interface ImportMeta

A string representation of the fully qualified module URL. When the module is loaded locally, the value will be a file URL (e.g. file:///path/module.ts).

You can also parse the string as a URL to determine more information about how the current module was loaded. For example to determine if a module was local or not:

const url = new URL(import.meta.url);
if (url.protocol === "file:") {
  console.log("this module was loaded locally");
}

The absolute path of the current module.

This property is only provided for local modules (ie. using file:// URLs).

Example:

// Unix
console.log(import.meta.filename); // /home/alice/my_module.ts

// Windows
console.log(import.meta.filename); // C:\alice\my_module.ts

The absolute path of the directory containing the current module.

This property is only provided for local modules (ie. using file:// URLs).

• Example:

// Unix
console.log(import.meta.dirname); // /home/alice

// Windows
console.log(import.meta.dirname); // C:\alice

A flag that indicates if the current module is the main module that was called when starting the program under Deno.

if (import.meta.main) {
  // this was loaded as the main module, maybe do some bootstrapping
}

A function that returns resolved specifier as if it would be imported using import(specifier).

console.log(import.meta.resolve("./foo.js"));
// file:///dev/foo.js
