I'm trying to add CoreJS to a project for using as a polyfill. In the core js file, I have:
import 'core-js/stable';
import 'regenerator-runtime/runtime';
My babel config is:
{
presets : [
[
'@babel/env',
{
'useBuiltIns': 'entry',
'corejs' : 3,
'modules' : 'amd'
}
]
]
}
When the file compiles, the output js looks like:
require("core-js/modules/es.symbol");
require("core-js/modules/es.symbol.description");
require("core-js/modules/es.symbol.async-iterator");
...
The browser console errors out with:
Error: Module name "../es" has not been loaded yet for context: _. Use require([])
https://requirejs.org/docs/errors.html#notloaded
Changing the require statements to use arrays like RequireJS is used to solves the issue with that file, but continues to occur within core-js.
Example fix:
require(["core-js/modules/es.symbol"]);
I'm assuming there's an issue with Babel's AMD transformer, or maybe there's another solution to this.
