node.js - Why is Heroku running a webpack process when I am using express.js? -


i uninstalled webpack , removed webpack.config.js file use express.js heroku. after committing , pushing heroku, log reads this:

$ heroku logs 2017-09-10t17:42:43.224045+00:00 heroku[web.1]: state changed crashed starting 2017-09-10t17:42:02.000000+00:00 app[api]: build succeeded 2017-09-10t17:42:47.480825+00:00 heroku[web.1]: starting process command `node ./node_modules/webpack-dev-server/bin/webpack-dev-server.js` 2017-09-10t17:42:50.050087+00:00 app[web.1]: module.js:471 2017-09-10t17:42:50.050108+00:00 app[web.1]:     throw err; 2017-09-10t17:42:50.050108+00:00 app[web.1]:     ^ 2017-09-10t17:42:50.050109+00:00 app[web.1]:  2017-09-10t17:42:50.050110+00:00 app[web.1]: error: cannot find module '/app/node_modules/webpack-dev-server/bin/webpack-dev-server.js'

the starting process in log trying initiate webpack ^, in procfile have this:

web: node server.js

to confirm that, here heroku ps

$ heroku ps === web (free): node server.js (1) web.1: 2017/09/10 14:41:56 -0400 (~ 27m ago)

package.json:

{   "name": "youtube-instant-search",   "version": "1.0.0",   "description": "renders youtube videos after keystrokes",   "main": "index.js",   "repository": "git@github.com:mattwarren10/youtube-instant- search.git",   "scripts": {     "start": "node server.js"   },   "author": "",   "license": "isc",   "devdependencies": {     "babel": "^5.8.29",     "babel-cli": "^6.26.0",     "babel-core": "^6.26.0",     "babel-eslint": "^7.2.3",     "babel-loader": "^6.4.1",     "babel-preset-env": "^1.6.0",     "babel-preset-es2015": "^6.24.1",     "babel-preset-es2016": "^6.24.1",     "babel-preset-react": "^6.24.1",     "babel-preset-stage-2": "^6.24.1",     "babelify": "^7.3.0",     "bootstrap": "^4.0.0-alpha.6",     "browserify": "^14.4.0",     "css-loader": "^0.28.7",     "eslint": "^4.6.1",     "node-sass": "^4.5.3",     "rimraf": "^2.6.1",     "sass-loader": "^6.0.6",     "style-loader": "^0.18.2"   },   "dependencies": {     "@types/react-addons-create-fragment": "^0.14.17",     "babel-preset-stage-1": "^6.1.18",     "core-js": "^2.5.1",     "express": "^4.15.4",     "lodash": "^3.10.1",     "prop-types": "^15.5.10",     "react": "^0.14.3",     "react-dom": "^0.14.3",     "react-intl": "^2.3.0",     "react-redux": "^4.0.0",     "redux": "^3.0.4",     "youtube-api-search": "0.0.5"   } }

server.js:

var express = require('express'); var app = express(); var path = require('path');  app.use(express.static(path.join(__dirname))); app.use("/style", express.static(__dirname));  // viewed @ based directory http://localhost:8080/ app.get('/', function (req, res) {   res.sendfile(path.join(__dirname + 'index.html')); });  app.listen(process.env.port || 8080);

does take time heroku update? what's going on?

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
