#VPS RAM limit exceeded when building

Hi, whenever I build my Nuxt 4 website, the build process exceeds my VPS available RAM. Which is more than 4,5 GB in most cases. As I monitor from 'htop' command, the build process starts with around 500M ram and ends with 4777M or maybe more, and then crashes with signal SIGKILL.

How to limit RAM usage when building Nuxt?

I am currently building with Dockerfile through "RUN bun run build"

Hi @coral geode. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

I'm sorry, but the knowledge sources do not provide a direct method to limit RAM usage during the Nuxt 4 build process, whether using Bun or Node.js. There are no documented build flags or configuration options in Nuxt's official documentation to cap memory usage during the build phase.

However, some related best practices and community experiences may help:

  • Building large Nuxt projects can consume significant memory, especially in Docker or on limited VPS environments. This is a known challenge, but no official solution is documented for memory limiting during build.
  • Some users have reported that switching from standard Docker builds to using docker buildx build can resolve certain build hang or resource issues, though this is not guaranteed to reduce memory usage specifically Nuxt build hanging in Docker.
  • The official Docker deployment guides for Nuxt Content and general Nuxt apps do not mention memory limiting strategies during build, but recommend multi-stage builds to keep the final image small, not to reduce build-time memory Deploy with Docker.
  • There are ongoing efforts in the Nuxt codebase to improve memory usage, such as deallocating out-of-scope references and optimizing payload caching, but these are mostly runtime improvements and may not significantly affect build-time memory perf: deallocate out-of-scope references, perf(nuxt): use browser cache for payloads, perf(nuxt): use getters to reduce template string copies in vfs.
#

Summary:
There is no documented way in the official Nuxt 4 or Bun build process to limit RAM usage during the build. If your build consistently exceeds available RAM, you may need to increase your VPS resources, optimize your project to reduce build complexity, or try building on a machine with more memory and deploying the output to your VPS.

If you need further help, consider opening an issue on the Nuxt GitHub repository with details about your project and build environment.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@coral geode Kapa.ai is still learning and improving, please let me know how I did by reacting below.

It seems like Bun is taking too much RAM...
