| Minecraft Forge and FabricMC both have similar infrastructures: mod loaders, mod api, gradle build tools, deobuscation tools. | |
| Mod loader: supposed to just load mods in Minecraft and deobfuscate the game. | |
| Mod API: Offer events, loaders, hooks (e.g. model loading systems, config systems, standard energy API) | |
| Gradle build tool: The gradle plugin that is used to build mods | |
| Deobfuscation tool: Converts obfuscated Minecraft to deobfuscated ones so that modders can understand what they are modding | |
| Minecraft Forge: | |
| - Mod loader: Forge (more exactly, fmllauncher source set since 1.13, previously FML) | |
| - Mod API: Forge (previously Forge and part of FML) |

The character encodings currently supported by Node.js include:
'ascii' - For 7-bit ASCII data only. This encoding is fast and will strip the high bit if set.
'utf8' - Multibyte encoded Unicode characters. Many web pages and other document formats use UTF-8.
'utf16le' - 2 or 4 bytes, little-endian encoded Unicode characters. Surrogate pairs (U+10000 to U+10FFFF) are supported.
