Making Web Component properties behave closer to the platform

• gecko-dev

  78 3,116 10.0

  Read-only Git mirror of the Mercurial gecko repositories at https://hg.mozilla.org. How to contribute: https://firefox-source-docs.mozilla.org/contributing/contribution_quickref.html

  

You can see how Mozilla tests the compliance of their built-in elements in the Gecko repository (the ok and is assertions are defined in their SimpleTest testing framework). And here's the Web Platform Tests' reflection harness, with data for each built-in element in sibling files, that almost every browser pass.

• fast

  38 9,015 7.4 TypeScript

  The adaptive interface system for modern web experiences.

  

I know FAST is not used that much but I wanted to cover it as it seems to be the only library that reflects attributes by default. By default it won't do any type coercion unless you use the mode: "boolean", which works almost like an HTML boolean attribute, except an attribute present but with the value "false" will coerce to a property value of false!

• stencil

  55 12,292 9.9 TypeScript

  A toolchain for building scalable, enterprise-ready component systems on top of TypeScript and Web Component standards. Stencil components can be distributed natively to React, Angular, Vue, and traditional web developers from a single, framework-agnostic codebase.

  

First a disclosure: I never actually used Stencil, only played with it a bit locally in a hello-world project while writing this post.

• proposal-decorators

  64 2,646 4.2

  Decorators for ES6 classes

  

Because many rules are common to many attributes (the coerceType operation is defined by WebIDL, or using similar rules, and the HTML specification defines a handful of microsyntaxes for the parseValue and stringifyValue operations), those could be packaged up in a helper library. And with decorators coming to ECMAScript (and already available in TypeScript), those could be greatly simplified:
