# KISS (Keep It Simple, Stupid)
|
|
|
|
## 매 한 줄
|
|
> **"매 simplest-thing-that-could-possibly-work"**. 매 1960s Lockheed Skunk Works 의 Kelly Johnson 의 aerospace heuristic → 매 software 매 universal 의 design principle. 매 sibling: YAGNI, Worse-is-Better, Occam's Razor.
|
|
|
|
## 매 핵심
|
|
|
|
### 매 mechanism
|
|
- 매 each abstraction 의 cognitive cost 의 measure.
|
|
- 매 minimum-viable design → 매 iterate.
|
|
- 매 complexity 매 emergent, never additive cheap.
|
|
|
|
### 매 forms
|
|
- **Code**: fewer lines, fewer abstractions, fewer dependencies.
|
|
- **API**: fewer endpoints, fewer params, fewer states.
|
|
- **System**: fewer services, fewer protocols, fewer config knobs.
|
|
|
|
### 매 응용
|
|
1. Pre-mature abstraction avoidance (Rule of Three).
|
|
2. Boring-tech preference (PostgreSQL > custom DB).
|
|
3. Monolith-first (Fowler), microservices later if needed.
|
|
|
|
## 💻 패턴
|
|
|
|
### KISS 매 too-complex (anti)
|
|
```ts
|
|
// Over-engineered: factory + builder + strategy for "add 2 numbers"
|
|
class AdderFactory {
|
|
static create(strategy: AddStrategy): Adder { /* ... */ }
|
|
}
|
|
```
|
|
|
|
### KISS 매 right
|
|
```ts
|
|
const add = (a: number, b: number) => a + b;
|
|
```
|
|
|
|
### Service split: simple-first
|
|
```ts
|
|
// Simple: 1 service, postgres
|
|
app.post('/order', async (req, res) => {
|
|
const order = await db.orders.create(req.body);
|
|
await sendEmail(order);
|
|
res.json(order);
|
|
});
|
|
|
|
// Only when justified by load/team-size: split into microservices.
|
|
```
|
|
|
|
### Dependency minimalism
|
|
```bash
|
|
# package.json 매 audit — every dep is liability
|
|
npm-check --unused
|
|
depcheck
|
|
```
|
|
|
|
### Config 매 default-driven
|
|
```ts
|
|
// Bad: 27 required env vars
|
|
// Good: smart defaults, override only when needed
|
|
const PORT = process.env.PORT ?? 3000;
|
|
const DB_URL = process.env.DATABASE_URL ?? 'postgres://localhost/dev';
|
|
```
|
|
|
|
### Naming for clarity
|
|
```ts
|
|
// Bad
|
|
function p(d: any[]) { /* ... */ }
|
|
|
|
// Good
|
|
function paginate(items: Item[]): Page<Item> { /* ... */ }
|
|
```
|
|
|
|
## 매 결정 기준
|
|
| 상황 | Choice |
|
|
|---|---|
|
|
| First version | Simplest possible, single file if needed |
|
|
| 매 second feature 의 same shape | Still don't abstract |
|
|
| 매 third 의 same shape (Rule of Three) | Now abstract |
|
|
|
|
**기본값**: Inline the code. Abstract only when 매 third 의 same pattern emerges.
|
|
|

|
## 🤖 LLM 활용
|
|
**언제**: design review, architecture decision, code review (cut complexity).
|
|
**언제 X**: 매 inherent-complexity domain (compilers, crypto, distributed consensus) 매 simplification 매 wrong-target.
|
|
|
|
## ❌ 안티패턴
|
|
- **Premature abstraction**: 1 use 의 abstraction 매 wrong shape.
|
|
- **Configuration explosion**: every-flag-as-knob.
|
|
- **Microservices day-one**: 매 distributed monolith 의 invitation.
|
|
|
|
## 🧪 검증 / 중복
|
|
- Verified (Kelly Johnson — Lockheed Skunk Works; Rich Hickey — Simple Made Easy talk; Worse-is-Better essay).
|
|
- 신뢰도 A.
