# Technical Documentation

**Demo ID**: `demo-2025-007` **Version**: `[1.0.0]` **Last Updated**: `2025-09-05`

## Architecture Overview

### System Architecture

The system integrates a Slack bot application within BSVA’s internal Slack workspace and a Next.js-based public Q\&A website.

* The Slack bot app detects emoji reactions on threaded messages to archive full threads into MongoDB.
* The public website displays shared threads and enables users to tip contributors with BSV micropayments.
* Blockchain micropayments provide economic incentives for quality participation and knowledge sharing.

### Technology Stack

* **Frontend**: Next.js 13 (React) for the shared Q\&A website
* **Backend**: Node.js Express server powering the Slack-bot with MongoDB for thread storage
* **Database**: MongoDB for persistent storage of thread metadata, messages, replies, and reactions
* **Infrastructure**: Hosted on cloud services with Slack API integration and BSV payment network connectivity

### Key Components

1. **Slack Bot App**: Reacts to `:inbox_tray:` emoji to save and update Slack threads in MongoDB
2. **Slack API Handler**: Listens for real-time message updates, edits, deletions, and emoji reactions
3. **Public Website**: Displays threads, manages BSV micropayment tipping, and interfaces with blockchain services

## Integration & APIs

| Service     | Purpose                          | Version | Documentation                                 |
| ----------- | -------------------------------- | ------- | --------------------------------------------- |
| Slack API   | Interaction with Slack workspace | Latest  | [Slack API Docs](https://api.slack.com/)      |
| MongoDB     | Thread storage and indexing      | Latest  | [MongoDB Docs](https://www.mongodb.com/docs/) |
| BSV Network | Micropayments and blockchain     | Latest  | [BSV Explorer & SDK Docs](https://bsv.dev/)   |

### API Endpoints

```bash
GET  /api/v1/threads
POST /api/v1/tips
GET  /api/v1/threads/:threadId
```

## Implementation Guide

### Prerequisites

* Node.js (v18 or later), npm/yarn
* MongoDB instance (cloud or local)
* Slack workspace admin access for bot installation and permissions
* BSV blockchain node or provider for micropayments

### Setup Instructions

Clone repositories:

Slack Threads Webapp:

```bash
git clone https://github.com/bsv-blockchain-demos/slack-threads-webapp
cd slack-threads-webapp
npm install
npm run dev
```

Slack Bot App:

```bash
git clone https://github.com/bsv-blockchain-demos/slack-bot-app
cd slack-bot-app
npm install
node app.js
```

### Configuration

Key configuration parameters:

* `SLACK_BOT_TOKEN`: Slack bot OAuth token
* `MONGO_URI`: MongoDB connection string
* `BSV_NODE_URL`: BSV blockchain node endpoint

## Testing & Validation

### Test Coverage

* **Unit Tests**: Core Slack bot event handlers and database operations covered
* **Integration Tests**: Verified end-to-end thread saving, updating, and retrieval
* **Performance Tests**: Thread saving latency < 500ms; tipping transaction time < 2 sec

### Validation Criteria

* [ ] Slack bot successfully archives threads on `:inbox_tray:` reaction
* [ ] Public site displays archived threads with up-to-date content
* [ ] BSV micropayment tips processed and confirmed on blockchain

## Performance & Scalability

### Current Metrics

* **Response Time**: API average 300ms
* **Throughput**: 50 thread saves per minute in pilot
* **Resource Usage**: Moderate CPU and memory usage on Node.js server

### Scalability Considerations

* Potential for horizontal scaling of bot app instances
* Load balancing of API backend
* Batch processing of blockchain transactions to reduce fees and latency

## Maintenance & Support

### Monitoring

* **Logs**: Centralized logging of bot events and API requests
* **Metrics**: Dashboard with thread counts, tip volumes, API performance
* **Alerts**: Notifications for failures in thread archiving or transaction failures

### Troubleshooting

| Issue                | Cause                       | Solution                       |
| -------------------- | --------------------------- | ------------------------------ |
| Slack API rate limit | Excessive requests          | Implement exponential backoff  |
| Payment failure      | Blockchain node unavailable | Retry transactions or fallback |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hub.bsvblockchain.org/demos-and-onboardings/demo-solutions/demos/slack-threads/technical-slack-threads.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
