Not able to set INTEGER length for column

[ChristianVaughn]

Issue

I am porting my models from normal sequelize to sequelize-typescript. I am trying to define a column on my model and give it a type of INTEGER(N).UNSIGNED to match what is in my mysql database. Some examples of my code are(names of models redacted):

@Table({modelName: 'modelName', tableName: 'modelNames'})
export class ModelName extends Model<ModelName> {

  @PrimaryKey
  @AutoIncrement
  @Column(DataType.INTEGER.UNSIGNED)
  id: number

  @Column(DataType.INTEGER(2).UNSIGNED)
  buildMajor: number

  @Column(DataType.INTEGER(3).UNSIGNED)
  buildMinor: number

Versions

• sequelize: 5.22.5
• sequelize-typescript: 1.1.0
• typescript: 3.7.3

Actual behavior

On doing this both when trying to build for release, and in the VsCode intelisense i get an error such as

src/models/ModelNameHere.ts:71:28 - error TS2769: No overload matches this call.
  Overload 1 of 2, '(options?: NumberDataTypeOptions): IntegerDataType', gave the following error.
    Type '3' has no properties in common with type 'NumberDataTypeOptions'.
  Overload 2 of 2, '(options?: NumberDataTypeOptions): NumberDataType', gave the following error.
    Type '3' has no properties in common with type 'NumberDataTypeOptions'.

71   @Column(DataType.INTEGER(3).UNSIGNED)

Expected behavior

According to documentation You should be able to define a length of the integer via (N) because sequelize typescript uses the same DataType as sequelize.

Steps to reproduce

Create a model with a table and some columns. Try to make the datatype of a column DataType.INTEGER(2) or DataType.INTEGER(2).UNSIGNED where 2 can be replaced with any number that's allowed for an int length in mysql

FYI, as a temporary solution, I worked around it this way:

import { DataTypes, NumberDataTypeOptions } from 'sequelize';

DataType.INTEGER(3 as NumberDataTypeOptions)

You can leverage the NumbreDataTypeOptions interface by using them

import {DataType} from "sequelize-typescript"
DataType.INTEGER({length:2}).UNSIGNED

But if you really want use DataType.INTEGER(2) you can create a declaration.d.ts file in the root folder of your project and paste this

import { DataTypeAbstract,NumberDataType, NumberDataTypeOptions} from "sequelize";

declare module "sequelize"{
    interface NumberDataTypeConstructor extends DataTypeAbstract {
        options: NumberDataTypeOptions;
        UNSIGNED: this;
        ZEROFILL: this;
        new (options?: NumberDataTypeOptions): NumberDataType;
        (options?: NumberDataTypeOptions): NumberDataType;
        new (length?: number): NumberDataType;
        (length?: number): NumberDataType;
        validate(value: unknown): boolean;
    }
}
