TypeScript编译器API函数，可以检查类是否实现了接口

import * as ts from "typescript";

// 创建一个TypeScript编译器的类型检查器
const program = ts.createProgram(["path/to/your/file.ts"], {});
const checker = program.getTypeChecker();

// 获取要检查的类的节点
const sourceFile = program.getSourceFile("path/to/your/file.ts");
const classNode = findClassNode(sourceFile, "YourClass");

// 检查类是否实现了接口
const implementsInterface = ts.implementsClauseElement(classNode, checker);

if (implementsInterface) {
  console.log("YourClass implements the interface.");
} else {
  console.log("YourClass does not implement the interface.");
}

// 辅助函数，用于在AST中查找类节点
function findClassNode(node: ts.Node, className: string): ts.ClassDeclaration | undefined {
  if (ts.isClassDeclaration(node) && node.name && node.name.text === className) {
    return node;
  }

  return node.forEachChild(childNode => findClassNode(childNode, className));
}
