# Modern Environment Ecosystem
## 매 한 줄
> **"매 2026 dev environment 매 reproducible, fast, AI-assisted"**. 매 Docker (2013) → 매 nix/devcontainer/devbox → 매 Bun/Deno + AI editors (Cursor, Claude Code) 의 stack. 매 lockfile + container + AI agent 의 trinity.
## 매 핵심
### 매 layers (2026 stack)
1. **Hardware**: M-series Mac, Linux (Asahi/native), Cloud VM.
2. **OS / shell**: macOS / Linux + zsh / fish, atuin, starship.
3. **Package manager**: brew, mise, nix, devbox.
4. **Lang runtime**: Bun (1.2+), Deno (2.x), Node 22 LTS, Python 3.13 + uv, Rust 1.85.
5. **Container**: Docker Desktop, Podman, OrbStack.
6. **Editor**: Cursor, Claude Code (CLI), VSCode + Copilot.
7. **CI**: GitHub Actions, Buildkite, Dagger.
### 매 modern shifts (2025-2026)
- Bun replacing npm/pnpm/tsc/jest in many JS projects.
- uv replacing pip/poetry in Python.
- AI-first editors (Cursor, Claude Code) 매 default.
- Devcontainers (.devcontainer.json) 매 reproducible setup.
### 매 응용
1. Onboarding-day-zero — clone + 1-command setup.
2. CI parity with local.
3. Multi-repo monorepo workflows.
## 💻 패턴
### `mise` (asdf successor) for tool versioning
```toml
# .mise.toml
[tools]
node = "22.14.0"
python = "3.13.2"
bun = "1.2.0"
go = "1.23"
```
### `devcontainer.json` (VSCode / Codespaces)
```json
{
"name": "app-dev",
"image": "mcr.microsoft.com/devcontainers/typescript-node:22",
"features": {
"ghcr.io/devcontainers/features/docker-in-docker:2": {},
"ghcr.io/devcontainers/features/git:1": {}
},
"postCreateCommand": "bun install",
"customizations": { "vscode": { "extensions": ["dbaeumer.vscode-eslint"] } }
}
```
### Bun project (replaces node + npm + tsc + jest)
```bash
bun init
bun add hono
bun run dev # built-in --watch
bun test # built-in test runner
bun build ./src/index.ts --target=bun
```
### Python with `uv` (10-100x pip)
```bash
uv init
uv add fastapi uvicorn
uv run uvicorn main:app --reload
uv lock --upgrade
```
### Devbox (nix-based, simpler)
```json
{
"packages": ["nodejs@22", "python@3.13", "postgresql@16"],
"shell": { "init_hook": ["echo welcome"] }
}
```
### Claude Code as default agent
```bash
claude # interactive
claude /init # generate CLAUDE.md
claude /review # review pending PR
```
### CI (GitHub Actions, modern matrix)
```yaml
jobs:
test:
strategy:
matrix: { os: [ubuntu-24.04, macos-14], bun: ['1.2'] }
runs-on: ${{ matrix.os }}
steps:
- uses: actions/checkout@v4
- uses: oven-sh/setup-bun@v2
with: { bun-version: ${{ matrix.bun }} }
- run: bun install --frozen-lockfile
- run: bun test
```
## 매 결정 기준
| Need | Tool (2026) |
|---|---|
| JS runtime/package | Bun |
| Python deps | uv |
| Tool versioning | mise |
| Reproducible env | devcontainer / devbox |
| AI coding | Cursor / Claude Code |
**기본값**: mise + Bun (JS) + uv (Python) + devcontainer + Claude Code.
## 🔗 Graph
- 부모: [[Developer-Experience]]
- 응용: [[Monorepo]] · [[CI-CD-Pipeline]]
- Adjacent: [[Bun]] · [[Deno]] · [[Claude-Code]]
## 🤖 LLM 활용
**언제**: setting up new project, onboarding, CI parity.
**언제 X**: legacy frozen environments (use whatever already works).
## ❌ 안티패턴
- **Global installs**: 매 version drift.
- **Untracked tool versions**: 매 "works on my machine".
- **Skipping lockfile commits**: 매 reproducibility 매 broken.
## 🧪 검증 / 중복
- Verified (mise.jdx.dev, bun.sh, docs.astral.sh/uv, GitHub devcontainer spec).
- 신뢰도 A.
