Goal: You should be able to go to the compose page and add a new post which will be added to your database as a new document.
Verify by going into the mongo shell and find all posts.
Scroll down for a hint 👇
You need to install mongoose and require it in your app.js
You’ll need to connect to a new database called blogDB
mongoose.connect("mongodb://localhost:27017/blogDB", {useNewUrlParser: true});
You’ll need to create a new postSchema that contains a title and content.
const postSchema = {
 title: String,
 content: String
};
You’ll need to create a new mongoose model using the schema to define your posts collection.
const Post = mongoose.model("Post", postSchema);
Inside the app.post() method for your /compose route, you’ll need to create a new post document using your mongoose model.
 const post = new Post ({
   title: req.body.postTitle,
   content: req.body.postBody
 });
You’ll need to save the document to your database instead of pushing to the posts array.
post.save()
