[QUESTION] What about TypeScript?

[Jacques Le Roux]

Hi,

I was reading https://www.thoughtworks.com/radar/languages-and-frameworks, for a long time I'm interested by TypeScript. This is what they say:

    *<<TypeScript <https://www.typescriptlang.org/>* is a carefully considered language and its consistently improving tools and IDE support continues
    to impress us. With a good repository <https://definitelytyped.org/> of TypeScript-type definitions, we benefit from all the rich JavaScript
    libraries while gaining type safety. This is particularly important as our browser-based code base continues to grow. The type safety in
    TypeScript lets you use IDEs and other tools to provide deeper context into your code and make changes and refactor code with safety. TypeScript,
    being a superset of JavaScript, and documentation and the community has helped ease the learning curve.>>

Has anybody considered using it? Should we not try it?

Thanks

Jacques

Try it where? How?

Hi Taher,

This Winter I began a try. But it was more complicated than I thought.

I worked on OfbizUtil.ts (from OfbizUtil.js).

I keep the work for now (was considering dropping it, but it's not a problem to keep it)

We use it on customer site, but I didn't work with it personally. I will
ask about it

Hello, personally i am a "fan" of typescript, but i've used it on other
project and not in a ofbiz context (hello i'am new).

TS is a not a full replacement to JS but help to do better code. The
learning curve is easy for a user of JVM langage (Java, Groovy, Kotlin)
or Dotnet.

The killing feature for myself is the capacity to use interface.

But is not perfect : you must convert TS to JS (ES5 or ES6) with build
tool, you must define a pipeline with tools like gulp, webpack etc.

Hi,

I am also relatively new to OFBiz, but it seems to me that Typescript is
a bit overkill : as Carl says we should defined a build step to
translate Typescript to Javascript but we should also define an install
step to get build dependencies to be able to develop on Typescript
files. I think all of these stuff will introduce more drawback than
benefits, especially regarding the total amount of javascript we write
on OFBiz

Thanks Guys,

Yes that's also the issues I crossed and mostly why I did not went further.

What I'd really like to have is using require.js. We have an issue (among somehow others related) for that: https://s.apache.org/8uj8v

i'm currently using Typescript in a project with OFbiz, but its in an
Angular 8 context. Using OFbiz as an AppServer only, I'm not using any
OFbiz widgets.  It's worth investing in Typescript if you intend to create
a whole new frontend.  Merging with existing OFbiz widgets is almost
impossible.
