How can I add blog outputs in main page?

Question

I'm currently creating my own blog website. Everything was great, but then I realised that I've been stuck on adding the output of blog title and content to my main page using ejs. Here is my code; What have I done wrong or what do I need to do? I want to add the user input to main page but when I try I got the error message about defining the values.

app.js:

//jshint esversion:6

const express = require("express");
const bodyParser = require("body-parser");
const ejs = require("ejs");

const homeStartingContent = "Lacus vel facilisis volutpat est velit egestas dui id ornare. Semper auctor neque vitae tempus quam. Sit amet cursus sit amet dictum sit amet justo.

const contactContent = "Scelerisque eleifend donec pretium vulputate sapien. Rhoncus urna neque viverra justo nec ultrices. Arcu dui vivamus arcu felis bibendum.

const app = express();
let posts = [];

app.set('view engine', 'ejs');

app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(express.static("public"));

app.get("/", function(req, res) {
  res.render("home", {
    startingContent: homeStartingContent
  });
})

app.get("/about", function(req, res) {
  res.render("about", {
    about: aboutContent
  });
})


app.get("/contact", function(req, res) {
  res.render("contact", {
    contact: contactContent
  });
})


app.get("/compose", function (req, res) {
  res.render("compose", {
    title: req.body.postTitle,
    content: req.body.postBody
  });
})

app.post("/compose", function (req, res) {
  const post = {
    title: req.body.postTitle,
    content: req.body.postBody
  }
  posts.push(post);
  res.redirect("/");
})



app.listen(3000, function() {
  console.log("Server started on port 3000");
});

home.ejs:

<%- include("partials/header") -%>

<h1>Home</h1>
<p> <%= startingContent %> </p>

<h1><%= title %></h1>
<p><%= content %></p>

<%- include("partials/footer") -%>

  <h1><%= post.title %></h1>
