Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Performance and event handling can still vary significantly across different operating systems despite its efforts to standardize.
Configuring Chokidar for complex directory structures or multiple file types requires a deep understanding of its API and event handling mechanisms.
Monitoring numerous files simultaneously can lead to increased memory consumption, affecting performance in resource-constrained environments.
