Require Node.js 12.20 and move to ESM

[antongolub]

• add named exports
• update all deps to the latest versions
• add Node.js v16 to test matrix
• apply xo --fix
• BREAKING CHANGE: require Node.js >= 12.20
• BREAKING CHANGE: drop default exports, remove all globby.* methods

Thanks for working on this.

You need to update index.d.ts (https://github.com/sindresorhus/typescript-definition-style-guide) and the readme for ESM too.

I can never decide how to handle named exports with async and sync methods:

• globby and globbySync
• globbyAsync and globbySync

The former looks nicer, but the latter is clearer. Any opinion?

[antongolub]

My guess is that for most users, the migration will look like this: const globby = require('globby') → import {globbyAsync as globby} from 'globby'. Well... I'd prefer just import {globby} from 'globby' instead.

[sindresorhus]

Alright. Let's go with globby for async and drop globbyAsync.

@sindresorhus, your turn

[zloirock]

@sindresorhus sorry, why do you avoid the default export here?

[fisker]

I guess for consistency import? But I think maybe we can export both named and default? export {globby as default, globby}

[sindresorhus]

It's weird to have one default and one named when there are two main exports. I only do default and named export mix when there's only one main export and some secondary exports (like error, or helper utilities).

No, there should be only one way to import the thing. Aliases create confusion and inconsistency.
