testing

If you want to test with the actual Slack API, you could run a script like this.

// run your local machine
import { SlackAPI } from "./../deno-slack-api/src/mod.ts";

const token =
  "your-token-here";

// initialize Slack API client
const slack = SlackAPI(token);

console.log(
  await slack.fileUploadV2({
    file_uploads: [
      {
        file: "sample",
        length: "6",
        filename: "sample.txt",
      },
    ],
  }),
);

@WilliamBergamin Thank you for your review! :smile: ⭐

My implementation, while referencing the node-slack-api, avoids implementing fields that will not be supported in the future and includes fields that will become mandatory as mandatory fields.

Since node-slack-api has been around for a long time, there's a benefit to aligning the fields used in fileUploadV2 with those used in files.upload. However, in deno-slack-api, files.upload is currently not usable, so I thought there was no need to implement fields like content or filetype.

Is this still being worked on?
