This repository contains the logos of provinces and districts in Indonesia. You can access it at https://jastinxyz.github.io/indonesia-logo/images/{code}.{ext}. You can make a request to data/output.json to get the code and image paths from all provinces and districts as an array. Province and city codes are based on the laravolt/indonesia package.
And is it also an alternative to laravolt/indonesia-logo which seems to have been abandoned 8 years ago?
In this repo there is also a crawler with nodejs that you can use if you want. How does the crawler work? It will take data on which districts and provinces will be scraped, then will make a request to Wikipedia and take all province and district logos with the highest resolution (if any).
