Week 12 - 2020

The weeknote for 3/16 - 3/22.

MyProject

Tententen

https://github.com/monoidcc/Tententen

• Continued working on Tententen. This week I felt I almost finished the prototyping. I continue working on it next week to approach further to the end of the work.

• Continued working on it. This week I added @pub, @sub, and @innerHTML decorators. @innerHTML is the syntax sugar for the next pattern:

  @component('foo')
  class Foo {
    __mount__() {
      this.el.innerHTML = `
        <p><span>Hello, world!</span></p>
      `
    }
    ...
  }
  

  The above very frequent pattern of initializing innerHTML at mount lifecycle becomes like the below using @innerHTML decorator:

  @component('foo')
  @innerHTML(`
    <p><span>Hello, world!</span></p>
  `)
  class Foo { ... }
  

  @pub and @sub are, as their name suggest, the decorators for building pub/sub pattern in capsid components.

  @pub publishes event to the elements which have sub:{event} class. For example:

  @component("foo")
  class Foo {
    @pub("bar")
    bar() {}
  }
  

  The above bar method publishes bar event to the elements which have sub:bar class. In this case, the class name sub:bar means that the element is the subscriber of bar event.

  On the other hand, @sub decorator adds class sub:{event} to the element:

  @component("baz")
  @sub("bar")
  class Baz {
    @on("bar")
    bar() {}
  }
  

  In the above example, baz component automatically has sub:bar and therefore it becomes the subscriber of bar event. It catches the event from the corresponding @pub decorator 👍 Because we have @is decorator already, @sub(event) decorator is the simple syntax sugar for @is('sub:' + event).

  The addition of @pub and @sub significantly simplifies the communication between components and they replaces the usages of @notifies decorator. So I removed @notifies in the latest version of capsid.js.

UIT meetup vol.8

• I talked about deno at the event UIT meetup vol.8 in a VR space provided by cluster. The prepation is a little bit tougher than usual conferences because I couldn't use web browser during my talk. I was also unable to show my terminal, so I need to prepare the movie files for the demo sequences which I wanted to show during the talk. The slides are available here.
