How to inject custom provider?

[uyloal]

I want to inject a database service but did not find any way to do. How to solve it?

For example, #711 mentioned the 'provide' option, like this:

import { PrismaClient } from "@prisma/client";

// plugins/prisma.ts
export default defineNitroPlugin((nitroApp) => {
  const prisma = new PrismaClient();

  return {
    provide: {
      db: prisma
    }
  };
});

Any tips on how to implement it in the current version？

You can use a nitro middleware and do sth. like:

import { PrismaClient } from '@prisma/client'

let prisma
export default defineEventHandler((event) => {
  if (!prisma) {
    prisma = new PrismaClient()
  }
  event.context.prisma = prisma
})

Will this be implemented in plugins?
