javascript - can not get MAP to work within system.config packages for SystemJS -

hello have following config set systemjs:

    system.config({     packages: {         //sets root path of angular2 app         'desktopmodules/regentdms/app': {             //module format expected in application, register = system.register or system.registerdynamic compatibility module format             format: 'register',             //default file extension paths             defaultextension: 'js',             map: {'./app' : './desktopmodules/regentdms/app'}         },     }    });  system.import('app/boot')         .then(null, console.error.bind(console)); 

the default extension works fine 404 error in console says:

get http://localhost:81/app/boot 404 (not found)

but if change following:

    system.config({     packages: {         //sets root path of angular2 app         'desktopmodules/regentdms/app': {             //module format expected in application, register = system.register or system.registerdynamic compatibility module format             format: 'register',             //default file extension paths             defaultextension: 'js'         },     }    });  system.import('/desktopmodules/regentdms/app/boot.js')         .then(null, console.error.bind(console)); 

then work.

question:

how can set map setting can use short hand app/ refer absolute path of desktopmodules/regentdms/app in import statements app/boot (meaning desktopmodules/regentdms/app/boot.js)

thanks

edit #1:

so changed ./app app suggested , tried both of following:

 map: { 'app': './desktopmodules/regentdms/app' }  map: { app: './desktopmodules/regentdms/app' } 

and not work when using of following import statements:

system.import('app/boot')  system.import('./app/boot') 

i following error both:

http://localhost:81/app/boot 404 (not found)

solution:

move map declaration config object so:

    system.config({     packages: {         //sets root path of angular2 app         'desktopmodules/regentdms/app': {             //module format expected in application, register = system.register or system.registerdynamic compatibility module format             format: 'register',             //default file extension paths             defaultextension: 'js'         }     },     map: { 'app': './desktopmodules/regentdms/app' }   });  system.import('app/boot')         .then(null, console.error.bind(console)); 

as @langley suggested in comment, should use app, not ./app (name not path), , move map definitions packages object config object.

the map option ... allows map module alias location or package:
