## Resolving Dependencies
### Short version
Minetest uses `/api/packages/<author>/<name>/dependencies/?only_hard=1` to find out the hard
dependencies for a package.
Then, it resolves each dependency recursively.
Say you're resolving for `basic_materials`, then it will attempt to find the mod in this order:
1. It first checks installed mods in the game and mods folder (ie: `mods/basic_materials/`)
2. Then it looks on ContentDB for exact name matches (ie: `VanessaE/basic_materials`)
3. Then it looks on ContentDB for modpacks which contain (=provides) the modname
(ie: `VanessaE/dreambuilder`)
### Long version
When installing a package, an API request is made to ContentDB to find out the dependencies.
If there are no dependencies, then the mod is installed straight away.
If there are dependencies, it will resolve them and show a dialog with a list of mods to install.
Resolving works like this:
1. Fetch dependencies for the package from ContentDB's API
2. For each hard dependency:
1. Check current game, exit if dep found
2. Check installed mods, exit if found
3. Check available mods from ContentDB:
1. Choose a package to install. Prefer higher scores and exact base name matches
(rather than modpacks).
2. Resolve dependencies for this package - ie, goto 1.
The ContentDB API is a dictionary of packages to dependencies.
The dictionary will allow ContentDB to prefetch dependencies without any client changes.
For example, say you request the dependencies for Mobs Monster.
It's pretty likely that the next request you'll make is for Mobs Redo, and so ContentDB can prevent
the need for another request by including the dependency information for Mobs Redo in the
response for Mobs Monster.
