I would recommend using create-react-app to build this project. Run the command, cd into the directory then start the app.
npx create-react-app name_of_app
cd name_of_app
npm start
This will be good enough for development, and you can add all your components into the src/ folder. Here's the documentation for how to start building react web apps.
To get the production build (which I think is what you're trying to go for), run npm run build which will save the build in the build/ folder.
Any time you use a different machine, just pull the project from github and run npm i. I'm assuming that you were talking about the package.json file. This shouldn't be a big deal if you set everything up correctly.

I am trying to install the "moralis-admin-cli" program to make my account and I have to add it the path that the Terminal gave me so it will download in the proper directory.
I did have a problem where the cursor was but that has been overcome.
So when I type in the code as the tutorial tells this how the tutorial shows how to do it and this is the error:
C:\metadata-static-app>npm install -g moralis-admin-cli
'npm' is not recognized as an internal command, operable program or batch file.
I just need to find a way to install this moralis program in the "metadata-static-app" directory on my computer so I can move on to the next step.
Can you help me.
Add node.js on your environment, the npm command will work!
I am trying to install sass and I don't understand why I keep running into the issue shown below
I understand I should follow the instructions and run npm audit fix but when I run the command, I get an error of no package.json found, and yes, that is so because sass wasn't installed at all and thus no node-modules and the json file, how do I fix this issue?
Try running the npm init command at the root of your project to generate the package.json file and re run the command to install sass.
I'm having no luck installing https://github.com/MadimetjaShika/vuetify-google-autocomplete library using npm. I'm new to using vue, and I'd like to install the prerelease developers build, 2.0.0-Alpha.9, as the old one doesn't work with my version of vuetify.
I've downloaded and extracted the zip file and then used npm install (filepath of the downloaded folder), however when i run the project I get a 'can't find module 'vuetify-google-autocomplete' error. I've only installed packages directly via npm before so I'm not sure what I'm doing wrong.
You can install a specific version of a npm module by using npm tags
npm i vuetify-google-autocomplete#2.0.0-Alpha.9
You are unable to run it because what you downloaded is an npm repo by itself.
Go to the source folder , run the command npm install , then npm run build, copy the dist folder output to your project. How include that as a module and try.
I am trying angularjs-2 for the first time from the example found here
and everything was working fine until I came to a point where the author has written something like this
Now open the package.json file location in command prompt and execute
the below command to load the required modules and supported files
which are mentioned in the package.json file.
npm start
after reading this I open command prompt by pressing window+R and write cmd
and I enter the following path
E:....\nodejs with angular2 testing\nodejs with
angularjs2\nodejs with angularjs2\
but i am not able to do anything after this point
how can i execute the package from command prompt,?
i tried the same with developer command promt but facing the same issue,
hey guys i know i am bad in english but please i need help here
First you need to have nodejs in your system.
If you don't have nodejs, then download it. which shifts npm with it. [It is similar kind of stuff what nuget does in VisualStudio.]
As you mentioned package.json is already there in your project then you need to got to you Application folder in command prompt to install packages by running npm install.
For example : If your App folder is in E:\Project\Myangular2App,
then after opening Command Prompt with window+R, navigate to E drive by E:, then navigate to your App folder by cd Project\Myangular2App and run npm install. This will install all the packages mentioned in package.json
start seems to be a script configured in your package.json which probably runs something else.
Please state if npm (the node package manager) runs on your CLI without any argument. If not you have to get npm working first. It has to be in your $PATH variable in order to function anywhere.
I'v made a static single page site using grunt. I'm now trying to deploy it to heroku using the heroku-buildpack-nodejs-grunt for node grunt.
Below is a pic of my root directory:
Here's my Gruntfile package.json:
Procfile:
web: node index.html
When I run $ git push heroku master it gets to the Gruntfile and fails:
-----> Found Gruntfile, running grunt heroku:production task
>> Local Npm module "grunt-contrib-uglify" not found. Is it installed?
The above errors proceed to list all local NPM modules as not found. If I list all loadNpmTasks instead of using "load-grunt-tasks", I get the exact same error.
When I $ heroku logs I get:
Starting process with command `node web.js`
Error: Cannot find module '/app/web.js'
Can anyone see where I've gone wrong?
For anyone passing by here, I wasn't able to solve the problem. This is where I got to:
In my Gruntfile, I moved npm modules from devDependencies to dependencies. Heroku was then able to install these dependencies.
However, when Heroku ran the tasks, it stops at the haml task w/ error "You need to have Ruby and Haml installed and in your PATH for this task to work". Adding ruby & haml to the Gruntfile as engines did not work.
The only thing I can think of is that maybe Heroku installs your devDependencies first, tries to run Grunt, but since it didn't install load-grunt-tasks yet, you don't get the grunt.loadNpmTasks( 'grunt-contrib-uglify' ); line (which load-grunt-tasks does for you), and thus Grunt can't find the package.
Can you try changing your Gruntfile to explicitly list out all npm modules using the grunt.loadNpmTasks() method?
EDIT:
Just remembered another thing I had to do:
heroku labs:enable user-env-compile -a myapp
heroku config:set NODE_ENV=production
(Obviously replacing myapp with your Heroku app name.)
This makes Heroku allow user set environment variables and then sets your server to production. Try that, and set your dependencies and devDependencies as you had them originally (just to see if it works).
I am coming pretty late to the game here but I have used a couple methods and thought I would share.
Option 1: Get Heroku to Build
This is not my favorite method because it can take a long time but here it is anyway.
Heroku runs npm install --production when it receives your pushed changes. This only installs the production dependencies.
You don't have to change your environment variables to install your dev dependencies. npm install has a --dev switch to allow you to do that.
npm install --dev
Heroku provides an article on how you can customize your build. Essentially, you can run the above command as a postinstall script in your package.json.
"scripts": {
"start": "node index.js",
"postinstall": "npm install --dev && grunt build"
}
I think this is cleaner than putting dev dependencies in my production section or changing the environment variables back and forth to get my dependencies to build.
Also, I don't use a Procfile. Heroku can run your application by calling npm start (at least it can now almost two years after the OP). So as long as you provide that script (as seen above) Heroku should be able to start your app.
As far as your ruby dependency, I haven't attempted to install a ruby gem in my node apps on Heroku but this SO answer suggests that you use multi buildpack.
Option 2: Deploy Your Dependencies
Some argue that having Heroku build your application is bad form. They suggest that you should push up all of your dependencies. If you are like me and hate the idea of checking in your node_modules directory then you could create a new branch where you force add the node_modules directory and then deploy that branch. In git this looks like:
git checkout -b deploy
git add -f node_modules/
git commit -m "heroku deploy"
git push heroku --force deploy:master
git checkout master
git branch -D deploy
You could obviously make this into a script so that you don't have to type that every time.
Option 3: Do It All Yourself
This is my new favorite way to deploy. Heroku has added support for slug deploys. The previous link is a good read and I highly recommend it. I do this in my automated build from Travis-CI. I have some custom scripts to tar my app and push the slug to Heroku and its fast.
I faced a similar problem with Heroku not installing all of my dependencies, while I had no issue locally. I fixed it by running
heroku config:set USE_NPM_INSTALL=true
into the path, where I deployed my project from. This instructs Heroku to install your dependencies using npm install instead of npm ci, which is the default! From Heroku dev center:
"Heroku uses the lockfiles, either the package-lock.json or yarn.lock, to install the expected dependency tree, so be sure to check those files into git to ensure the same dependency versions across environments. If you are using npm, Heroku will use npm ci to set up the build environment."
