Autoload Config for PostCSS

Last verified Sep 9, 2026 against postcss-load-config@6.0.1.

postcss-load-config ships CommonJS only. require("postcss-load-config") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 18. import "postcss-load-config" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("postcss-load-config") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 18.
2. From ES modules use the default import: import postcssLoadConfig from "postcss-load-config"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
