[question] ESM import bundle size

[sergchernata]

My import is as follows, bundled with webpack:

import bb, { spline } from "billboard.js"; // 3.10.3

With this import, my production bundle size increases by a little over 1MB. Does that sound right or am I missing something else?

[netil]

not the current v3 version, but the build size measured on v2, we got as follows results.

The bundle size may differ according your webpack or usage configuration environment.
And usually on webpack environment, non imported modules are tree-shaken to cut down from the bundling.
