So you broke the code. Now what?
Here are some tricks on how we debug B2B Commerce:
Backend Debugging (Apex classes)
ccLog, for general API extensions debugging
You can use the querystring
ccLog with the token value you assign on CCAdmin to have the output from both the managed package and your customizations directly into your browser console. Check out the official Cloudcraze Logging for more details (I personally think that page is a bit dated, but should work).
TL;DR: write something like this in your code:
//... some code ... ccrz.ccLog.log(LoggingLevel.DEBUG,'SOME_DEBUG_IDENTIFIER',valueToDebug); //... more code ...
And then when checking the storefront, add
&ccLog=SOME_LOGGING_TOKEN to the URL, where the logging token is the same as the one that was set in ccAdmin.
Apex debugging, for more granular or non-B2B Commerce debugging
This is how you would normally do it for any salesforce code, but this is only useful for custom code and extensions: Managed package code debug logs won't be visible.
System.debug logs won't show the output from the managed package. For those cases, you'll have to rely on the OOTB cclogs or log a support ticket.
Front-end Debugging (VF pages, handlebars, js)
CSR Flow, for Configuration Settings
With CSR flow, instead of using the regular community's "friendlier" URL, your page will use the apex route (you'll see
/apex in the URL). When using this routing approach instead of showing the generic community error page, it will show you the apex page, with the exception message (if any). This technique has been very useful to track missing configuration settings.
}} , for Backbone models
}} in your handlebars template to debug the model being fed into it. In my opinion, this is less stressful than trying to deal with the cloudcraze models (at least until someone creates a guide on the models available for the templates 😉 ). More info here.
Browser Inspector/Developer Tools, for everything else
In general Salesforce Support/Salesforce B2B Commerce services teams have been supportive for Front end issues, but your mileage may vary. Consider staying within their backbone + handlebars + visualforce pages architecture if your team is not very experienced yet.
If still stuck...
If debugging is not enough, and you still can't figure out then consider getting help.
