一、环境：
win10, vscode, LayaAirIDE2.6.0, nodejs v7.9.0(使用IDE相同的版本)

二、优势：
1、使用vscode编译项目
2、使用vscode定制gulp构建任务
3、脱离LayaAirIDE 编辑器独立编译
4、跨平台编译构建
5、使用LayaAirIDE node_modules库

三、laya项目文件夹下 .vscode/launch.json 添加配置

{
            "name":"compile",
			"type": "node",
			"request": "launch",
			//nodejs 可执行文件
			"runtimeExecutable": "D:\\workspace\\layabox\\node-v7.9.0-win-x64\\node.exe",
			//使用Laya编辑器下的 gulpjs
            "program": "D:\\workspace\\layabox\\LayaAirIDE_beta\\resources\\app\\node_modules\\gulp\\bin\\gulp.js",
            "args": [
				//使用Laya编辑器node_module
                "--cwd=D:\\workspace\\layabox\\LayaAirIDE_beta\\resources\\app",
                "--gulpfile=${workspaceFolder}/.laya/compile.js",
                "compile"
            ]
        }

四、laya项目文件夹下 .laya/compile.js 修改代码
1、修改ideModuleDir、workSpaceDir解析规则

//获取Node插件和工作路径
let ideModuleDir;
let workSpaceDir;
for(var argv of process.argv)
{
	if(argv.indexOf("--cwd=") == 0)
	{
		ideModuleDir = argv.split("=")[1] + "\\node_modules\\";
	}
	else if(argv.indexOf("--gulpfile=") == 0)
	{
		workSpaceDir = argv.split("=")[1].replace("/.laya/compile.js", "");
	}
}

2、修改typescript编译配置

typescript({
				cacheRoot:workSpaceDir + "/.rpt2_cache",
				tsconfig:workSpaceDir + "/tsconfig.json",
				check: true, //Set to false to avoid doing any diagnostic checks on the code
				tsconfigOverride:{compilerOptions:{removeComments: true}},
				include:/.*.ts/,
			}),

3、compile.js 完整代码如下

// v1.2.2
//获取Node插件和工作路径
let ideModuleDir;
let workSpaceDir;
for(var argv of process.argv)
{
	if(argv.indexOf("--cwd=") == 0)
	{
		ideModuleDir = argv.split("=")[1] + "\\node_modules\\";
	}
	else if(argv.indexOf("--gulpfile=") == 0)
	{
		workSpaceDir = argv.split("=")[1].replace("/.laya/compile.js", "");
	}
}

const gulp = require(ideModuleDir + "gulp");
const rollup = require(ideModuleDir + "rollup");
const typescript = require(ideModuleDir + 'rollup-plugin-typescript2');//typescript2 plugin
const glsl = require(ideModuleDir + 'rollup-plugin-glsl');
// 如果是发布时调用编译功能，增加prevTasks
let prevTasks = "";
if (global.publish) {
	prevTasks = ["loadConfig"];
}

gulp.task("compile", prevTasks, function () {
	// 发布时调用编译功能，判断是否点击了编译选项
	if (global.publish && !global.config.compile) {
		return;
	} else if (global.publish && global.config.compile) {
		// 发布时调用编译，workSpaceDir使用publish.js里的变量
		workSpaceDir = global.workSpaceDir;
	}

	return rollup.rollup({
		input: workSpaceDir + '/src/Main.ts',
		onwarn:(waring,warn)=>{
			if(waring.code == "CIRCULAR_DEPENDENCY"){
				console.log("warnning Circular dependency:");
				console.log(waring);
			}
		},
		treeshake: false, //建议忽略
		plugins: [
			typescript({
				cacheRoot:workSpaceDir + "/.rpt2_cache",
				tsconfig:workSpaceDir + "/tsconfig.json",
				check: true, //Set to false to avoid doing any diagnostic checks on the code
				tsconfigOverride:{compilerOptions:{removeComments: true}},
				include:/.*.ts/,
			}),
			glsl({
				// By default, everything gets included
				include: /.*(.glsl|.vs|.fs)$/,
				sourceMap: false,
				compress:false
			}),
			/*terser({
				output: {
				},
				numWorkers:1,//Amount of workers to spawn. Defaults to the number of CPUs minus 1
				sourcemap: false
			})*/        
		]
	}).then(bundle => {
		return bundle.write({
			file: workSpaceDir + '/bin/js/bundle.js',
			format: 'iife',
			name: 'laya',
			sourcemap: false
		});
	}).catch(err=>{
			console.log(err);
	})
});

五、完成以上步骤配置，即可脱离layaIDE而使用vscode编译项目了^_^
