Running angular 2 demo app using only node js [on hold] - node.js

I am new to angular 2 and node js environment, can anyone help me in just how to run angular app using node js without any connection to DB, step by step will be helpful.

make a build of your angular app using the following command
ng build --prod --build-optimizer
then you get the dist folder rename it to public
in your node-express project directory paste the public folder & add the following piece of code in your app.js file
app.use(express.static(path.join(__dirname, 'public')));
app.get('*',function (req,res) {

First you have to install node.js and npm and Verify that you are running at least node 6.9.x and npm 3.x.x by running node -v and npm -v in a terminal/console window. Older versions produce errors, but newer versions are fine.
After that install Angular CLI using below command
npm install -g #angular/cli
Then for create New Project use below command
ng new my-app (here my-app is your project name)
Last step move to your project location using below command
cd my-app (here projectLocation/my-app is your project path)
then type ng serve --open
it works
Enjoy... for more reference


Error showing while creating new project in Angular

Why this error showing while trying to serve(run) a new project in AngularJs ?
Node is installed.
Angular CLI is installed.
A new project is created.
I guess you are missing something here .
If you are using cli you need to first install cli using npm install -g #angular/cli and then
ng serve
If you are just forking a angular library please check if any package,json file is there in the root or any level if it is there navigate to that folder and then do a npm install

'electron-packager' is not recognized as an internal or external command

I recently started using electron. I have successfully completed the 1st phase by creating a hello world app (included files index.html, main.js, package.json). Now I am trying to package the app using electron-packager but getting this error
Steps I have followed:
Created a project directory named helloworld.
Initialized the project directory using npm init command.
Then installed electron using npm install electron --save-dev.
Then created the javascript and html files as main.js and index.html respectively.
Then used npm start to execute the application.
Then installed electron-packager using npm install electron-packager.
Now the problem is coming in this step when i am trying to pacakge the app using command electron-packager .
npm install -g electron-packager
You need the -g flag to install it globally which makes the command electron-packager available in your PATH.
If you do not do a global install, you will need to run ./node_modules/electron-packager/cli.js instead.

Angular 2 - building “dist” for production using “npm”, and not “ng build -prod”

I have a project that I am building and running with npm start instead of ng serve. I am an angular 2 beginner, so I don't know how to build this project for production, in order to have the dist/ folder with pure javascript/html/css in it. For ng init - created angular 2 apps, if I use ng command, I can just do ng build --prod when work is done and the dist folder is created. If I use ng build --prod on this project, angular is offering me to overwrite some of my files (app.module.ts, app.component.ts, etc....) which I don't want overwritten. There are routing things inside and I don't want to change them. How can I have the production version of this app (ie. the dist/ folder) without using the ng build --prod command? Angular-cli version is:
angular-cli: 1.0.0-beta.28.3
I think you should use #angular/cli instead of angular-cli :
npm install -g #angular/cli
when I use ng build --prod there is no such a problem.
Please follow these instructions to update your CLI to the latest version:

getting “ENOTEMPTY: directory not empty, rmdir …” error on installing express in angular CLI app.

I am creating my first MEAN app. I have installed angular CLI and also tested it using ng serve -o this command then i build app using ng build which also succeeded.
Now when I am trying to install "express" and "body-parser" I am getting following error
ENOTEMPTY: directory not empty, rmdir '/media/iconflux/DATA/vinit/Mean/meanApp/node_modules/fsevents/node_modules/dashdash/node_modules/assert-plus'
I checked the directory it is empty. I also tried manually deleting the directory but still no success.
Here is the command i am using to install express and body-parser
npm install --save express body-parser
Note: I am working on ubuntu 14.0
Any help will be appreciated Thanks.
use this command : npm install --save express body-parser --force
