    Way to create basic application in MERN Stack

    MongoDB, Express, React/Redux, and Node.js are the technologies that make up the MERN Stack. The MERN Stack is a popular JavaScript stack used to make modern, single-page web apps. This MERN stack lesson for Groovy Web shows you how to build your Stack from the bottom up, starting with React for the presentation layer, Express and Node for the middle or application layer, and MongoDB for the backend database.

    MERN Stack’s Benefits

    This MERN stack tutorial will show you how to use these four technologies to build a small app that uses React to store and show data. The information will then be shown on the program.

    How to Create MERN Stack Application:

    To start, you need to do the following:

    Configure the Node

    It would help if you had either the Long-Term Support (LTS) version or the latest stable release to install Node.

    Source Code Editor: Keep or Set One Up

    You can use any text editor you want for this tutorial. But to show anything, we will use the VS Code editor with the nicer and vs. code icons plugin.

    Start working on the MERN Stack

    By using MERN, we can come up with all-around solutions to problems. So, we’ll use the MERN Stack to make the most of what it can do. A back end and a front end will need to be made for this project. The front end will be made with React, and the back end will use MongoDB, Node, and Express. In this case, we’ll refer to the client and the server as the “frontend” and the “backend,” respectively.

    Open the file manager on your computer and create a folder called MERN. Once a new project has been started, all the files that go with it will be kept here. After that, we’ll build a client app with React Native.

    The next step is to make a folder for the backend and give it the name server.

    We’ll start making the server by going into the folder we made for it earlier. Then, we’ll use npm init to turn on package.json.

    Here are some of the words that were used in the last command:

    You can install the MongoDB database driver by running the MongoDB command, letting your Node.js apps connect to the database and do database operations.

    Express can be used to set up the Node.js web framework. (It’ll make our lives easier.)

    Cors will include a package that makes sharing resources between sites that use Node.js easier.

    Dotenv is a command for installing a module that reads the contents of an.env file and writes them to the process’s.env file. This makes it possible to store configuration files somewhere other than where the program’s source code is.

    The package.json file lets us see the dependencies that have been installed.

    The packages and the versions of each one must be shown.

    Getting in touch with MongoDB Atlas

    It’s time to connect our server to the source of data. The MongoDB Atlas database will be used.

    MongoDB Atlas is the best cloud-based database solution if you want to make sure that your data is safe and reliable.

    Using the free tier cluster that MongoDB Atlas offers, you can use some of the features and functions that MongoDB Atlas offers. This cluster can be used for as long as you want.

    The Atlas connection string can be found in the cluster’s configuration file. The Get Started with Atlas tutorial will show you how to create an account and deploy your first cluster.

    Callbacks to the API Server

    Done with the database. Exiting server. The final destination for the Server API is where we are going now. Make a new folder and name it “routes.” Then drop the record into it.js inside of it to start things up.

    Getting the ball rolling

    After you’ve added the features you want the API to have, you may create a way for the client to communicate with the API.

    To start, you will use the create-react-app command to build your app and start the front end of the to-do app. To finish this task, go to the root directory where your backend code is stored and run the following commands from the mern-todo folder:

    When you do this, a new folder called “client” will be created in your mern-todo folder. Here is where you should put the React code that you need.

    The React app must work

    Before testing the React application, several things must be in the project’s root directory.

    Nodemon is used to both control and keeps an eye on how the server works. If Nodemon sees that the server’s source code has been updated, it will restart the service using the new code.

    Come up with the React Parts

    One of the many benefits of React is that it makes it easier to reuse code and break it up into smaller pieces. Your to-do app will have two state components and one stateless component.

    Assuming that these files are saved successfully, your to-do app will be ready and fully functional. You can use the MERN stack development Company to add a task, delete a task, and see all of your tasks.

    Conclusion

    You used the MERN stack during this class to build a to-do list app. You used React to build a lightweight frontend stack that talks to an Express.js backend. You have also built a MongoDB backend, which will be used to keep track of tasks.
