Answer 1

Please recheck your closing bracket

your api with endpoint articles isn't closed.

 app.post("/articles", function (req, res) {
    const newArticle = Article({
        title: req.body.title,
        content: req.body.content
    });
    newArticle.save(function (err) {
        if (!err) {
            res.send("succes")
        } else {
            res.send(err)
        }
    });
});

Answer 2

A SyntaxError: Unexpected end of input error typically means either you are missing a closing parenthesis, brace, bracket, or similar character somewhere in your code or you are trying to JSON.parse() a string that is missing such characters.

Run your code/JSON string through a javascript linter (eg jshint) to find syntax errors.
