A Visual Workflow Studio Using Reusable Components

Software development often involves repetitive implementation of common functionalities such as user authentication, CRUD operations, input validation, database connectivity, and API routing. These repeated tasks increase development time, code duplication, and maintenance effort. To address these challenges, this paper proposes Visual Workflow Studio, a web-based visual workflow builder that simplifies application development through reusable software components. The proposed system provides a drag-and-drop interface that enables developers to create workflows by connecting predefined components and configuring their properties. The workflow is represented as a structured JSON definition containing component details, configurations, and connections. A workflow engine interprets this definition to manage workflow execution. The system is designed using the MERN stack, comprising MongoDB, Express.js, React.js, and Node.js. It also aims to support workflow validation, project management, and application project generation using reusable templates. By promoting component reusability and visual development, Visual Workflow Studio aims to reduce repetitive coding, improve development efficiency, and simplify workflow management
