Actual behavior:

I am creating sequelize models as a shared lib for microservice-like backend architecture so the models can be imported over multiple repos. Our backend is coded with Typescript so I used sequelize-typescript to support TS in the shared model repo. Everything seems working well, but actually every sequelize types being used inside sequelize-typescript types are inferred to any in my microservice repos.

Expected behavior:

I would like to get all the shared functions and variables output with accurate sequelize types. I spent a couple days on this issue for investigation. Look microsoft/TypeScript#23918

Steps to reproduce:

Related code:

My shared model example:

import { Model, Table } from 'sequelize-typescript';

@Table({
  timestamps: true,
  underscored: true,
  tableName: 'members'
})
export class Members extends Model {
  // Columns
  ...
}

How to use the model above in my backend repos:

import { Members } from '@xxx/models';
...
const member = await Members.findOne({
  where: { xx: xx }
}); // member is inferred to any. findOne function should be inferred to Promise<Member>.

Thank you for your help in advance @RobinBuschmann

I'm still having this exact issue, even after installing Bluebird types.
