@atls/stack-trace and @atls/webpack-source-map publish ESM entrypoints starting with version 1.0.0. Import their APIs from an ESM project:
import { parse } from '@atls/stack-trace'
import { resolve } from '@atls/webpack-source-map'The synchronous parse and resolve APIs remain available. CommonJS consumers can stay on the 0.0.2 releases until they migrate to ESM.
