Treelib is a library of typescript made for Warcraft 3 v1.32+. It requires the map to be set to LUA as typescript compiles to lua.
It's built for TSTL and not intended to work with other tooling currently.
There is an NPM package of it here: https://www.npmjs.com/package/wc3-treelib
https://trello.com/b/wdLuUlL3/treelib Here is my internal kanban board, its readonly but occasionally i set up things i want to add there. You can find me primarily in the Hive workshop discord: https://discord.hiveworkshop.com/
Use a wc3 template like https://github.com/cipherxof/wc3-ts-template and then add "wc3-treelib" as a devDependency.
npm install the dependencies.
Go into your tsconfig.json and add "wc3-treelib" to the "types" array.
You can now use all TreeLib functionality and hopefully get autocomplete in your IDE.
