The article discusses Cross-Origin Resource Sharing (CORS), a security mechanism that restricts how resources on a web page can be accessed by scripts from different origins. It emphasizes the importance of understanding CORS when developing APIs, particularly with BoxLang, to ensure that client-side JavaScript can successfully access resources. The author highlights the ease of creating APIs in BoxLang, noting that all methods marked as remote are automatically exposed for access, provided the appropriate CORS headers are configured in the response to prevent blocking of requests by browsers.
"CORS is a security feature in browsers that checks whether one domain can access resources from another, typically through preflight requests to verify permissions."
"When building APIs, especially in BoxLang, it's crucial to implement the right CORS headers to allow client-side JavaScript to access your resources without being blocked."
