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

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...

libzip, libcurl, libwebsockets, jansson json, gsl what other good libraries in C? ChatGPT said: ChatGPT Here’s a list of other useful libraries in C, categorized by their purpose, that can complement the ones you mentioned: 1. Networking and Protocols libuv : A multi-platform asynchronous I/O library, used for network operations and file system interactions. Powers Node.js. asio : While more known in C++, it has a C API for network programming (TCP, UDP, etc.). libevent : Provides asynchronous event notification for network services and supports multi-threading. ZeroMQ : High-performance asynchronous messaging library for building scalable distributed systems. 2. Compression and Archiving zlib : A popular and highly efficient compression library. bzip2 : Another compression library, focused on higher compression ratios than zlib . LZ4 : An extremely fast compression library, optimized for speed rather than compression ratio. zstd (Zstandard) : A fast and efficient compression algorithm...

C/C++ Postgres libpq execute query with params chatGpt example

PGresult *PQexecParams(PGconn *conn, const char *command, int nParams, const Oid *paramTypes, const char * const *paramValues, const int *paramLengths, const int *paramFormats, int resultFormat); give example ChatGPT said: ChatGPT Here’s a basic example demonstrating how to use PQexecParams in C++ to execute a parameterized query in PostgreSQL. Example: Inserting Data Using PQexecParams Let's assume we are inserting a row into a table called users with the following columns: id (integer) name (text) age (integer) cpp Copy code # include <iostream> # include <libpq-fe.h> # include <memory> # include <string> void checkResult (PGresult* res, PGconn* conn) { if ( PQresultStatus (res) != PGRES_COMMAND_OK) { std::cerr << "Execution failed: " << PQerrorMe...
