, variables, subexpressions, or operators that can be resolved to a single value. Method calls aren’t allowed in expressions.

The expression syntax is {!expression}, where expression is a placeholder for the expression.

These expressions display the authenticated user’s information, images associated with data categories, or record information on a site page.
