Re: Hosting a Large Number of Node Apps on the IBM i

But what exactly do you mean when you contrast a vanilla CRUD app with a

better user experience?

The below article is a CRUD app I wrote in Node.js. CRUD apps are mostly
for traversing the database relationships. For example, display customers,
select specific customer, select customer orders, display specific order.

In contrast, a non-CRUD app would bring you to a dashboard showing the
latest orders, the orders with issues, customers with outstanding money
issues, etc. In short, non-CRUD apps incorporate many DB2 tables and
business logic into a single screen to keep the user efficient. CRUD apps
are more for allowing you to maintain data on a table by table, screen by
screen, basis.

That's my view of CRUD. I am sure there are many other flavors of views.

Aaron,

When I think of CRUD, I simply thing of operations against a database
table. A RESTful service can perform create, read, update and delete
operations against a table with no user interface defined.

When I hear the phrase CRUD app, I think of a green screen that allows you
to take some options against records in a display file. I know I don't want
to develop web pages and mobile apps that resemble green screens. I could
just use a screen scraper to do that--and then have users wonder why we
switched from green screens, and why my web pages don't work like the web
pages they view on the Internet. I get this.

But what exactly do you mean when you contrast a vanilla CRUD app with a

I can understand the need for generated REST services (great for Javascript
front-ends) but was surprised to hear you espouse CRUD. In my experience
the vanilla CRUD apps (even for internal use) are losing ground (as they
should) because a better experience is being demanded by both customers
and employees. I think this is where WebSockets are really going to shine.

Are others still seeing CRUD apps as acceptable (from the
customer/employee perspective)?

you never know what you run into, my web-systems runs side by side
with a varity of products.

btw, I am able to publish 600 tables with the same amount of generic
REST/CRUD services in less than 5 minutes by using my SDK - how long
do you think it will take to hand build the same in node.js?

Soon after you make the move to Web interfaces, you won't be
constrained

to

only supporting "employees". Most shops branch out to supporting

customers,

trading partners, and providing greater variety of Web services
across

more

application areas.
