NodeJS kit crashes on startup due to deprecated bodyParser() usage and missing dependencies

[amanjagdev]

Description

The NodeJS integration kit in its current state fails to start on modern Node.js environments due to two critical issues:

1. Deprecated bodyParser() call crashes the server

In main.js, the middleware is initialized as:

app.use(bodyParser());

This form was removed in body-parser v2+ and deprecated long before that. It throws a TypeError: bodyParser is not a function or similar error, preventing the server from starting.

Fix: Replace with the explicit middleware calls:

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

2. Missing dependencies in package.json

express and body-parser are required in main.js but were never listed in package.json. Running npm install from a clean clone does not install them, causing require() to fail.

3. No .gitignore

node_modules/ and .env (which contains secrets like EASEBUZZ_KEY and EASEBUZZ_SALT) have no .gitignore entry, risking accidental commit of sensitive data and bloating the repo.

Steps to Reproduce

1. Clone the repo
2. cd Easebuzz_NodeJS_kit && npm install
3. node main.js
4. Server crashes immediately

Expected Behavior

Server starts and listens on port 3000.
