sapui5 - When to use jQuery.sap.registerModulePath() with an example? -


hi have tried reading sapui5 documentation above not able understand usage. difference between sap.ui.localresources() , jquery.sap.registermodulepath() , when use what?

if can explain easy example helpful. can use jquery.sap.registermodulepath() load mockdata?

if using resourceroots either in bootstrap config or in app descriptor, you've been using jquery.sap.registermodulepath time each key-value pair, defined in resourceroots, passed arguments static method.

for example, may have in index.html: 

data-sap-ui-resourceroots='{   "my.app": "./" }'

ui5 registers namespace ("my.app") globally reference saying "whenever name mentioned while resolving other module names, should target module in registered path ("./") relative current document.location.href.".

the above code same calling jquery.sap.registermodulepath("my.app", "./") directly.

  • here, can pass user-defined url prefix. e.g.: "../" instead of "./" needed if project has *.html file in one hierarchy level deeper such mockserver.html
  • if we've module in deeper hierarchy, e.g. in custom/control/somewhere/c3/chart/, can register namespace: "my.app.c3chart": "./custom/control/somewhere/c3/chart" ,
    • use shortcut example in xmlview definition:
      xmlns:c3="my.app.c3chart" instead of xmlns:c3="my.app.custom.control.somewhere.c3.chart".
    • reduce maintenance costs changing registered path when module file changes hierarchy level. namespace "my.app.c3chart" can still used everywhere.
  • if project not huge, hardly need call jquery.sap.registermodulepath directly.

what difference between sap.ui.localresources() , jquery.sap.registermodulepath()?

here current source code of sap.ui.localresources does:

sap.ui.localresources = function(snamespace) {   jquery.sap.registermodulepath(snamespace, "./" + snamespace.replace(/\./g, "/")); };

that's it. calls jquery.sap.registermodulepath right away dots in namespace (if any) replaced "/".

  • we can't pass user-defined url prefix
  • the namespace tightly coupled actual folder hierarchy , name.
  • sap discourages usage of api (for non-stand-alone apps).
  • the api reference mentions api become obsolete.

to honest, don't know when i'd favor sap.ui.localresources on resourceroots.

feel free leave comment if not clear or if has example sap.ui.localresources.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
