package.json
{
..
"scripts": {
"prestart": "gulp",
"start": "webpack-dev-server"
},
..
}
i need to pass appname to both gulp as well as webpack-dev-server.
When i am doing npm start -- --app=todo
the argument --app=todo is only available to webpack-dev-server not in gulp.
Any solution to pass argument to both the task.
I tried "scripts" : {"start" : "gulp & webpack-dev-server"} as well.
I had the same question and came upon this conversation. It appears that this is deliberately not possible.

For instance, I want to run jest tests for one of my packages.
I set up the test script in the child package.json:
"test" : "jest"
However when I got to the package directory and run:
npm test
I get:
sh: jest: command not found
This makes sense because I've only installed jest in the root package since it is a dev dependency.
What do I need to do to make the npm package jest available in the child packages?
We're using an npm package called env-cmd https://www.npmjs.com/package/env-cmd to run scripts from root level in packages.
our root package.json looks something like this:
{
"name": "#myAwesomeApp/root",
"private": true,
"devDependencies": {
"env-cmd": "^10.1.0",
"lerna": "^5.0.0"
},
"dependencies": {
[...]
},
"workspaces": [
"packages/*"
],
"scripts": {
"internal:warning": "echo \"\n\t\\\\033[32m! ANY NOTIFICATION !\n\"",
"jest": "npm run internal:warning && env-cmd --silent lerna run test"
}
}
How can I pass arguments from one script to the other
using npm-run-all (to run in parallel)
scripts:{
"start":"run-p dev watch -- --theme=$themeId",
"dev": "webpack",
"watch": "theme watch --env=$themeId"
}
Then calling start like:
npm run start theme=2233
But it wouldn't pass the argument to the watch argument
Using ${npm_config_themeId}
"scripts": {
"start": "run-p dev watch",
"watch": "theme watch --env=${npm_config_theme}",
}
Then calling
npm run start -theme=123
I want to run an npm script (like npm start) using forever. I know this command:
forever start -c "npm start" /path/to/app/dir/
But how can I ad that into a json file like this
[
{
// App1
"uid": "app1",
"append": true,
"watch": false,
"script": "-c npm start", // doesn't work
"sourceDir": "/path/to/app/dir"
}
]
You cannot add directly npm start to the script, as you already know that script attribute is only to specify the main entry point of your application, probably you need to use some args.
"scripts" : { "start" : "node server.js" } }
where server.js is :-
http.createServer(...).listen(process.env.npm_package_config_port)
I am using npm precommit hook, but it is not stopping a file with issues to be committed, nor am I getting the message "Pre commit checks" when I try to commit a file.
Package Json:
{
"name": "myfolder",
"version": "1.0.0",
"description": "",
"main": "",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 0",
"precommit-msg": "echo 'Pre-commit checks...' && exit 0",
"lint": "csslint global/css"
},
"author": "SR",
"license": "ISC",
"dependencies": {
"csslint": "^1.0.4",
"jshint": "^2.9.4",
"pre-commit": "^1.2.2"
},
"pre-commit": [
"precommit-msg",
"lint"
],
"devDependencies": {
"pre-commit": "^1.2.2"
}
}
Please, make sure that your 'package.json' file is in the same folder, where '.git' folder is (where git repository was initialized). When you install 'pre-commit' package, 'pre-commit' file should appear under '.git/hooks/'.
Just FYI I had this issue because the pre-commit file was missing in the hooks folder.
Running npm i pre-commit --save-dev again created the file and solved it for me.
Have't managed to implement it with few "pre-commit" NPM modules (#fastify/pre-commit, monorepo-staged-precommit) so implemented it "manually" with adding tools/pre-commit.sh file into repo with content like:
#!/bin/sh
DIR='web'
echo "Pre-commit actions (NPM tests for $DIR)..."
cd $DIR && npm run test
and updating package.json with:
"scripts": {
"test",
"install-precommit": "cp ../tools/pre-commit.sh ../.git/hooks/pre-commit"
This solution has some limitations (like instead of automatic installation need to ask somewhere in "README" about npm run install-precommit and I'm not sure how it would work on Windows especially without Git Bash) but it worked for me.
Notes:
Other pre-commit NPM packages either didn't work as well or asked for NVM and other extra tools which I don't want devs to install for such small task.
pre-commit.sh may has any name and don't be executable - "install-precommit" task and git care about.
As shown in the screen shot below I am not able to run gulp to concat the JavaScript files. Its saying that gulp is not defined.
I have tried the following commands:
npm install -g gulp
npm install gulp
npm install gulp --save-dev
I have also set the environment variables as following:
C:\Users\<user>\AppData\Roaming\npm;C:\Python27;C:\Users\<user>\AppData\Roaming\npm\node_modules;C:\Users\<user>\AppData\Roaming\npm\node_modules\gulp;
var concat = require('gulp-concat');
var rename = require('gulp-rename');
var uglify = require('gulp-uglify');
//script paths
var jsFiles = 'scripts/*.js',
jsDest = 'dist/scripts';
gulp.task('scripts', function() {
return gulp.src(jsFiles)
.pipe(concat('scripts.js'))
.pipe(gulp.dest(jsDest));
});
you just need to install and require gulp locally, you probably only installed it globally
At the command line
cd <project-root> && npm install --save-dev gulp
In your gulpfile.js
var gulp = require('gulp');
this is a different dependency than the command line dependency (that you installed globally). More specifically, it is the same NPM package, but the command line program will execute code usually from a different entry point in the NPM package then what require('X') will return.
If we go to the package.json file in the Gulp project on Github, it will tell the whole story:
{
"name": "gulp",
"description": "The streaming build system",
"version": "3.9.1",
"homepage": "http://gulpjs.com",
"repository": "gulpjs/gulp",
"author": "Fractal <contact#wearefractal.com> (http://wearefractal.com/)",
"tags": [ ],
"files": [
// ...
],
"bin": {
"gulp": "./bin/gulp.js"
},
"man": "gulp.1",
"dependencies": {
// ...
},
"devDependencies": {
// ...
},
"scripts": {
"prepublish": "marked-man --name gulp docs/CLI.md > gulp.1",
"lint": "eslint . && jscs *.js bin/ lib/ test/",
"pretest": "npm run lint",
},
"engines": {
"node": ">= 0.9"
},
"license": "MIT"
}
so at the command line:
$ gulp default
will execute this:
"bin": {
"gulp": "./bin/gulp.js"
},
on the other hand, require('gulp') in your code will return the value of this:
https://github.com/gulpjs/gulp/blob/master/index.js
normally we see this in a package.json file as:
"main": "index.js"
but since this is the default, they just omitted it (which is dumb IMO, better to be explicit, but they aren't the first project I have seen take the lame shorthand route.).
Its occurs on Windows and usually one of the following fixes it:
If you didn't, run npm install gulp on the project folder, even if
you have gulp installed globally.
Normally, It isn't a problem on Windows, but it could be a issue with
the PATH. The package will try to get the PATH from the environment,
but you can override it by adding exec_args to your gulp settings.
For example, on Ubuntu:
"exec_args": {
"path": "/bin:/usr/bin:/usr/local/bin"
}
Hope It will be OK.
