使用 mongodb 在 GET 请求中编写 .find 查询的最佳方法是什么？

Question

I am trying to make a GET request so that it only returns the last item stored in my database. I can get the answer I want in the mongo shell (see below), but I'm at a loss as to how to compose the query in my GET route. I am using ejs templates, so I will also need to pass the response through the res.render as well. I am still kind of new to programming so forgive me if this question isn't as concise as it should be.

My mongo shell query: Blog.find().sort({_id:-1}).limit(1)

I hope the code below gives you a hint on how to structure your code using express and EJS.

app.get("/", async (req, res) => {
  try {
    const blogItem = await Blog.find().sort({_id:-1}).limit(1);

    // Render the page with the result
    res.render("your-page.ejs", { blog: blogItem });
  } catch (error) {
    // Handle errors here
    res.render("500.ejs");
    throw error; 
  }
});
