In VS Code, there are two core debugging modes, Launch and Attach.

1. Starting in the browser
   • When you open DevTools in a browser, you are attaching DevTools to the open browser tab.
2. Starting in the code editor
   • The editor launches your process, and it automatically attaches its debugger to the newly launched process.

References:

• https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations

A configuration file allows you to configure and save debugging setup details.

VS Code keeps debugging configuration information in a launch.json file located in a .vscode folder in your workspace (project root folder)

1. ng --version (or ng v)

2. Open Developer Tools in the browser. Under the 'Elements' tab, look for html/body/app-root[ng-version]

3. To render the Angular version on a page, import VERSION from @angular/cli.

const version = VERSION.full;

$top & $skip: The $top system query option requests the number of items in the queried collection to be included in the result. The $skip query option requests the number of items in the queried collection that are to be skipped and not included in the result.

serviceRoot/People?$top=2

$expand: The $expand system query option specifies the related resources to be included in line with retrieved resources.

Marks a test method as being a data theory.

Data theories are tests which are fed various bits of data from a data source, mapping to parameters on the test method.

If the data source contains multiple rows, then the test method is executed multiple times (once with each data row). Data is provided by attributes which derive from Xunit.Sdk.DataAttribute:

• Xunit.InlineDataAttribute
• Xunit.MemberDataAttribute

The Content-Disposition response-header field has been proposed as a means for the origin server to suggest a default filename if the user requests that the content is saved to a file.

Example:

Content-Disposition: attachment; filename="fname.csv"

Note: In the context of a CORS request, use the Access-Control-Expose-Headers Http header to expose Content-Disposition as a header value.

References:

https://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html

All CORS related headers are prefixed with "Access-Control-".

Access-Control-Allow-Origin
Access-Control-Allow-Credentials
Access-Control-Expose-Headers

Security information and event management (SIEM) software products and services combine security information management (SIM) and security event management (SEM). They provide real-time analysis of security alerts generated by applications and network hardware.

Vendors sell SIEM as software, as appliances or as managed services; these products are also used to log security data and generate reports for compliance purposes.
