I have been planning to start working on a new application for my current college project. What I would like to do is create an electron app that will start specific tasks based on a gulpfile.js.
This is mostly to let people start the gulp tasks even if they aren't used to work with the terminal .
Now the question is: If I package the application (macOS) and the final user don't have any node/gulp.js installed globally, will this work? Is it possible to package an electron app with gulp and fire some gulp taks anyway?
I don't have enough time to start the project without knowing if it will work, that's why I'm addressing this to you guys, I need your help in the subject :)
I have also searched on Google for some solutions, but I didn't find any.
Thank you!
I don't know about gulp in particular, but as it seems to be an npm module, you'll be able to install it locally with your electron app. In the terminal cd to your electron/resources/app folder and run
npm install gulp-cli -g
npm install gulp -D
(as shown on https://gulpjs.com/)
You then should see a node_modules folder in the same directory, which contains the install of gulp. This can then be packaged in the same way as any other electron app.

I want to run this app on my windows,
the directions say:
-Install dependencies with npm update
-Start the application with node app.js
it's sound easy so I try myself.
1.Fist of all , I install node.js on it's official website (https://nodejs.org/en/)
I　download the 8.9.3 version.
after installing node.js
2.open the command line and go to the project path.
3.then I input the command npm update.
it works,and the node_modules folder is created.But there are some warn message
4.finally input the command node app.js... it's not work with many error message
following is wrong message
I wonder know how should I do.Is any thing I didn't installed?
Please help me.I really want to research this mahjong project.
Before running npm update in the directory where you have your project, you should run npm install first to install all the required dependencies needed for the project to run.
So I advice to delete the node_modules directory that was created after you ran npm update, after which you can then run npm install. This should solve your issue.
Update: If you just want to try it online and not run it locally they've hosted a version on the web: http://gleitzman.com/apps/mahjong.
It's not your fault.
What you did was correct, but the project documentation needs to be updated. It's not a turn-key solution and you'll need to figure a few things out to get it working.
The error message is says it wants a mongo db instance, but you don't have one running. Try the mongodb home page or google for instructions. If you have docker it is pretty easy: docker run -it -p 27017:27017 mongo.
Even after spinning up mongodb I wasn't able to get the app to work locally. You could try contacting the repo maintainer for assistance. They may be happy to help given you've shown interest in their project.
Good Luck!
I an having some little problem's when trying to command my project to run with the 'ionic serve', command, inside of the application folder. Every time that i use this command the cmd return the message 'Starting server - done!' and don't run my program.
I already tried to uninstall and reinstall my Cordova, npm and Node.js, at least five times, in each time using a different version of Node.js but without success. I tried to use gulp command in the last installation before the 'ionic serve' command, without success again.
This project of Ionic was downloaded in TFS, because my colleage create him im my enterprise and update to TFS, then i downloaded it.
Now my Node JS has the version 6.10.1 and my npm is in the version 3.10.10. I have a project to deliver in one week and are desperate to solve that.
I will be grateful for any help. Thank you everyone.
Delete the node_modules folder from your project.
Run the command npm install (It will recreate a fresh node_modules folder).
Then run ionic serve.
My friend, i solved in another way.
The person of my enterprise, who had uploaded the project don't put the node-modules folder. Than i copy the folder of him and put in my project, after i used 'ionic serve' command and everything just worked well.
Thank you for your help. I am very grateful.
I want to build a small js plugin, and I want to try that with ReactJS.
ReactJS recommends installing using npm and browserify.
In my experience with Ruby on Rails, there are always a lot of things to install, and using Windows introduces additional problems.
With Ruby it is Rails Installer. What is JS equivalent of Rails Installer? i.e. a tool that lets me install all necessary packages with one step?
I did a little bit of search, find that I need to install:
NodeJS, NPM
NVM
Webpack or Browerify
Babel
I think there may be others that I need.
To start the project you need node and npm because webpack, browserify and babel is npm packages.
The only way to install all packages in one step is to install package that actually depend on all packages you need. There is a lot of ReactJS starter kits in github like this https://github.com/kriasoft/react-starter-kit
I, personally recommend you doing such a things by yourself - its not a big deal if you understand what you want. In the root of all nodejs projects there is a file package.json every time you need a new module (package) just type npm install -S <module_name> in the root directory of your project.
This new module appears in node_modules directory and because of -S flag it name also will be stored in dependencies of your project in package.json file so that in the future you can just type npm install to install all dependencies (aka modules/packages) of your project.
Is it ok to have a node.js project with no package.json? The ones I see on the internet all come with package.json
What is the effect of having no package.json?
How is package.json created in the first place? Is it created automatically? I am wondering why I do not have package.json
Fundamentally, package.json is a meta file for your application. It lists all the configuration of your application.
What is the effect of having no package.json?
Nothing as far as you're running all your code locally and have no requirement for deployment whatsoever.
Let's setup a scene for you to understand this better.
Imagine that you wrote a brilliant application using node. Now all the chicks in your surrounding want it to play with. It is so fantastic!
Now you want to give it to them and during the development process you `npm install`ed so many things that your project grows beyond 4TB size.
There is no data storage device available to ship that huge code base.
Then the girl of your dream said I want it and I want it now. So you begin searching for app deployment process for node applications.
That is where you stumble upon a magical thing called package.json.
So what you do is you list all your npm installed modules under dependencies property. Then you delete node_modulesfolder, add package.json and commit the entire damn thing in github. Even the .zip file is of 10MB
Then she gets the code.
Types in npm install && npm start (which will install all the dependencies from the package.json` and start your application)
If you have package.json however, that is where you specify all your dependencies.
Using --save flag of npm install
Example.
npm install express --save
How is package.json created in the first place? Is it created automatically?
You can manually create a text file and save it as package.json
OR
A more sophisticated way is to use the command
npm init
I am wondering why I do not have package.json
Me too! :)
You're most probably following a tutorial that doesn't emphasize on initial configuration of the project OR the author of those tutorials presume that the reader has all the fundamentals down to begin with.
It is created automatically if you write npm init.
Then, every package you add using npm install packagename --save will be added to the dependencies list.
You need package.json so that when you want to use your project on another machine you don't have to copy all node_modules, but only your .js files you have written, assets and package.json. You can then run npm install command and it will automatically download and install all the required modules (found in the list of dependencies inside package.json).
You can also manually create or edit it, but it's easier to add --save when installing a module so you don't have to worry about package versions and stuff like that.
Also if you want to create a npm package, an open source project or stuff other people will use, it's either required or the norm to have this package.json file describing your project.
package.json is npm file, if you don't use npm you will not have this file, npm is a great tool if you want to use external libraries in your project but if you don't need it (which is very not likely unless you are doing something very simple), you don't need package.json file too.
To generate package.json file initialize npm in your project using npm init
possible reason thus it exist is you maybe you enter a wrong command like npm i -y, you must initialize the project first, just enter a command npm init -y
Welcome.
Well, if you are running it on your local machine, it's fine. now to answer your last question, package.json is not created automatically.
the npm command npm init -y creates the 'package.json' file. It basically makes sharing your code and installing your codebase easier.
Before I say anything else, I am a complete noob to node.js and I just want to see what this web application looks like. I noticed this project at a hackathon and I wanted to test it out. They gave the github repo: https://github.com/android-fanatic/Web But I can't run it from my computer. I understand that I would need to use the command prompt and run it from my local server, but can someone give me step by step directions for installing the node.js app?
Again the link is:
https://github.com/android-fanatic/Web
Thanks in advance for any help! :)
Install Node.js
Clone the repository to somewhere on your hard drive
Open a command prompt and go to that directory
Type npm install to install any dependencies
Type npm start
???
PROFIT
The reason you can use npm start is because if you look inside of their package.json file you'll see a "start" option under "scripts". That command will execute when you type npm start.
Assuming you have node and npm installed on your system, you should be able to do:
npm install
npm start
The first command will install the node package dependencies and the second will run the server.
Note: I have never used this project, so my guess is based on looking at the repo alone.
The web application should be available at:
http://localhost:3000
