CommonJS CommonJS — require() works on every Node.js version
rollup-plugin-json ships CommonJS only. require("rollup-plugin-json") works everywhere. import "rollup-plugin-json" 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.
Deprecated: This module has been deprecated and is no longer maintained. Please use @rollup/plugin-json.
