TypeScript

[roybatty28]

I agree with Dhugal. We are(were?) evaluating Sencha for a big project and that a seemingly official representative of Sencha was making those dismissive comments is disturbing and bad for Sencha's business.

Whether people like it or not, Coffescript, Typescript, and a whole bunch of other languages that compile down to Javascript are not going away. If COBOL was the only game in town for the browser, we'd be compiling down to that too.

If Sencha embraces these other languages, then they're more likely to not lose business when other toolkits come out for Typescript.

As a member of a large dev team using Sencha Touch, I think TypeScript could help us out a lot in identifying problems before runtime.

I found a project on Github that generate typescript definitions for ExtJS. I dont know if its working already.
https://github.com/zz9pa/extjsTypescript

I made some modifications (fork) of this project:
https://github.com/andremussche/extjsTypescript

Also made a ready to use typescript file:
https://github.com/andremussche/extj...xt-4.1.1a.d.ts

This is my first result, don't know if it really works runtime, but at least I get no compiler errors anymore .
Maybe the documentation can be added to. (so you can get JS documentation text in Visual Studio).

Well done. I tried learn ruby to extend JSDuck, but a I gave up. Its a nice idea to load files as json in .NET. I will try to generate a Ext3.4 definition.

Anybody come up with a way to use Ext JS in Visual Studio (with intellisense and error checking)?

Thankyou for this, looking at your code now.

I have already written a few 1000 lines of non ExtJS TypeScript code, it is utterly brilliant and marks a new software epoch for me.

Come on Sencha you do not have a spare year to think about TypeScript, it is happening right now, look at all the JavaScript libraries already converted for TypeScript:

Sencha is noticeable by its absence, please don't become the North Korea of JavaScript frameworks e.g. isolated and convinced of its own greatness.

Absolutely!

I'm using the holidays to try switching my code over to TS. I'm going to try the GitHub def files.

That's an impressive list for sure.

I also find the "ugly" term a little offensive as one must understand that Typescript is an attempt to add type to a totally unstructured little language that took 2 weeks to write! Intellisense is just one part of the problem as one of really painfull aspects of Javascript is that typos can cause the developer to waste so much time. Any tool that can help in this area is an asset to me and especially given that the architect of the compiler is Anders Hejlsberg, the architect of C#.

Now I also like the "improvements" that Sencha has been adding to JS but Typescript is a huge step above these. I am also playing with Typescript support for Ext and hope that we can find a solution. Sencha would be foolish to not look at this impressive tool that could change how Javascript is written.
