How to Create a Bot on Slack and Implement Image Content Translation Using ChatGPT and Node.js

Enhance your team’s productivity by creating a custom Slack bot capable of translating image content. This step-by-step guide will show you how to leverage ChatGPT and Node.js to add this innovative feature to your Slack workspace.

Step 1: Initiate Your Slack Application

1. Begin by visiting the Slack API page and select “Create New App.”

2. Once your app is created, access Settings > Basic Information to retrieve your Signing Secret and add it to your .env file as SLACK_SIGNING_SECRET.

3. Generate an App-Level Token with Generate Token and Scopes and record it in your .env file as SLACK_APP_TOKEN.

4. Install your app to your workspace from Features > OAuth & Permissions to obtain the Bot User OAuth Token, noted as SLACK_BOT_TOKEN in your .env.

5. Assign necessary bot scopes under Features > OAuth & Permissions > Scopes, including:

  • app_mentions:read
  • chat:write
  • chat:write.public
  • im:history
  • im:read
  • im:write
  • incoming-webhook


6. Add the user token scope channels:read under Features > OAuth & Permissions > User Token Scopes.

7. Activate event handling in Features > Event Subscriptions.

8. Turn on Socket Mode within Settings > Socket Mode.

Step 2: Configure Your Bot

  1. Clone the sample bot repository from get-text-slack-app.
  2. Transition to the project directory using:
    cd app_slack
    
  3. Install necessary dependencies with:
    yarn
    
  4. Launch your bot by executing:
    node index.js
    

Step 3: Enable Image Content Translation

1. Extract Image from Message and Convert to ArrayBuffer

let imgUrl = event?.files[0]?.url_private;
const downloadFile = () =>
    axios({
      url: imgUrl,
      headers: {
        Authorization: `Bearer ${process.env.SLACK_BOT_TOKEN}`, // Slack requires authorization for file access
      },
      responseType: "arraybuffer",
    }).then((res) => res.data);
const res = await downloadFile();


2. Implement Text Recognition Software

Install Tesseract.js with:

npm install tesseract.js

Activate text recognition using:

const { createWorker } = require("tesseract.js");

const worker = await createWorker();
await worker.loadLanguage("jpn+eng+vie"); // Specify languages as needed
await worker.initialize("jpn+eng+vie");
const { data: { text } } = await worker.recognize(res);
await worker.terminate();


3. Customize ChatGPT for Translation Tasks

Train ChatGPT via OpenAI’s API:

const completion = await openai.createChatCompletion({
    model: "gpt-3.5-turbo",
    messages: [
      { role: "system", content: "You are a good translator" },
      { role: "user", content: "Xin chào, tôi là Đoan" },
      { role: "assistant", content: "Vietnamese: Xin chào, tôi là Đoan\nEnglish: Hello, I am Doan" },
      { role: "user", content: "Hello, I am Doan" },
      { role: "assistant", content: "Vietnamese: Xin chào, tôi là Doan\nEnglish: Hello, I am Doan" },
      { role: "user", content: "受 診 者 情 報 の 登 録 ・ 更 新 を し て く だ さ い" },
      { role: "assistant", content: "Vietnamese: Đăng ký và cập nhật thông tin bệnh nhân\nEnglish: Register and update patient information" },
      { role: "user", content: text },
    ],
    temperature: 0.7,
    top_p: 1,
    max_tokens: 1000,
});
return completion.data.choices[0].message.content;
