Modernising Our JavaScript – Vue.js To The Rescue

@ajsutton: Modernising Our JavaScript – Vue.js to the Rescue: Wherein Vue.js works where Angular didn’t (for us).

I’ve previously written about how Angular 2 didn’t work out for us, our second attempt was to use Vue.js which has much far more successful. The biggest difference with Angular is that it’s a much smaller library. It has far less functionality included in the box but a wide range of plugins to flesh out functionality as needed. That avoided the two big issues we had with Angular 2:

Build times were faster because there were way fewer dependencies to install, manage and bundle together. Not using Typescript may have also helped but I never had a clear indication of how much that affected build time.

It integrated much more easily with our existing system because it didn’t try to do everything. We just kept using the bits of our system that worked well.

We’ve been so happy with how Vue.js fits in for us, we’re now in the process of replacing the things we had built in Angular 2 with Vue.js versions.

We set out looking for a more modern UI framework primarily because we wanted the data binding functionality they provide. As expected, that’s been a very big benefit for any parts of the UI that are even slightly more than simple CRUD. We were using mustache for our templates and the extra power and flexibility of Vue’s templating has been a big advantage. There is a risk of making the templates too complex and hard to understand, but that’s mitigated by how easy it is to break out separate components that are narrowly focused.

In fact, the component model has turned out to be the single biggest advantage of Vue over jquery. We did have some patterns built up around jquery that enabled component like behaviour but they were very primitive compared to what Vue provides. We’ve got a growing library of reusable components already that all fit in nicely with the existing look and feel of the UI.

The benefit of components is so great that I’d use Vue even for very straight-forward UIs where jquery by itself could handle it simply. Vue adds almost no overhead in terms of complexity and makes the delineation of responsibilities between components very clear which leads to often unexpected re-usability. With mixins it’s also possible to reuse cross-cutting concerns easily.

All those components wind up being built in .vue files which combine HTML, JavaScript and styles for the component into one file. I was quite sceptical of this at first but Vue provides a good justification for the decision and in practice it works really well as long as you are a bit disciplined at splitting things out into separate files if they become at all complex. Typically I try to have the code in the .vue file entirely focused on managing the component state and split out the details of interacting with anything external (e.g. calling server APIs and parsing responses) into helper files.

Ultimately, it’s the component system that is really bringing us the most value which is a bit of a surprise given we had expected data-binding to be the real powerhouse. And data-binding is great, but it’s got nothing on the advantages of a clear component system that’s at just the right level of opinionated-ness for our system. We’re not only building UIs faster, but the UIs we build are better because any time we spend polishing a component applies everywhere it’s used.

I’m really struggling to think of a case where I wouldn’t use Vue now, and if I found one it would likely only be because one of the other similar options (e.g. Angular 2) was a better fit for that case.
