Hire Vue Developers

Vue earns its place on teams that value a smaller surface area and a template syntax designers can read. Its single-file components keep markup, logic and styles together, which suits products with many small screens and a mixed team, and Nuxt covers server rendering without a separate stack.

Vue’s reactivity is the reason it feels effortless and the reason its bugs are hard to see: the framework tracks dependencies for you, so the mistakes are all about accidentally stepping outside that tracking rather than about wiring something up wrongly.

The reactivity rules that actually cause bugs

Four recur often enough that we ask about them.

Destructuring a reactive object detaches the values from tracking. The code looks cleaner and the view stops updating, which is why toRefs exists and why a code review here should treat a destructured store as a question rather than a style preference.

A ref unwraps automatically in a template but not inside an array or a plain object in the template’s scope, which produces the peculiar case of a value that renders as [object Object] in one place and correctly in another.

watch and watchEffect are not interchangeable. watchEffect collects its dependencies by running, so a conditional branch that has not executed yet is not a dependency, and the watcher silently stops firing when the condition flips.

And a large list held in a deep reactive proxy pays for that depth on every mutation. shallowRef with explicit replacement is usually the fix, and knowing why is the difference between an engineer who has profiled Vue and one who has read about it.

Vue 2 is now a security question, not a preference

Vue 2 reached end of life at the end of 2023, and Nuxt 2 followed in 2024. An application still on either is not merely old; it is receiving no security patches, and the ecosystem around it has moved far enough that a dependency upgrade forced by something else can no longer be satisfied.

The migration is genuinely large, and the honest sequencing is: get to the latest Vue 2 minor with the migration build, remove the patterns that have no Vue 3 equivalent — filters, event buses, $listeners — then cross. Note also that v-if and v-for swapped precedence between versions, so a template that combined them on one element does something different after the upgrade without raising an error anywhere.

How a Pinia store stops being testable

Stores go bad in one specific way: they start reaching for things instead of receiving them. A store that imports a router, reads from local storage and calls an HTTP client directly cannot be tested without standing up all three.

The version that stays testable keeps side effects at the edges — the store holds state and pure derivations, and the composable that uses it does the fetching. It is a small discipline and it is what determines whether an application still has meaningful tests in year two.

Where Vue is the wrong choice

Where hiring depth matters more than developer experience. The Vue talent pool is smaller than React’s in most markets, and on a team you expect to grow quickly that is a real constraint rather than a snobbery.

Where a niche third-party component is essential and only exists for another framework. And where an organisation already runs several React applications — a second framework doubles the shared- component problem and halves the number of people who can move between teams.

Nuxt, and when the second runtime is worth it

Nuxt is worth it when pages must be indexable, when first paint on poor connections matters commercially, or when you genuinely want file-based routing and server handlers in one project.

It is not worth it for an application behind a login. Server rendering there buys nothing you can measure and costs you a Node process to operate, a hydration failure mode to debug, and a class of bug — code that assumed a browser and now runs on the server — that a plain single-page application simply does not have.

What we interview for

The most useful signal is whether a candidate has done a Vue 2 to Vue 3 migration. Ask how they handled the Options API components they could not rewrite, what they did about incompatible libraries, and how they typed the result. Those answers separate people who have maintained Vue from people who have started it.

Then the diagnostic: a value changes and the view does not update — talk me through what you check. Engineers who understand the reactivity system name the three or four ways tracking gets lost. Everybody else suggests forcing a re-render, which is the Vue equivalent of turning it off and on again.
