Why does my Nuxt 3 dev server take so long to start up?

Hey everyone, I’m kinda new to Nuxt and I’m a bit confused. I just set up a fresh Nuxt 3.15 project and added Nuxt UI. The app is totally empty - no components or anything else besides Nuxt UI. But when I try to run npm run dev, it’s super slow. It takes like 25+ seconds to get going. Is this normal? Or did I mess something up?

Here’s what I’m seeing in the console:

√ Found local icon collections: cool-icons
√ Vite client: done in 300ms
√ Vite server: finished in 900ms
√ Nuxt Nitro server: built in 3000 ms
i Vite client warmed up: 2500ms
i Vite server warmed up: 8000ms

Am I doing something wrong? Or is this just how Nuxt 3 rolls? Any tips to speed things up would be awesome. Thanks!

hey grace, i feel ya! nuxt 3 can be a bit sluggish at first. try clearing your node_modules and reinstalling. also, check if you have any heavy plugins or config slowing things down. if nothing helps, maybe consider using vite’s --force flag to bypass the cache. hope this helps!

As someone who’s been using Nuxt 3 for a while now, I can tell you that those startup times aren’t unusual, especially with Nuxt UI added to the mix. The first load always takes longer because it’s compiling everything from scratch.

One thing that’s helped me is using pnpm instead of npm. It’s generally faster and more efficient with dependencies. Also, make sure you’re running the latest version of Node.js - older versions can really slow things down.

Another trick I’ve found useful is to run the dev server in a separate terminal window and just leave it running. That way, you’re not constantly restarting it and waiting for that initial compilation. Hot module replacement usually handles most changes pretty quickly after that.

Lastly, if you’re on Windows, consider using WSL2 for development. I’ve noticed significantly better performance compared to running Node directly on Windows.

I’ve encountered similar startup times with Nuxt 3 projects. While it’s not ideal, it’s not entirely uncommon, especially with additional packages like Nuxt UI. A few things to consider:

  1. SSD vs HDD: If you’re not using an SSD, that could significantly impact startup times.

  2. Machine specs: Lower-end hardware might struggle more with the initial compilation.

  3. Development environment: Some IDEs or text editors with heavy extensions can slow things down.

  4. Nuxt modules: Each additional module increases startup time.

To potentially improve performance, try running ‘npm run build’ before ‘npm run dev’. This pre-compiles some assets and can lead to faster subsequent startups. Also, ensure you’re using the latest Node.js version compatible with Nuxt 3.
