Importing & Exporting

Aura provides a simple and efficient way to share and use code across files through its core module system.

Exporting​

By default, everything in an Aura file is private to that file. To make a variable, function, or class available to other files, use the export keyword.

// constants.aura
export const PI = 3.14159;
export let version = "1.0.0";

// utils.aura
export function sayHello(name: string) {
    print `Hello, ${name}!`;
}

export class Calculator {
    public function add(a: i32, b: i32): i32 {
        return a + b;
    }
}

Importing​

To use an exported member from another file, use the import statement.

Named Imports​

You can import specific members from a file using the {} syntax.

// main.aura
import { sayHello, Calculator } from "./utils";
import { PI } from "./constants";

sayHello("Aura");
let calc = new Calculator();
print calc.add(10, 20);

Module Imports (Star Imports)​

You can import all exported members from a file under a namespace using the * as namespace syntax.

// main.aura
import * as utils from "./utils";
import * as constants from "./constants";

utils.sayHello("Aura");
print constants.PI;

Best Practices​

  • Prefer named imports for better static analysis and modularity.
  • Organize related exports into focused files (e.g., constants.aura, types.aura).
  • Keep your module exports concise and avoid unnecessary public exposure.
