Spread the word

Share your thoughts

Today I was getting ready to send a file from my app to the browser for the user to download.  I was all set to use cfcontent to do this, but knowing ColdBox I thought I would do a quick check to see if the framework had any nice convenience methods for me to use to make life easier and sure enough... sendFile() in the core Utilities plugin.


So, this post is just a quick word of advice.  Don't reinvent the wheel.  If you are doing something, anything common, check the docs and see if ColdBox can do it for you.  You will be amazed at whats available in the core plugin set already for you to use.  

Plug it In

Plug IT IN

Here are just a few I use commonly.

ORMService - generic ORM Service helper for Hibernate
QueryHelper - all sorts of goodies in here, sorting queries is one of my favorite. Or the querySim.
Validator - all sorts of standard validation methods here. checkEmail and checkIPAddress are my favorites.
FileUtils - This is a utilities library that are file related. Lots of fun methods here.
Utilities - A good mix of a variety of handy methods, like todays gem sendFile()

I wonder why sendFile() is inside Utilities and not FileUtils.

We are still refactoring our utilities so soon they should all be in the correct locations

Hello, Do you have an example where I can see how to use getPlugin("Utilities").sendFile(file="test.txt").

Alexadra, That is all there is to it, just call the getPlugin("Utilities").sendFile(file="test.txt"). The test.text can be change to a relative path to any file you which to send to the users browser for download. One thing to note though is that this was refactored in to the fileUtils plugin. getPlugin("FileUtils").sendFile(file="test.txt"); Thanks, Curt
