NodeExpresEjs

Demo web app using node js, express and ejs using express-generator boiler-plate.

Node js express ejs setup

This walkthrough will give a basic idea for quick setup of nodejs application using express framework and EJS as view template. For quick design are going to use boiler plate provided by express-generator package.

Required

NodeJs and npm should be installed and running on your machine. Check the version by typing the below commands in the terminal.

node -v v6.9.1

nmp -v 3.10.8

For generating the stub we need to install express-generator.

npm install -g express-generator

If you faces permission error do sudo on the command.

sudo npm install -g express-generator

N.B. -g flag specifies you are installing the package globally.

Now we are going to create express application using express-generator boiler plate.

express -e NodeDemoExample

Usage: express [options] [dir]

Options:

-h, --help           output usage information
    --version        output the version number
-e, --ejs            add ejs engine support
    --pug            add pug engine support
    --hbs            add handlebars engine support
-H, --hogan          add hogan.js engine support
-v, --view <engine>  add view <engine> support (ejs|hbs|hjs|jade|pug|twig|vash) (defaults to jade)
-c, --css <engine>   add stylesheet <engine> support (less|stylus|compass|sass) (defaults to plain css)
    --git            add .gitignore
-f, --force          force on non-empty directory

install dependencies:

cd express_example && npm install

run the app:

DEBUG=express_example:* npm start

Normally when you are working in a nodejs application, you need to restart teh app again and again once you are submitting any changes. If you use nodemon package, it will build and re-deploy the application. No need to restart app.

npm install -g nodemon

DEBUG=express_example:* nodemon

For windows

install dependencies:

cd NodeExpressEjs && npm install

run the app:

SET DEBUG=nodeexpressejs:* & npm start SET DEBUG=nodeexpressejs:* & nodemon
