How to dynamically create an array of buttons in React using MonogoDB?

by

Im trying to convert my static product configurator into a dynamic one using the MERN stack, and I am really close to being done with the test version finally! I have everything working, but I am having trouble making it even more dynamic. In my configurator here for example, I have the ability to change colors through a list of hard coded buttons that trigger an event. This gets tedious with the amount of products that I will be trying to deploy to our website, and some products are only available in one, two, or three materials. I have successfully uploaded an array to MongoDB and is structured like so: How to dynamically create an array of buttons in React using MonogoDB?How to dynamically create an array of buttons in React using MonogoDB?How to dynamically create an array of buttons in React using MonogoDB?

How can I save checkbox state to my database?

by

I’m trying to create a Todo-list app using (nodejs,ejs…) so for every todo I create a checkbox. If someone finishes his job and uses the button bin recycle to delete it, I save that using MongoDB but I’ve a problem when checking. When I reload the page this checked box disappears. In other words, my question is: How to save the information in my database if the checkbox is checked?

When to use MongoDB or other document oriented database systems?

MongoDB is not a key/value store, it’s quite a bit more. It’s definitely not a RDBMS either. I haven’t used MongoDB in production, but I have used it a little building a test app and it is a very cool piece of kit. It seems to be very performant and either has, or will have soon, fault tolerance and auto-sharding (aka it will scale). I think Mongo might be the closest thing to a RDBMS replacement that I’ve seen so far. It won’t work for all data sets and access patterns, but it’s built for your typical CRUD stuff. Storing what is essentially a huge hash, and being able to select on any of those keys, is what most people use a relational database for. If your DB is 3NF and you don’t do any joins (you’re just selecting a bunch of tables and putting all the objects together, AKA what most people do in a web app), MongoDB would probably kick ass for you.
