A CRUD (Create, Read, Update, Delete) Applications is necessary to manage data in modern web and mobile applications. It allows users to effectively add, load, edit and delete records. Traditionally, CRUD creation required extensive coding, but with a low code platform, developers can make the process more efficient using pre-created components, automated workflows and artificial intelligence tools.

This guide will guide you by creating a fully functional application CRUD, using the development of low codes to save time, shorten errors and increase productivity-inz sacrifice flexibility or control over the architecture of your application.

What is CRUD Application?

CRUD Application Allows users:

• Create- add new records to the database
• Read- Get and display records
• Update- Edit existing records
• Delete- Remove records from database

These functions are the core of ERP systems, inventory management applications, customer databases and more.

Why Use FAB Builder for CRUD Applications?

FAB Builder is a powerful low-code and code generation platform that simplifies CRUD application development for web and mobile. With AI-powered automation, pre-built templates, and seamless integration for MERN, MEAN, React, Node.js, Java, and Flutter, it enables fast and efficient development.

Key Features:

• Automated Code Generation– Instantly generate high-quality, error-free code for front-end, back-end, and mobile apps.
• Customizable Templates– Use pre-built templates or modify them for quick deployment.
• Seamless Integration– Works with local and cloud-based development environments.
• Collaborative Workflow– Enables teams to work together efficiently on a single platform.
• Rapid Prototyping– Convert wireframes into working code in minutes.
• Cross-Platform Support– Build fully native, responsive apps for web, mobile, and desktop.

By reducing manual coding efforts, FAB Builder accelerates development, minimizes errors, and enhances productivity—making it the perfect solution for building CRUD applications efficiently. With FAB Studio you can develop CRUD without writing excessive code while having flexibility to customize the backend.

How to Set CRUD app in FAB Builder?

How to Create a New Project?

1. Log in to FAB Builder and open FAB Studio.
2. Click "Create a new app" and select "start from Scratch".
3. Select the type of database (SQL, NOSQL or external API).
4. Define your data model with the necessary tables and fields.

How to Define a Database Scheme?

For this tutorial we create an application for user management with the following diagram:

Table: Users

Creating a database table in FAB Builder

FAB Builder allows you to visually define the diagram but if you want to customize it with SQL, use:

CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  email VARCHAR(100) UNIQUE NOT NULL,
  role VARCHAR(10) CHECK (role IN ('Admin', 'User')) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

How to Create a User Interface?

Designing an efficient user interface for CRUD application includes structuring forms, tables and interactive elements to ensure trouble -free data management.

Steps to create a user interface:

• Create layout: Use containers, grids and sections for logical content organization.
• Add Input Fields: Use text boxes, drop -down menus and date collectors to enter user data.
• Design Data Table: Records with Sorting, Filter and Stage For better usability.
• Action Buttons Implementation: Include Add, Edit, Delete and Save for CRUD operations.
• To improve the user experience: Use modals for editing, instructions and accuracy verification instructions.

Well structured user interface ensures smooth navigation, improves user interaction and increases the overall efficiency of the application.

If you want to customize the user interface using JavaScript, you can do this:

document.getElementById("addUserBtn").addEventListener("click", function() {
  document.getElementById("userForm").style.display = "block";
});

How to Implement CRUD Operations?

FAB Builder automates backend processes, but you can still write your own API calls.

Create (add users)

FAB automatically binds the form fields to the database, but here is your own API approach:

async function createUser() {
  const userData = {
    name: document.getElementById("name").value,
    email: document.getElementById("email").value,
    role: document.getElementById("role").value
  };

  const response = await fetch("/api/users", {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify(userData),
  });

  if (response.ok) {
    alert("User added successfully!");
    fetchUsers(); // Refresh user list
  }
}

Read (load users)

You want to see users in the table, load data from the database:

async function fetchUsers() {
  const response = await fetch("/api/users");
  const users = await response.json();

  let tableRows = "";
  users.forEach(user => {
    tableRows += `<tr>
      <td>${user.name}</td>
      <td>${user.email}</td>
      <td>${user.role}</td>
      <td>
        <button onclick="editUser(${user.id})">Edit</button>
        <button onclick="deleteUser(${user.id})">Delete</button>
      </td>
    </tr>`;
  });

  document.getElementById("userTableBody").innerHTML = tableRows;
}

Update (Edit User Details)

You want to edit user data, use:

async function updateUser(id) {
  const updatedData = {
    name: document.getElementById("editName").value,
    email: document.getElementById("editEmail").value,
    role: document.getElementById("editRole").value
  };

  const response = await fetch(`/api/users/${id}`, {
    method: "PUT",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify(updatedData),
  });

  if (response.ok) {
    alert("User updated successfully!");
    fetchUsers(); // Refresh user list
  }
}

Delete (Remove User)

Delete user record:

async function deleteUser(id) {
  const response = await fetch(`/api/users/${id}`, { method: "DELETE" });

  if (response.ok) {
    alert("User deleted!");
    fetchUsers(); // Refresh user list
  }
}

How to Deploy CRUD App?

Once the CRUD app is completed:

• Click "Deploy" in FAB Studio.
• Select Hosting options (cloud or external FAB server).
• Set user role and permissions.
• Enable FAB Analytics User Interaction Track.

How to Improve CRUD App using AI and Automation?

FAB Builder integrates Dueled AI function to improve your application:

• Code generator AI- Generate automatically complex API logic
• FAB Analytics- Follow User Behavior and Optimize Performance
• Automated Work Procedures- Starting Actions (eg Send E -mail when registering a new user)
• Tools for Customer Experience- Connect users in descriptions and banners via page pilot

Conclusion

Building A CRUD Application with Low code platform simplifies development, reduces manual encoding and speeds up deployment. With automated code generation and smooth integration can create scalable and efficient applications with minimal effort.

Usage low code automation and AI driven can make business procedures more efficient, increase cooperation and focus more on innovations rather than recurring coding tasks. Whether you are a developer, a startup or a business, a low-code approach ensures faster market time and greater flexibility for modern application development.
