Fallback
by Modcafe
Fallback is a Fabric library mod for datapack developers, offering a logger, date formatting, dialogs and a math API that other mods and packs can call.
What it does
Fallback bundles several shared helpers that Modcafe's data packs draw on. LoggerAPI writes problems to the log, and an in-game chat logger reports them using DateAPI. DateAPI provides the local date and time in several formats, and RandomDialogAPI shows random dialogs that a player does not see twice in a row.
The mod is described as a work in progress, and some pieces are still incomplete, including a math API that the author marks as unfinished. The author plans to expand the library over time and make it more accessible to other people. Modpacks that include Fallback can ship Fallback datapacks, and configuration screens are among the features aimed at datapack developers.
Fallback runs on the server alone, so players join without installing it. It requires Fabric API, and Mod Menu is optional. Files are published for Fabric only, for 26.2 and 26.3, with 1.3.0 for 26.3 as the latest file. The mod is released under a custom license and is not open source, though its source code, issue tracker and wiki are public.
Key features
Shared datapack helpers
Helper code shared by Modcafe's data packs, so datapack developers can reuse common functions.
Logger with in-game chat output
LoggerAPI records problems in the log, and a chat logger can show them in game with timestamps.
Date and time formats
DateAPI supplies the local date and time in a number of formats for scripts and messages.
Random dialogs
RandomDialogAPI shows dialogs chosen at random, avoiding repeats for the same player.

Use cases
Datapack scripting
Datapack authors can call the logger, date and dialog helpers instead of writing their own.
Modpack builds
Modpack makers can include Fallback and its datapacks as shared building blocks.
Who it’s for: Datapack developers and modpack authors who want shared logging, date and dialog helpers on a server. Players without datapacks that use the library have no reason to install it.
