"scripts": {
"server": " npm run watch --prefix server",
"client":" npm run start --prefix client",
"watch":" npm run client & npm run server",
"test": "echo \"Error: no test specified\" && exit 1"
},
npm run watch only runs the first command (npm run client) before & operator.
install this package:https://www.npmjs.com/package/npm-run-all and then "start": "npm-run-all -p watch-css start-js", where watch-css and start-js are npm scripts in my case

"scripts": {

how to run npm run build first and then npm start in a single command?
"scripts": {
"start": "node server.js",
"build": "webpack",
"start-dev" : "npm run build && npm run start"
},
I tried the command npm run start-dev. But only webpack is being compiled. The server isn't running.
I don't know why that doesn't work, but, anyway, you can try this:
"scripts": {
"start": "node server.js",
"build": "webpack",
"start-dev" : "webpack && node server.js"
}
npm i npm-run-all
this package never run into issue. You can add as many as commands
"dev:start": "npm-run-all build start",
locally, i start my app using the following commands:
cd react-web
sudo npm run postinstall
export REACT_APP_CUSTOMER_ENVIRONMENT=envvariable
npm start
So, now i want to push this live through heroku. BUT, i need to set the start scripts in my package.json
so i have two package.json, one in the root directory, and one in react-web.
in the root directory, i wrote this start-script:
"scripts": {
"test-web": "cd react-web && npm test && cd ..",
"test": "npm run test-web",
"start": "cd react-web && export REACT_APP_CUSTOMER_ENVIRONMENT=gianlucaherokutest && npm start"
},
and in the react-web package.json, this:
"scripts": {
"start": "node checkEnvironmentForBuild && react-app-rewired start",
"build": "node checkEnvironmentForBuild && react-app-rewired build",
"deploy": "aws s3 sync build/ s3://YOUR_S3_DEPLOY_BUCKET_NAME --delete",
"postdeploy": "aws cloudfront create-invalidation --distribution-id YOUR_CF_DISTRIBUTION_ID --paths '/*' && aws cloudfront create-invalidation --distribution-id YOUR_WWW_CF_DISTRIBUTION_ID --paths '/*'",
"postinstall": "npm link ../shared",
"test": "node checkEnvironmentForBuild && react-app-rewired test",
"eject": "react-scripts eject"
},
can someone give me some advice on why it isn't working? When I run the app using everything above, it gives me this error:
2021-04-19T21:12:11.796818+00:00 app[web.1]: FATAL ERROR: MarkCompactCollector: young object promotion failed Allocation failed - JavaScript heap out of memory
any ideas?
when the status is online i am running the port on 8014 its still not running
when i use pm2 start tools/srcServer.js
"scripts": {
"prestart": "babel-node tools/startMessage.js",

}
I am running the node with npm start I need to run the node to run run the server forever.
I tried using the command "forever start -c "npm start" ./" its not showing
To run npm start from pm2 you can run pm2 start npm -- start. This will run any command that is written within package.json start section.
Why don't you try to use PM2 (Node process manager: http://pm2.keymetrics.io/)?
I use the following project which use webpack
https://github.com/Hashnode/mern-starter
I want to deploy it (to prod) i get error
Error: Cannot find module './dist/manifest.json'
This error is coming from https://github.com/Hashnode/mern-starter/blob/master/index.js
But I dont see the dist folder in the project, why, and how should I build it?
I believe that the Dist folder should be created during the build time (manification etc) so how should I trigger it ?
This is the package.json
{
"name": "mern-starter",
"version": "2.0.0",
"description": "Boilerplate project for building Isomorphic apps using React and Redux",
"scripts": {
"test": "cross-env NODE_ENV=test PORT=8080 MONGO_URL=mongodb://localhost:27017/mern-test node_modules/.bin/nyc node --harmony-proxies node_modules/.bin/ava",
"watch:test": "npm run test -- --watch",
"cover": "nyc npm run test",
"check-coverage": "nyc check-coverage --statements 100 --branches 100 --functions 100 --lines 100",
"start": "cross-env BABEL_DISABLE_CACHE=1 NODE_ENV=development nodemon index.js",
"start:prod": "cross-env NODE_ENV=production node index.js",
"bs": "npm run clean && npm run build && npm run build:server && npm run start:prod",
"build": "cross-env NODE_ENV=production webpack --config webpack.config.prod.js",
"build:server": "cross-env NODE_ENV=production webpack --config webpack.config.server.js",
"clean": "rimraf dist",
"slate": "rimraf node_modules && npm install",
"lint": "eslint client server"
},
I think that the start:prod should trigger it in the webpack but
its not happing ...any idea ?
As per the comments and the documentation:
Building the dist folder is done either via npm run bs or npm run build && npm run build:server (which is what npm run bs executes).
Starting the production build should be done via npm run start:prod (or by copying the commands from the package.json file: cross-env NODE_ENV=production node index.js)
I want to be able to execute the command script1 in a project directory that will run node script1.js.
script1.js is a file in the same directory. The command needs to be specific to the project directory, meaning that if I send someone else the project folder, they will be able to run the same command.
So far I've tried adding:
"scripts": {
"script1": "node script1.js"
}
to my package.json file but when I try running script1 I get the following output:
zsh: command not found: script1
Does anyone know the steps necessary to add the script mentioned above to the project folder?
*Note: the command can not be added to the bash profile (cannot be a machine specific command)
Please let me know if you need any clarification.
Custom Scripts
npm run-script <custom_script_name>
or
npm run <custom_script_name>
In your example, you would want to run npm run-script script1 or npm run script1.
See https://docs.npmjs.com/cli/run-script
Lifecycle Scripts
Node also allows you to run custom scripts for certain lifecycle events, like after npm install is run. These can be found here.
For example:
"scripts": {
"postinstall": "electron-rebuild",
},
This would run electron-rebuild after a npm install command.
I have created the following, and it's working on my system. Please try this:
package.json:
{
"name": "test app",
"version": "1.0.0",
"scripts": {
"start": "node script1.js"
}
}
script1.js:
console.log('testing')
From your command line run the following command:
npm start
Additional use case
My package.json file has generally the following scripts, which enable me to watch my files for typescript, sass compilations and running a server as well.
"scripts": {
"start": "concurrently \"sass --watch ./style/sass:./style/css\" \"npm run tsc:w\" \"npm run lite\" ",
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"typings": "typings",
"postinstall": "typings install"
}
Steps are below:
In package.json add:
"bin":{
"script1": "bin/script1.js"
}
Create a bin folder in the project directory and add file runScript1.js with the code:
#! /usr/bin/env node
var shell = require("shelljs");
shell.exec("node step1script.js");
Run npm install shelljs in terminal
Run npm link in terminal
From terminal you can now run script1 which will run node script1.js
Reference: http://blog.npmjs.org/post/118810260230/building-a-simple-command-line-tool-with-npm
Lets say in scripts you want to run 2 commands with a single command:
"scripts":{
"start":"any command",
"singleCommandToRunTwoCommand":"some command here && npm start"
}
Now go to your terminal and run there npm run singleCommandToRunTwoCommand.
Suppose I have this line of scripts in my "package.json"
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"export_advertisements": "node export.js advertisements",
"export_homedata": "node export.js homedata",
"export_customdata": "node export.js customdata",
"export_rooms": "node export.js rooms"
},
Now to run the script "export_advertisements", I will simply go to the terminal and type
npm run export_advertisements
Example:
"scripts": {
"ng": "ng",
"start": "ng serve",
"build": "ng build --prod",
"build_c": "ng build --prod && del \"../../server/front-end/*.*\" /s /q & xcopy /s dist \"../../server/front-end\"",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e"
},
As you can see, the script "build_c" is building the angular application, then deletes all old files from a directory, then finally copies the result build files.
