in my package.json I have these scripts:
"scripts":
{
"lint": "./node_modules/.bin/eslint src",
"build": "npm run clean && npm run dev && npm run prod",
"tsc": "./node_modules/.bin/tsc",
"dev": "./node_modules/.bin/webpack --config webpack.dev.js",
"prod": "./node_modules/.bin/webpack --config webpack.prod.js",
"clean": "del /q inet-henge*.js* dist",
"watch": "./node_modules/.bin/webpack --config webpack.dev.js --watch",
"postinstall": "copy inet-henge.js \"..\\flask\\customer_topology\\static\""
}
But for some reason postinstall is completely ignored when i run npm run build. When I run it as standalone script, it runs, the file is copied to the new location. Path is correct. What could be the problem, I am on Windows
post<x> runs after <x> so postinstall runs after install and if you want a script to run after build it should be called postbuild See https://docs.npmjs.com/cli/v6/using-npm/scripts for more details.

Compiling takes more than 20-22 seconds. I trying to improve the compiling speed of typescript node backend.
I'm using windows 11 bash terminal, computer not very bad (Intel(R) Core(TM) i7-9750H CPU # 2.60GHz, 2592 Mhz, 6 Core, 12 thread). Same build completes much faster on macOS.
Here is the my scripts;
"scripts": {
"start": "npx ts-node",
"dev": "npx nodemon --watch src src/index.ts",
"production": "npx ts-node ./src/index.ts",
"build": "npx tsc -p tsconfig.json && npx tscpaths -p tsconfig.json -s ./src -o ./build",
"build:run": "npm run build && npm run production",
"lint": "tslint -c tslint.json --project tsconfig.json",
"test": "jest --config jest.config.js",
"watch": "npm run build && npm run start",
"watch:lint": "npm run lint -- --watch",
"watch:test": "npm run test -- --watch",
"watch:build": "npm run build -- --watch",
"watch:start": "npm run start -- --watch"
},
What would you recommend me?
I want to run a command like: npm run start:dev to make my node server runs but after webpack finished building bundles.
My current npm scripts are:
"scripts": {
"start": "node server/server.js",
"start:dev": "npm run build:prod & npm start",
"lint": "eslint *",
"build:dev": "webpack",
"build:prod": "webpack -p --env production",
"dev-server": "webpack-dev-server",
"test": "cross-env NODE_ENV=test jest --config=jest.config.json"
},
The current command will kick both operations together.
Typo: you don't actually want to use &, you want &&:
"start:dev": "npm run build:prod && npm start",
A single ampersand will background the run:build job and cause start to run concurrently.
I am using heroku/nodejs build pack.
this is how my scripts in package.json look like:
"scripts": {
"build": "webpack --config webpack.prod.js",
"server": "http-server public -p 3000 -a localhost -c 0",
"prod": "npm run build && npm run server",
"dev": "webpack-dev-server --config webpack.dev.js",
"lint": "eslint . --fix"
},
In procfile I have only one line of code:
web: npm run prod
Any ideas why am I seeing application error?
In regards to the error, I think that you should be using the environment variable $PORT i.e. http-server public -p $PORT -c 0 Make sure you have http-server in you deps and not your devDeps.
This might not be causing the error but you shouldn't do your build on run. Instead add the build step to a postinstall NPM script like below.
"scripts": {
"build": "webpack --config webpack.prod.js",
"postinstall": "npm run build",
"server": "http-server public -p $PORT -c 0",
"prod": "npm run server",
"dev": "webpack-dev-server --config webpack.dev.js",
"lint": "eslint . --fix"
},
This will ensure that your build gets run on deployment and not every time the node process starts.

please help my out how i increase size.
I had similar issue. I was using node version 8.x. Downgrading it to 6.11.0 resolved my issue.
Anyone know how to get node AWS beanstalk to run npm run build command after its does its npm install.
I have the following scripts in my package.json but it doesn't seem to run the build or the start command just the install
"scripts": {
"build": "cross-env NODE_ENV=production webpack --config ./webpack/webpack.prod.config.js --progress --colors",
"start": "node server/app.js",
"dev": "nodemon server/app.js"
},
