🚀 nitro v3

[pi0]

Note

This PR is not to merge but you can overview undergoing major nitro v2...v3 breaking changes which will be mostly breaking changes and removals in the first step.

Note

We will keep backporting fixes as much as possible to the nitro v2 until the community adoption of nitro v3. For non-breaking change improvements, please base PR branches on v2 branch. For proposing breaking changes, you can use main. Most of the upcoming features will land to v2 as well ~> v2.10.0 release tracker

⌛ ETA: Within June with the collaboration of the Nuxt team to sync releases

---

Beta testing via nightly channel

Directly using nitro:

  "devDependencies": {
    "nitro": "npm:nitro-nightly@3x"
  },

Using nitro with other frameworks such as Nuxt:

  "resolutions": {
    "nitropack": "npm:nitropack-nightly@3x"
  },

(use overrides for npm)

May I ask what the status of v3 is? :) I see the last commit is from june.

Our team is considering to use Nitro for a huge project.

@MickL Lots of things happening in h3 v2 right now to unblock last steps. (spoiler: it will be 10x faster no cheating & web apis, expect better testing ways and more)

[MickL]

Sounds amazing! Better testing would be huge.

Any ETA on h3 v2 and Nitro v3 from todays perspective?

Curious as well! 10x speed and Web APIs sound awesome

@pi0 you may want to update the ETA in the first post as ut kinda causes confusion on some social platforms. I think Nuxt already removed their ETA too.
