Json Assets for Stardew Valley

What this mod does

Json Assets (JA), by spacechase0, is one of the oldest frameworks in Stardew Valley: according to Nexus, more than 1,000 mods use it. It lets content packs add new content to the game without any coding, using only text files. On its own it does nothing.

What packs can add

• Crops (including giant ones) and fruit trees.
• Items, craftable big objects and cooking or crafting recipes.
• Hats, clothing, boots and weapons.

Requirements and compatibility

It needs SMAPI, SpaceCore and Expanded Preconditions Utility. Version 1.11.11 (October 18, 2025, 165 KB) is for 1.6.14 and includes fixes by Elizabeth. The page says it works on Windows, macOS and Linux, in single-player and multiplayer, and the Nexus tag marks it as compatible with Android.

Since 1.6, Content Patcher can add items directly, so many newer mods no longer require it. Only install it if a mod needs it: each mod’s requirements list will tell you. Before uninstalling it, the author asks you to remove the content it added from your game, so you don’t leave broken items in your save.

Requirements

• Stardew Valley 1.6.14 or later (Windows, macOS or Linux; tagged as compatible with Android)
• SMAPI 4.x
• SpaceCore and Expanded Preconditions Utility
• Content packs that use it (it does nothing on its own)

How to install it

1. Install SMAPI, SpaceCore and Expanded Preconditions Utility first (see their mod pages) and launch the game once with SMAPI.
2. Open the Json Assets page on Nexus Mods, go to the Files tab and click Manual download on the main file (Json Assets 1.11.11). You need a free Nexus account to download.
3. Extract the .zip outside the game folder and move the resulting folder into the Mods folder, inside the game folder.
4. Copy the Json Assets content packs you want to use into the same Mods folder and launch the game with SMAPI.
