Vue.js Best Practices : Production Deployment

Vue.js Best Practices : Production Deployment

When it comes to deploying Vue.js applications into production, there are certain best practices that developers should follow to ensure a smooth and efficient deployment process. Vue.js has gained popularity for its simplicity, flexibility, and performance, but it’s important to employ proper techniques to optimize the application for production.

One essential practice is to utilize Vue CLI to create a production build of the application. Vue CLI is a command-line tool that helps streamline the development process and provides various features to help optimize the application. By using Vue CLI to create a production build, developers can reduce the size of the application and improve its loading speed.

Another important aspect of production deployment is to implement code splitting. Code splitting allows for the separation of the application code into smaller chunks, which can be loaded asynchronously as needed. This technique helps improve the initial loading time of the application, as only the necessary code is loaded upfront, while the rest is fetched on demand.

Furthermore, caching is a crucial practice for efficient production deployment. By properly configuring caching headers, developers can ensure that the browser caches static assets such as CSS and JavaScript files, reducing the amount of data that needs to be downloaded upon subsequent visits to the application. This improves the overall performance and user experience of the application.

These are just a few of the best practices that can be implemented during the production deployment of Vue.js applications. By following these techniques, developers can optimize their applications for performance and provide users with a seamless experience.

Setting Up a Production Environment


Setting up a production environment for your Vue.js application is an essential step before deploying it to the live servers. A production environment provides the necessary resources and configurations to ensure optimal performance and stability for your application.

Choose a Hosting Provider

Before setting up a production environment, you need to choose a suitable hosting provider. There are various options available, including shared hosting, virtual private servers (VPS), cloud hosting, and dedicated servers. Consider factors such as scalability, reliability, and cost when making your decision.

Configure the Server

Once you have chosen a hosting provider, you will need to configure the server to run your Vue.js application. Follow these steps:

  • Install a compatible web server, such as Apache or Nginx, on your server.
  • Set up a domain or subdomain for your application.
  • Install Node.js and npm on the server.
  • Clone or upload your Vue.js application files to the server.
  • Install the required dependencies using npm or yarn commands.

Build and Deploy the Application

Before deploying your Vue.js application to the production environment, you need to build it. Building involves compiling and bundling your application’s source code into optimized and minified files. To build your application, follow these steps:

  • Run the build command provided by your Vue.js build tool (e.g., Vue CLI, webpack, etc.).
  • Make sure to specify the correct production environment configuration during the build process.
  • The build process will generate a standalone bundle file(s) that you can deploy to the server.

After building the application, deploy the bundled files to the configured web server. You can use various deployment methods, such as FTP, SCP, or Git. Ensure that the files are placed in the correct directory accessible by the web server.

Configure Server-Side Rendering (SSR)

If your Vue.js application uses server-side rendering (SSR), you will need to configure the server accordingly. SSR improves performance and SEO by generating the initial HTML content on the server and sending it to the client. To configure SSR, follow these steps:

  1. Install a compatible Node.js server framework, such as Express or Koa, on your server.
  2. Create a server entry file that imports and configures your Vue.js SSR application.
  3. Configure the server framework to handle requests and render the Vue.js application.
  4. Set up the necessary routing and middleware for your SSR application.

Monitor and Test

Once your Vue.js application is deployed to the production environment, it’s important to monitor its performance and test for any issues. Use monitoring tools like New Relic or AppSignal to track the application’s performance, error rates, and resource utilization. Additionally, perform thorough testing to ensure that the application functions as intended.


Setting up a production environment for your Vue.js application involves choosing a hosting provider, configuring the server, building and deploying the application, and configuring server-side rendering if necessary. Remember to monitor the application’s performance and conduct regular testing to maintain its stability and reliability.

Optimizing Performance

1. Lazy Load Components

Lazy loading is a technique that allows us to load components or resources only when they are needed. This can significantly improve the initial loading time of your application, as it avoids downloading unnecessary code upfront.

To lazy load components in Vue.js, you can use the built-in async component feature. Instead of importing the component directly, you can use the import() function and provide the path to the component file. This will load the component asynchronously when it is needed.

Here’s an example:

Vue.component('lazy-component', () => import('./components/LazyComponent.vue'));

2. Code Splitting

Code splitting is another technique that helps optimize performance by splitting your application’s code into smaller chunks. These chunks can then be loaded on-demand, reducing the initial loading time.

In Vue.js, you can achieve code splitting by using dynamic imports with the import() function. This allows you to split your code into separate bundles that can be loaded asynchronously.

Here’s an example:

import('./components/HeavyComponent.vue').then((module) => {

// The module contains the component after it has been loaded

// You can then use it in your application

Vue.component('heavy-component', module.default);


3. Performance Profiling

Profiling your application can help identify performance bottlenecks and optimize them. Vue.js provides built-in tools for performance profiling, such as Vue Devtools and the Performance tab in Chrome DevTools.

With Vue Devtools, you can analyze the rendering performance of your components, track down excessive re-renders, and identify potential optimization opportunities.

Chrome DevTools also provides a Performance tab that allows you to record and analyze the performance of your application. You can use this tool to identify areas that can be optimized and measure the impact of your optimizations.

4. Use Component-Level Code Splitting

Instead of splitting your entire application into chunks, you can also apply component-level code splitting. This means that each component is split into its own chunk, allowing you to load only the necessary code for the current route or component.

To achieve component-level code splitting, you can use dynamic imports in Vue Router. By specifying the component’s path as a function in your route configuration, you can load the component on-demand when it is needed.

Here’s an example:

const routes = [


path: '/lazy-component',

component: () => import('./components/LazyComponent.vue'),



5. Minification and Compression

To further optimize the performance of your Vue.js application, you should enable minification and compression for your production build. Minification removes unnecessary characters from your code, such as whitespace and comments, reducing its size. Compression, on the other hand, reduces the size of your assets by compressing them using algorithms like Gzip or Brotli.

You can enable minification and compression by configuring your build tools, such as webpack or Vue CLI, to apply these optimizations when generating the production build. This will result in smaller bundle sizes and faster loading times for your application.

6. Caching and Content Delivery Networks (CDNs)

Caching and content delivery networks (CDNs) can greatly improve the performance of your Vue.js application. Caching allows the browser to store and reuse static resources, such as JavaScript and CSS files, reducing the number of requests made to the server. CDNs, on the other hand, distribute your static assets across multiple servers around the world, bringing them closer to your users and reducing latency.

You can enable caching by setting appropriate cache headers in your server configuration. This tells the browser how long it can cache the resources before requesting them again. CDNs can be integrated with your application by configuring your build tools to upload the assets to the CDN and rewrite the URLs accordingly.

7. Optimizing Vue Components

To further optimize the performance of your Vue.js components, you should follow best practices when writing them:

  • Avoid unnecessary re-renders by using the shouldComponentUpdate lifecycle hook or Vue’s built-in watch option.
  • Use functional components when possible, as they are lighter and have better performance.
  • Avoid excessive nesting of components, as each level adds an additional rendering and update overhead.
  • Use scoped CSS or CSS-in-JS solutions to reduce the size and complexity of your stylesheets.
  • Avoid unnecessary reactivity by using Object.freeze or similar techniques for static data.

8. Pre-Rendering

Pre-rendering is a technique that allows you to generate static HTML pages for your Vue.js application, reducing the initial loading time. With pre-rendering, the server generates the HTML for each route, and the static pages are served to the client.

To pre-render your Vue.js application, you can use tools like prerender-spa-plugin or vue-server-renderer. These tools render the components to HTML during the build process, allowing you to serve static pages that can be displayed immediately.

Pre-rendering is especially useful for content-driven websites or landing pages, where the content is relatively static and does not require dynamic interactions.


Optimizing the performance of your Vue.js application requires understanding and implementing various techniques and best practices. By following the tips mentioned in this article, you can greatly improve the loading speed and overall performance of your application, providing a better user experience for your users.

Minifying and Bundling Assets

One of the best practices for improving the performance of your Vue.js application is to minify and bundle your assets. Minification and bundling can greatly reduce the size of your JavaScript and CSS files, making them load faster for your users.


Minification is the process of removing unnecessary characters from your code, such as whitespace, comments, and line breaks. This can significantly reduce the size of your code without affecting its functionality. There are several tools available that can automatically minify your JavaScript and CSS files, such as UglifyJS for JavaScript and CleanCSS for CSS.

When minifying your code, make sure to also enable gzip compression on your server. Gzip compression can further reduce the size of your code by compressing it before sending it to the client.


Bundling is the process of combining multiple files into a single file. This can help reduce the number of requests that your application needs to make to the server, improving the loading speed of your application. Vue.js provides a built-in bundler called webpack, which can combine and minify your JavaScript and CSS files.

When using webpack, it’s important to configure it properly to ensure optimal performance. This includes setting the correct entry point, defining code splitting strategies, and configuring plugins to minify and optimize your code.

Code Splitting

Code splitting is a technique that allows you to split your code into smaller chunks that can be loaded on demand. This can be particularly useful for large applications, as it allows you to only load the code that is necessary for the current page, reducing the initial loading time.

Vue.js provides a code splitting feature called async components, which allows you to dynamically load components only when they are needed. This can significantly improve the performance of your application, especially for complex and resource-intensive components.


When minifying and bundling your assets, make sure to set the appropriate caching headers on your server. This will allow the browser to cache the assets and serve them from the cache on subsequent requests, further improving the loading speed of your application.

It’s also a good idea to include a version number in the file names of your bundled assets. This can help ensure that the browser fetches the latest version of the assets when you release a new version of your application.


Minifying and bundling your assets is an essential step in optimizing the performance of your Vue.js application. By reducing the size of your code and minimizing the number of requests, you can significantly improve the loading speed of your application and provide a better user experience.

Caching and Cache Busting Strategies


When deploying a Vue.js application, one important consideration is how to effectively manage caching. Caching can improve performance by storing certain resources locally on the client’s device, reducing the need for repeated download requests. However, caching can also lead to issues with stale content if not managed properly.

Types of Caching

There are several types of caching to consider when deploying a Vue.js application:

  • Browser Caching: This type of caching occurs at the client’s browser level, where the browser stores resources like images, stylesheets, and scripts locally. The next time the user visits the website, the browser can load these resources from its local cache instead of making a request to the server.
  • CDN Caching: Content Delivery Networks (CDNs) can also cache resources at their edge servers located throughout the world. This reduces the latency for users accessing the resources, as the content is served from a server that is geographically closer to them.
  • Server-Side Caching: This type of caching occurs at the server level, where the server caches responses to certain requests. This reduces the load on the server and improves response times for subsequent requests.

Cache Busting Strategies

To avoid issues with stale content, you can implement cache busting strategies in your Vue.js application. Cache busting ensures that when you make updates to your application, the client’s local cache is bypassed and they receive the latest version of the resources.

Here are some common cache busting strategies:

  1. Versioning: One approach is to include a version number or timestamp in the URLs of your static assets, such as CSS and JavaScript files. When you make updates to these files, you can increment the version number or update the timestamp. This forces the client’s browser to fetch the updated file instead of using the cached version.
  2. Content Hashing: Another approach is to append a content-based hash to the filename of your static assets. This hash is generated based on the file’s content, so whenever the content changes, the generated hash will be different. This technique ensures that the client’s browser fetches the updated file with the new hash.
  3. Cache-Control Headers: You can also use cache-control headers to control how long resources should be cached. For example, you can set the “max-age” directive to specify the maximum time that a resource should be cached before it is considered stale and needs to be revalidated.


Implementing effective caching and cache busting strategies is crucial for maintaining a performant Vue.js application in production. By properly managing caching, you can reduce the load on your server, minimize latency for users, and ensure that they’re always getting the latest version of your application’s resources.

Consider the various types of caching available, such as browser caching, CDN caching, and server-side caching, and leverage cache busting techniques like versioning, content hashing, and cache-control headers to ensure your application is always up to date.

Using Content Delivery Networks (CDNs)

A Content Delivery Network (CDN) is a distributed network of servers that delivers content to users based on their geographical location. CDNs can help improve the performance and availability of websites and web applications by reducing latency and offloading server load.

Benefits of Using CDNs

  • Improved Performance: CDNs cache static files like JavaScript, CSS, and images on servers located closer to the end users. This reduces the round-trip time and improves the overall page load speed.
  • Scalability: CDNs distribute the load across multiple servers, allowing for better scalability. This ensures that your website can handle high traffic volumes without slowing down.
  • Geographical Reach: CDNs have a global network of servers, making it easier to deliver content to users regardless of their geographical location.
  • Reliability: CDNs have built-in redundancy, ensuring that your website or application remains available even if one server goes down.

How to Use CDNs with Vue.js

In a Vue.js project, you can use CDNs to host and deliver your static assets, such as the Vue.js framework, libraries, and other dependencies. Here’s how you can integrate CDNs in your Vue.js project:

  1. Include CDNs: Add the necessary CDN links for Vue.js and any other libraries or dependencies you are using in the head section of your HTML file. For example:
Library or Dependency CDN Link
Vue.js <script src="[email protected]/dist/vue.min.js"></script>
Axios <script src="[email protected]/dist/axios.min.js"></script>
  1. Update Vue Configuration: In your Vue.js project, update the Vue configuration to use the CDN links instead of importing the libraries locally.

By using CDNs in your Vue.js project, you can take advantage of the benefits they offer, such as improved performance, scalability, and reliability. However, it’s important to keep in mind that relying heavily on CDNs means your application’s availability will depend on the availability and performance of the CDN provider.

Load Balancing and Scaling

When deploying a Vue.js app to production, it is important to consider how the application will handle increased load and traffic. Load balancing and scaling are essential techniques for ensuring that an application can handle high volumes of traffic and provide a consistent user experience.

Load Balancing

Load balancing involves distributing incoming network traffic across multiple servers to ensure that no single server becomes overwhelmed with requests. This helps to increase the overall capacity and reliability of the application.

  • Load balancers can be implemented at various points in the application infrastructure, such as in front of web servers or between different layers of an application stack.
  • There are different load balancing algorithms available, such as round robin, least connections, and IP hash, which determine how traffic is distributed among the servers.
  • Load balancers can also perform health checks on servers to ensure that they are available and functioning properly before directing traffic to them.


Scaling refers to the process of increasing the capacity of an application to handle more traffic. There are two primary types of scaling: vertical scaling and horizontal scaling.

  • Vertical scaling: This involves adding more resources, such as CPU, memory, or disk space, to an existing server or virtual machine. Vertical scaling is typically limited by the capacity of the hardware.
  • Horizontal scaling: This involves adding more servers or virtual machines to distribute the load across multiple instances. Horizontal scaling can provide greater scalability and is often achieved by adding more servers to a load balancer.

Combining Load Balancing and Scaling

To effectively handle increased load and traffic, it is common to combine load balancing and scaling techniques.

  1. Start by setting up a load balancer in front of your application servers to distribute incoming traffic.
  2. Monitor the traffic and workload on the servers to determine when scaling is necessary.
  3. When scaling, add more servers to the load balancer to distribute the load and increase capacity.
  4. Continue monitoring and scaling as needed to maintain optimal performance.

Considerations when Load Balancing and Scaling Vue.js Apps

There are some specific considerations to keep in mind when load balancing and scaling Vue.js apps:

  • Ensure that any server-side logic or state is stored in a shared location or database that is accessible to all instances of the application.
  • Use a shared session store or implement stateless authentication to ensure that user sessions are consistent across different servers.
  • Avoid storing user-specific data on the server-side unless necessary, as this can introduce complexity when scaling.
  • Consider using tools and services provided by cloud providers, such as auto-scaling groups, to automate the scaling process.
  • Regularly monitor the performance and stability of the application to identify any bottlenecks or issues that may require further scaling.
Load Balancing and Scaling Tips Best Practices
Regularly monitor server performance and traffic Use monitoring tools to track server metrics and identify any issues
Implement proper caching and optimization techniques Minimize server load and improve response times
Consider using a content delivery network (CDN) Offload static assets and improve global accessibility

Securing Your Application

Securing your Vue.js application is an important aspect of ensuring its stability and protecting user data. Here are some best practices for securing your application:

1. Use HTTPS

It is recommended to serve your Vue.js application over HTTPS to ensure secure communication between the client and the server. HTTPS encrypts the data transmitted between the client and the server, preventing unauthorized access and eavesdropping. To enable HTTPS, you need to obtain an SSL certificate and configure your server accordingly.

2. Implement Authentication and Authorization

Implementing authentication and authorization is crucial to restrict access to certain parts of your application and ensure that only authenticated users can perform certain actions. Consider using a well-established authentication mechanism such as JSON Web Tokens (JWT) or OAuth 2.0 to handle user authentication and authorization.

3. Sanitize User Input

When accepting user input, it is important to validate and sanitize it to prevent security vulnerabilities such as cross-site scripting (XSS) attacks. Use proper input validation techniques to ensure that the data entered by users does not contain any malicious code that can compromise your application.

4. Protect Sensitive Data

Avoid storing sensitive data, such as passwords or API keys, in plain text. Instead, use secure encryption algorithms to store and transmit sensitive information. Additionally, consider using environment variables or a secrets management solution to store sensitive data securely.

5. Implement Rate Limiting

To protect your application from abuse or malicious attacks, consider implementing rate limiting. Rate limiting restricts the number of requests a user or IP address can make within a certain time period, preventing automated attacks and ensuring fair usage of your application’s resources.

6. Regularly Update Dependencies

Keep your Vue.js application up to date by regularly updating its dependencies. Outdated dependencies may have security vulnerabilities that can be exploited by hackers. Maintain a regular schedule for updating your dependencies and follow best practices for dependency management.

7. Use Content Security Policy (CSP)

Content Security Policy (CSP) is a security standard that helps protect your application from various types of attacks, such as cross-site scripting (XSS) and code injection. Implementing CSP allows you to specify which resources are allowed to be loaded by your application, reducing the risk of malicious code execution.

8. Secure APIs and Backend Services

If your Vue.js application interacts with APIs or backend services, ensure that those services are also secure. Use authentication and authorization mechanisms to protect sensitive data and implement secure communication protocols such as HTTPS. Regularly audit and monitor the security of your APIs and backend services to identify and resolve any potential vulnerabilities.

Best Practice Benefits
Use HTTPS Secure communication between client and server
Implement Authentication and Authorization Control access to application features
Sanitize User Input Prevent security vulnerabilities
Protect Sensitive Data Ensure secure storage and transmission of data
Implement Rate Limiting Prevent abuse and ensure fair resource usage
Regularly Update Dependencies Stay protected from known vulnerabilities

  • Implement Automated Testing: Write unit tests, integration tests, and end-to-end tests to ensure the stability and quality of your application. Run these tests as part of the CI/CD pipeline.
  • Monitor and Analyze the Pipeline: Monitor the CI/CD pipeline for failures and bottlenecks. Analyze the results to identify improvement areas and optimize the pipeline.


Implementing Continuous Integration and Deployment practices for Vue.js projects can significantly streamline the development, testing, and deployment processes. By integrating code changes frequently and automating the deployment process, developers can reduce integration issues, catch bugs early, and deliver value to end-users faster.

Testing and Quality Assurance

In order to ensure the quality and reliability of your Vue.js application, it is important to have a thorough testing and quality assurance process in place. This will help to catch any bugs or issues before your application is deployed to production.

Unit Testing

Unit Testing

Unit tests are an essential part of any testing strategy. With unit tests, you can test individual components or functions in isolation to ensure that they behave as expected. Vue.js provides Vue Test Utils, a library that makes it easy to write unit tests for Vue components. You can use tools like Jest or Mocha to run your unit tests.

Integration Testing

Integration tests are used to test how different components or modules of your application work together. These tests help to ensure that all the parts of your application are integrated correctly and are functioning as expected. You can use tools like Cypress or Nightwatch.js to write and run integration tests for your Vue.js application.

End-to-End Testing

End-to-End (E2E) tests are designed to test the entire application flow, simulating user actions and checking that the expected results are achieved. E2E tests help to catch any issues related to the integration of different components or modules, as well as any user interface issues. Tools like Cypress or Puppeteer can be used to write E2E tests for your Vue.js application.


Linting is a process that checks your code for common errors, style violations, and other potential issues. It helps to enforce code consistency and maintainability.
