Deploy NodeJS application in Oracle Application Container Cloud


Check my previous blog regarding "How to create a NodeJS application for CRUD services on Oracle Database Cloud", I am going to use that application now to explain the deployment process on App Container Cloud.

As mentioned in the previous blog, you need "manifest.json". It should contain some basic config params. My case it contained :



For more info on these params : https://docs.oracle.com/cloud/latest/apaas_gs/DVCJV/GUID-D98FB882-5E58-4318-9DCB-4B404FD86E14.htm

You need to create a .zip file containing all the files and folders inside your NodeJS application :


IMPORTANT : Once you have the zip file, open it and go inside "node_modules" and delete "oracledb" folder from it.
Oracle Application Container Cloud provides this node_module out-of-the-box, so you don't need to include this in the packaging.

Now open service console of Application Container Cloud and click on "Create Application"



Then select "Node"



Give a name and upload your zip by choosing "Upload archive"



This will start the upload and deployment, which will take you to the Application's page and you can see the deployment progress log in the "Activity" section on the bottom of the page.

If it ran into deployment errors, download the deployment logs and check what went wrong, "how to" is here.

If everything goes alright your application will be deployed and will be active. You'll find the application URL in the top section of the page.



You can now check the apis via Postman :



Optionally, you can add your DB Cloud connection details as "Service Bindings" to the application. You need to go to "Deployment" section from the left-hand side and click on "Add" in Service Bindings section.





This will allow you to use "process.env.XXXX" variables in your NodeJS code, which will make the code transportable through different environments (dev, test, uat etc.).
Check in the previous blog : dbutils.js file where I have used these env variables.

That's it. You have now NodeJS application doing mirco CRUD services on DB cloud. A complete JS application for your Oracle DB instance.

Rich Text Editor - Oracle JET

Oracle JET has a lot of excellent UI components, but according to Murphy's law, client always comes up with something which you don't have at your disposal. So, driven by one of my client's requirements, I created a Rich Text Editor or WYSIWYG editor for Oracle JET. This is based on Quill JS and fully customizable. Github project download: https://github.com/sohamda/JET-Web-Components/tree/master/rich-text-editor I will explain in this blog, on how to integrate it in your own Oracle JET project. 1. Create and initialize your JET application and then put the downloaded web component inside "src\js\jet-composites" folder. 2. Once copied update your viewModel first. Add a snippet for passing the default content to be displayed by the editor after load. 3. Update view to load this editor Above you can see the "toolbar-options" property, that controls which options you should display to user on the editor. Those are basically the forma...

Exception Handling in ADF

This blog will give you an overview on how you can successfully deal with unhandled Runtime exceptions in an ADF application. This will give you an idea of: How to catch the unhandled exceptions. Write a separate log file with stacktrace and thread dumps. Redirect the user to an static error page #1. Catch unhandled exceptions :  Create a class "MyExceptionHandler" which extends : oracle.adf.view.rich.context.ExceptionHandler. Override handleException() method.     public void handleException(FacesContext facesContext, Throwable throwable, PhaseId phaseId) throws Throwable {         // this method is going to create a separate file with stacktrace and thread dumps         writeException(throwable);         // redirect to error page         redirectToErrorPage(facesContext);     }  Create a fo...

Chatbots and Oracle Cloud Services

Thanks to Oracle A-Team, I had a chance to work with Chatbots. 3 pure NodeJS applications, on couple of Oracle Cloud platforms and Facebook messenger, and my chatbot was running. Let me explain, the architecture a bit. To start with, following is the simple representation of how it works. Message Platform Server : Is a NodeJS application, deployed on Oracle Application Container cloud, acts as a channel between Facebook Messenger and the chatbot engine. It simply converts the incoming messages from Facebook and sends it to chatbot readable format. Also, when chatbot replies, it converts to Facebook readable formats and passes it to messenger. Chatbot Engine : Is a NodeJS application, which communicate with some REST APIs based on a conversation flow document and moves the flow of the conversation from one state to another. Flow JSON : Where we document, every state of a conversation and which APIs to call to generate a response. For example, at the beginning of the con...
