MCLC (Minecraft Launcher Core) is a NodeJS solution for launching modded and vanilla Minecraft without having to download and format everything yourself.
PiMi (Minecraft Launcher Core) is a NodeJS solution for launching modded and vanilla Minecraft without having to download and format everything yourself.
Basically a core for your Electron or script based launchers.

#### Notes
##### Custom
If you are loading up a client outside of vanilla Minecraft or Forge (Optifine and for an example), you'll need to download the needed files yourself if you don't provide downloads url downloads like Forge and Fabric. If no version jar is specified, MCLC will default back to the normal MC jar so mods like Fabric work.

##### Installer
This runs an executable with specified launch arguments. Was used to support Forge 1.13 before ForgeWrapper.
##### Authentication
MCLC's authenticator module does not support Microsoft authentication. You will need to use a library like [MSMC](https://github.com/Hanro50/MSMC). If you want to create your own solution, the following is the authorization JSON object format.
