Upgrading to Angular 8 and NgRx 8

Overview

Do you have an awesome application written with Angular v7 using NgRx v7, but have been feeling left out will all the mentions online and at conferences about Angular v8 and NgRx v8? Well you are in luck! Today we will explore together, how to upgrade our applications to use Angular v8 using the Angular CLI tooling. We will also explore upgrading to NgRx v8. This will allow us to take advantage of the new features provided in NgRx v8. Included with NgRx v8 is a shiny set of creators, or type-safe factory functions, for actions, effects, and reducers.

Upgrading Dependencies

Upgrading Angular

The Angular team has provided a great website that walks through the process of upgrading in-depth. This website can be found at Angular Update Tool. We will touch on some of the information today.

Building Evolutionary Architectures

Chapter 1 - Software Architecture

Architecture is 'the important stuff, whatever that is' or 'the parts that are hard to change later'. An architect analyzes business, domain, and other requirements to develop solutions that satisfy a list of prioritized architectural characteristics (-ilities). We should consider time and change with respect to architecture, or evolvability.

Software ecosystems are in a state of dynamic equilibrium. New languages, tools, methods constant force new equilibriums to emerge (free OS, linux, + free operations, puppet, led to the shift to containers). The pace of change in technology is constantly and rapidly changing in unexpected ways. We should architect systems knowing the landscape will change. Make ease of change a principal of architecture, remove the 'hard to change' definition of architecture.

An evolutionary architecture supports guided, incremental change across multiple dimensions. Evolvability is a meta characteristic that

Purpose

Follow the steps below if you are interested in creating your own custom configurable Couchbase docker image. You will start off with the official Couchbase Enterprise docker image that is available on Docker Hub and use the Couchbase CLI and REST interface to create a custom configurable image.

Credits

This approach inspired by the tutorial. We essentially built a custom docker image from the base Coucbase server image that is configured for our development needs!

Steps

Create a new file named DockerFile and open it using an editor of your choice
Now add the following lines to the DockerFile.

From Oracle: If Table Exists:

The best and most efficient way is to catch the "table not found" exception: this avoids the overhead of checking if the table exists twice; and doesn't suffer from the problem that if the DROP fails for some other reason (that might be important) the exception is still raised to the caller:

BEGIN
   EXECUTE IMMEDIATE 'DROP TABLE mytable';
EXCEPTION
   WHEN OTHERS THEN
      IF SQLCODE != -942 THEN
