Possible disadvantages of CodePen

  • Limited Offline Functionality
    Since CodePen is primarily an online tool, it requires an internet connection for most of its features to work, limiting its usefulness in offline environments.
  • Performance Constraints
    Complex or resource-intensive projects may not perform as well on CodePen as they would in a full-fledged local development environment.
  • Subscription Costs
    While many features are free, advanced functionalities and additional storage options require a paid subscription, which may not be ideal for all users.
  • Limited Backend Capabilities
    CodePen is primarily designed for front-end development, so it offers limited support for backend technologies, making it less suitable for full-stack or server-side development.
  • Dependency Management
    Managing dependencies and libraries can be cumbersome compared to local development environments which have better tools for this purpose, like npm.
  • Security Concerns
    Sharing projects with the public can expose your code and assets to unauthorized use, posing potential intellectual property and security risks.

  • How to use Java Records
    A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:. - Source: dev.to / almost 3 years ago
  • Why is `suspend` a language keyword, but @Composable and @Serializable are annotations
    I am all in favour to more third side libraries adding functionalities, like Lombok, Manifold and error prone. As well as smaller projects like this shameless plug and what appears in this list. Source: almost 3 years ago
  • Is there a tool to track CVEs for the software that we use?
    While at it you could also point them to static code analyzers such as error_prone, spotbugs and pmd (use all 3 at once - they complement each other in detecting different issues). Source: almost 4 years ago
  • Get rid of those boolean function parameters (2015)
    Linters can check for this sort of thing, for example Error Prone[0] has a lint[1] for this. Totally agree this is better to be in the language proper so we don't need this extra tooling.
