The @as decorator is commonly used on record types to alias record field names to a different JavaScript attribute name.

This is useful to map to JavaScript attribute names that cannot be expressed in ReScript (such as keywords).

Example

<CodeTab labels={["ReScript", "JS Output"]}>

type action = {
  @as("type") type_: string
}

let action = {type_: "ADD_USER"}

var action = {
  type: "ADD_USER"
};
