Case
- Goal
- require() an ESM-only npm package from CommonJS without ERR_REQUIRE_ESM or ERR_REQUIRE_ASYNC_MODULE FIX
- Packages
- p-limit 7.3.1 yoga-layout 3.2.1
- Environment
- node 22
- Created
- 2026-08-13T14:19:50Z
Contract
- run a CommonJS file that require()s both ESM-only packages and assert it exits nonzero
- assert the failure is ERR_REQUIRE_ASYNC_MODULE, whose message is that require() cannot be used on an ESM graph with top-level await
- assert the same run proves the quieter half: on Node 22.12 and newer require('p-limit') returns the module namespace, so calling it raises TypeError: pLimit is not a function
- assert the cached dynamic import() resolves to a single namespace whose default export carries Yoga.Node, which the namespace itself does not expose
- assert the dynamic-import path computes a real flexbox layout: three flex-grow columns in a 240 by 60 row with a 12px gap land at x 0, 84 and 168, each 72 by 60
- assert p-limit loaded through the same dynamic import caps concurrency at 2 across 6 tasks and preserves input order
