在自定义LanguageServiceHost中引用.d.ts文件

我正在实现将频繁调用的Typescript编译器，并且需要快速编译单个Typescript文件。我遵循本指南设置内存编译器：http://blog.scottlogic.com/2015/01/20/typescript-compiler-api.html。我正在编译的TS文件有几个像jQuery这样的东西，我有TSD文件的导入。在自定义LanguageServiceHost中引用.d.ts文件

typescriptCompile.ts

import * as fs from 'fs'; 
import * as path from 'path'; 
import * as ts from 'typescript'; 

class MyLanguageServiceHost implements ts.LanguageServiceHost { 
    files: { [fileName: string]: { file: ts.IScriptSnapshot; ver: number } } = {}; 

    log = _ => { }; 
    trace = _ => { }; 
    error = _ => { }; 
    getCompilationSettings = ts.getDefaultCompilerOptions; 
    getScriptIsOpen = _ => true; 
    getCurrentDirectory =() => ""; 
    getDefaultLibFileName = _ => "lib"; 

    getScriptVersion = fileName => this.files[fileName].ver.toString(); 
    getScriptSnapshot = fileName => this.files[fileName].file; 

    getScriptFileNames(): string[] { 
     var names: string[] = []; 
     for (var name in this.files) { 
      if (this.files.hasOwnProperty(name)) { 
       names.push(name); 
      } 
     } 
     return names; 
    } 

    addFile(fileName: string, body: string) { 
     var snap = ts.ScriptSnapshot.fromString(body); 
     snap.getChangeRange = _ => undefined; 
     var existing = this.files[fileName]; 
     if (existing) { 
      this.files[fileName].ver++; 
      this.files[fileName].file = snap 
     } else { 
      this.files[fileName] = { ver: 1, file: snap }; 
     } 
    } 
} 

var host = new MyLanguageServiceHost(); 
var languageService = ts.createLanguageService(host, ts.createDocumentRegistry()); 

const includeFiles = [ 
    'es6-promise.d.ts', 
    'jquery-3.1.1.d.ts', 
    'twemoji-2.2.4.d.ts' 
]; 

includeFiles.forEach(file => host.addFile('types/' + file, fs.readFileSync(path.join(__dirname, 'types', file)).toString())); 

export function compile(code: string) { 
    host.addFile(`code.ts`, code); 

    var output = languageService.getEmitOutput("code.ts").outputFiles[0].text; 

    console.log(output); 
}

代码编译

import * as twemoji from 'twemoji-2.2.4'; 

export const test = twemoji.parse('test');

语言服务引发错误试图访问脚本twemoji-2.2.4.ts而非twemoji-2.2.4.ts。我如何使用语言服务/编译器注册定义？

我已经部分找到了足以覆盖我的用例的答案。我已经添加了以下到MyLanguageServiceHost：

resolveModuleNames = (moduleNames: string[], containingFile: string): ts.ResolvedModule[] => { 
    return moduleNames.map(name => { 
     return { 
      resolvedFileName: name + '.d.ts', 
     } 
    }); 
};

这解决了他们的.d.ts形式的所有模块这正是我需要的。如果混合使用定义和源文件，我仍然不确定如何处理这个问题。
