@typescript-eslint/project-service

用于 linting 的独立 TypeScript 项目服务封装器 ✨

¥Standalone TypeScript project service wrapper for linting ✨

typescript-eslint 项目服务是 TypeScript "项目服务" API 的封装器。VS Code 等编辑器使用这些 API 以编程方式 "open" 文件并生成 TypeScript 程序以获取类型信息。

¥The typescript-eslint Project Service is a wrapper around TypeScript's "project service" APIs. These APIs are what editors such as VS Code use to programmatically "open" files and generate TypeScript programs for type information.

import { createProjectService } from '@typescript-eslint/project-service';

const filePathAbsolute = '/path/to/your/project/index.ts';
const { service } = createProjectService();

service.openClientFile(filePathAbsolute);

const scriptInfo = service.getScriptInfo(filePathAbsolute)!;
const program = service
  .getDefaultProjectForFile(scriptInfo.fileName, true)!
  .getLanguageService(true)
  .getProgram()!;
