There are a couple ways to extract map tiles from the various archives - the most popular being MBTiles and PMTiles these days. The best way, though, is using tile-join from felt/tippecanoe:
tile-join -e dir/ input.pmtiles
This will output all tiles as a hierarchy in dir - dir/{z}/{x}/{y}.{ext}. When working with vector tiles, you might need to specify -pC (no tile compression). By default, tiles are compressed in the archive, but if you need the raw tiles in a directory, specifying this option will output the raw, uncompressed files.
Put simply, Varnish is a “reverse proxy” - a piece of software that goes between the main server and the client. Basically what it does is caches content, so PHP (or whatever backend you’re using) doesn’t need to run for every single request - this makes perfect sense with static content. For sites like WordPress, filled with mostly static content, Varnish will work out of the box (minor configuration changes are required for small things).
As many of you are aware, I have been working for about 6 months now, with 2 other people.
On July 4th, we are pleased to announce that we have officially become a company, Flagship LLC. We have some pretty cool projects lined up in the near future, I’ll be posting updates on our released projects (and maybe if you’re lucky, bits and pieces of unreleased projects) here!
Our goal as a company is multi-fold, but I feel that the most important facet of Flagship is to bring modern web development and standards to Japan. In a country where Japanese translations of English reference material is prominent, especially in technology, we strive to be the flagship of truly born-in-Japan material.
