Only use it when you are shipping native ES modules and you need compatibility exclusively with tools that don't support the Import Attributes syntax ( import pkg from "./package.json" with { type: "json" } ) but support the old Import Assertions syntax ( import pkg from "./package.json" assert { type: "json" } ), such as Chrome 91 - 122 and Node.js ^16.14 || ^18 || ^20 < 20.10 .
