Error: Cannot find module ' react-hot-loader/babel' While deploying to heroku about express-react-boilerplate HOT 3 OPEN

Have you tried heroku config:set NPM_CONFIG_PRODUCTION=false

from express-react-boilerplate.

Yes, I did that but there were few more issues with port binding as this command deploy the complete app including devdependencies which also increases the size from 34 MB to 88MB

from express-react-boilerplate.

I updated package.json. You can change "scripts" option as belows.

"scripts": {
"start": "babel-node server/app.js",
"clean": "rimraf node_modules && rimraf dist && npm install",
"webpack:dev": "cross-env NODE_ENV=development webpack --config ./webpack/webpack.config.dev.js",
"webpack:prod": "cross-env NODE_ENV=production NODE_OPTIONS=--openssl-legacy-provider webpack --config ./webpack/webpack.config.prod.js",
"build:dev": "rimraf dist && npm run webpack:dev && npm run start",
"build": "rimraf dist && npm run webpack:prod && npm run start",
"migrate": "knex migrate:latest",
"migrate:make": "knex migrate:make",
"migrate:rollback": "knex migrate:rollback",
"lint": "eslint client server; exit 0"
},

from express-react-boilerplate.
