I have been playing around with Vue 3, which is really cool. So let me share some of what I have learned. According to their roadmap, they have pla...

Nice summary!
Do you know anything about what will happen with testing?
vue-test-utilsis broken with Vue 3.In the meantime, I'm also experimenting with Vue on the TodoMVC app. Good to see others are doing it also.
Looks like
vue-test-utilsfor Vue 3 has reached alpha today :) Check out vue-test-utils-nextThanks, upgraded, it works with minor bugs
Thank you!
I'm not quite sure, I haven't looked into it.
Nice, thank you for sharing the Todo app :D
So filters are gone with v3? Is that a breaking change?
Yes, it is. The main reason is that JavaScript has this ESNext Proposal: The Pipeline Operator. This may or may not happen, but if JavaScript introduces this, it would break Vue I think. So they are thinking ahead and keeping what's inside the brackets to only be valid JavaScript.
Interesting; thanks for that link. Is the proposal gaining traction? I've never heard of it before this.
I'm not quite sure actually, first time hearing about it myself :)
The pipe syntax is just a way of composing functions. That syntax has gone away in favor of the familiar way of composing functions.
So
x | y | zcan be rewritten asz(y(x)).That being said, I think there's a strong argument to be made for keeping the filter pipe syntax. It's used in unix, a lot of functional languages, Vue2, other JS frameworks, etc. It's a terrific idea.
I know it's purpose. I don't know what they gain by removing it. It's also quite popular in jinja2
Well, they are going with a new major version in Vue 3—so, breaking changes are to be expected.
Expected, but not mandatory. SemVer also reserves bumping major versions for a sweeping feature introduction (like functional components).
Is this a typo, or are both

v-enter-fromand v-leave tov-enter-from."It was a typo. Thank you for correcting me :) I have updated the article now.

The timing of your post was terrific. My boss saw it and as a result suggested we use Vue 3 on an upcoming project.
Vue 3 is now in Beta! 🥳
