  • Multi-location Management

  • Role-based Access
    Provide administrators and trainers with access appropriate to their responsibilities.
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Questions & Answers

As answered by people managing Klunivo and Modular JavaScript.

Who are some of the biggest customers of your product?

Klunivo's answer

Klunivo is currently in its early commercial stage, so customer names are not yet publicly disclosed.

What makes your product unique?

Klunivo's answer

Klunivo combines the day-to-day operations of a sports club in one platform: members, parents and children, groups, schedules, memberships, payments, attendance, communication, documents, and events. It is designed around the real workflows of clubs running recurring group classes rather than being a generic CRM adapted to sports.

Why should a person choose your product over its competitors?

Klunivo's answer

Klunivo focuses on simplicity, practical automation, and the complete club workflow. Instead of managing schedules in one tool, payments in another, attendance in spreadsheets, and communication through messaging apps, clubs can manage everything from one system. It is especially well suited for organizations working with groups, memberships, children and parents.

How would you describe the primary audience of your product?

Klunivo's answer

Klunivo is built primarily for sports clubs and organizations running recurring group classes, typically with dozens or hundreds of members. This includes martial arts academies, BJJ and MMA clubs, dance schools, swimming schools, gymnastics and acrobatics clubs, football academies, Pilates and yoga studios, and other sports or activity-based organizations.

What's the story behind your product?

Klunivo's answer

Klunivo started after seeing the same operational problems repeatedly in sports clubs: unpaid memberships, manual payment tracking, schedules managed in spreadsheets, attendance recorded separately, documents scattered across different tools, and owners answering the same questions through WhatsApp and Messenger. The idea was simple: let coaches focus on coaching while the system handles more of the administrative work.

Which are the primary technologies used for building your product?

Klunivo's answer

Klunivo is built using a modern web stack including Next.js and React on the frontend, Node.js on the backend, PostgreSQL as the database, and Prisma for data access. The platform is deployed using Vercel and Railway and integrates with services such as Stripe and Resend.
