unist utility to visit nodes

Last verified Sep 9, 2026 against unist-util-visit@5.1.0. JSON

ESM-only ESM-only since 3.0.0 — last CommonJS version is 2.0.3

unist-util-visit dropped its CommonJS build in 3.0.0 (April 2021). The last version you can require() on every Node.js version, including 18 and older, is 2.0.3, published Jul 11, 2020.

On Node.js 20.19+, 22.12+ and every newer release, require("unist-util-visit") works anyway: Node can load synchronous ES modules through require(). Verified on Node 20, 22, 24, 26. Node.js 18 and older still fail with ERR_REQUIRE_ESM.
