Possible disadvantages of Cal.com

  • Learning Curve
    Although it is highly customizable, the plethora of options and features may result in a steeper learning curve for new users who are not familiar with such scheduling tools.
  • Limited Free Version
    The free version of Cal.com comes with limitations that may not be sufficient for growing businesses or advanced users who require more comprehensive features.
  • Dependency on Integrations
    Cal.com's effectiveness heavily depends on its integrations. Without these integrations, some users might find the tool less useful or incomplete, especially if their primary tools are not supported.
  • Support
    While open-source has many benefits, it may also mean that immediate, personalized support could be limited compared to fully commercial solutions. This might pose a challenge for users needing quick resolutions.
  • Performance
    As an open-source platform, the performance might vary depending on how it is hosted and managed. Suboptimal configurations could lead to slower performance or downtimes.

AngularJS features and specs

  • Two-way data binding
    AngularJS's two-way data binding feature synchronizes data between the model and the view components, reducing the amount of boilerplate code required for data manipulation and improving ease of use.
  • Dependency Injection
    The built-in dependency injection mechanism in AngularJS facilitates better organization and management of services, making the code more modular, testable, and reusable.
  • Modular Development
    AngularJS allows developers to break down applications into modules. This modular approach helps in better code organization, easier maintenance, and parallel development.
  • Community and Ecosystem
    Backed by Google, AngularJS has a large and active community. This extensive support system provides a wealth of resources, plugins, and third-party tools that can facilitate the development process.
  • Directives
    Directives in AngularJS allow developers to extend HTML with new attributes and elements, enabling the creation of custom and reusable components with ease.
  • MVVM Architecture
    The Model-View-ViewModel (MVVM) architecture promotes the separation of concerns, allowing developers to work on different parts of the application without interfering with each other.

Possible disadvantages of AngularJS

  • Performance Issues
    AngularJS's two-way data binding can induce performance issues in large applications due to the constant checking and updating of the binding, which can impact the overall application speed.
  • Steep Learning Curve
    The complexity of AngularJS, with its various concepts such as directives, dependency injection, and MVVM architecture, can present a steep learning curve for new developers.
  • Migration Challenges
    Migrating from AngularJS to newer versions like Angular (2+), which are fundamentally different, poses significant challenges and often requires a complete codebase rewrite.
  • Verbose Code
    AngularJS's syntax can sometimes lead to verbose and complicated code, which can be difficult to read and maintain, especially for large-scale applications.
  • Limited Mobile Support
    Despite its strengths, AngularJS does not offer the same level of performance optimization for mobile applications, making it less ideal for mobile-first development compared to some other frameworks.
  • Legacy Framework
    AngularJS is considered a legacy framework with a focus shifted towards Angular (2+). As a result, it receives fewer updates and less community attention compared to newer frameworks.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago

  • Between Diapers and Development – How My Blog Came to Life with Eleventy
    To maximize learning, I could choose something new. Normally, I consider that a valid reason. But given my limited time, that wasn't a priority for me. Another criterion could be long-term viability: Is there a large core team and an active community? Well, who still remembers AngularJS? From Google? And didn’t Facebook/Meta start Jest? I wouldn’t rely too much on that. - Source: dev.to / about 1 month ago
