Vue.js Development: Clear, Maintainable Business Interfaces
Etixio delivers custom Vue.js development for your business interfaces and evolves your existing front-ends with clear, reusable components. We build new applications, migrate existing ones to Vue 3 and add AI features to them, from conversational assistants to streamed responses.
Understanding the technology
Vue.js in your project.
Vue.js is a framework for building web interfaces based on components and a reactivity system. It can be integrated into an existing application or structure a more complete one. We use it to connect screens to data and organize interactions around the user’s tasks.
The benefits for your product
Why choose Vue.js?
Vue.js suits a first product as well as an enterprise application. Because it is progressive, it can be introduced into an existing application or serve as the foundation of a complete one.
A progressive framework
You can start with a few components in an existing page, then add routing, state management and server-side rendering as needed.
Self-contained components
Single File Components bring together template, logic and style; the Composition API isolates shared behavior in composables.
A consistent official ecosystem
Vue Router, Pinia, Vue Test Utils and Vite are maintained alongside the framework, with first-class TypeScript support.
Our scope of work
The work we take on.
Components
Break down screens and share behavior with composables.
Data
Organize state, navigation, forms and API calls.
Evolution
Prepare dependency migrations and regression testing of user journeys.
We handle migrations from Vue 2 to Vue 3 and the Composition API, as well as the move from Vuex to Pinia, while preserving existing journeys.
Our Vue.js expertise
The Vue.js ecosystem we master.
Core
Vue 3 and the Composition API, TypeScript, Vue Router with navigation guards and lazy loading, Pinia for shared state.
Meta-frameworks
Nuxt for server-side and static rendering and SEO; Quasar for sharing code across web, mobile and desktop.
Component libraries
Element Plus, Vuetify or PrimeVue, adapted to your brand guidelines or replaced by a custom design system.
Tooling & testing
Vite, Vue DevTools, Vitest and Vue Test Utils for unit tests, Cypress or Playwright for end-to-end journeys.
Vue.js and AI
AI features in your Vue.js interfaces.
Vue’s reactivity lends itself well to progressively displaying a model response: a composable manages the stream, loading states, interruption and errors, while components display the text, sources and suggested actions. The model call stays on the server side, with the user’s permissions and logs.
As part of custom web development, we build these interfaces and their services, and take prototypes to production. See our AI agents and chatbots and our UX/UI for web and SaaS applications offering.
In the field
From technology to real-world use.
In a sales management tool, a change must be reflected in a form, a list and key metrics. We define where the information lives and how components share it. Loading states and API errors keep users from mistaking local input for saved data.
The choices that matter
The choices to examine before building.
Shared behavior can be isolated without turning every screen into a generic component. We examine navigation, forms and conventions for accessing services. On an existing project, migrating the framework and its libraries must preserve journeys before introducing new uses.
From work to deliverables
Delivery your team can take over.
The scope of work specifies the components to build or take over and the acceptance criteria. We provide what is needed to understand the changes, verify them and continue the work.
- Documented components and states
- Interfaces connected to APIs
- Tests of user journeys
Frequently asked questions
Vue.js development: your questions.
What is Vue.js and why use it?
Vue.js is a progressive JavaScript framework for building web interfaces. It combines a gentle learning curve, an efficient reactivity system and the ability to adopt it step by step.
Is Vue.js suitable for enterprise applications?
Yes. With Vue 3, the Composition API, TypeScript, Pinia and Nuxt, it supports complex applications maintained over the long term, provided architecture conventions are set.
What is the difference between Vue, React and Angular?
Vue is less prescriptive than Angular and provides more official tools than React. Its learning curve is generally gentler. The choice depends mainly on your team, your existing code and the product’s lifespan.
When should you use Nuxt rather than Vue alone?
Nuxt makes sense when SEO matters (server-side or static rendering), for a content site or an application that benefits from an enforced project structure. Vue alone is enough for an application behind authentication or components embedded in an existing application.
How is state managed in Vue.js?
With ref, reactive and computed for local state, composables for shared logic, and Pinia for the global state of a complex application. Pinia replaces Vuex and offers good TypeScript support.
How do you test a Vue.js application?
Unit tests with Vitest and Vue Test Utils, component tests, end-to-end tests with Cypress or Playwright on critical journeys, run in continuous integration.
How do you migrate from Vue 2 to Vue 3?
Step by step, by inventorying incompatible dependencies, migrating components to the Composition API as you go and moving from Vuex to Pinia. Tests on existing journeys secure each step.
Can an AI assistant be integrated into a Vue.js application?
Yes. The assistant becomes a set of components and a composable that consumes the streamed response, connected to a server-side service that calls the model. We add access rights, logs and evaluations for production.
What engagement models do you offer?
A fixed-price project for a defined scope, a dedicated team to evolve your application over the long term, or a targeted engagement (Vue 3 migration, move to Pinia, Nuxt).
