|
|
Priorities: developer productivity (40%), ecosystem (30%), performance (30%).
|
|
```
|
|
|
|
### Calculate TCO
|
|
|
|
```
|
|
Calculate 5-year TCO for Next.js on Vercel.
|
|
Team: 8 developers. Hosting: $2500/month. Growth: 40%/year.
|
|
```
|
|
|
|
### Assess Migration
|
|
|
|
```
|
|
Evaluate migrating from Angular.js to React.
|
|
Codebase: 50,000 lines, 200 components. Team: 6 developers.
|
|
```
|
|

|
|
## Input Formats
|
|
|
|
The evaluator accepts three input formats:
|
|
|
|
**Text** - Natural language queries
|
|
```
|
|
Compare PostgreSQL vs MongoDB for our e-commerce platform.
|
|
```
|
|
|
|
**YAML** - Structured input for automation
|
|
```yaml
|
|
comparison:
|
|
technologies: ["React", "Vue"]
|
|
use_case: "SaaS dashboard"
|
|
weights:
|
|
ecosystem: 30
|
|
performance: 25
|
|
developer_experience: 45
|
|
```
|
|
|
|
**JSON** - Programmatic integration
|
|
```json
|
|
{
|
|
"technologies": ["React", "Vue"],
|
|
"use_case": "SaaS dashboard"
|
|
}
|
|
```
