Answer 1

In articles.js you have return the function after displaying title cause the problem!
// Register of article
router.post('/new-article', (req, res, next) => {
let article = new Article();
article.title = req.body.title;
console.log(req.body.title);
// return;
article.save(function (err) {
if (err) {
res.json({
success: false,
msg: 'Failed to Register the Article'
});
} else {
res.json({
success: true,
msg: 'New Article is Registered'
});
}
});
});
