# Objective - Contributes to #15460 - Supersedes #8520 - Fixes #4906 ## Solution - Added a new `web` feature to `bevy`, and several of its crates. - Enabled new `web` feature automatically within crates without `no_std` support. ## Testing - `cargo build --no-default-features --target wasm32v1-none` --- ## Migration Guide When using Bevy crates which _don't_ automatically enable the `web` feature, please enable it when building for the browser. ## Notes - I added [`cfg_if`](https://crates.io/crates/cfg-if) to help manage some of the feature gate gore that this extra feature introduces. It's still pretty ugly, but I think much easier to read. - Certain `wasm` targets (e.g., [wasm32-wasip1](https://doc.rust-lang.org/nightly/rustc/platform-support/wasm32-wasip1.html#wasm32-wasip1)) provide an incomplete implementation for `std`. I have not tested these platforms, but I suspect Bevy's liberal use of usually unsupported features (e.g., threading) will cause these targets to fail. As such, consider `wasm32-unknown-unknown` as the only `wasm` platform with support from Bevy for `std`. All others likely will need to be treated as `no_std` platforms. |
