Italian Municipalities JSON Database

The `comuni-json` package provides an unofficial database of Italian municipalities in a static JSON format, integrating data from official ISTAT (National Institute of Statistics) and ANCI (National Association of Italian Municipalities) sources. The npm package is currently at version `1.0.0`, with the underlying data last updated to January 1, 2020, encompassing 7904 municipalities. The project maintains an irregular release cadence, typically updating in response to new ISTAT administrative changes or Poste Italiane's CAP (Postcode) revisions. A key characteristic is its open-source nature, offering a readily accessible dataset for development and research. Crucially, the project explicitly states that the completeness and correctness of the CAP data cannot be guaranteed, making it unsuitable for professional applications requiring absolute data reliability, in contrast to commercial, paid services. The dataset structure includes fields such as `nome` (name), `codice` (ISTAT code), `zona` (geographic zone), `regione` (region), `provincia` (province), `sigla` (vehicle registration plate code), `codiceCatastale` (cadastral code), `cap` (an array of postcodes), and `popolazione` (population from the 2011 census).
