Hi 👋
Three years ago I started my freelancing journey:
  • I worked for 3 projects in full-time
  • I increased my daily rate by +25%
  • I switched my focus from Angular to React to Vue
  • I regret nothing 😜
In this issue, I show you how you can debug computed properties in Vue and how you can use type predicates in TypeScript to narrow down types.
Additionally, I published a new blog post about creating a Markdown file-base blog using Nuxt Content v2.
Have a great week ☀️

Vue Tip: Debug Computed Properties
We can debug computed properties by passing computed() a second options object with onTrack and onTrigger callbacks:
  • onTrack will be called when a reactive property or ref is tracked as a dependency.
  • onTrigger will be called when the watcher callback is triggered by the mutation of a dependency.
Both callbacks will receive debugger events in the same format as component debug hooks.
Keep in mind: onTrack and onTrigger computed options only work in development mode.
