I have a node app that I just started working with and each time I try to run it, it says there is a missing module. I've just been using npm install ... for each module but after doing about 10 of them I'm wondering if there is a way to have npm pull down all needed modules for a node app without me installing each one manually. Can it be done?
Yes, as long as the dependency is listed in package.json.
In the directory that contains package.json, just type:
npm install
I created an npm module to handle installing missing modules automatically.
It will install all app dependencies and sub-dependencies automatically. This is useful when submodules aren't installed correctly.
You can run npm install yourModule --save in order to install and automatically update package.json with this newly installed module.
So when you run npm install a second time it will install every dependecy previously added and you won't need to reinstall every dependency one by one.
I writed a script for that. Please add it before the first require function:
(function(){
var r=require;
require=function (n){
try{
return r(n)
}
catch(e){
r('child_process').exec('npm i ' + n,function (err,body){
try{
console.log('Module "' +n + '"" not found, try to install. Please restart the app\n' + body )
return r(n);
}
catch(e){
}
})
}
}
})()
