Project created by Massimiliano Bellia and Claudia Luisa Crippa for the web programming course at the University of Milan 'La Statale'.

The project is a webchat coded in Javascript following the MVC pattern. It has a registration and login system, created with passport and PostgreSQL. The database stores the users for the login system, the messages sent and the rooms created by the users. The input is sanitized using DOMpurify in the backend.

Requirements:

express
	npm install express --save
PostgreSQL
PgAdmin 4
	 npm install pg
passport
	npm install passport --save
passport-local
	npm install passport --save
bcryptjs
	npm install bcryptjs --save
express-session
	npm install express-session --save
dompurify
	npm install dompurify --save
jsdom
	npm install jsdom --save

Table creation queries:

-- Table: public.users

-- DROP TABLE public.users;

CREATE TABLE public.users ( id bigint NOT NULL DEFAULT nextval('users_id_seq'::regclass), username character varying(255), password character varying(100), room text, CONSTRAINT users_pkey PRIMARY KEY (id), CONSTRAINT users_username_key UNIQUE (username) ) WITH ( OIDS=FALSE );

-- Table: public.rooms

-- DROP TABLE public.rooms;

CREATE TABLE public.rooms ( name text NOT NULL, id integer NOT NULL DEFAULT nextval('rooms_id_room_seq'::regclass) ) WITH ( OIDS=FALSE );

-- Table: public.messages

-- DROP TABLE public.messages;

CREATE TABLE public.messages ( id integer NOT NULL DEFAULT nextval('messages_id_seq'::regclass), value text NOT NULL, room text NOT NULL, "time" text NOT NULL, username text, CONSTRAINT messages_pkey PRIMARY KEY (id) ) WITH ( OIDS=FALSE );
