Load “vanilla” Javascript Libraries Into Node.js = 'unexpected Token Export'

Building on related issue: Load 'Vanilla' Javascript Libraries into Node.js I'm trying to load a 'Vanilla' Javascript library 'rsa.js' into NodeJS, using the method described by Ch

Solution 1:

The error 'Unexpected token export' is caused because the library is using

export default thingToExport;

instead of

module.exports = thingToExport

This is an ES6 feature not supported by Node (yet), so when Node tries to run the code, it throws an error.

How to solve: try modifying the last line of the library so it says module.exports = rsa;.

I should add, though, that eval is not a good way to load a library into your own code. That is what require is for. If you have installed this library with npm i and it is in your node_modules, you should be able to load it into your code with var rsa = require('rsa');.

Again though, if you're not transpiling the code, it may have problems with export default, so you will probably want to change that to module.exports either way.
