Vue.js development services that keep your existing backend
We build Vue interfaces for product teams evolving an existing application. Our Vue.js development services connect richer screens to retained APIs and plan Vue 2 to Vue 3 migrations around the dependencies you use.
01Capabilities
Vue interfaces added to the product you already run
We scope Vue within your existing application, from embedded components to a full interface.
- Product
Long structured-content interfaces
We build interfaces to capture, structure and edit long, hierarchical documents, as in the research platform we built for knowledge workers. In healthcare, the same interface also has to meet patient-data and audit requirements.
- Full stack
Vue clients integrated with .NET or Node APIs
We integrate Vue with .NET or Node.js APIs through web development. We define API responses and interface ownership, separating server data from local interaction state. The backend can stay as workflows evolve.
- Incremental
Interaction introduced screen by screen
We add Vue components screen by screen within server-rendered pages, sharing routing and session where needed. Richer interaction does not require moving every page to a single-page application.
- Portal
Membership, payment and reporting workflows
We build member registration, renewals and event entry with payments and financial reporting. The interface shows incomplete transactions and delayed provider responses, while integration supports reconciliation. We scope the connected workflow as a custom software build with a Vue client.
02Case studies
Vue products for members, research and communities
We rewrote Triathlon Ireland's membership and events platform on .NET Core and Vue.js. The work improved website management and financial monitoring. Pet4Me pairs Vue with Nuxt and Pinia; the research platform handles long structured content.

Choosing the Vue boundary and migration route
Vue fits incremental interface work when the existing product remains the foundation. We assess the team and dependency constraints before choosing the migration or rendering approach.
| Your situation | What we recommend |
|---|---|
| An existing server-rendered application, and you want richer interaction without replacing it | Add Vue progressivelyVue components can enhance existing HTML. We agree which screens become interactive and keep the client/API boundary explicit, so adoption can follow product priorities. |
| A small or mid-sized product team sharing one front-end codebase | Use VueWe choose an Options API or Composition API style for consistency. Vue Router and Pinia are ecosystem choices we assess when routing and shared state are needed; neither is a bundled requirement. |
| A Vue 2 codebase after community end of life on 31 December 2023 | Plan Vue 3 migrationWe assess dependency compatibility, application behavior and build changes before sizing the Vue 2 to Vue 3 migration. Paid extended support for Vue 2 is a separate option to assess, with its own scope. |
| Hiring front-end engineers at scale, across several markets, for several teams | Compare team fitChoose the framework your teams can recruit for in their target markets and maintain with their existing skills. Build on established React or Angular expertise when it meets those needs. Adopting Vue also requires a hiring plan and clear component ownership across teams. |
| Mostly content, where search visibility and first paint decide the outcome | Pages firstWe establish server-side rendering (SSR) or static-page requirements before adding client interaction. Nuxt belongs in that rendering assessment for a Vue application; it is separate from choosing Vue for a single interactive screen. |
| A commerce storefront on a platform you are not replacing | Start from the platformWe start with the platform's storefront and integration options through e-commerce development. Vue is selected where it fits those options and your existing application. |
Scope
We own the boundary between a Vue screen and the application around it, including where state is held and how the client consumes API data. unicrew brings 100+ senior in-house engineers across six countries. We hold ISO 27001:2022 and ISO 9001:2015 certifications, renewed through a multi-stage audit with Quay Audit UK.
Vue is the easiest of the big three front-end frameworks to hand to a mixed-skill team. On a new application, we choose the Options API or the Composition API and keep to it. Every new developer then has one mental model to learn.

A Vue migration plan your team can maintain
The repository and dependency list tell us how Vue can be introduced or updated. We return a written interface plan before moving feature by feature.
- Read the Vue version and dependenciesWe identify the Vue major version, the component API styles in use and the build setup. That includes Webpack or Vite where present, along with the packages that constrain a move to Vue 3.You getA one-page assessment of the Vue version, build setup and dependencies that determine the starting scope.
- Draw the state boundaryWe separate server data from shared interface state and local component state. Where Pinia is present, we define what its stores own and identify data held in more than one place.You getA written state boundary, including where the application currently holds duplicate copies of the same data.
- Type the shared component interfacesWe check TypeScript across Vue single-file components, starting with props and emits on the components other screens depend on. Their input and event contracts make changes reviewable across the application.You getTyped props and emits for shared components, with the remaining gaps identified.
- Release features behind the existing shellWe introduce the new interface alongside existing features, sharing routing and session. Each feature goes live in sequence so Vue adoption or a Vue 2 to Vue 3 migration can progress while the product remains in use.You getEach feature live as it lands, with its automated coverage handed over alongside it.

Clients on platform functionality and delivery
Our website’s overall functionality has been improved both in frontend possibilities and user experience as well as backend aspects of website management and financial monitoring. These are not easily qualitfiable but there has been a net gain in available staff hours for alternative projects as a result of improved website abilities reducing workload.
Artelogic invested time to understand our needs and has subsequently proposed appropriate solutions. In the end, the team’s quality deliverables have created value for cost. The EDI tool generates significant daily revenue and helps us solve order collection issues.

The API and language contracts around Vue
The backend owns the system's records; Vue owns the interaction around them. TypeScript makes the props and events between components explicit.
07Questions
Adding Vue, migrating versions and commissioning the work
We agree migration scope and delivery responsibilities against the constraints of the existing application.
Yes. We scope their work around the Vue client and the API contract with your existing application. Our QA and test automation practice supports the work; unicrew has ISTQB-certified QA engineers.
For ongoing Vue work with delivery coordination, use managed teams.
Vue's incremental adoption fits an interface being added to an existing application. React fits a team already productive in that ecosystem.
We base the choice on the application and the team's working practices. Vue does not bundle the router or store: Vue Router and Pinia are options when the interface needs routing or shared state.
A Vue 2 to Vue 3 migration starts with dependency compatibility and the changes required by the application. Vue 2 community support ended on 31 December 2023; paid extended support is a distinct option.
- Dependency and component-library compatibility.
- Reactivity and lifecycle changes in application code.
- Build changes required by the chosen toolchain.
Options API and Composition API are both supported styles. A migration does not automatically require rewriting every component in Composition API.
Yes. Vue can enhance existing HTML, so we can introduce interactive screens while retaining the surrounding server-rendered application.
We define the boundary between server data and browser state, then bundle the client code for release. Routing and session follow the existing shell where needed. The work is scoped screen by screen.
We start by reviewing the existing application and the screens or workflows you want to change. We ask for repository access and, for Vue 2, the dependency list that determines the migration scope.
The written assessment identifies the state boundary and a route for introducing or updating Vue. Most engagements start within two to four weeks.
Vue.js development services are priced against the scoped work and engagement model.
- Time and materials: billed hourly, quoted per project.
- Fixed price: outcome based, quoted per project.
- Team extension: billed monthly per team member.
For a Vue 2 migration, the dependency assessment defines what is being estimated.
Extend your application with a planned Vue interface
Share the screens you want to change, the backend they use and your current Vue version. We will define the integration boundary and the first features or migration steps to scope.
