Prove your Vue.js skills

Vue is approachable, which means many people list it after one tutorial. Lemma separates them from practitioners with evidence of how you handle reactivity, composables and state in sessions and adaptive tests.

How Vue.js is assessed

What Vue.js competence looks like

A skilled Vue developer understands why something is reactive and why something else is not. They know when a ref is enough, when a reactive object helps, and why destructuring can quietly break reactivity. Computed values do the derived work; watchers are kept for side effects.

They organise logic into composables that read like small, testable functions, design components with clear props and emitted events, and keep shared state in a store only when it is truly shared. They are also comfortable with single-file components, scoped styles and the build tooling around them.

Clear reasoning on reactivity system. Talked through trade-offs first.

Added to Vue.jsAdded to record

Reactivity system

Refs, reactive objects and computed values, and the patterns that accidentally lose reactivity.

Composition API

Writing composables that encapsulate logic cleanly and can be shared across components.

Component communication

Props, emitted events, slots and provide and inject, used without creating hidden coupling.

State management

Using a store such as Pinia for shared state and keeping local state local.

Routing

Vue Router setup, navigation guards, lazy-loaded routes and passing params safely.

Rendering performance

Avoiding unnecessary watchers, using keys correctly and splitting large components.

What counts as evidence of Vue.js skills?

Listing Vue.js on a profile proves nothing on its own. What counts is a component you shipped, a session where someone watched you debug one, or a test you passed. These are the records Lemma can hold for your Vue.js skill, and where each one comes from. See the evidence methodology for how each source is weighed.

Live session

Composable design in a live session

Refactor a component's logic into a composable with a practitioner. They see how you handle reactivity and component boundaries, then rate the session.

Adaptive assessment

Adaptive Vue.js assessment

Scenario questions test reactivity pitfalls, watchers versus computed values and component communication. Some show a component that stopped updating, and you choose the cause.

GitHub connector

A Vue project connected through GitHub

Link a repository or commit that shows your components and composables. Lemma checks it exists and that you can access it.

Vercel connector

A deployed Vue app

Connect a Vercel deployment of a Vue application you built, so your record includes software that actually runs.

How is a Vue.js skills test run on Lemma?

The Vue.js test is adaptive: 15 to 25 questions, each picked from how you answered the last, built around real interface bugs rather than trivia. Its result joins your live sessions and linked repositories or deployments in your Vue.js SCI, which also weighs how recent the evidence is.

  1. Refactor with a practitioner

    Book a live session and work on real Vue code: extract a composable, untangle props and events, or fix a reactivity bug. The practitioner rates how you reason, not just the result.

  2. Take the adaptive assessment

    Questions adjust to your answers and cover reactivity, the composition API, routing and state. Harder scenarios count for more, each question is timed, and there is no going back.

  3. Add your shipped work

    Connect GitHub or Vercel projects so your Vue sessions and assessment sit beside real code. Keep the evidence recent, because older work counts for less over time.

Vue.js skills: common questions

How do I show Vue.js experience to a hiring manager?

Show a working Vue project, a recent assessment result and a session rating from a practitioner who watched you work. On Lemma those sit under one Vue.js skill on your Passport, which you choose to share.

Should I learn the Options API or the Composition API?

Most new Vue code uses the Composition API, so it is the better place to invest. Many existing codebases still use the Options API, so read both comfortably. Lemma's Vue sessions and assessment focus on composition patterns and reactivity, with Options API questions where they matter.

What are common Vue.js reactivity mistakes?

Destructuring a reactive object and losing reactivity, using a watcher where a computed value would do, mutating props, and forgetting keys in lists. These come up in Lemma's Vue assessment because they are the bugs that reach production most often.

Is Vue.js worth proving if most jobs ask for React?

Yes, if Vue is what you use. Plenty of teams build with it, and strong evidence in one framework shows you understand component design generally. You can build React evidence separately, and each skill keeps its own score.
