Slack Logger 🧵

A lightweight async logger for sending structured and text-based logs to Slack from your Rust applications.

✨ Features

✅ Simple log_info(), log_error(), log_warn() style methods
✅ Block-style logs with key-value pairs
✅ Auto-pretty-prints complex JSON data
✅ Runs asynchronously using tokio::spawn
✅ Works great for production observability and alerts

📦 Installation

Add to your Cargo.toml:

[dependencies]
slack_log = "0.1"

cargo install slack-log

⚙️ Initialization

Before using, initialize once:

use slack_log::{slack_log_initialize, SlackConfig};

slack_log_initialize(SlackConfig {
    webhook_url: "https://hooks.slack.com/services/...".into(),
    debugger: true,
});

🧪 Usage Examples

🔳 Block-style Logs

use slack_log::{log_block_success, log_block_error, log_block_info, log_block_warn, log_block, block_fields};
use serde_json::json;
use chrono::Utc;

let fields = block_fields![
    { title: "Service", value: "UI Indexer" },
    { title: "Price", value: 50000 },
    { title: "Boolean", value: false },
    { title: "Time", value: chrono::Utc::now().to_string() },
    { title: "JSON", value: json!([{ "a": 1 }, { "b": 2 }]) },
    { title: "to_string_pretty", value: serde_json::to_string_pretty(&json!([{ "a": 1 }, { "b": 2 }])).unwrap() }
];

log_block_success("Ravi bhai ka code", &fields);
log_block_error("Startup", &fields);
log_block_info("Startup", &fields);
log_block_warn("Startup", &fields);
log_block("Startup", &fields);

💬 Simple Logs

use slack_log::{log, log_info, log_warn, log_success, log_error};
use serde_json::json;

log_info("App started \njay here!!!");
log_warn(1234);
log_success(true);
log_error(json!({ "event": "shutdown", "reason": "manual" }));

let data = json!([{ "a": 1 }, { "b": 2 }]);
log(serde_json::to_string_pretty(&data).unwrap());

🧱 Macro Support

Create blocks easily with:

let fields = block_fields![
    { title: "Key", value: "Value" },
    { title: "Another", value: 123 }
];
