rbx-dom is a collection of cross-platform libraries that enables any software to interact with Roblox instances.
Documentation about the project is hosted at dom.rojo.space.
At this moment, we do not specify a MSRV for any project in rbx-dom. If you need to build one of these libraries with an outdated version of Rust, please open an issue explaining what blockers there are to you updating Cargo, what version you would need us to support, and why.
Weakly-typed Roblox DOM implementation. Defines types for representing instances and properties on them.
Contains Roblox's value types like Vector3
and NumberSequence
. Used by crates like rbx_dom_weak and a future rbx_dom_strong crate to let them share types and conversions.
Serializer and deserializer for for Roblox's XML model and place formats, rbxmx
and rbxlx
.
Serializer and deserializer for for Roblox's binary model and place formats, rbxm
and rbxl
.
Roblox reflection types for working with Instances in external tooling.
Bundled reflection database using types from rbx_reflection. Intended for users migrating from rbx_reflection 4.x and users who need reflection information statically.
Command line utility to generate a reflection database for rbx_dom_lua and rbx_reflection_database.
Command line utility to convert and debug Roblox model files.
Roblox Lua implementation of DOM APIs, allowing Instance reflection from inside Roblox. Uses a data format that's compatible with rbx_dom_weak to facilitate communication with applications outside Roblox about instances.

This project has unveiled a handful of interesting bugs and quirks in Roblox!
GuiMain.DisplayOrder
is uninitialized, so its default value isn't stableMaxPlayersInternal
andPreferredPlayersInternal
onPlayers
are scriptable and accessible by the command bar- Instantiating a
NetworkClient
will turn your edit session into a game client and stop you from sending HTTP requests ContentProvider.RequestQueueSize
is mistakenly marked as serializable- Trying to invoke
game:GetService("Studio")
causes a unique error:singleton Studio already exists
Color3
properties not serialized asColor3uint8
would have their colors mistakenly clamped in the XML place format. This was bad for properties onLighting
.ColorSequence
's XML serialization contains an extra value per keypoint that was intended to be used as an envelope value, but was never implemented.
Cutting new releases is not currently as optimized as it should be. While we work on improving it, packages need to be published in a specific order to make sense. The order that currently works well is:
rbx_types
rbx_dom_weak
andrbx_reflection
rbx_reflection_database
rbx_binary
andrbx_xml
The process for publishing these is:
- Decide a new version number, following SemVer
- Update changelog to list new release under its own heading
- Adjust versions of local dependencies to be the new release (this is why releases must happen in a specific order)
- Increment version in
Cargo.toml
- Add a git tag in the format
library_name-vMAJOR.MINOR.PATCH
at the commit that incremented the Cargo version - Publish to Cargo
