I spend quite a bit of time scouring the web for great content on Vue.
Over time I've found myself going to back to a few places over and over again.
Many of these you've probably heard of, but hopefully you'll find a few gems in this list.
It's certainly not exhaustive, but these sites have consistently good Vue content, and are updated frequently.
So, in no particular order, here they are:
Markus has written some amazing articles on more advanced topics in Vue. His stuff is super high quality and always an interesting read.
The official Vue news, which is updated weekly. They post news about upcoming Vue releases, great articles, and new libraries you can use in your Vue apps. They also have a newsletter you can sign up for.
Anthony Gore runs Vue JS Developers which has a ton of great articles and courses for Vue. He also has a weekly newsletter where he collects some of the best Vue articles.
There is also a Facebook group if you want to join a community and chat about Vue with others.
Curated by Alex Jover, a VueJS community member, this site has a collection of short and easy to digest tips on improving your code. This one also has a newsletter, with a new tip sent out each week!
The quality of content here varies quite substantially because it's a community site, but there are some great posts in here as well.
Flavio is a machine, writing a post a day for the past 2-3 years. His writing varies across many different web dev topics, but he has quite a collection on Vue. Lots of good introductory and intermediate material on his blog.
A tutorial site that you may not have heard of yet, this site has a huge collection of Vue articles from a number of different authors.
Alligator also has a bunch of articles on Vue, covering a lot of introductory and intermediate topics as well.
