If you have been developing Lightning Components for a while it is probable that you have come up against the feared Locker Service. If you are aware of Summer 18 Locker Service changes, you will know that, luckily, Locker Service restrictions have been relaxed. However, there are still some libraries that are considered unsafe and that cannot run within this context. For those cases, lightning:container comes to the rescue!
Passing action handlers to child components using Aura.Action
Last week I discovered something about Lightning Components I didn’t know about: aura:action. This is an attribute type that you can use to pass actions to a child component, in addition to the other supported attribute types, and it can be specially helpful if you want to decide at component instantiation which actions should the child component perform.

Controlling record level security with Sharing
As next week I will give a talk about security at London’s Calling, I would like to create a blog post series regarding to Salesforce security for developers. I already talked about CRUD and FLS in a previous post so I thought it was a good idea to continue with sharing.
Sharing is the common way of referring to record level security in the platform, this is, the settings that control if a user X will have read (&report) / write / transfer / delete / share permissions for a specific record Y.

Analyzing Big Objects data
Following with the blogs I have recently written about Big Objects, as this one or this one, I want to finish this blog series for now talking about one use case that I am sure you have thought about when reading the previous posts.
Imagine that you have some Big Objects in your organization. You have stored some data there, and now, you want to report on them. As you probably know if you read this post, search, reports and dashboards are not available for Big Objects. How can we accomplish this?
Big Object field types workarounds
If you have taken a look at Big Objects, you will have noticed that we can only create fields of the following types (information valid for Winter 18 release):
- Text
- Number
- Datetime
- Lookup to Standard or Custom objects
Big Objects can be used for multiple purposes, but typically, archiving old records is one of the use cases. What can you do if you need to archive a custom object which has field types that are not supported, as for example picklist or master-detail? What if you want to create lookups to Big Objects? Read this post and you will find a solution.
