Is this an ESM-first module now?

When bumping from 10.3.0 to 10.4.4 I encountered the following issue when building my project:

> Build error occurred
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /home/runner/work/monorepo/monorepo/website/node_modules/d3-array/src/index.js
require() of ES modules is not supported.
require() of /home/runner/work/monorepo/monorepo/website/node_modules/d3-array/src/index.js from /home/runner/work/monorepo/monorepo/website/node_modules/reaviz/dist/index.cjs.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /home/runner/work/monorepo/monorepo/website/node_modules/d3-array/package.json.

Is this an ESM-first module now?

In my opinion, this should be clearly stated in the documentation.

Also, since this breaks backward compatibility (given the current JS ecosystem), I think this should warrant a major version change; not a minor one.

I don’t wanna get too far ahead of myself, but d3 might have solved the problem for us.

The specific dep that’s throwing the error for me is d3-array, and according to your package.json, you have v3.0.4, and there is a new version, 3.1.1 available as of 1 month ago. According to the changelog, they have updated it to es6, so import should actually work now.

I’ll report back after some testing.
