Jsonnet features and specs

  • Configurability
    Jsonnet allows you to write configurations as code, enabling dynamic configuration generation and making it easier to manage complex configurations.
  • Extensibility
    Jsonnet supports functions and imports, enabling code reuse and modular configuration design across different files and projects.
  • JSON Compatibility
    Since Jsonnet is a JSON extension, it is fully compatible with JSON, meaning any valid JSON file is also valid in Jsonnet.
  • Reduce Repetition
    Jsonnet reduces redundancy through capabilities like variables and functions, helping to avoid repetitive configurations and boilerplate.
  • Final Manifest
    Jsonnet outputs a final manifest in JSON, providing a clean and widely-accepted data format that can be used directly by applications.

Possible disadvantages of Jsonnet

  • Learning Curve
    Jsonnet introduces new syntax and concepts (such as mixins and imports) that may require time to learn and adapt to, especially for developers familiar with plain JSON.
  • Tooling Support
    While gaining traction, Jsonnet still has limited tooling and IDE support compared to more established configuration languages or file formats.
  • Complexity in Parsing
    As a more expressive configuration language, Jsonnet may introduce complexity in parsing and understanding configuration files compared to using straightforward JSON.
  • Overhead
    The additional features and functionalities of Jsonnet can introduce computational overhead, potentially making it slower than using simple JSON for very massive configurations.

  • Levels of Configuration Languages
    Https://jsonnet.org/ I never heard of this before. This seems like the JSON I wish I really had. Of course at some point you could just use JavaScript. - Source: Hacker News / 26 days ago
  • Standard ML idiosyncrasies
    I've been reading the book Modern Compiler Implementation in ML lately. It's been helpful to brush up on some concepts while developing Tsonnet (my typed-aspiring Jsonnet flavor) and I hope to learn a ton more. However, I'm growing dissatisfied with some details -- not specifically the book, but the choice of the development environment. - Source: dev.to / about 2 months ago
  • Tsonnet, a humble beginning
    For the past 2 years, I've been working extensively with Jsonnet, a configuration language that augments JSON and helps eliminate repetition in our config files. It has its limits (many by design), which keeps the language simple to use. But there's one thing that keeps nagging at me when I'm deep in the code: what's the shape of the input or output of this function? And wouldn't it be great if we could type... - Source: dev.to / 4 months ago
