  PROJECT_ROOT - node rfc.js	next.js api route
  __dirname: /Users/{{PROJECT_PATH}}/node_modules/node-rfc/lib path_1.default.resolve(__dirname, ".."): /Users/{{PROJECT_PATH}}/node_modules/node-rfc	__dirname: /Users/{{PROJECT_PATH}}/.next/server/app/api/sap-rfc/test path_1.default.resolve(__dirname, ".."): /Users/{{PROJECT_PATH}}/.next/server/app/api/sap-rfc

Describe alternatives you've considered

• The error situation is in next.js api route, but it can also occur in other situations.
• Provides the ability to specify the 'node_modules/node-rfc' path directly.

• noderfc-bindings.ts

  try {
  const hasEnvValue = typeof process.env.NODE_RFC_MODULE_PATH !== "undefined";
  const modulePath = hasEnvValue
      ? process.env.NODE_RFC_MODULE_PATH
      : path.resolve(__dirname, "..");
  
  // eslint-disable-next-line @typescript-eslint/no-unsafe-call, @typescript-eslint/no-var-requires
  noderfc_binding = require("node-gyp-build")(modulePath) as NWRfcBinding;
  } catch (ex) {
  // ...
  }

• usage
  • .env file

    # .env
    NODE_RFC_MODULE_PATH=./node_modules/node-rfc

  • node env variable

    $ NODE_RFC_MODULE_PATH=./node_modules/node-rfc node rfc-execute.js
