Bevy web platform
When to use
Load this when the same app should run in a browser. Packaging pipelines are not specified here.
ECS shape
- Features opened:
web(browser APIs, wasm32 only),webgl2(limitations so Wasm can use WebGL2),webgpu(overrides webgl2; Wasm with WebGPU only). - Asset note:
httpandhttpsfeatures enable remote asset download and warn about security.web_asset_cachecaches downloads and currently never invalidates entries. - Clipboard:
clipboard_imagesays it is not supported on WASM. - Window: the same
Windowcomponent still describes the canvas window. Check the window docs for DOM integration before writing it.
Coming from Godot
| Godot idea | Bevy idiom |
|---|---|
| HTML5 export | A wasm32 build with the web feature. Check the platform docs for toolchain steps before writing them. |
| WebGL vs WebGPU | webgl2 versus webgpu features. They conflict as documented. |
| Remote assets | http or https features. Security warning is on the feature list. |
Scope
- Check the web docs for wasm-bindgen, trunk, or other bundler steps before writing commands.
- Check the window docs for canvas sizing hooks before writing them.
Expert Knowledge Delta
Target: Bevy 0.20+.
Core ECS types: Component, Resource, Query, Commands, Startup, Update, Fixed / FixedMain (bevy::time), .chain(), Plugin, DefaultPlugins, MinimalPlugins. Messages and observers are an ownership slot. See bevy-events-messaging for their APIs. Systems run in parallel unless .chain() orders the ones that conflict.
Who owns state
| Piece | Owner | Who may mutate | Schedule |
|---|---|---|---|
| Data on one entity | Component | One system via Query | Update or FixedMain |
| One value for the whole app | Resource | One system | Startup to insert, then the schedule that reads it |
| Spawn | Commands | The spawning system | Startup for the initial world; later schedules for runtime spawn |
| Order that must not race | .chain() | The chained systems only | Same schedule |
| Plugin boundary | Plugin | build registers systems and resources | Before the app runs |
Borrow rule: two systems that both mutably query the same component must be ordered (.chain()) or split so only one writes. Unrelated systems stay parallel. That is the ECS page rule, not a guess at a system-set API.
Decision
| If you need | Do this | Do not |
|---|---|---|
| Per-entity data | Component + Query | A Godot node script |
| App-wide config or clock | Resource | Copy the value onto every entity |
| Stable simulation step | FixedMain and the Fixed clock | Tie simulation to raw frame Update |
| Startup spawn | Commands in Startup | Spawn from a render system |
| Cross-system notice that is not shared state | Message or observer slot in bevy-events-messaging | A new event type invented in this file |
| An API outside the documented set | Check the official docs first | A made-up crate or API |

NEVER
- Do not pin
/0.20.0/in docs URLs. WHY: links stay onlatest; the 0.20 target is stated once in prose. - Do not mutably query the same component from two unordered systems. WHY: the schedule runs systems in parallel unless
.chain()orders them. - Do not invent a physics, navigation, networking, or XR crate here. WHY: this skill only names documented Bevy crates and modules.
- No Godot HTML5 export preset names. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.
- No Godot types in Bevy code. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.
- No invented APIs or unnamed third-party crates as the chosen solver. WHY: Bevy code stays idiomatic ECS and uses only documented Bevy APIs.

docs.rs links use the unversioned latest permalink. The library pin on bevy-master stays 0.20.0.
