In your Business Central workspace some configuration files were created and an example AL file (see part 3). In this post we will get into more detail about the configuration files (JSON based).
The AL workspace contains configuration files:
- launch.json
- In this file serveral settings are defined like: servername, server instance and startupobject.
- Located in the .vscode folder
- Controls debug environment
- app.json
- This configuration file serves as a manifest and contains information about your app.
- Located in the workspace root
An example how the file launch.json looks like by default in BC16:
{
"version": "0.2.0",
"configurations": [
{
"type": "al",
"request": "launch",
"name": "Your own server",
"server": "http://localhost",
"serverInstance": "BC160",
"authentication": "Windows",
"startupObjectId": 22,
"startupObjectType": "Page",
"breakOnError": true,
"launchBrowser": true,
"enableLongRunningSqlStatements": true,
"enableSqlInformationDebugger": true
}
]
}
Some more important launch.json settings explained:
