Possible disadvantages of Fiddler

  • Learning Curve
    May require a period of learning and adaptation for users new to the tool or those who are not familiar with HTTP/HTTPS concepts.
  • Resource Intensive
    Can be resource-heavy, especially when capturing and storing large amounts of traffic data, which may slow down your computer.
  • Limited Mobile Support
    Although it can work with mobile devices, setup can be cumbersome and less straightforward compared to desktop debugging.
  • Documentation and Community
    While there is good documentation available, it may not cover all niche use cases, and community support can be hit or miss.
  • SSL Decryption
    Decrypting HTTPS traffic requires additional setup and can introduce security risks if not handled properly.

ESLint features and specs

  • Customization
    ESLint is highly customizable through configuration files, allowing developers to tailor the linting process to fit their specific coding standards and project requirements.
  • Extensibility
    With a wide range of plugins and the ability to write custom rules, ESLint can be extended to accommodate unique project needs or additional languages and frameworks.
  • Community Support
    ESLint has a large and active community, ensuring continuous improvement, frequent updates, and a wealth of shared knowledge and resources.
  • Integrations
    ESLint integrates seamlessly with most development environments, build tools, and version control systems, making it easy to incorporate into existing workflows.
  • Error Prevention
    By statically analyzing code to catch potential errors and bad practices before runtime, ESLint helps improve code quality and reduce bugs.
  • Consistency
    Applying ESLint across a project ensures coding standards are maintained consistently, which is particularly beneficial for teams with multiple developers.

Possible disadvantages of ESLint

  • Initial Setup
    Configuring ESLint for the first time can be daunting, especially for those who are new to the tool or have complex project requirements.
  • Performance
    On large codebases, ESLint can sometimes slow down builds or editor performance due to the extensive analysis it performs.
  • Learning Curve
    There is a learning curve associated with understanding and configuring ESLint rules, which can be challenging for beginners.
  • Strictness
    Depending on the configuration, ESLint can be very strict, leading to a large number of warnings or errors that may initially overwhelm developers not accustomed to such rigorous linting.
  • Opinionated Rules
    Some ESLint default rules may not align with every developer's or team's coding style preferences, necessitating further customization and adjustment.
  • Maintenance
    Keeping ESLint configurations and plugins up to date requires ongoing maintenance, especially as projects evolve and dependencies change.

    So, I had to test this new version in a personal project to learn how to use all these new things along with other technologies and tools I’ve used for a long time and also love, like VSCode, ESLint, Prettier, and a bunch of other. And I did, but there’s a catch which makes the whole “experimental” thing have more sense: you can only use this through ng test. - Source: dev.to / about 4 hours ago
