# LeadForge
High-performance Rust CLI for **concurrent lead generation from real-world data
sources**.
`leadforge` fetches and processes job listings (currently from **Hacker News**)
using an **async streaming pipeline with bounded concurrency, retry logic, and
filtering** — designed for building real lead generation workflows.
The tool is built for developers, freelancers, and founders who want to
**extract actionable opportunities from live data**.

# Features
### Concurrent Data Fetching
Fetches job postings using **bounded concurrency** via async streams.
This allows hundreds of requests to be processed efficiently without
overwhelming the system or the API.
---
### Streaming Pipeline Architecture
Jobs are processed as a stream:
```
job IDs
↓
async fetch (concurrent)
↓
retry + timeout handling
↓
filtering (keyword)
↓
collected results
```
Benefits:
* efficient resource usage
* fast time-to-first-result
* scalable to large datasets
---
### Retry & Resilience
Built-in retry logic with exponential backoff handles:
* network timeouts
* connection failures
* server errors (5xx)
* rate limiting (429)
This makes `leadforge` robust against unreliable APIs.
---
### Keyword Filtering
Filter results directly in the pipeline:
* case-insensitive matching
* applied during streaming (no extra pass)
Example:
```bash
leadforge hacker-news --keyword rust
```
---
### Structured Output (JSON)
Results are returned as structured JSON, making it easy to:
* pipe into other tools
* store results
* integrate with scripts or APIs
---
# Example
Fetch the latest 5 Hacker News job postings:
```bash
leadforge hacker-news --limit 5
```
Example output:
```json
[
{
"id": 47251163,
"by": "yeldarb",
"score": 1,
"time": 1772646584,
"title": "Roboflow (YC S20) Is Hiring a Security Engineer for AI Infra",
"url": "https://roboflow.com/careers",
"text": null
}
]
```
---
# Real-World Usage
`leadforge` can be used as a **lead discovery engine**:
### Find Rust jobs
```bash
leadforge hacker-news --keyword rust --limit 20
```
---
### Save results to a file
```bash
leadforge hacker-news --limit 50 > jobs.json
```
---
### Pipe into other tools
```bash
leadforge hacker-news --keyword remote \
---
# CLI Options
| `--limit <N>` | Maximum number of job postings to return |
| `--max-concurrency` | Maximum number of concurrent HTTP requests |
| `--max-retries` | Retry attempts per request on transient failures |
| `--timeout` | Request timeout in seconds (per request) |
| `--keyword` | Filter results by keyword in job title |
Example:
```bash
leadforge hacker-news \
--limit 20 \
--max-concurrency 50 \
--max-retries 3 \
--timeout 10 \
--keyword rust
```

# Documentation
Generate full Rust documentation locally:
```bash
cargo doc --open
```
Key components:
* `run` — core execution entry point
* `LeadForgeCommand` — command abstraction layer
* `fetch_jobs` — async pipeline for job ingestion
* `LeadForgeError` — structured error handling
---
# Architecture
`leadforge` is structured as a clean layered system:
```
CLI (clap)
↓
Command conversion
↓
Execution (run)
↓
Async pipeline (streams + concurrency)
↓
HTTP client (reqwest)
```
This separation allows:
* easy extension to new data sources
* clean testing
* reusable core logic
---
# Performance
The tool is optimized for:
* high concurrency
* low overhead per request
* minimal blocking
Performance depends on:
* network latency
* API responsiveness
* concurrency settings
---
# Installation
## Build from Source
```bash
git clone https://github.com/writeonlycode/leadforge
cd leadforge
cargo build --release
```
Binary:
```bash
target/release/leadforge
```
---
# Why Rust?
Rust allows `leadforge` to combine:
* **high concurrency without threads explosion**
* **memory safety**
* **predictable performance**
* **zero-cost abstractions**
This makes it ideal for **data ingestion pipelines and lead generation tools**.
