COMMON PAKCAGES

Common Packages

Beberapa package yang sering dipakai

HTTP & API

• requests - HTTP client sederhana
• httpx - HTTP client modern
• fastapi / flask - web framework
• uvicorn / gunicorn - ASGI/WSGI server

Data & Serialization

• pydantic - data validation & parsing (wajib kalau FastAPI)
• python-dotenv - baca .env env vars
• sqlalchemy - ORM / DB toolkit
• alembic - DB migrations untuk SQLAlchecmy

Utilities / Quantity

• rich - output terminal yang cakep
• loguru - logging
• pytest - testing
• black, isort, flake8 / ruff, mypy - formatting, linting, type checking

other

• pathlib - path handling
• asyncio - async framework
• dataclasses - simple class without boilerplate
• python-dotenv - load environment variables
• numpy - fundamental numerical library
• pandas - dataframe / data processing

pyproject.toml

• file konfigurasi standar untuk python modern
• mirip package.json kalau di Nodejs atau compose.json di PHP

Contoh tanpa poetry

[project]
name = "my-app"
version = "0.1.0"
description = "Simple API using FastAPI"
authors = [
  { name = "Pythonia", email = "pythonia@example.com" }
]
requires-python = ">=3.12"

dependencies = [
  "fastapi",
  "uvicorn[standard]",
  "pydantic>=2.0.0",
]

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

Penjelasan singkat:

• [project]
  • name, version → identitas project (wajib kalau mau dijadikan package)
  • requires-python → versi Python minimal
  • dependencies → daftar package dari PyPI
• [build-system]
  • requires → library yang dibutuhkan untuk proses build
  • build-backend → tool yg dipakai untuk build (setuptools/poetry/pdm/dll) Untuk pure app internal (bukan library yang mau dipublish), ini sudah cukup.

Contoh dengan poetry

[tool.poetry]
name = "my-fastapi-app"
version = "0.1.0"
description = "FastAPI backend for my project"
authors = ["Pythonia <pythonia@example.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.12"
fastapi = "^0.115.0"
uvicorn = { extras = ["standard"], version = "^0.30.0" }
pydantic = "^2.9.0"
python-dotenv = "^1.0.1"
sqlalchemy = "^2.0.0"

[tool.poetry.group.dev.dependencies]
pytest = "^8.0.0"
black = "^24.0.0"
ruff = "^0.7.0"
mypy = "^1.11.0"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Penjelasan:

• [tool.poetry]
  • metadata project (nama, versi, author)
• [tool.poetry.dependencies]
  • dependency utama (prod)
• [tool.poetry.group.dev.dependencies]
  • dependency khusus dev (testing, linting)
• [build-system]
  • Poetry memakai poetry-core sebagai build backend

Install package:

poetry add fastapi
poetry add --group dev pytest

Poetry akan otomatis update pyproject.toml dan poetry.lock

Konfigurasi tools di pyproject.toml

Contoh

• Black
• Ruff (linter)
• pytest
