mindeng / nom-exif

Cuándo se añadió cada estrella y fork, recopilado de GitHub y agrupado por día. El crecimiento acumulado se sitúa justo encima de las adiciones diarias que lo componen, de modo que ambos se leen en conjunto: la acumulación orgánica sostenida no se parece en nada a un pico abrupto y efímero. Cuando esa diferencia es medible, se informa como autenticidad del crecimiento.

Cada punto abarca 2 días.

Conjunto completo de dependencias resueltas según el grafo de dependencias de GitHub: 9 paquetes directos y 7 indirectos (transitivos). El cierre transitivo es completo cuando el repositorio incluye un lockfile.

El cotejo de avisos no pudo ejecutarse para este informe: No resolved dependencies carried a version and a supported ecosystem
