Starcounter/Starcounter

Starcounter is a fusion of your C# VM and a ACID RAM DBMS

@pal88

no no..... run application /projects/files in command line tool....

Per Samuelsson

@per-samuelsson

well, sorry i dont think i understand exactly what it is you want to do :worried:

the server console you see is a machine-wide "service" that you can consider some kind of controller of all apps and databases on your machine

you never access that server directly, if thats what you mean

starcounter is about writing applications that expose themselves to the outside via REST interfaces (normally), i.e. the Handle.GET for example

pal88

@pal88

ok... so i tried running example files in command line/command prompt... it said file not found for all files... so i thought may be we can access it in the starcounter server command prompt...... sorry for confusing...

for the examples where we have accepting parameters in the examples like squaring a number.... error SCERR6066- an unhandled,unidentified nonstarcounter execption occurs

Per Samuelsson

@per-samuelsson

hi pal88

can u provide the code that fails with 6066-error? its hard to help you solve this without seeing the code

pal88

@pal88

using System;
using Starcounter;

namespace example4
{
class Hello
{
static void Main()
{
Handle.GET("/squared?{?}", (int x) =>
{
return "<!DOCTYPE html><title>Hello</title>" + x + " squared equals " + x * x;
});
}
}

}

it runs now but gives error" URI not found: GET /example4 "

when tried to open it in a browser...

Per Samuelsson

@per-samuelsson

" GET /example4" is the wrong string, you should to "localhost:8080/squared" to invoke it

pal88

@pal88

tried that as well still says the same thing...:(

it says resource not found..

Per Samuelsson

@per-samuelsson

maybe you are not formatting it correctly? are you providing a number to be squared for example?

pal88

@pal88

should not the number be given at run time

Per Samuelsson

@per-samuelsson

localhost:8080/squared?10

yes, it should, its a parameter in the call to your handler

pal88

@pal88

oh i dint know that....thanks..

Per Samuelsson

@per-samuelsson

if u define your handler like u have done in the code above, you should invoke it (from a browser for example, or using curl) like this: localhost:8080/squared?100

pal88

@pal88

im sorry may be i dint understand the tutorial properly....it should have been beginner friendly...

thanks for your patience... @per-samuelsson

@per-samuelsson

sure, no problem! we are here to help :hand:

hi pal88

no, not to my knowledge

maybe @dan31 knows?

Per Samuelsson

@per-samuelsson

pal88

@pal88

pal88

@pal88

hi @per-samuelsson

i need to plot graphs using data acquired on a regular basis...

for eg - like plotting a graph of temperature variations over a week/month

Per Samuelsson

@per-samuelsson

i will forward this and see if someone can help u out

Marcin Warpechowski

@warpech

from the server side, you need to expose the data as a JSON array

and then on the client, you just bind to the data, preferably using a Web Component or some JavaScript charting library

Ivar Bergman

@ivarbergman

Hi! What is the recommended way to get the Location value (in Javascript)? I need to create a xhr call to a Handle, and thus need to set the Referer headers. Is there some method/property on the Puppet object I can use to fetch the Location value?

Ivar Bergman

@ivarbergman

I think I found it. Can you confirm that this seems like a OK way to pass the session/location in a xhr call:

xhr.setRequestHeader('X-Referer', puppet.network.remoteUrl.pathname);

Per Samuelsson

@per-samuelsson

hi @ivarbergman

sorry, this is totally not my area, I'll see if I can find someone that can pop in and comment on your findings :sparkles:

Tomek Wytrębowicz

@tomalec

Hi @ivarbergman , do you really need to make very custom XHR? there is a puppet.network.send method

Per Samuelsson

@per-samuelsson

thanks tomalec :+1:

Tomek Wytrębowicz

@tomalec

.send will take care on versioning, OT and all that stuff for you

in other case puppet.network.remoteUrl seems good way to go, but we have not tested it that way, and probably you will need to handle versioning manually

Ivar Bergman

@ivarbergman

Thanks! I will take a look at .send
