luicfrr📚 Introduction
Trying to load a fresh installed package and got the error cannot use import statement outside a module? This packaged is the sollution for your problems.
I've created it after Googling a lot trying to find a sollution on how to import an ESM package in a big and consolidated CommonJS project... Migrate whole project to ESM architecture just to use a single package was not an option.
Is this package usefull to you? Support it buying me a coffee ☕ or giving a ⭐ on GitHub.
🧰 Installation
To install, you can use npm or yarn:
npm install commonjs-esm-loader
# or
yarn add commonjs-esm-loader
💡 Usage
OBS: Using pdfreader package as example because it was the package that makes me create this project, but it works with any ESM package you want to load.
JavaScript
import { importEsmModule } from 'commonjs-esm-loader'
async function myFunction() {
const { PdfReader } = await importEsmModule( 'pdfreader' )
// your package is loaded and ready to use :)
new PdfReader( ... )
}
TypeScript
import { importEsmModule } from 'commonjs-esm-loader'
// load package type so intellisense can work
import type PdfReaderType from 'pdfreader'
async function myFunction() {
const { PdfReader } = await importEsmModule<typeof PdfReaderType>( 'pdfreader' )
// your package is loaded, typed and ready to use :)
new PdfReader( ... )
}
