102 ColdBox Tips and Ticks by Luis Majano

How to make your code easier to read and manage with ColdBox?

ColdBox gives you powerful ways to build cleaner, more maintainable code, especially when dealing with query strings. In this tip, we’ll explore how to pass a struct into the buildLink() method, making your code easier to read and manage.


Using a Struct for Query Strings

Instead of manually crafting query strings like this:

<a href="users.editor?id=3&format=plain">My Link</a>

You can let ColdBox do the work for you! By passing a struct to the queryString argument of the buildLink() method, ColdBox will automatically convert it into a properly formatted query string. It makes your code more readable and easier to maintain.

Here’s an example:


<a href="#event.buildLink( 'users.editor', { id:3, format:'plain' } )">
My Link</a>

ColdBox will flatten the struct into the query string ?id=3&format=plain for you. It’s cleaner, easier to read, and less error-prone than manually concatenating strings.


Why Use a Struct for Query Strings?


  • Cleaner code: Using structs keeps your links more organized and reduces the clutter of inline query strings.
  • Easier maintenance: You can quickly add or remove parameters from the struct without having to worry about formatting the query string manually.
  • Flexibility: ColdBox handles the conversion for you, so you can focus on writing code instead of worrying about URL structure.

Give it a try in your next project, and see how much cleaner your code can be! Stay tuned for more tips and tricks to boost your ColdBox development.

BoxLang 1.17 Series Part 4 : WriteDump Enhanced!

You call writeDump() on an ORM entity or a very rich class graph . The browser locks up. Thirty seconds later you get a page with forty thousand rows on it, you scroll for a while, you give up, and you go edit your code to dump a sub-key instead. Or worse, you crash the server.

BoxLang AI 3.4 Blog Series Part 4 : Locking Down Prompt Injection

LLM applications face a class of attack traditional input validation was never built for: prompt injection. An attacker embeds instructions in user input, a retrieved document, a web page your tool fetched, or an MCP result, trying to override your system prompt, exfiltrate data, or hijack a tool call. BoxLang AI 3.4.0 ships four layered, configurable defenses against exactly this, plus one more that's on unconditionally.
