Rapid Development Environment (RDE) in AEM as a Cloud Service

Rapid Development Environment (RDE) in AEM as a Cloud Service is a new environment that you could include in your dev or prod instance on demand for quick deployment, this helps the AEM developers to quickly deploy the changes from local machine build just like we are doing package and bundle install using package manager.

Since AEM as CS package manage doesn't allow to deploy the code changes due to immutability of the system, but AEM as CS package manager allow to upload and install the content packages that includes paths like /content, /etc. 

Here, instead of using package manager for deployment RDE is using AppBuilder and pushing the locally build zip, jar files in AEM as CS RDE instance. Below are the detail about the Rapid Development Environment in AEM as CS development environment setup and uses of it.

How to setup Rapid Development Environment in AEM as CS?

1. First we need to enable the RDE instance for that you have to contact Adobe CSE/Support to get that enable under your license.

2. We need to install node and adobe cli to make the development setup and running in local machine.  

To enable and setup follow the steps given here: How to set up Rapid Development Environment | Adobe Experience Manager

How to use Rapid Development Environment in AEM as CS?

Using Rapid Development Environment is easy using adobe cli, for every task we have to just run one liner command on cli. To learn more and see the steps and action that is possible with RDE please follow the steps given in this document; How to use Rapid Development Environment | Adobe Experience Manager

Rapid Development Environment is going to make the developer life easy and this could be use by a developer at a time. Multiple developers could also use but that required very frequent sync between developers code. The biggest advantage of rapid development environment is that; we now use a full AEM as cloud service instance as a local. Where one can make the changes and deploy the code on cloud service without commit, and running the cloud manager CICD pipeline which taking approximately 40 minutes to make our code live on any AEM CS instance.

If you are seeing this error that means you are using any element that is either not imported or not getting resolved in your render.

Resolution 1

Check the elements that are being use and their import.

Resolution 2

Change the return statement and try to return without function sign. refere Stackoverflow | React.createElement: type is invalid -- expected a string

AppBuilder action

Could we use AppBuilder action from different AppBuilder application or service?

Adobe AppBuilder action in Adobe I/O runtime namespace is internal only, and could be use within the namespace until we expose them as a web-action. Once an Adobe I/O runtime action become web-action then, other users could use that from outside the namespaces just like an web service or internal action.
