Dependency @antv/g6 is attempting to import Node built-in module util.

https://github.com/antvis/G6/blob/06da73019d1a6ca8e7481b4229cb85980d966557/src/plugins/timeBar/path.ts#L4

Consider import from @antv/util instead. As a front-end library there shouldn’t be any dependencies from nodejs.

BTW, vite’s rollup will show error:

Illegal reassignment to import 'mat3'
Illegal reassignment to import 'vec2'

But I haven’t find out which file causes this issue. Maybe related #2254.

Ok, I found a way to get a more detailed error log by using rollup, steps:

echo '{"private":true}' > package.json
npm install -D rollup @rollup/plugin-commonjs @rollup/plugin-node-resolve
npm install @antv/g6

rollup.config.js

import resolve from '@rollup/plugin-node-resolve';
import commonjs from '@rollup/plugin-commonjs';

export default {
  input: 'a.js',
  output: { format: 'es' },
  plugins: [resolve(), commonjs()]
};

a.js

export * as G6 from "@antv/g6"

rollup!

npx rollup -c rollup.config.js

outputs

(!) Illegal reassignment to import 'mat3'
node_modules\@antv\matrix-util\esm\mat3.js: (2:0)
1: import * as mat3 from '@antv/gl-matrix/lib/gl-matrix/mat3';
2: mat3.translate = function (out, a, v) {
   ^
3:     var transMat = new Array(9);
...

It looks like your esm bundle result is not sound to rollup. Also,

Error: 'ISystem' is not exported by node_modules\@antv\g-webgpu-core\es\ISystem.js, imported by node_modules\@antv\g-webgpu-core\es\index.js

(I guess should we edit the issue title to ‘can not use rollup to bundle this module’ or raise a new issue?)

I also have this error when I configure Rollup to use only the ES6 module of G6 (Version 4.1.4).

The file node_modules/@antv/g-webgpu-core/es/ISystem.js is empty, but the file node_modules/@antv/g-webgpu-core/es/ISystem.d.ts export the interface ISystem.
