Nodejs in Visual Studio Code 10.IISNode

1. Start

Nodejs in Visual Studio Code 08.iis:http://www.cnblogs.com/mengkzhaoyun/p/5410185.html

Refer to this article to deploy a iisnode example

2. Deploying the node. JS Express Framework sample program in Iisnode

• Create an Express sample program

$ cd D:\Libraries\Documents\Visual Studio code$ express myapp  Create:myappcreate:myapp/package.json  ... Install dependencies:> CD MyApp && npm installrun the app:> SET debug=myapp:* & npm Start

• Create a MyApp directory in IIS to publish this node program
  • Application Pools: DefaultAppPool (IIS default,. Net integration)

• Create a Web. config file to the MyApp directory
  • Note that the startup program for Node Express is the bin/www file

<configuration>  <system.webServer>    <!--bin/www is the Express sample default startup program--    
 
 

  
  
 
   
The 404 error will appear when you open address http://localhost/myapp/in the browser 
    
 
     
The reason is that the bin directory is the default output directory and does not allow module calls by default
 
    
 
  
 
 
HTTP error 404.8-not found the request filtering module is configured to reject the path in the URL that contains the Hiddensegment section.
 
 

  
  
 
   
In the MyApp directory, create a new index.js to try to resolve this issue
 
  
 
 
Cut the bin/www code and delete the bin/www, and modify the portal in Web. config to Index.js
<configuration>  <system.webServer>    <!--Index.js is the start-up program for MyApp--    
 
  

  
   
 
    
Browse http://localhost/myapp/at this time, a run-time error occurs 
     
 
      
This run-time error indicates that node in the execution of the Index.js process error, is a relative address written wrong problem,node finally executed, not easy ah, probably because I will bin/www hard copy come over to forget to fix the relative directory. 
 
     
 
   
 
  
Iisnode encountered an error when processing the request.  Hresult:0x2http status:500http substatus:1002http reason:internal Server erroryou is receiving this HTTP response Because system.webserver/iisnode/@devErrorsEnabled configuration setting is ' true '. In addition to the log of stdout and stderr of the Node.exe process, consider using debugging and ETW traces to further di Agnose the problem. The last 64k of the output generated by the Node.exe process to stderr are shown below:application have thrown an uncaught E Xception and is terminated:Error:Cannot find module '. /app ' at Function.module._resolvefilename (module.js:325:15) @ function.module._load (module.js:276:25) at Modul E.require (MODULE.JS:353:17) at require (internal/module.js:12:17) at object.<anonymous> (D:\Libraries\Documen Ts\visual Studio code\myapp\index.js:7:11) at Module._compile (module.js:409:26) at object.module._extensions.

Modify Index.js 
     
 
      
.. /app changed to./app a little bit less, you see?
 
     
 
   
 
  
var app = require ('./app '); var debug = require (' Debug ') (' myapp:server '); var http = require (' http ');
 
  

  
   
 
    
re-visit, error cannot find module ' Serve-favicon ' , careless forgot npm install ... 
 
    
Execute cmd command NPM install dependency package for MyApp
 
    
Re-visit webpage http://localhost/myapp/, 404 Not Found appears 
     
 
      
Virtual path error, need to modify virtual path in App.js
 
     
 
   
 
  
Not found404error:not Found @ D:\Libraries\Documents\Visual Studio code\myapp\app.js:30:13 at Layer.handle [as Han Dle_request] (D:\Libraries\Documents\Visual Studio code\myapp\node_modules\express\lib\router\layer.js:95:5) at Trim_prefix (D:\Libraries\Documents\Visual Studio code\myapp\node_modules\express\lib\router\index.js:312:13) at D : \libraries\documents\visual Studio Code\myapp\node_modules\express\lib\router\index.js:280:7 at Function.process_ params (D:\Libraries\Documents\Visual Studio code\myapp\node_modules\express\lib\router\index.js:330:12) at Next (D : \libraries\documents\visual Studio code\myapp\node_modules\express\lib\router\index.js:271:10) at D:\Libraries\ Documents\Visual Studio code\myapp\node_modules\express\lib\router\index.js:618:15 at Next (D:\Libraries\Documents\ Visual Studio code\myapp\node_modules\express\lib\router\index.js:256:14) at Function.handle (D:\Libraries\ Documents\Visual Studio code\myapp\node_modules\express\lib\router\iNdex.js:176:3) at router (D:\Libraries\Documents\Visual Studio code\myapp\node_modules\express\lib\router\index.js : 46:12)
 
  

  
   
 
    
Modify App.js, Note that the release path is MyApp, finally see Welcome to express not easy ah, don't forget to change the path of the public directory
 
   
 
  
App.use ('/myapp ', Express.static (Path.join (__dirname, ' public ')); App.use ('/myapp ', routes); App.use ('/myapp/users ', users);
 
  

  
   
 
    
To modify the Views/layout.jade, note that there is a relative path to the CSS, minus the front slash
 
   
 
  
DOCTYPE htmlhtml  head    title= title    link (rel= ' stylesheet ', href= ' stylesheets/style.css ')  body    block Content

 
  

  
   
 
    
Open Http://localhost/myapp/index.js/debug remote debugging in Chrome, an error, or a pattern. 
     
 
      
It seems that this index.js/debug connection was executed by the app ...
 
      
So far, all errors have been completely impossible to debug, relying on my (wo) (shi) Feng (CAI) Rich (DE)
 
     
 
   
 
  

 
  

  
   
 
    
The cause of the above error is urlrewriter configuration
 
   
 
  
All the execution requests under the MyApp are given to Index.js to execute, obviously myapp/index.js/debug this address should not give index.js to execute.
Modify the URL rewriter section in Web. config to set index.js/debug this address to a mismatch negate= "true".
<configuration>  <system.webServer>
<!--Index.js is the start-up program of MyApp--

 
   

  
    
 
     
Finally see Node Inspector, enter Http://localhost/myapp/users,Node in the browser inspector will capture this processing
 
    
 
   
3. Summary
Iisnode a variety of diao, support after the release of cross-platform remote debugging, if the release process encountered problems how to do it, Iisnode released 5 years (currently 0.2.* version), should have accumulated a lot of issues, an article turned to see, or to ask the author to solve it.
