Developer Function: Server Script: Debug
## Overview
Describes how to line debug "[Server Script](/en/manual/table-management-server-script)" using Visual Studio Code.
## Limitations
1. During debugging, the script will pause midway until the debugger connects, making the table unavailable. Do not use this in a production environment.
## Prerequisites
1. Port 9222 must be open on the server where Pleasanter is running.
1. Visual Studio Code must be installed on the PC used for debugging.
## Operation Procedure
1. Create an arbitrary working folder. *Here we will use the work folder.
1. Create a .vscode folder inside the working folder.
1. Create a launch.json file inside the .vscode folder.
1. Launch Visual Studio Code and open the work folder. *When the work folder is opened in Visual Studio Code, the left side EXPLORER will look like this:
1. Change the address in launch.json to the server address.
1. Access Pleasanter in a browser and add //debug// to the first line of the "[Server Script](/en/manual/table-management-server-script)" you want to debug, then save it.
1. Open the "[Table](/en/manual/table)" you want to debug. The server script will be in debug mode and standby, with no response on the screen.
1. In Visual Studio Code, select Run → Start Debugging.
1. The source code is loaded into Visual Studio Code and line debugging is enabled.
## launch.json
This file contains the connection information to the Pleasanter environment to be debugged. Change the address as needed. If Pleasanter is on the local PC, specify localhost.
##### JSON
```
{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to ClearScript V8 on port 9222",
"type": "node",
"request": "attach",
"protocol": "inspector",
"address": "192.168.1.101",
"port": 9222
}
]
}
```
## Example Debug Script
By adding //debug// at the beginning, the script will pause when executed, allowing for debugging. Remove //debug// when not debugging. In the server script example below, the context.Log() method outputs logs to the console in the browser's developer tools.
##### JavaScript
```
//debug//
if (context.UserId === 1) {
context.Log('User ID is 1');
} else {
context.Log('User ID is not 1');
}
```
