CommonJS CommonJS — require() works on every Node.js version we test
@ethersproject/networks ships CommonJS only. require("@ethersproject/networks") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "@ethersproject/networks" 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.
It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.
What to do
- require("@ethersproject/networks") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
- From ES modules use the default import: import networks from "@ethersproject/networks"; then destructure. Named imports only work when Node.js can statically detect the exports.
- TypeScript: types are bundled; install nothing extra.
