Ecosystem tools

Jafa doesn't replace the standard Roblox open-source tooling — it scaffolds and wires it together. This page is a quick primer on each tool it installs and where it fits in, useful if you're new to the Roblox mono-repo ecosystem.

Rokit​

Rokit is a toolchain manager, similar in spirit to nvm or rustup. rokit.toml at the workspace root pins exact versions of every other tool below, and rokit install (run automatically by jafa init) downloads and installs them to match. Rokit itself has to already be on your PATH before running jafa init — see Installation.

Rojo​

Rojo syncs files on disk into the Roblox data model. Every project's default.project.json describes how its client/, server/, shared/, and ui/ folders map onto services like ReplicatedStorage and ServerScriptService — see Project structure. jafa build, jafa serve, and jafa sourcemap all shell out to rojo build, rojo serve, and rojo sourcemap respectively.

Wally​

Wally is the package manager for Roblox/Luau. There's one shared wally/wally.toml per workspace (not per project), so every project links to the same wally/Packages directory instead of installing its own copy. jafa init runs wally install --project-path ./wally once, during setup.

Selene & StyLua​

Selene is a Luau linter, StyLua is a Luau formatter. Both are installed via Rokit; Jafa scaffolds a selene.toml/stylua.toml per project so linting and formatting rules travel with the project.

Lune​

Lune is a standalone Luau runtime, installed via Rokit for running Luau scripts outside of Roblox Studio (for example, build or codegen scripts). Jafa installs it but doesn't invoke it directly — it's there for you to script against.

Mantle​

Mantle manages deploying and configuring Roblox experiences from a mantle.yml file — think of it as infrastructure-as-code for a Roblox place. jafa deploy builds the project, then generates/updates a per-environment mantle.yml and runs mantle deploy against it. See jafa deploy for the fields Jafa manages for you, and Mantle's own Authentication docs for one-time account setup Jafa doesn't handle.
