Node.js and Express.js can be used to save data to the Mongoose database. The MEAN stack, which stands for MongoDB, Express.js, Angular.js, and Node.js, includes MongoDB, Express.js, Angular.js, and Node.js. In this tutorial, I'll demonstrate how to use Express.js, Node.js, and MongoDB.js. We'll create a very simple MongoDB data entry Node application that enables user input. Additionally, it will show every object that has been added to the database. Before we get started, we'll define a few terms that you'll hear a lot when designing a MEAN stack development. We'll then start building our example after that.
CRUD, or Create, Read, Update, and Delete, is an acronym. The process of getting your data saved in a database is referred to by this phrase. In this example, you will show how to read data from the database after inserting new data into it.
An application programming interface known as a RESTful API enables you to GET, PUT, POST, and DELETE data via HTTP queries. To manage when data is read from and added to our database, we'll use an API.
Creating a Node Application
A RESTful API is a type of application programming interface that supports HTTP GET, PUT, POST, and DELETE operations on data. We'll utilise an API to manage when data is added to and read from our database.
Saving Data to Database
A JSON object can be saved to the database using Mongoose's save function. Our body-parser middleware will translate the user's input into JSON format.
To save the data into the database, one might need to build a new instance of the model we created before. This instance will receive the user's input. Once we have it, we only need to type the command “save.”
Mongoose will deliver a promise following a database save. A promise is returned once the database save has been successfully completed. This saving will either finish successfully or it won't. A promise has two strategies for addressing these two possibilities.
The promise will recursively move back to the then section if the database saves were successful. In this case, we'd like to text the user to let them know that their information has been stored to the database.
It will go back to the promises if it fails. capture a moment. In this case, we'd like to text the user to let them know that their information wasn't saved to the database. Additionally, it is advised to modify the statusCode returned from the typical 200 to a 400. A 400 statusCode indicated that the operation had failed.
XcelTec has created a notes app that has all CRUD capability. The code might seem challenging at first, but you can only learn if you write it yourself. You will learn better by doing than by watching, and XcelTec is always available to help you achieve your objectives.

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.
To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.
Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Let me show what I mean…
There are template parser errors that can be easy catched by stackblitz

Last decade has seen introduction of lot of new software development framework and technologies. The purpose behind creating these frameworks is to serve the need of growing demand for web and mobile applications around the world.MEAN stack is one of these latest tools for web based software development.
What is Mean stack?
MEAN Stack development is basically a composition for MongoDB, Express js, angular.js and node.js. MEAN stack some time uses react.js and to form MERN stack.Let’s look at each component in more details.
Mongo DB: MongoDB is an open-source NoSQL database that will hold all of the application’s data. It allows developers to quickly change the structure of the data is persisted. Here it relies on an architecture that comprises of collection & documents and not table & rows.
Express JS: It is used to create web application easily. Also provides a slight simplification for creating a request to developer procedure. This way it gets easier to write modules, secure & fast applications.
Benefits of MEAN Stack Development
Server and Client switch was never this easy
Multipurpose and Flexible
MEAN stack is truly wonderful and offers greater flexibility with development to developers. The framework allows for easy testing of the app on the cloud platform upon completing the development process. The development, testing and introduction into the cloud processes are done seamlessly. Any additional information can also be incorporated into the app by simply adding an extra filed on to the form. The technology responsible for this feature is MongoDB which, because it is specifically tailored for the cloud, offers automatic replication and full cluster support.
Build MVP quickly
MVP stands for a minimum viable product. It comprises to the app developed with the most basic and essential features. This set of features are the bare minimum of what users are searching for in a product. Being able to develop an MVP in the shortest time possible is critical for cutting costs as well as testing the product in the market. The MEAN stack makes it possible to create an MVP quickly because the framework offers fast development.
MEAN / MERN allows Isomorphic coding possible
There are two major OS platforms on which mobile operators, namely: iOS and Android. Anyone interested in creating an app for both platforms needs to do a separate project for each. But with the MEAN / MERN stack, this is not necessary. Apps developed using MEAN /MERN are isomorphic, meaning that they can work on multiple platforms without having to change the base code. Thus, the developer’s work is cut in half and more time is spent on enhancing the app already created. Businesses aiming to reach a wider market segment will therefore benefit from using the stack.
Ease in Development with Single Programming Language
Responsive and Time-saving
If you need to develop an application with limited timelines, use MEAN stack to achieve that. It has infinite module libraries for node Js, which are ready for use. As a result this aspect saves your time and initially used to create modules from scratch. It also has an automated testing feature that instantly notifies you when a particular feature is broken. It gives you more time to polish your project to perfection.
Some of the benefits outlined above are just a little of what the company stands to gain in incorporating the MEAN stack in their app development projects. Enhanced app quality, reduced costs, and time for app development and also which to save time and money, or are just interested in managing a business.

There's a wise old saying: "Working with a full stack developer can lead to better technology solutions." And in recent years, this saying has proven to be true for many startups.
In the last few years, we have heard a lot about full-stack developers.
We know that a full-stack developer is a person who has complete knowledge of the different layers involved in application development. Whether you are dealing with the front or back end or working in the business layer, they take care of everything with ease.
But did you wonder why a full-stack developer is so important for a startup?
This blog will answer all such queries. So let's get started.
As per a development report published recently, it was seen that there had been a 206% increase in demand for full-stack developers from 2018 to 2020. This is because more companies seek multifaceted skills.
Full-stack developers or a full-stack development company are able to take care of all the development needs of your project. So whether it's front-end or back-end development or enterprise layer development, they are competent to work on everything. You can always hire full-stack developers for your business needs.
In terms of software development, there are front-end developers and back-end developers. Front-end developers create the interface, while backend developers design the software.
A full-stack developer can do everything. They take care of application design, server-side scripting, client-side coding, coding, administration, database creation, and any other project development needs.
The following are the responsibilities of a full stack developer that you hire:
Manage web development
Code applications and programs
Coordinate with other team members and developers
Think about testing techniques for web applications
Over time, the skills required for full-stack development have expanded and evolved. Long ago, the LAMP stack included Linux, Apache, MySQL, and PHP. It is more than MEAN and beyond today.
When hiring a full-stack developer, companies are always looking for candidates who are capable of solving a problem. Full-stack developers are competent to handle all aspects of the project. They prove to be a practical solution for startups that are not willing to spend more money on many developers.
The main reason companies choose full-stack developers for their projects is their potential rather than their knowledge. Over time, companies teach them the skills they want them to have. In this way, in a few years, they learn different technological skills as the company expands.
Companies like to have people with business experience on board. A full-stack developer has the knowledge and expertise to work on the front-end, backend, and media architecture layers. This means that they are capable of performing better than an individual front-end or backend developer.
As full-stack developers can develop all aspects of a project, it is not necessary to form a team of experts. They will easily handle the project without help from anyone. This will save the right amount of money for the recruiting team.
Full-stack developers know different technologies, tools, and techniques. This means that when they take the project, they will be able to complete it faster. They will spend less time discussing and collaborating with the team on the project.
Full-stack developers have enough experience to create outstanding features for the final product, which will be able to excite the market. They have the ability to build a complete product from scratch. If you want to gain some benefits from your product, you will have to collaborate with these experts. Remember that not all developers are capable of handling the project from a 360-degree perspective.
Full-stack developers take on different web projects. This has helped them gain in-depth knowledge of various technologies and the experience to find quick solutions in web and application development. Such understanding and knowledge improve the performance of the project and its reception in the market.
The main advantage of choosing a full-stack developer for your project is that they will come up with the complete structure of the project and offer their valuable input to the project as needed. Their services go beyond project development to maintain and optimize existing solutions.
Web design plays a crucial role in whether most people love or reject a website. Full-stack developers will make sure that the website is pretty user-friendly. They keep up with trends and technological innovations. To make sure their clients get the best interactive and responsive website, the developers implement intelligent features in their projects.
Full-stack developers have complete knowledge and experience of the different stages and aspects of website development. They are skilled enough to identify problems that may arise during the development of the project. They will propose long-term solutions to ensure that the website or application works optimally based on their findings.
In addition to leading your web project and enabling enhancements to it, full-stack developers move to the level of representing your product to stakeholders or your company at conferences. They can move quickly from one operation to another with ease, streamlining the development process.
If you are on a tight budget but want to create a fantastic website, then you should consider hiring full developers for the job. You can even think about having a remote full-stack developer for the project. As such, a developer is capable of handling all aspects of project development; you won't have to hire different people for the job. This will save you a lot of money.
It will be easy for developers to share responsibilities among the team and coordinate with each other for better project progress. This will result in faster delivery of the project.
When you hire full-stack developers for your project, you can be sure that they will take care of everything. Such a developer will be able to develop MVP from start to finish. If you hire a full-stack developer in the middle of the project, even then, you'll find a way to join the flow seamlessly. Such a developer will work towards quality control of the design project.
So these were the advantages of hiring a full-stack developer. I hope you have noted the changes that a full-stack developer can bring to the table and in your company. However, working with a full-stack developer is the best way to work with a top full-stack development company in India.
It is a good idea that full-stack development companies bring to your projects are phenomenal and groundbreaking due to the expertise and experience that full-stack development companies bring to your projects.
