CS411 Project 2 - Instant Messaging App

Project Structure:

This project is implemented with Express.js and PostgreSQL. There is no need for a front-end framework since the program changes the DOM elements dynamically.

Preparation

Make sure you have npm and postgres is installed in your machine. The project uses a single table named "messages". Therefore, you need to create a database and a table "messages" inside it.

CREATE TABLE messages ( ID SERIAL PRIMARY KEY, group_name VARCHAR(30), channel VARCHAR(30), username VARCHAR(30), time VARCHAR(8), text VARCHAR(160) );

Running the code

• Go to the project directory after cloning.
• Then, open a terminal and run the command "nodemon run dev".
• Then, open a browser and go to "localhost:3000".
• If you want to test the instant messaging feature, you can open another browser (not a tab) and go to "localhost:3000".
• Check the data.js file for user credentials that you can use to login. Ex: (username: arda, password: ardapw && username: elif, password: elifpw)
• You can select group and channel and start to chat. After leaving and rejoining the same group or channel, message history will be available.
