bash script is not running when I type $ npm build, in console

Question

I want to write a batch script (build.sh) to install dependencies, run front end, and run back end at the same time

package.json file

"scripts": {
  "dev": "nodemon server.js",
  "client": "cd client && npm start",
  "start": "concurrently \"npm run dev\" \"npm run client\" ",
  "build": "chmod +x ./build.sh"
},

build.sh file

#!/bin/bash

npm run build

npm i aws-sdk body-parser concurrently cors dotenv express joi mongoose multer multer-s3 

cd client
npm i axios bootstrap config jquery node-modules react react-bootstrap react-dom react-scripts redux redux-form redux-thunk web-vitals 
cd ..

npm start

I'm not sure what I'm missing to have it run properly? Thanks in advance!

When I type $ npm build, into the command line (in the app's directory of course) I get this:

Usage: npm <command>

where <command> is one of:
    access, adduser, audit, bin, bugs, c, cache, ci, cit,

Did you mean this?

Just to be clear, your error message doesn't appear to come from typing $ npm build, but npm build. $ is not part of the command, just a convention for representing the user's shell prompt. — chepner

build is not a valid CLI command for npm. To run the build script defined in the package.json, do $ npm run build.

thanks, $ npm run build, does make it run. but it only prints: "> chmod +x ./build.sh" rather than load the dependancies and run the app.

It runs the associated command you've specified in package.json. What did you expect it to do?

tgall Over a year ago

Sure, that's because all you've asked it to do is add executable permissions to the file build.sh. If you want to run that script as well, replace the definition of build in the package.json with chmod +x ./build.sh && ./build.sh

Seb Over a year ago

interesting, and thank you that worked. i'm curious as to why you'd have to add "&& ./build.sh" a second time. regardless, it works, so thanks again.

"build": "chmod +x ./build.sh"

should be:

"build": "./build.sh"

chmod +x just makes the build.sh file executable, it doesn't actually run it.

Then to run the build command from npm you have to use npm run build like the other answer said.
