Exporting a module from a TypeScript definition file allows for seamless sharing

I am in the process of developing a definition file for the Vogels library, which serves as a wrapper for the AWS SDK and includes a property that exports the entire AWS SDK.

declare module "vogels" {
  import AWS = require('aws-sdk');

  export function define(modelName: String, config: any): void;
  export var AWS: AWS;      /* THIS LINE DOESN'T TRANSPILE */
}

The usage of this library is as follows:

import vogels = require('vogels');

vogels.AWS.config.update({region: region});

var model = vogels.define('test', {
  ..
  }
});

Unfortunately, exporting the AWS property from the "vogels" module poses a challenge due to AWS not being recognized as a type. Is there a way to export the AWS property without duplicating the entire AWS definitions within my module?

Answer №1

Here's a sample code snippet demonstrating how to export the complete AWS module along with the define function:

declare module "vogels" {
  import AWS = require('aws-sdk');

  function define(modelName: String, config: any): void;

  export = { AWS, define }
}

Remember that you can only have one export = statement within a module, so make sure all exported variables are included in that line (you can spread them across multiple lines if needed). Avoid exporting anything else apart from defining interfaces, variables, etc. The actual export process occurs later on.
