elm-semantic-dom: Syntactic sugar for cooking with Elm VirtualDom


  1. The code you use to generate your Elm program's view doesn't need to look like HTML or SVG markup.
  2. The functions in elm-lang/html and elm-lang/svg are just wrappers for VirtualDom functions.
  3. There's no reason why you shouldn't build abstractions for view components directly on top of VirtualDom — it gives you more flexibility.
  4. Because VirtualDom is intended for advanced use and customization, it's a bare-bones package without helpers that would make it's functionality easier to manipulate.
  5. So: I created a set of helper functions for working with VirtualDom and put them all in one package with semantically structured modules.
  6. The package is intended as an infrastructure for building higher level abstractions on top of VirtualDom, without the need to import Html or Svg.
  7. All functions in this package are designed to be used in the "pipeline" style, where data flows through a series of functions in an easily readable way, from top to bottom and left to right.
  8. Functions are also written to avoid unused arguments, with additional "custom" functions available for rarely-used cases.
  9. The idea behind my semantic naming schema is that the module name should always be used when invoking a function; it improves the readability and maintainability of Elm code, and you will never have to resolve errors due to conflicting function names from imported modules. So, when you import a module from this package, I recommend that you don't expose any function names. Then you can use Dom.Element.container and Dom.Keyed.container in the same module without overthinking it.
  10. I am aware that module naming scheme I chose conflicts with elm-lang/dom, which could be a problem but doesn't have to be. To avoid a compiler error when there is a need to manage DOM effects, I created danielnarey/elm-semantic-effects to wrap elm-lang/dom. When the two "dom" are not both listed as imports in the elm-package.json file, there is no compiler error, even if both packages are dependencies.
  11. Constructive suggestions are welcome!
