How can I run a build of React app? - reactjs

I did a build for a React app using npm run-script build and I need to run it. Using npm run webpack is returning an error. Excuse my being very new to React but I really need to know how to run this app. I hope you can help!
My package.json:
{
"name": "dashboard",
"version": "0.1.0",
"private": true,
"dependencies": {
"axios": "^0.16.2",
"downloadjs": "^1.4.7",
"fast-memoize": "^2.2.8",
"flow-bin": "^0.52.0",
"lodash": "^4.17.4",
"mapbox-gl": "^0.39.1",
"material-ui": "^0.18.7",
"moment": "^2.18.1",
"node-sass-chokidar": "^0.0.3",
"react": "^15.6.1",
"react-dom": "^15.6.1",
"react-mapbox-gl": "^2.5.0",
"react-redux": "^5.0.5",
"react-router": "^4.1.2",
"react-router-dom": "^4.1.2",
"react-router-redux": "next",
"react-tap-event-plugin": "^2.0.1",
"redux": "^3.7.2",
"redux-thunk": "^2.2.0"
},
"devDependencies": {
"react-emotion": "^7.2.2",
"react-scripts": "1.0.10",
"styled-components": "^2.1.2"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"flow": "flow"
}
Here are the folders and files of the built app

As I mentioned in comments.
npm run build uses react-scripts to create a build for you
To run in production:
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"flow": "flow",
"start:prod": 'node dist/app.js'
}

By looking at "react-scripts": "1.0.10", it seems you created the app using create-react-app.
create-react-app is using yarn by default. So you can run yarn then yarn build (same as npm install and then npm run build)
If you need change webpack configuration. The app have eject first. You can do it by yarn eject. And then you can edit the webpack config file.
Does this help?

Are you using create-react-app? If yes then run "npm run build" in your root folder. This command will run your app

How to remove warning by npm?

When I run npm install, I get the following error:
npm WARN eslint-config-react-app#2.1.0 requires a peer of eslint-plugin-jsx-a11y#^5.1.1 but none is installed. You must install peer dependencies yourself.
Here is what my package.json looks like:
{
"name": "name",
"version": "0.1.0",
"private": true,
"dependencies": {
"ajv": "^6.5.0",
"aws-amplify": "^0.4.0",

"react-router-dom": "^4.2.2",
"react-scripts": "1.1.4"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},

"eslint-plugin-import": "^2.11.0",
"eslint-plugin-jsx-a11y": "^6.0.3",
"eslint-plugin-react": "^7.8.2"
}
}
Does anyone know how to remove this error?
This is not an error, it is a WARNing
The easiest trial is delete node_modules directory and retype to see if it persists
npm install
Moreover you can use npm-install-peers to find and install required peer dependencies
npm install -g npm-install-peers
npm-install-peers
Also you can change the log level to error so that you won't see the warnings

sass not working in create-react-app

Repo: https://github.com/athimannil/create-app
It is working fine, npm start watch your .scss files and output .css files as expected.
Make sure to require the .css files in your components.
Since src/App.js still imports src/App.css, the styles become a part of your application. You can now edit src/App.scss, and src/App.css will be regenerated.
Also since .css files are now generated, you should remove them from your SCM.
At this point you might want to remove all CSS files from the source control, and add src/**/*.css to your .gitignore file.

The 2. version of create-react-app supports Sass now. Install node-sass (e.g. npm install node-sass) to enable it. Checkout this application's Navigation component.

yarn build just hangs when completed

I thought i had figured out what the problem was but alas, i did not. When running my build script yarn build or even npm run build the script builds just fine but the process never completes and just hangs... Does anyone have an idea on how to go about troubleshooting this sort of problem?
here's my package.json

How to access backend data in reactjs (via create-react-app's npm start)

So I can get the data if I npm run build my app and run it via it's usual address. But with npm start it doesn't know/(can't reach) the specified location.
So how might I go about doing this so it can work both ends?
package.json

"name": "reactjs",
"version": "0.1.0",
"private": true,
"homepage": "/reactjs/build",
"devDependencies": {
"lite-server": "^2.2.2",
"react-scripts": "0.8.4"
},
"dependencies": {
"datatables.net": "^1.4.2",
"datatables.net-dt": "^1.4.2",
"griddle-react": "^0.7.1",

},

"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject",
"dev": "lite-server -c config/bs-config.js"
}
}
Add proxy to it e.g.
"homepage": "/reactjs/build",
"proxy": "http://localhost/supermarkets
