How to make tsup output declare module

[shuaixr]

I use knex to manage mysql connections,knex uses declare module 'knex/types/tables' to enhance type checking(knex typescript doc)

My type definition file is like this:
client.ts

import knex, { Knex } from "knex";
import knexConfig from "../knexfile";
//Init knex
export const client = knex(knexConfig);

declare module "knex/types/tables" {
//someting
}

tsc can correctly output type definition files containing declare module 'knex/types/tables', but tsup can't

@shuaixr it's doable for sure. You just have to specify it as part of your tsup.config.ts

import { defineConfig } from 'tsup'

export default defineConfig((options) => ({
  name: "package-name,
  entry: ['src/index.tsx'],
  format: ["esm"],
  bundle: true,
  clean: true,
  dts: {
    footer: "declare module 'knex/types/tables';"
  },
}))
