Here is some JavaScript sample programs I've made when I study Node.js javascript programming.

##Table of Contents

1. Simple Node Server
2. Upload Picture
3. Simple Blog
4. Contact
5. Resources

This is the first Node.js based back-end javascript program I've ever made. It's very simple and can receive post request from browser and send back the contents to the end user.

This is a picture uploader base on Node.js and formidable module. To run this, you must first install the formidable package.

npm install formidable

The small application provide 3 pages: start, upload, show. start page provides a file uploader, upload page saves the file user uploaded, show page just shows the picture user uploaded just now.

Environment: (Node 0.10.33, Express 4.12.1, mongoDB 2.6.8)

Blog is a minimal blog system based on Express. Express is most famous Node.js framwork. To use this, we must first install it by the following command.

$ npm install express-generator -g
$ express -e blog (add ejs engine support)
$ cd blog && npm install
$ DEBUG=blog node ./bin/www

Then, we can check it on the browser with localhost:3000. Done the Express installing.

Installing mongoDB, type the command as follows.

$ vi /etc/yum.repos.d/mongodb.repo 

Write the following configuration (64-bit system)

	[mongodb]
	name=MongoDB Repository
	baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
	gpgcheck=0
	enabled=1

Then, install package with yum command.

	$ yum install mongo-10gen mongo-10gen-server

After this, the mongoDB is installed, then we may use $ cd /bin/ && mongod --dbpath ../blog/ to set the DB storaging directory to /blog and start mongoDB with service mongod start.
