feat: Support native esm

[odanado]

Close #2310

Description

This error is caused by the bundler treating the .es.js file as a CJS (faux ESM).

Error: require() of ES Module node_modules/d3-interpolate/src/index.js from node_modules/@nivo/core/dist/nivo-core.cjs.js not supported. Instead change the require of index.js in node_modules/@nivo/core/dist/nivo-core.cjs.js to a dynamic import() which is available in all CommonJS modules.

I changed the extension of the .es.js file to .mjs so it would always be treated as an ES Module.

Changes

add ext for lodash

Since the extension cannot be omitted in ES Modules, I changed it to indicate it.

use .mjs for esm files

Changing the file extension to .mjs will treat these files as ES Modules.

add exports field

The modules field in package.json is a non-standard feature. I have added an exports field to replace it.

(using next / sst). ( it works with warnings)

The original error was in core, yes? so after your bar install I did:
npm i https://pkg.pr.new/odanado/nivo/@nivo/core@2

@msimonc
I tried installing @nivo/core in a project with the following package.json.

{
  "name": "example",
  "type": "module",
  "dependencies": {
    "react": "^19.0.0-rc-e56f4ae3-20240830"
  }
}

Since the same error occurs with both @nivo/core installations, this patch does not cause your error.

This error is probably caused by this line in @nivo/core.
