I am having issue with app.get("/posts/:postName",function(req, res){ and const storedTitle =req.body.postTitle;
The issue is whenever I run http://localhost:3000/posts/Test in browser I am suppose to get output as match found but when I console log storedTitle to debug I get it as undefined istead of Test.

These are pictures of /compose ejs file.

Instead of const storedTitle =req.body.postTitle; you should use const storedTitle = post.title;
You get undefined in log because, of the following lines:
const storedTitle =req.body.postTitle;
console.log(storedTitle);
Because, GET requests does not have body.
Change those lines as follows:
const storedTitle = post.title;
console.log(storedTitle);
I suppose it is a copy/paste error from /compose handler :-)
Good day!
You cannot use req.body in a GET request
It should either use POST
app.post("/posts/:postName",....
or
const storedTitle =req.query.postTitle;
