esm import fails

[rfdrake27]

Targeting esnext, importing

import ManyUpdatePlugin from 'postgraphile-plugin-many-create-update-delete';

and then using it in the appendPlugin array, appendPlugins: [ ManyUpdatePlugin, ]

will fail with the error that the appendPlugins param accepts functions, but the plugin is attempting to pass an object. However, the Typescript type is a Plugin.

If you ignore typescript warnings and import the plugin's default key, it will build appropriately:

appendPlugins: [ // @ts-ignore ManyUpdatePlugin.default, ]

1.) Can you provide your typescript version and tsconfig file? 2.) What version of node are you using? 3.) Do you have any other build steps involved?

I ran into this same issue @tjmoses

The problem and the solution are summarized at

https://arethetypeswrong.github.io/?p=postgraphile-plugin-many-create-update-delete%401.0.7

Repro steps are

1. Create an ESM module
2. Import the package
3. Run tsc to see the error

Here's my code that shows same issue; you can paste this into a blank ESM module to repro

import  ManyUpdatePlugin from 'postgraphile-plugin-many-create-update-delete';
import { createPostGraphileSchema } from 'postgraphile';

async function generateGraphQLSchema() {
	await createPostGraphileSchema('', 'app_public_v2', {
		appendPlugins: [ManyUpdatePlugin],
	});
}

and the error is

test.ts:6:19 - error TS2322: Type 'typeof import("/Users/iris/Software/folx/test/b/node_modules/postgraphile-plugin-many-create-update-delete/build/index")' is not assignable to type 'Plugin'.
  Type 'typeof import("/Users/iris/Software/folx/test/b/node_modules/postgraphile-plugin-many-create-update-delete/build/index")' provides no match for the signature '(builder: SchemaBuilder, options: Options): void | Promise<void>'.

                    ~~~~~~~~~~~~~~~~


Found 1 error in test.ts:6

The issue can be fixed either by adding an export = or by switching this module to ESM
