prettylogx 0.1.3

Beautiful, production-ready Python logging with colors and JSON output

prettylogx

Beautiful, production-ready Python logging — zero external dependencies.

Make your Python logs beautiful and readable in 3 lines of code.
No config files. No heavy dependencies. Just install and go.

---

Install

pip install prettylogx

---

Use

from prettylogx import setup_logger

logger = setup_logger("my-app")

logger.info("Server started")
logger.warning("Database is slow")
logger.error("Payment failed")

That's it. Your logs now look like this:

12:30:45  INFO      my-app            Server started
12:30:45  WARNING   my-app            Database is slow
12:30:45  ERROR     my-app            Payment failed

Each level prints in its own color — green, yellow, red, magenta.

---

More Examples

Switch to JSON logs (for production)

logger = setup_logger("my-app", json_logs=True)

logger.info("Server started")

{"timestamp": "2024-01-15T10:30:45Z", "level": "INFO", "logger": "my-app", "message": "Server started", "module": "app", "function": "main", "line": 5}

---

Show DEBUG level logs

logger = setup_logger("my-app", level="DEBUG")

logger.debug("Connecting to DB...")
logger.info("Connected")

---

Trace a request ID across all log lines

from prettylogx import setup_logger, set_request_id, clear_request_id

logger = setup_logger("api")

set_request_id("req-abc123")

logger.info("Validating input")    # → [req-abc123] Validating input
logger.info("Querying database")   # → [req-abc123] Querying database
logger.info("Returning 200 OK")    # → [req-abc123] Returning 200 OK

clear_request_id()

---

Log exceptions with full traceback

try:
    result = 1 / 0
except ZeroDivisionError:
    logger.exception("Something went wrong")

12:30:45  ERROR     my-app            Something went wrong
  - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
    Traceback (most recent call last):
      File "app.py", line 3, in <module>
        result = 1 / 0
    ZeroDivisionError: division by zero
  - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

---

Custom log levels

logger.verbose("Very detailed info")         # below DEBUG
logger.success("Order processed!")           # between INFO and WARNING

---

All Options

setup_logger(
    name="my-app",       # name shown in every log line
    level="INFO",        # DEBUG / INFO / WARNING / ERROR / CRITICAL
    json_logs=False,     # True = JSON output for production
    show_time=True,      # show timestamp
    show_file=False,     # show filename and line number
    use_colors=True,     # False = plain text, no ANSI codes
)

---

Before vs After

Without prettylogx — raw Python logging:

No colors. No alignment. Hard to scan. Every line looks the same.

---

With prettylogx — beautiful, readable logs:

Colors per level. Fixed columns. Request ID tracing. Clean exception blocks.

---
