Add default export

[andywer]

Make ES module - compatible and allow TypeScript users to easily use the package.

This will work after merging the PR:

import ms from 'ms'

I am not a big fan of those double CJS / ES exports myself, but there are a couple of scenarios when you have basically got no other choice.

Update: I just learned there is now finally a way around that issue, see this tweet.

Feel free to turn down the PR if you want :)

Glad you found a fix! Generally, this should be resolved by Webpack anyway... 😊

@andywer how did you get this to work? in NodeJS? Angular?

[andywer]

@ericsnap Just set the esModuleInterop option to true in your tsconfig.json. See here. It's a TypeScript thing, so it works everywhere: frontend, backend, wherever you use TS.

@andywer thanks. yeah, I was having issues compiling it kept saying that it did not have a default export. I did have to also set allowSyntheticDefaultImports. Does the module setting or the target have any impact on this?

[andywer]

@ericsnap Try:

{
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "module": "commonjs",
    // ...
}
