typescript编译器api -如何检测属性类型是枚举还是对象

import * as ts from 'typescript';

const program = ts.createProgram(['file.ts'], {});
const typeChecker = program.getTypeChecker();

function getPropertyType(typeChecker: ts.TypeChecker, propertyName: string, typeName: string): string {
    const type = typeChecker.getTypeAtLocation(typeChecker.findModuleProperty(typeName, propertyName));
    return typeChecker.typeToString(type);
}

const propertyType = getPropertyType(typeChecker, 'property', 'ModuleName');
console.log(propertyType);

function isEnumType(typeChecker: ts.TypeChecker, propertyName: string, typeName: string): boolean {
    const type = typeChecker.getTypeAtLocation(typeChecker.findModuleProperty(typeName, propertyName));
    return ts.isUnionType(type) && type.types.every(t => t.flags === ts.TypeFlags.Enum);
}

const isEnum = isEnumType(typeChecker, 'property', 'ModuleName');
console.log(isEnum);
