Nuxt I18n Micro

Appearance

🚀 Performance Guide ​

📖 Introduction ​

Nuxt I18n Micro is designed with performance in mind, offering a significant improvement over traditional internationalization (i18n) modules like nuxt-i18n. This guide provides an in-depth look at the performance benefits of using Nuxt I18n Micro, and how it compares to other solutions.

🤔 Why Focus on Performance? ​

In large-scale projects and high-traffic environments, performance bottlenecks can lead to slow build times, increased memory usage, and poor server response times. These issues become more pronounced with complex i18n setups involving large translation files. Nuxt I18n Micro was built to address these challenges head-on by optimizing for speed, memory efficiency, and minimal impact on your application’s bundle size.

📊 Performance Comparison ​

We conducted a series of tests to demonstrate the performance improvements that Nuxt I18n Micro brings to the table. Below is a detailed comparison between Nuxt I18n Micro and the traditional nuxt-i18n module, based on identical conditions with a 10MB translation file on the same hardware.

⏱️ Build Time and Resource Consumption ​

Nuxt I18n
  • Total Size: 54.7 MB (3.31 MB gzip)
  • Max CPU Usage: 391.4%
  • Max Memory Usage: 8305 MB
  • Elapsed Time: 1m 31s

Nuxt I18n Micro

  • Total Size: 1.93 MB (473 kB gzip) — 96% smaller
  • Max CPU Usage: 220.1% — 44% lower
  • Max Memory Usage: 655 MB — 92% less memory
  • Elapsed Time: 0m 5s — 94% faster

🌐 Server Performance Under Load ​

We also tested server performance by simulating 10,000 requests to each module.

Nuxt I18n
  • Requests per Second: 49.05 [#/sec] (mean)
  • Time per Request: 611.599 ms (mean)
  • Max Memory Usage: 703.73 MB

Nuxt I18n Micro

  • Requests per Second: 61.18 [#/sec] (mean) — 25% more requests per second
  • Time per Request: 490.379 ms (mean) — 20% faster
  • Max Memory Usage: 323.00 MB — 54% less memory usage

🔍 Interpretation of Results ​

These tests clearly indicate that Nuxt I18n Micro offers superior performance across multiple metrics:

  • 🗜️ Smaller Bundle Size: Reduces the overall size of your application bundle, leading to faster load times and better user experience.
  • 🔋 Lower CPU Usage: Decreases the load on your server’s CPU, allowing for more efficient processing of requests.
  • 🧠 Reduced Memory Consumption: Significantly lowers memory usage, minimizing the risk of memory leaks and enabling your application to handle larger workloads.
  • 🕒 Faster Build Times: Drastically reduces build times, which is particularly beneficial during development and CI/CD processes.

⚙️ Key Optimizations ​

🛠️ Minimalist Design ​

Nuxt I18n Micro is built around a minimalist architecture, using only 5 components (1 module and 4 plugins). This reduces overhead and simplifies the internal logic, leading to improved performance.

🚦 Efficient Routing ​

Unlike other i18n modules that generate a separate route for each locale, Nuxt I18n Micro uses dynamic regex-based routing. This approach generates only two routes regardless of the number of locales, significantly reducing the complexity of your routing configuration and speeding up route resolution.

📂 Streamlined Translation Loading ​

The module supports only JSON files for translations, with a clear separation between global and page-specific files. This ensures that only the necessary translation data is loaded at any given time, further enhancing performance.

💾 Caching and Pre-rendering ​

To optimize performance, Nuxt I18n Micro implements caching and supports pre-rendering of translation files:

  • 🗄️ Caching: Translations are cached after the initial load, reducing the need for subsequent requests and improving response times.
  • 🏁 Pre-rendering: During the build process, translation files for all configured locales and routes can be pre-rendered. This eliminates the need for runtime requests, ensuring that translations are served quickly and efficiently.

📝 Tips for Maximizing Performance ​

Here are a few tips to ensure you get the best performance out of Nuxt I18n Micro:

  • 📉 Limit Locale Data: Only include the locales you need in your project to keep the bundle size small.
  • 🗂️ Use Page-Specific Translations: Organize your translation files by page to avoid loading unnecessary data.
  • 💾 Enable Caching: Make use of the caching features to reduce server load and improve response times.
  • 🏁 Leverage Pre-rendering: Pre-render your translations to speed up page loads and reduce runtime overhead.
