Just Enough Resources (JER) is a utility mod that adds resource-focused JEI integration for dungeon loot, mob and plant drops, villager trades, enchantment details, and world generation data for Minecraft on Fabric, Forge, and NeoForge. It is designed as an addon workflow for players who want faster in-game planning with fewer external lookups.
If you have ever paused your game to search wiki pages for where an ore spawns, what a villager can trade, or which chest can roll a specific item, this mod targets exactly that friction. The just enough resources (jer) mod extends JEI with contextual data that turns guesswork into planning, so your sessions feel more intentional and less trial-and-error. With 4,900,440 downloads on Modrinth (effectively close to five million), it has clear social proof from a large player base that relies on this information-first style of modded Minecraft.
Key Features of Just Enough Resources (JER)
- Dungeon chest loot — This helps you see where loot can come from before you commit time to exploration. In practical play, that means fewer random cave dives and better route planning when you are hunting for a specific progression item. It is especially useful in modpacks where chest tables matter for early momentum.
- Enchantment information — Enchanting can be expensive, so having clearer information reduces wasted levels and books. When you understand enchantment context inside your normal JEI flow, it becomes easier to decide whether to invest now or wait for a better setup. That keeps mid-game upgrades more controlled and less RNG-frustrating.
- Mob drops — Knowing drop sources directly in your interface changes how you design farms and mob encounters. Instead of farming blindly, you can target specific mobs with a purpose and shorten grind loops. For survival players, this often translates into faster gear, potion, or crafting progression.
- Plant and seed drops — Crop and seed information is easy to underestimate, but it affects food chains, breeding setups, and renewable material loops. This feature makes it easier to pick which plants are worth scaling first in your world. The result is a cleaner path from early survival to stable resource production.
- Villager trades — Villager progression becomes much easier when trade options are visible and comparable in one place. You can decide sooner which professions to level and which workstations are worth your base space. That saves both emeralds and time, especially in economies built around specific enchanted books or materials.
- World generation information — Ore and resource location planning is one of the biggest time sinks in modern Minecraft. World-gen visibility gives you a more informed mining strategy, so branch mining and biome travel feel purposeful. It also helps multiplayer teams coordinate who gathers what and where.
- Create your own ore graphs (RegionScanner support) — JER's workflow can be extended by creating your own graphs with RegionScanner, giving advanced players more control over resource analysis. This is valuable when you want world-specific data rather than broad assumptions. If you enjoy optimization, this feature pushes the mod from "handy" to genuinely strategic.

How to Install Just Enough Resources (JER)
- Choose your mod loader first: Fabric Mod Loader, Minecraft Forge, or NeoForge.
- Match your Minecraft version to an available JER build (for example 1.21.1, 1.20.1, 1.19.4, 1.19.3, or 1.19.2 in the listed download groups).
- Confirm JEI is present in your setup, because JER is built as a JEI addon rather than a standalone replacement.
- Place the JER jar in your game's
modsfolder for the same profile and loader instance you launch. - Start Minecraft and verify JER content appears in your JEI workflow, then test loot, trade, or world-gen views in a test world before long-term play.

Yes — those three loaders are listed as supported mod types for this project. You should still match the correct file to your exact Minecraft version and loader branch before launching.
Can I use this mod on Minecraft 1.21.11?
Yes — 1.21.11 is included in the listed Minecraft versions. As with any modded setup, verify your full pack versions are aligned before assuming cross-mod compatibility.
Is this mod useful if I mainly care about villager progression?
Yes — villager trade visibility is one of the key features. It helps you make better profession and base-layout decisions earlier, which can reduce wasted emeralds and setup time.
What changed in the most recent update?
