Are you looking for some CRUD app ideas? We’ve got you covered! In this article, we will talk all about CRUD apps and how you can develop them on your own.
CRUD stands for CREATE, READ, UPDATE, and DELETE operations. You may have encountered different apps that perform these four basic crud operations. Isn’t it fascinating to know that you can create such apps on your own as well?
Well, we are going to discuss some ideas that you can work on to build these apps. So, let’s dive in!
Summary Of The Article:
CRUD is an acronym for CREATE, READ, UPDATE, and DELETE.
These are the basic operations that are performed by almost all web applications and software aimed at solving user problems.
We can easily store, manage, and retrieve the data using these operations.
CRUD functionality makes our applications scalable and provides secure access to databases, hence, providing security and effectiveness.
What Are Some Of The Development Tools For Building CRUD Apps?
To build a CRUD application, there are a variety of development tools and services that one can use easily for the storage and retrieval of data. You can implement your own examples of CRUD apps using these tools. Let’s see what these are below!
Implement CRUD Functionality Using These Tools
A CRUD app has different parts that are integrated together to finally function properly. Each part can be developed using specific tools and technologies. Take a look at these below so that you have a better idea about CRUD apps.
User Interface (Frontend)
The user interface is the component of an application through which our users interact with our CRUD app. Your user interface design should allow the end user to perform all the basic tasks smoothly. To create a responsive design, you can use the following tools.
Figma: For creating design prototypes for the user-facing applications.
HTML & CSS: For creating user-facing applications and styling the basic web page.
React.js: For developing event-driven responsive design to perform the CRUD operations.
Angular.js: This JavaScript framework allows seamless interaction between the frontend and the backend applications.
Backend APPLICATIONS
The backend of an application is where the actual logic is implemented for CRUD software. You can implement the server-side logic and handle HTTP requests at the backend of a CRUD app. Some technologies you can use are:
Node.js: For handling server-side scripting and REST API services. It is often used with the Express.js framework.
Django: It is the Python framework to handle CRUD operations easily with built-in functions.
Database management system (DBMS)
A DBMS helps us to store and manage the data in a structured format. We have different kinds of database services for building apps. Depending on the need of the CRUD app you can select a suitable DBMS:
SQL Database: Some examples of this type are MySQL, SQLite, PostgreSQL, etc. Here, CRUD operations are handled using SQL queries.
No SQL Database: DBMS like MongoDB use document-oriented databases for storing and updating the data in JSON-like formats rather than relational databases.
Many students get stuck with their complex DB assignments and projects and seek Database Assignment Help and it’s where our coding help services come in handy.
API services AND DATABASE services
When you have reached the point of hosting your CRUD app, you will require to add new features and update apps in real time. For this, we have tools like database services and APIs. Finally, let’s get to know about these!
REST API: These are used to create an interface between the user interface and the database. APIs can help us with the HTTP protocol method (POST, GET, PUT, DELETE) easily. Using APIs helps in seamless data flow.
Firebase: Firebase is a database service that allows us to perform CRUD operations in real time. It is a cloud database that helps us to develop our CRUD app quickly.
Using the new technologies in your CRUD app helps in building projects that are scalable and accessible to all the users who interact with your app. Now, let’s see some ideas you can choose for developing your first CRUD app.
8 FUN CRUD APP IDEAS FOR DEVELOPMENT!
Whether you are a final-year student looking for project ideas or a beginner developer who has just started your coding journey and is looking to improve your coding skills, you can never go wrong at choosing to build CRUD apps. So, let us get to know about some cool project ideas for CRUD application development
1. To-Do List
A to-do list CRUD app is a great way to start your journey as a web developer. Users can create just a simple list of their daily tasks and update or delete them when completed. A to-do app is a great way of learning data manipulation using CRUD apps.
CRUD Functions In A To-Do App:
Create: Users can create a new task or add items to the to-do app.
Read: Access the list of tasks created by the users to check which tasks the user needs to complete.
Update: The users can cross off the tasks that we completed or edit the tasks. For example “buy groceries” can be modified to “buy groceries from local market.”
Delete: The delete function allows the users to remove a task from the list.
You can also add bonus features like adding reminders to your app. Now, let’s see some technologies you can use to develop this application.
Technologies you can use:
Frontend: HTML, CSS, React.js
Backend: Node.js, Django
Database: MongoDB
You can also use RESTful APIs with HTTP methods like – GET, POST, PUT and DELETE to return a specific set of “to-do’s” tasks.
Below is the Database Schema defined using DBML – Database Markup Language so that you can create your entities and define relationships between them.
Table tasks {
task_id integer
task_name varchar
user_id int
created_at timestamp
status enum('pending', 'in-progress', 'completed') [default: 'pending']
due_date date
priority enum('low', 'medium', 'high') [default: 'medium']
}
Table users {
id integer [primary key]
username varchar
role varchar
created_at timestamp
}
Ref: tasks.user_id > users.id
2. Chat App
It is another great app idea if you want to enhance your coding skills. A chat application enables users to send and receive messages in chatrooms or privately in real-time. Below, we can see the functions we can perform.
CRUD Functions In A Chat App:
Create: The first step will be to create or sign up with a username and password. Users will then be able to create a new message that they want to send.
Read: View messages that the users have sent or received in a conversation. You can also fetch the chat history from the database between the login sessions.
Update: The users can update their passwords, usernames, or profile icons. You can also add the functionality to modify the sent messages that the latest chat applications have implemented.
Delete: Users can delete their accounts, conversations, or a chat room.
To develop a chat application, you can use advanced techniques and web development technologies. However, there is a particular tech stack that is typically focused on creating user-facing applications like the chat application.
Technologies you can use:
Frontend: HTML, CSS, React.js
Backend: Node.js, Django, Socket.io (for real-time message handling)
Database: MongoDB, Firebase
MongoDB will store the user data in JSON data structure which will simplify the operations to return data like user messages effectively.
Below is the Database Schema defined using DBML – Database Markup Language so that you can create your entities and define relationships between them.
Table users {
id int [pk]
username varchar(50) [not null, unique]
email varchar(100) [not null, unique]
password varchar(255) [not null]
created_at timestamp
}
Table chats {
id int [pk]
name varchar(100) [not null] // Group name (for group chats)
is_group boolean [not null, default: false]
created_at timestamp
}
Table user_chats {
id int [pk]
user_id int
chat_id int
}
Table messages {
id int [pk]
user_id int
chat_id int
content text [not null]
created_at timestamp
}
ref: messages.user_id > users.id
ref: messages.chat_id > chats.id
ref: user_chats.user_id > users.id
ref: user_chats.chat_id > chats.id
3. Project Management Tool
Have you ever heard of tools and platforms like Jira, Smartsheet, and, Adobe Workfront? Well, these are some project management tools that help to streamline business processes by keeping track of project ideas, assignments, deadlines, updates, and more.
