Re: AngularJS

It's a while since I looked at any other frameworks, but the thing about
Angular is that it tries to be a more or less completely integrated
framework, including almost everything you need to create scalable,
enterprise class web applications. It also includes all of the build
tooling you need as well as tools to help quickly scaffold apps from
scratch and scaffold new parts of the app for you, saving you from having
to write much of the boiler-plate code yourself. Some of the other
frameworks are much lighter, and superficially easier to learn perhaps, but
might not contain some of the functionality you will later need later down
the line when you want to write more than just a relatively basic app.

Another benefit IMO of Angular is that you're pretty much forced to use
Typescript instead of plain old Javascript, which helps avoid many, many
gotchas. Angular is also very opinionated, so you're corralled into doing
things the Angular way, I found this beneficial because it saves any
headaches and arguments other things like naming conventions and folder
structures, which are all already decided for you.

There's a tutorial on the Angular website here https://angular.io/start
One of my favourite learning resources is the Angular University
https://angular-university.io/course/getting-started-with-angular2, it's
not all free but the beginner's course is if you sign up by the look of it.
Here's another free course from another guy whose videos I like
https://www.youtube.com/watch?v=AaNZBrP26LQ Bear in mind, Angular is on
version 12 now and so some things in these tutorials might be slightly out
of date but the fundamentals are the same.

Another great resource is Stackblitz https://stackblitz.com/ here you can
almost instantly spin up a working Angular app and play around with it,
it's also available for several other languages and frameworks. Here's a
video that demonstrates just how powerful Stackblitz is, this was from 3
years ago, the latest version is even better!

Have you across a good tutorial for Angular?

A friend of mine just sent over a decent one for EmberJS. Doesn't look as
powerful though.

...it's probably unfortunate that you found AngularJS and not Angular

and wasted your time with that. The learning curve is steep but Angular is
easier and faster to get started with and Single Page Web-apps are, IMO,
definitely better than the alternative. Maybe give it another try later 🙂
I have used it for quite a few years so can maybe help if you get stuck.

I went with Angular as a trial.

In the last 20-minutes or so, I've decided it was a waste of time and

the existing CGIDEV2 will stay as is.

You definitely shouldn't be using AngularJS, it's long since been

deprecated by Angular (no JS), which is now some 12 versions further on
than the original. It's also alot nicer to use and with its CLI, you can
get a skeleton project up and running quite quickly, although after that,
the learning curve is steep!

Subject: [WEB400] AngularJS

I'm using AngularJS to replace a CGIDEV2 application. So far, it is

not working out with the time I've wasted on it.

The $http post doesn't want to pass parms to the RPGLE routines. I can

see the routine trying, but the POST variables aren't there.

I have the following:
var data = {
pagectl:"LOGIN",
pagesub1:"VALIDATE",
username: username,
password: password
};
var config= {
headers: {"Content-Type": "application/json"}
};
$http( { url:'/cgi-bin/wqa0100c',
method:"POST",
headers: {"Content-Type": "application/json"},
data: data
}
)
.success(function(response) {
console.log(response);
if( response.status=="OK" ) {
smn=response.smn;
slname=response.name;
} else {
$rootScope.error=response.errmsg;
}
});

The data isn't seen by the RPGLE routine. I can call it from the

webbrowser and pass parameters as a GET process, no issue.

The same chunk of code is running in production now with the CGIDEV2

processes and is access via AJAX.

Any ideas?
