Vue.js has become one of the most popular frontend frameworks for building interactive web applications. Combined with WordPress as a headless CMS, Vue.js lets you build fast, reactive single-page applications (SPAs) that leverage WordPress’s content management capabilities. This combination gives you a modern frontend experience with a proven backend.
This guide covers how to build SPAs with WordPress and Vue.js, from setting up the development environment to deploying the finished application.
Architecture Overview
A WordPress + Vue.js SPA has two parts: the WordPress backend that serves content via the REST API or WPGraphQL, and the Vue.js frontend that consumes the API and renders the user interface. The two parts can be deployed separately — WordPress on any PHP host, Vue.js on a static host like Netlify or Vercel — and communicate via HTTP.
This decoupled architecture offers several advantages: the frontend can be updated independently of the backend, the frontend can be served from a CDN for global performance, and the WordPress admin is hidden from public access for improved security.
Setting Up the Development Environment
Create a new Vue.js project using the Vue CLI or Vite. Install vue-router for client-side routing and axios or fetch for API requests. Set up your WordPress installation with the REST API enabled. Optionally install WPGraphQL for a more flexible GraphQL API. Create environment variables for your WordPress API URL and authentication credentials.
Configure CORS on your WordPress server to accept requests from your Vue.js development server. Use the WordPress REST API’s built-in CORS support or add custom headers with a plugin.
Building the SPA
Create Vue components for your site’s pages: homepage, blog archive, single post, pages, and custom post types. Use vue-router to define routes that map to WordPress content. In each component, fetch data from the WordPress API using the created() or mounted() lifecycle hook, and display it with Vue’s template syntax.
Handle loading states with conditional rendering. Show a loading spinner while data is being fetched, and handle errors gracefully when API requests fail. Implement pagination for archive pages using Vue components that connect to WordPress’s pagination parameters.
Authentication
If your SPA needs user authentication — for members-only content, user profiles, or form submissions — implement JWT (JSON Web Token) authentication. The JWT Authentication for WP REST API plugin adds JWT support to WordPress. Store the token in localStorage or an HTTP-only cookie, and include it in the Authorization header of authenticated API requests.
Build Vue components for login, registration, and password reset. Use Vue Router’s navigation guards to protect routes that require authentication. Implement token refresh logic to keep users logged in across sessions.
Deployment
Build your Vue.js application for production with npm run build. The output is a dist folder containing static HTML, CSS, and JavaScript files. Deploy these files to any static host — Netlify, Vercel, or an S3 bucket. Configure the host to route all requests to index.html for client-side routing to work.
Deploy your WordPress backend to any PHP host. It doesn’t need to be high-performance since it only serves API requests, not rendered pages. Use a VPS or managed WordPress host and configure caching at the API level if needed.
The Bottom Line
Vue.js and WordPress are a powerful combination for building modern web applications. WordPress handles content management, and Vue.js handles the user interface with reactive components, client-side routing, and fast page transitions. The architecture is flexible enough for anything from a simple blog to a complex web application. If you’re building a site that needs rich interactivity but don’t want to give up WordPress’s content management capabilities, this stack is worth exploring.
