Prisma

Anyone with good typescript knowledge in here willing to help with an off-topic question?

Yeah… so I am trying something…

```
import { ApolloServer } from "apollo-server-express";

export class MyGraphQL extends ApolloServer
```

In my extended class’s constructor I eventually have a call to `super()`.

I compiled everything to ES5, all good.
I am now using this lib in a project of mine, when I instantiate my class, I get this error

```
 _this = _super.call(this, options) || this;

TypeError: Class constructor ApolloServer cannot be invoked without 'new'
```

Are you calling `new MyGraphQL()` anywhere?

Ha, I should specify, I am using the lib compiled in ES5 in a Node.js project (so the proj itself is not using TS)

I think you’d be better off making a gist/minimal reproduction repo and posting a link to that :slightly_smiling_face:

Who knows, perhaps you’ll discover the issue while building the reproduction :slightly_smiling_face:

the lib is supposed to be OS anyway, but the project using it is private, so I’ll have to mock something similar

Not a repo yet, but if you want to have a look: <https://github.com/apollographql/apollo-server/issues/1623>
