Struct deno_ast::EmitOptions

pub struct EmitOptions {
    pub emit_metadata: bool,
    pub imports_not_used_as_values: ImportsNotUsedAsValues,
    pub inline_source_map: bool,

}

Options which can be adjusted when transpiling a module.

This implements Hash so the CLI can use it to bust the emit cache.

Fields

emit_metadata: bool

When emitting a legacy decorator, also emit experimental decorator meta data. Defaults to false.

imports_not_used_as_values: ImportsNotUsedAsValues

What to do with import statements that only import types i.e. whether to remove them (Remove), keep them as side-effect imports (Preserve) or error (Error). Defaults to Remove.

inline_source_map: bool

Should the source map be inlined in the emitted code file, or provided as a separate file. Defaults to true.

inline_sources: bool

Should the sources be inlined in the source map. Defaults to true.

jsx_automatic: bool

true if the program should use an implicit JSX import source/the “new” JSX transforms.

jsx_development: bool

If JSX is automatic, if it is in development mode, meaning that it should import jsx-dev-runtime and transform JSX using jsxDEV import from the JSX import source as well as provide additional debug information to the JSX factory.

jsx_factory: String

When transforming JSX, what value should be used for the JSX factory. Defaults to React.createElement.

jsx_fragment_factory: String

When transforming JSX, what value should be used for the JSX fragment factory. Defaults to React.Fragment.

jsx_import_source: Option<String>

The string module specifier to implicitly import JSX factories from when transpiling JSX.

source_map: bool

Should a corresponding .map file be created for the output. This should be false if inline_source_map is true. Defaults to false.

transform_jsx: bool

Should JSX be transformed. Defaults to true.

var_decl_imports: bool

Should import declarations be transformed to variable declarations using a dynamic import. This is useful for import & export declaration support in script contexts such as the Deno REPL. Defaults to false.
