Nitro module

[MickL]

Clear and concise description of the problem

Can we have a module @intlify/nitro for Nitro v3 too?

It will probably just be a super thin wrapper for better DX. Otherwise, just a readme/documentation would be great too because it seems fairly simple to use @intlify/h3.

For the time being, @intlify/h3 can be used but this is not documented anywhere. Here is my plugin, please note that I already detected the current locale in a middleware before and placed it into event.context so it is always available, the locale can also be detected in the plugin instead:

import { definePlugin } from 'nitro';
import { defineIntlifyMiddleware } from '@intlify/h3';
import { i18nConfig } from '~/i18n/i18n.config';

export default definePlugin((nitroApp) => {
  const { onRequest, onResponse } = defineIntlifyMiddleware({
    ...i18nConfig,
    locale: (event) => event.context.locale,
  });

  nitroApp.hooks.hook('request', onRequest);
  nitroApp.hooks.hook('response', onResponse);
});

I'm a bit concerned about this.

Nitro can use web frameworks like Hono and Elysia, not just H3, via server entries.
Personally, I'd like to support plugins for Nitro, but I'm unsure how to approach this considering those web frameworks.

@pi0
Considering the above, I would greatly appreciate it if you could tell me how to support the nitro plugin! 🙏

Nitro universally uses srvx for compatibility with Web standard frameworks (H3, Hono, Elysia, etc) and Node (Express, etc).

At the moment there is no standard context between framework middleware (working on a RFC to publish soon)

I think best action at this time would be mainly focus on documentation (Nitro v3 usage with built-in middleware and API routes via h3 middleware)

Thanks! I'll try to write the docs for Nitro v3

[pi0]

Feel free to ping me, would be happy to review and help.

@kazupon @pi0 What I noticed is that now (with Nitro v2 beta?) I get an error in my IDE with the above Nitro plugin, even tho it still works fine:

TS2345: Argument of type Middleware is not assignable to parameter of type
(event: HTTPEvent<EventHandlerRequest>) => void | Promise<void>
Target signature provides too few arguments. Expected 2 or more, but got 1

Btw. I made a PR to place my Nitro usage-example into the readme: #208
