Any plans to release a native ES6 Module we can use directly in modern browsers?

E.g.

import printj from './node_modules/printj/printj.js'

We don't plan on removing the ES5/CJS bundle that currently exists. We use this in various sites that are built with webpack or rollup with the relevant CJS loader, so the only real case that needs an ES6-export version is the browser script module loader.

We could additionally add an ES6 module that would export the sprintf and vsprintf functions directly (for consistency with the browser, it would have to be called printj.mjs). This is actually pretty easy since the whole thing is built from smaller scripts anyway.

The usage would probably look like:

import { sprintf } from './node_modules/printj/printj.mjs'

OK, thanks.. well, in the meantime if anyone else would like to use printj in a native ES6 web app, here is a module you can use until printj supports native ES6 modules.

Included as printj.mjs in the repo and npm bundle.

https://oss.sheetjs.com/printj/tests/mjs.html is a demo (check the source, it's unminified)

https://plnkr.co/edit/yTANwhsAoStCw5dQoqwC?p=preview is a live version using unpkg:

import { sprintf } from 'https://unpkg.com/printj@1.2.0/printj.mjs';
sprintf("Hello %s", "World!");
