CommonJS CommonJS — require() works on every Node.js version we test
get-caller-file ships CommonJS only. require("get-caller-file") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js 6.* || 8.* || >= 10.*. import "get-caller-file" 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
- require("get-caller-file") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js 6.* || 8.* || >= 10.*.
- From ES modules use the default import: import getCallerFile from "get-caller-file"; then destructure. Named imports only work when Node.js can statically detect the exports.
- TypeScript: npm install -D @types/get-caller-file
