};

Options

gleamToml

• Type: URL or String
• Default: "./gleam.toml"

File path or file URL to gleam.toml. If the value is relative path string, this plugin resolves the path from current working directory.

gleam({
	gleamToml: new URL("./gleam.toml", import.meta.url),
});

bin

• Type: String
• Default: "gleam"

Binary name or path to Gleam executable file. This plugin builds Gleam file using this value.

gleam({
	bin: "/path/to/gleam",
});
// > /path/to/gleam build --target javascript

buildOptions.warningAsErrors

• Type: Boolean
• Default: false

This option activates --warning-as-errors compiler flag. If this option is enabled, warning made by Gleam compiler will be treated as a build error.

gleam({
	buildOptions: {
		warningAsErrors: true,
	},
});

// This won't compile with the flag on, due to an unused variable warning.
pub fn hello(name: String) -> String {
  "Hello World!"
}
