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