Jest utilities for Styled Components

Last verified Sep 9, 2026 against jest-styled-components@7.4.0.

jest-styled-components ships CommonJS only. require("jest-styled-components") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 12. import "jest-styled-components" 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("jest-styled-components") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 12.
2. From ES modules use the default import: import jestStyledComponents from "jest-styled-components"; then destructure. Named imports only work when Node.js can statically detect the exports.
