Please try to answer the following questions:

• What version of Neutrino are you using? 9.0.0-rc.1
• Are you trying to use any presets? If so, which ones, and what versions? "@neutrinojs/airbnb-base": "9.0.0-rc.1", "@neutrinojs/jest": "9.0.0-rc.1", "@neutrinojs/library": "9.0.0-rc.1",
• Are you using the Yarn client or the npm client? What version? npm, but it seems like yarn is used under the hood by neutrino when creating the project.
• What version of Node.js are you using? 10.15.3
• What operating system are you using? Ubuntu 16.04 LTS
• What did you do? Migration from neutrino 9.0.0-rc.0 to 9.0.0-rc.1
• What did you expect to happen? Node Library should work as in 9.0.0-rc.0
• What actually happened, contrary to your expectations? ReferenceError: regeneratorRuntime is not defined

Can you share any of the application code? I am wondering what functionality you may be using that may need to be polyfilled. According to the docs for library:

Important! This preset does not include @babel/polyfill for size reasons. If you need polyfills in your library code, consider importing @babel/polyfill, core-js, or other alternative.

I am using neutrino together with lerna in a monorepo. My library is just a little boilerplate to create web servers with hapi.

import fs from 'fs';
import Hapi from 'hapi';
import pino from 'hapi-pino';
import Inert from 'inert';
import Vision from 'vision';
import HapiSwagger from 'hapi-swagger';
import Pack from '../../package';

import systemRoutes from './routes'; // tiny hello world route

const prettyPrint = true; // process.env.NODE_ENV !== 'production';
const logger = require('pino')({ prettyPrint });

// TODO: enable TLS by removing the following line
process.env.NODE_TLS_REJECT_UNAUTHORIZED = 0;

const {
  HOST, PORT, TLS_KEY, TLS_CERT, CORS,
} = process.env;

function buildContext() {
  const context = {
    host: HOST || '0.0.0.0',
    port: PORT || 6781,
    routes: {
      cors: String(CORS) !== 'false',
    },
  };

  if (TLS_KEY && TLS_CERT) {
    const tls = {
      key: fs.readFileSync(TLS_KEY),
      cert: fs.readFileSync(TLS_CERT),
    };
    return { ...context, ...tls };
  }

  return context;
}

class Server {
  constructor({ context, routes, info }) {
    this.info = info;

    this.context = { ...buildContext(), ...(context || {}) };
    this.server = Hapi.server(this.context);

    logger.info(systemRoutes, routes);
    this.routes = systemRoutes;
    if (routes && routes.length > 0) {
      this.routes = [...systemRoutes, ...routes];
    }
    logger.info(this.routes);
    this.server.route(this.routes);
  }

  async start() {
    try {
      await this.server.register([
        Inert,
        Vision,
        {
          plugin: HapiSwagger,
          options: {
            info: this.info || {
              title: 'API Documentation',
              version: Pack.version,
            },
          },
        },
        {
          plugin: pino,
          options: {
            prettyPrint,
            // Redact Authorization headers, see https://getpino.io/#/docs/redaction
            redact: ['req.headers.authorization'],
          },
        },
      ]);

      await this.server.start();
    } catch (err) {
      logger.fatal(err);
      process.exit(1);
    }
  }
}

export default Server;

This is how I use the library.

import Node from 'full-stack-node';

const routes = [];

const context = {
  port: process.env.PORT || 8200,
};

const server = new Node.Server({ context, routes });

server.start();

Seems like this is the same error: 1417

So the issue is in neutrino's library preset and react-component preset. Some how they cannot handle async/await.

@eliperelman Thanks! Finally I got it...

import "core-js/stable";
import "regenerator-runtime/runtime";
