Coldbox and VueJS untangled

Customize your resource routing in Coldbox

In this post I will show you how coldbox can help you creating resourceful routes, how cbswagger shows me that I don’t want the defaults resource() routing method, and how easy it is to create your own method!

If you want to create a REST API in coldbox, you often need to create a lot of routes for this API. So let’s say you want to create endpoints to list, view, update, create and delete a User resource. Following the coldbox manual, I need to implement the following routes:

Configuring SES URL’s on apache and the Coldbox router.

Often when we deploy a coldbox website we fire up commandbox, create a webserver and put NGINX in front to route our application requests to the correct lucee instance. We never experienced any problems when configuring search engine safe (SES) url’s. Just to remind you: instead of writing this

https://mysite.nl/index.cfm?event=myhandler.myaction

we can rewrite this to something more friendly such as

https://mysite4u.nl/myhandler/myaction

So we proxy our request via Nginx to a lucee coldbox application and use some rewrite rules as described in the coldbox manual. Recently we had a slightly different configuration: apache in front of an old-fashioned standard lucee standard install on Linux. Again, we followed instructions in the same coldbox manual but NO success…

Event.buildLink: query params vs path variables

I had some issues with how event.buildlink() in Coldbox is generating a URL. To understand what’s my problem let me introduce the old-fashioned way to hit a coldbox application

http://mysite.ext/index.cfm?event=user&age=30
or
http://mysite.ext/index.cfm?event=user.index&age=30

With some rewrite magic this last form can be written as

http://mysite.ext/user/index&age=30
or even
http://mysite.ext/user/index/age/30

So all four forms are behaving the same, if you apply the correct rewrite rules in your webserver and the default rules in the Coldbox router. The coldbox manual has some info on rewrites for several webservers. So in most cases the web is rewriting your url’s in such a format that coldbox will receive this:

http://mysite.ext/index.cfm?user/index/age/30

Coldbox itself is smart enough to hand this over to the router, which has some default rules enabled which translate the user/index/age/30 to:

  • event = user.index
  • age=30

Cfcookie or cookieStorage?

Coldbox has the cbstorages module which can be used as an API for accessing persistent storage such as cookie, session, application, cache and more. The question is: why should I use such storage if there is cfcookie or something simple as as session struct?

Let me explain with some code. I was working on updating the cbi18n module where we can use session, client, cookie or request scope to store the currently selected locale. In code this is getting ugly soon, with code like this

switch(instance.localeStorage){
  case "session" : { storage = session; break; }
  case "client"  : { storage = client; break;  }
  case "cookie"  : { storage = cookie; break;  }
  case "request" : { storage = request; break; }
}

and in other places in the code:

<!--- Storage of the Locale in the user storage --->
<cfif instance.localeStorage eq "session">
  <cfset session.DefaultLocale = arguments.locale>
<cfelseif instance.localeStorage eq "client">
  <cfset client.DefaultLocale = arguments.locale>
<cfelseif instance.localeStorage eq "request">
  <cfset request.DefaultLocale = arguments.locale>
<cfelse>
  <cfcookie name="DefaultLocale" value="#arguments.locale#" />
</cfif>

Using bCrypt in cbsecurity

In a previous post I explained why bCrypt is a good choice for hashing your passwords. In this post I will show were you can hash and check your passwords: in your handlers, in a service layer or in some entity model. When using cbsecurity I will show you why it fits best in your service layer or entity model.

But let’s start with some hashing and checking in a handler. Make sure bcrypt is installed by using commandbox and execute the command:

box install bcrypt

Let’s say you want to store your password in a db table. Bcrypt has two important methods for hashing and checking called hashPassword() and checkPassword() but you have to call them on a bcrypt instance, so you can inject bcrypt in a handler:

property name="bCrypt" inject="BCrypt@BCrypt";

or getting your instance directly by calling getInstance("BCrypt@BCrypt"). But you don’t have to do this, by installing the module some mixin helpers are created so you can just call bCryptHash() or bCryptCheck(). These handy functions will be available in all handlers, views, layouts or even interceptors. So let’s say we want to save a user in some handler it will look like this:
