New Node.js ESM support ?

[fraxken]

Hi,

Is there is way for Husky to work with the new native ESM support of Node.js ? I'm working on a Node.js monitoring agent where we use Node ESM but husky stop working because of the type: "module" in the package.json (i guess).

Doc for Node.js ESM: https://nodejs.org/api/esm.html

$ git commit -m "fix: remove nsecure-result"
husky > commit-msg (node v14.2.0)
F:\Code\SlimIO\Core\node_modules\@commitlint\cli\lib\cli.js:124
        throw err;
        ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: F:\Code\SlimIO\Core\commitlint.config.js
require() of ES modules is not supported.
require() of F:\Code\SlimIO\Core\commitlint.config.js from F:\Code\SlimIO\Core\node_modules\cosmiconfig\node_modules\import-fresh\index.js is an ES module file as it is a .js file whose nearest parent package.jso
n contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename commitlint.config.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from F:\Code\SlimIO\Core\package.json.

I tried a lot of things but nothing work so far.

Same issue here. Using node 12 and husky in a type: module package and when running npm install I get this error:

Must use import to load ES Module: C:\Users\username\Projects\project\husky.config.js
require() of ES modules is not supported.

Instead rename husky.config.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from C:\Users\username\Projects\project\package.json.
husky > Failed to install

Not sure if this is a cosmiconfig issue in the first place?! There's an open issue regarding mjs and cjs files as well.
