In some case I need to start a node.js process with the -r option to preload a ESM library mriya. The library can be installed with the command npm i mriya, and the command I want to run is node -r mriya. It works when I require a CommonJS module, but when it is a ES module the command will fail with the following message
[Error [ERR_REQUIRE_ESM]: require() of ES Module mriya-test/node_modules/mriya/dist/mriya.js not supported.
Instead change the require of mriya.js in null to a dynamic import() which is available in all CommonJS modules.] {
code: 'ERR_REQUIRE_ESM'
}
Is there alternative option for -r to use with the ES Module, or is there any workaround I can use? Thank you.
node --experimental-loader your-esm-module

You can omit experimental- too:
node --loader your-esm-module
