I would like to command "electron-packer ." (it takes some time) and then "asar pack app app.asar"
Is it possible to do this?
Or should I simply wait for the first one and command the second?
You can queue commands like this.
npm run pack1 && npm run pack2
Or you can add another line that does the above and just run that alone.
"scripts": {
"pack": "npm run pack1 && npm run pack2"
}
Add this inside your "scripts" and you can just run npm run pack to run both of those commands.

I really need help on this, couldn't find much examples on google.
For example:
I have this web project. Inside this project there is, app.js, views/home.ejs, some npm packages and etc...
This project, we are not allowed to type "npm install" "npm start" to run our project or we get a zero. The teacher will only type 1 line in terminal which is "run app.py" for python or "run js app" to run our code, will not install packages on localhost.
Wants us to make a textfile to automatically install all packages in the background and run the application automatically? How would I do that?
For example in text file:
inside TXT.FILE {
#1 run "npm install express" in terminal
#2 run "npm install body-parser" in terminal
#3 run "node app.js" in terminal
#4 also run "ls"
}
Basically just call terminal commands in a text file. A text file that will automatically execute them in order.
You have two options.
Add this into your package.json file
...
"scripts": {
...
"start": "npm install express && npm install body-parser && node app.js && ls"
},
Now you can use npm start to run all these commands at one go.
Add a bash script in your project directory.
The file should be named your-script-name.sh.
Inside add
#!/bin/bash
npm install express && npm install body-parser && node app.js && ls
You can run the script using ./your-script-name.sh in your terminal.
"scripts": {
...
"start": "npm install express && npm install body-parser && node app.js && ls"
},
Yes this works very well, tested it! Thank you.
This calls terminal commands under 1 line of code!
I have three scripts in package.json:
Watch server TypeScript
Nodemon
Webpack
"scripts": {
"watch-server": "tsc --watch --project ./server/tsconfig.json",
"watch-node": "nodemon --watch ./server/build/ --watch ./server/templates -e js,json,pug",
"watch-client": "webpack --config ./webpack/webpack.dev.conf.js --watch"
}
Everytime I start my computer and open VS Code I need to open three separate PowerShell terminals and type in those commands one-by-one. Is there any way to launch these three separate terminals with their own commands in one shell command? Maybe via tasks.json?
On linux or any bash terminal, you can use && to combine multiple commands, i
You can do as
npm run watch-server && npm run watch-node && npm run watch-client
A quick google search for powershell suggested using semicolon
so on powershell you can do something like below if using && does not work
npm run watch-server;npm run watch-node ; npm run watch-client
Also keep in mind, you can additionally add fourth command in your npm scripts in package.json where you can use one of these combined commands which works for you, like
start-all: npm run watch-server && npm run watch-node && npm run watch-client
and then run
npm run start-all
I have a scenario where I have to run three npm script to achieve some result in my application. I combined them in one npm script. This is my package.json:
"scripts": {
"setup": "npm install && npm run some-script && npm install",
"some-script": "gulp some-other-script"
}
what I would like to do is to pass arguments to setup script from command line which will be passed further to the some-script script.
If I run npm run script -- --abc=123 the arguments are added at the end of the script but I would like to pass it to specific script (in this case to npm run some-script). I also tried to rewrite script definition like this:
"setup": "npm install && npm run some-script -- --sample=sample&& npm install" but with no luck.
I'm aware of shell functions (described here: Sending command line arguments to npm script and here https://github.com/npm/npm/issues/9627) but I need a solution which will work cross-platform.
Is there a way to do that?
Ok I found a work around.
1st goal was to be able to use some script with arguments, and cascade this to the calls of other scripts :
npm run main -- --arg1
"main": "npm run script1 && npm run script2"
Problem with this approach is that the cascading would only be done by adding the arg passed to npm run main at the END of the line "npm run script1 && npm run script2". I could find no way to pass it to the 1st element : npm run script1
Here is the work around I found :
1st you need to add in package.json:
"config": {
"arg1": "ARG_VALUE"
},
Then in your script you can add it to the call like this :
"main": "npm run script_no_arg1 && npm run scrip1 -- --%npm_package_config_arg1% && npm run script2 -- --%npm_package_config_component% && npm run script_no_arg2"
Finally, You don't need to call it with any arg : npm run main
But you need to modify ARG_VALUE before launc the script :)
Last thing : in my case I was calling gulp tasks :
"cleardown": "rimraf build lib",
"inline-build-templates": "gulp inline-build-templates",
"step1": "npm run cleardown && npm run inline-build-templates -- --%npm_package_config_arg1%",
It works you can get the argument into the gulp task that way :
gulp.task('inline-build-templates', function() {
let component = process.argv[3];
component = component.split('--')[1];
console.log('RUNNING GULP TASK : inline-build-templates for component ' + component);
// whatever task gulp
});
Hope it helps.
This command: "start": "node server/server.js" starts my server, but before running this I also want a command to run automatically:
'webpack'.
I want to build a script that can be run with
npm run someCommand - it should first run webpack in the terminal, followed by node server/server.js.
(I know how configure this with gulp, but I don't want to use it)
If I understood you correctly, you want firstly run webpack and after compile run nodejs. Maybe try this:
"start": "webpack && node server/server.js"
The following should work:
"start": "webpack && node server/server.js"
Though, for readability (and especially if you plan on adding additional tasks in the future), you may want to consider creating separate entries for each task and then calling each of those from start. Something like:
{
"init-assets": "webpack",
"init-server": "node server/server.js",
"start": "npm run init-assets && npm run init-server"
}
Better understand the && operator
In my case the && didn't work well because one of my commands sometimes exited with non zero exit code (error) and the && chaining operator works only if the previous command succeeds.
The main chaining operators behave like this:
&& runs the next command only if the first succeeds (AND)
|| runs the next command only if the first fails (OR)
So if you want the second command to run whatever the first has outputted the best way is to do something like (command1 && command2) || command 2
Others OS specific chaining operators
Other separators are different in a Unix (linux, macos) and windows environnement
; UNIX run the second command whatever the first has outputted
; WIN separate command arguments
& UNIX run first command in the background parallel to the second one
& WIN run the second command whatever the first has outputted
All chaining operators for windows here
and for unix here
You can also chain commands like this:
"scripts": {
"clean": "npm cache clean --force",
"clean:complete": "npm run clean && npm uninstall -g #angular/cli && rmdir /Q /S node_modules",
"clean:complete:install": "npm run clean:complete && npm i -g #angular/cli && npm i && npm install --save-dev #angular/cli#latest"
}
Also, along with the accepted answer and #pdoherty926's answer, in case you want to have run two command prompts, you can add "start" before each command:
{
"init-assets": "webpack",
"init-server": "node server/server.js",
"start": "start npm run init-assets && start npm run init-server"
}
I have multiple scripts in package.json, most of them call some .js e.g. "copyResources" bellow. If I will run "npm run -s copyResources" in shell, it will execute silently. So far so good. But I would like to run "npm start" which will execute copyResource silently, example bellow, but this is not working (it's not silent). :(
Later I will have more scripts in "start" and I want to run some of them silently and some of them not. Thats the case why I can't just do npm start -s ...
"scripts": {
"copyResources": "echo 'Copy resources =>' && node ./bin/copyResources.js",
"start": "npm run -s copyResources"
}
Thank you very much!
