Tips for uploading information and posting it on a different page with mongoDB and Node.js

I am looking to implement a feature on a website where data is submitted to MongoDB from one page, and then retrieved and displayed on another page. The technologies I am working with include node.js, express, Mongoose, and MongoDB.

Currently, the data is successfully submitted to the database and appears correctly in the layout, but I am struggling to display it on the page itself.

Could someone please provide me with an example code snippet for achieving this functionality?

This is all quite new to me, and I am still in the process of learning. Any help would be greatly appreciated! Thanks!

To load the desired page, utilize the Mongoose method .find(). When using the find() method, you have the option to retrieve all data by passing in {}, or target specific data based on the object key with find({id:'value'}). When rendering the page, simply pass an object to the render function, using the key that corresponds to the data accessed in the URL page. For instance, in this case, one would use (mongs) to access values within the URL page (.ejs, etc). In your route definition file:

app.get('/', (req, res) => {
    MongModel.find({}, (err, foundMongModel) => {
        err ? console.log(err) : res.render('url/route', { mongs: foundMongModel });
    });
});

If utilizing a .ejs file, employ <%= %> to access individual data and <% %> for loops or other operations. Make use of the mongs value. If importing all data from the database, it is possible to iterate through it using

<% mongs.forEach(mong =>{ %>
        <div>mong.key<div>
<% }) %>

Similar to the loop mentioned above, the keys for each database object can be accessed using mong.key
