There is a lot of buzz around the internet about Vue.js 3.0's announcement about a new composition model. There are a lot of questions about it and I think much of it is 'they moved my cheese' more than 'they're breaking everything'.
So let's talk about it...
I've been writing demos for Vue, Angular, and React for my SignalR micro-courses over on my Wilder Minds site. For Angular and React, I started out with the the SPA templates, but I found them confusing and hard to do a minimal example.
I tend to suffer from "You Moved My Cheese" and wondered if I was throwing the baby out with the bathwater. Let me talk about my experiences creating projects with and without the templates.
If you're using Vuex for state management in your Vue.js applications, there is a good chance that you need to use async operations (e.g. API calls). I have been doing this a while, but falling back to using Promises in most cases.
As I've been using async/await in C# for a while and wanted to try out async and await in JavaScript. In implementing the change, I thought I'd share how I did this in a simple Vue app.
I have to admit, my first experiences with React several years ago were meet with a lot of cynicism. The idea of mixing JavaScript and Markup made me clutch my pearls to the core.
Now I know that you can use React without using JSX, but I think that is missing the point in a lot of ways. Of course, I'm not a React expert so I am sure you'll let me know how wrong I am ; )
As many of my readers already know, I've become enamoured with Vue.js. Because of this, I've been using it more and more on projects.
Since I also deal with ASP.NET Core almost exclusively, I've been at odds with how to get the two technologies to work well together. Originally I had just used the JavaScript file, but as I've started building larger pieces, I've wanted to use projects built by the Vue CLI in ASP.NET Core. Here's how I've been doing it. Might not be right, but it's at least a way ; )
If you're building larger scale Vue objects and you're not using Vuex to centralize your state, please stop and go learn Vuex. Really.
For those of you still here, sometimes it's helpful to be able to monitor state changes to perform other tasks. For example, to send messages or communicate with servers that aren't about state (e.g. SignalR is a good example). That's where Vuex plugins come in.
A Vuex plugin is a simple function that is called once during the setup of a Vuex store. Typically you'd just create the function/arrow function taking an instance of the store:
export default store => {
};
Inside the function, you just want to subscribe to changes to the store as you need. An easy way to think about this is to use subscribe to a mutation:
If you're not in the south part of the Netherlands, you might have missed my most recent appearance last night. Great hosts, guests and sponsors make the night and easy and fun talk.
After a long day at Techorama NL, I was whisked away to Eindhoven for a talk at the .NET Zuid group (e.g. Southern .NET Group). I was able to show them the basics of Vue.js and pontificate about my continued hatred of the phrase "Single Page Applications".
Finally heading home from about a month of conferences! I can't wait to get back to my own bed, but in the mean time I've had a great time sharing talks with a lot of European developers!
This time I was in Ede, Netherlands for the first Techorama outside of Belgium. As usual, the team did an amazing job! Here are the slides and code as promised from that event:
Just got home from Music City Code conference had a great time catching up with attendees and other speakers. If you haven't made it to this great Nashville event before, plan for next year. It's well worth it.
As promised, here are the slides and code from my talks. I did talks on "Enhancing Web Pages with VueJS: When You Don't Need a full SPA" and "Versioning APIs with ASP.NET Core 2.1". Here you go:
In case you haven't been following on Twitter, you might not know that I've been working on a Vue course for a couple of months now. This particular course is now available as an Early Access model I'm trying out.
Instead of waiting and releasing the whole course, I'm publishing the course module-by-module. The idea is that Early Access gives you access to each module as I finish them.
