Change response of Pagination

[NishargShah]

I'm using a great extension that helps eliminate a lot of repetitive code in my application. It works well, but I want to change the response format from [Data[], Meta] to { docs: Data[], meta: Meta }.

I know I could wrap the response using a custom function, but I’d prefer to handle this directly within the Prisma client extension. That way, the rest of the team won’t have to remember to apply a wrapper manually. It will ensure consistency and reduce the chance of mistakes.

Here's what I tried:

const paginate = createPaginator({
  pages: {
    includePageCount: true,
  },
});

const prismaClient = new PrismaClient().$extends({
  model: {
    $allModels: {
      paginate() {
        return paginate(); // I tried passing the args from paginate and this, but no luck
      },
    },
  },
});

However, this results in the following error:

TypeError: Cannot read properties of undefined (reading 'findMany')
    at /<my_workspace>/node_modules/.pnpm/prisma-extension-pagination@0.7.5_@prisma+client@6.8.2_prisma@6.8.2_typescript@5.8.3__typescript@5.8.3_/node_modules/prisma-extension-pagination/dist/page-number.js:22:19

I also attempted to extend the withPages method but encountered the same issue. How can I modify the response shape directly within the Prisma client extension so it returns { docs, meta } instead of an array?

No update on this issue ? I encountered the same problem

Within the paginate function there are functions that reference this, but calling paginate() directly won't work. It needs to be a method of the object. Untested, but either make the function a method directly

const paginate = createPaginator({
  pages: {
    includePageCount: true,
  },
});

const prismaClient = new PrismaClient().$extends({
  model: {
    $allModels: {
      paginate,
    },
  },
});

or if you have some reason for the nesting, you can bind to the current this (and you would need to forward the args):

const prismaClient = new PrismaClient().$extends({
  model: {
    $allModels: {
      paginate(...args) {
        // only useful if you need to do stuff here, otherwise use above
        return paginate.appy(this, args);
      },
    },
  },
});
