babel-plugin-transform-import-meta

Transforms import.meta for nodejs environments. This plugin supports transforming the following apis:

• import.meta.dirname
• import.meta.filename
• import.meta.resolve(specifier)
• import.meta.url

import.meta.dirname

console.log(import.meta.dirname);

Is replaced with

console.log(__dirname);

import.meta.filename

console.log(import.meta.filename);

Is replaced with

console.log(__filename);

import.meta.resolve(specifier)

console.log(import.meta.resolve(myCustomFunction('path', 'file')));

Is replaced with

console.log(require('url').pathToFileURL(require.resolve(myCustomFunction('path', 'file'))).toString());

import.meta.url

console.log(import.meta.url);

Is replaced with

console.log(require('url').pathToFileURL(__filename).toString());
