Examples

The CLI makes it easier to build, run, and lint examples by automatically enabling examples’ required features. Take Bevy’s web_asset example, for instance. It requires the https feature in Cargo.toml:

[[example]]
name = "web_asset"
path = "examples/asset/web_asset.rs"
required-features = ["https"]

Running cargo build --example web_asset will fail with Cargo complaining that the https feature was not enabled. The Bevy CLI improves this situation by automatically enabling the feature for you:

# The CLI will automatically add `--feature https`, as that feature is required to run the example.
bevy build --example web_asset

# It also works when building and running for the web.
bevy run --example web_asset web

The CLI will automatically enable required features for examples when you run bevy build, bevy run, and bevy lint. Note that it will only do so when you build a specific example using the --example flag. If you try to build all examples with --examples, the CLI will not do anything extra.
