Making vanilla web-fontend (project with lit, web component) secured (discussions with chatGpt)

Query: I wn complete seperate .css/.scss and .html template file for my webcomponent.js like in angular. But with complete security. In lit. Use any js lib like domPurify, etc. But I wan complete safety. How? ChatGPT said: Thought for 16s Totally doable. Here’s a secure Lit setup with fully separate .html + .scss files , sanitized with DOMPurify , and rendered into the Shadow DOM without sacrificing performance. Folder layout src / lib/ safe- html .js components/ app-shell .html app-shell .scss app-shell .js 1) Install deps npm i dompurify npm i -D sass Vite will compile .scss . We’ll import the compiled CSS as text and attach it via adoptedStyleSheets (fast + memory-friendly). 2) app-shell.html (pure template file) Put your Carbon UI Shell markup here (no scripts). Example stub: < cds-header aria-label = "My App" > < cds-header-name prefix = "IBM" >[Platform] </ cds-header-name > < cds-header-glo...

Now after opening this conf file can be loaded like
1>M-x load-file <path_of_file>
2> Open this conf file in emacs n then M-x eval-buffer

You said: I am new to syslog in cpp programming n just starting. Can you teach me ChatGPT said: ChatGPT Sure! syslog is a standard for logging system messages in Unix-like operating systems. It provides a way to send log messages to the system log, which can then be collected and analyzed by various tools. Here's a basic guide to get you started with syslog in C++: 1. Include the Necessary Header To use syslog , you need to include the syslog.h header: cpp Copy code # include <syslog.h> 2. Open the Connection to syslog Before sending log messages, you need to open a connection to the syslog system. This is typically done at the start of your program: cpp Copy code openlog ( "your_program_name" , LOG_PID | LOG_CONS, LOG_USER); "your_program_name" : A string representing ...
