Modules in deno are imported in both Javascript and Typescript using ES6 standard.
We can import and export deno modules using import and export keywords.
Import – Deno Modules
import keyword allows you to include and use modules held elsewhere, on your local file system, or remotely.
In order to import a module in Deno, we need to reference it by URL.
For example:
import { serve } from "https://deno.land/std/http/server.ts";
Export – Deno Modules
export keyword allows you to specify which parts of your module are accessible to users who import your module.
In order to export a module in Deno, we need to append the export keyword.
For example, here we are exporting a function named “add” from the math.ts typescript file.
Filename: math.ts
export function add(a: number, b: number): number {
return a + b;
}
All functions, classes, constants, and variables which need to be accessible inside external modules must be exported.
That’s all about modules in deno.
