Fields

import_not_used_as_values: ImportsNotUsedAsValues

use_define_for_class_fields: bool

Align the semantics of TS class fields with TC39 class fields. Defaults to false.

See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#the-usedefineforclassfields-flag-and-the-declare-property-modifier.

When running tsc with configuration "target": "ESNext", "useDefineForClassFields": true, TS class fields are preserved as JS class fields. We target ESNext, so this our behavior with use_define_for_class_fields: true.

When running tsc with configuration "target": "<ES6-ES2020>", "useDefineForClassFields": true, TS class fields are transformed to Object.defineProperty() statements. You must additionally apply the swc_ecmascript::transforms::compat::es2020::class_properties() pass to get this backward-compatible output.

no_empty_export: bool

Don’t create export {}. By default, strip creates export {} for modules to preserve module context.
