Run nodejs server

Installing the node-modules

This server needs npm and Node.js installed. You can find the installation guides here Clone or download and extract the project and go to the main project directory. Then install the dependencies by typing in

npm install

Setting the ssl connection

Our server runs on https. To use it, you should first generate the certificates. Run the following commands in the main project directory.

cd scripts
openssl genrsa -out key.pem
openssl req -new -key key.pem -out csr.pem
openssl x509 -req -days 9999 -in csr.pem -signkey key.pem -out cert.pem
rm csr.pem

In order to run the server, go to command line and change directory:

cd scripts

And type:

node server.js 

You can change the server parameters in a config file. See the "Configuration file" section below.

Run python server

Installing dependencies (Python 2.7)

cd python
pip2 install -r requirements.txt

You should generate yet another certificate. Run the command

cd python
openssl req -new -x509 -keyout server.pem -out server.pem -days 365 -nodes

Running the server

cd python
python2 simpleserver.py

Nodejs and python servers in one command

In order to run servers type:

./runServers.sh

In order to stop (kill) both servers type:

./killervers.sh

Run client application

In order to run client application, go to web browser and type:

https://0.0.0.0:8080/index.html

where '0.0.0.0' is server's host and '8080' is the port server is listening on (both configurated in the config file)

Configuration file

There are several parameters that can be set using the config file:

• main server IP address
• main server port
• python server port
• msgHistoryMaxSize - sets the maximum number of text messages sent to each new participant as a chat history
• imgHistoryMaxSize - sets the maximum number of images sent to each new participant as an image history
• colors - an array that sets the color codes used as chat colors for new users. When there are more participants than available colors, each next one gets a default, black color.
• pathForSavedImages - sets the path to the directory, where images are saved by server.
