As mentioned in the other answers  here and here  the cache can be cleared by using    templateCache removeAll      However as suggested by gatoatigrado in the comment  this only appears to work if the html template was served without any cache headers   So this works for me   In angular   app run    templateCache   function    templateCache          templateCache removeAll           You may be adding cache headers in a variety of ways but here are a couple of solutions that work for me   If using IIS  add this to your web config    lt location path  scripts app views  gt     lt system webServer gt       lt staticContent gt         lt clientCache cacheControlMode  DisableCache    gt       lt  staticContent gt     lt  system webServer gt   lt  location gt    If using Nginx  you can add this to your config   location     scripts app views        expires -1         Edit  I just realised that the question mentioned dev machine but hopefully this may still help somebody

There is no solution to prevent browser proxy caching since you cannot have the control on it   The other way to force fresh content to your users it to rename the HTML file  Exactly like https   www npmjs com package grunt-filerev does for assets

If you are using UI router then you can use a decorator and update  templateFactory service and append a query string parameter to templateUrl  and the browser will always load the new template from the server    function configureTemplateFactory  provide           Set a suffix outside the decorator function      var cacheBust   Date now   toString         function templateFactoryDecorator  delegate            var fromUrl   angular bind  delegate   delegate fromUrl            delegate fromUrl   function  url  params                if  url     null  amp  amp  angular isDefined url   amp  amp  angular isString url                     url     url indexOf          -1           amp                     url     v     cacheBust                             return fromUrl url  params                       return  delegate              provide decorator   templateFactory      delegate   templateFactoryDecorator       app config    provide   configureTemplateFactory      I am sure you can achieve the same result by decorating the  when  method in  routeProvider

For Development you can also deactivate the browser cache - In Chrome Dev Tools on the bottom right click on the gear and tick the option      Disable cache  while DevTools is open    Update  In Firefox there is the same option in Debugger -  Settings -  Advanced Section  checked for Version 33   Update 2  Although this option appears in Firefox some report it doesn t work  I suggest using firebug and following hadaytullah answer

If you are talking about cache that is been used for caching of templates without reloading whole page  then you can empty it by something like    controller  mainCtrl   function  scope   templateCache       scope clearCache   function           templateCache removeAll              And in markup    lt button ng-click  clearCache    gt Clear cache lt  button gt   And press this button to clear cache

I m posting this just to cover all possibilities since neither of the other solutions worked for me  they threw errors due angular-bootstrap template dependencies  among others    While you are developing debugging a specific template  you can ensure it always refreshes by included a timestamp in the path  like this           modal open                TODO  Only while dev debug  Remove later            templateUrl   core admin organizations modal-selector modal-selector html nd     Date now              controller   function   scope   modalInstance                 scope ok   function                     modalInstance close                                             Note the final  nd     Date now   in the templateUrl variable

I found that the HTTP interceptor method works pretty nicely  and allows additional flexibility  amp  control  Additionally  you can cache-bust for each production release by using a release hash as the buster variable    Here is what the dev cachebusting method looks like using Date   app factory  cachebustInjector   function conf           var cachebustInjector             request  function config                       new timestamp will be appended to each new partial  html request to prevent caching in a dev environment                            var buster   new Date   getTime                 if  config url indexOf  static angular templates    gt  -1                    config url       v    buster  join                                return config                       return cachebustInjector       app config    httpProvider   function  httpProvider         httpProvider interceptors push  cachebustInjector

As others have said  defeating caching completely for dev purposes can be done easily without changing code  use a browser setting or a plugin   Outside of dev  to defeat Angular template caching of route-based templates  remove the template URL from the cache during  routeChangeStart  or  stateChangeStart  for UI Router  as Shayan showed   However  that does NOT affect the caching of templates loaded by ng-include  because those templates are not loaded through the router   I wanted to be able to hotfix any template  including those loaded by ng-include  in production and have users receive the hotfix in their browser quickly  without having to reload the entire page  I m also not concerned about defeating HTTP caching for templates  The solution is to intercept every HTTP request that the app makes  ignore those that are not for my app s  html templates  then add a param to the template s URL that changes every minute  Note that the path-checking is specific to the path of your app s templates  To get a different interval  change the math for the param  or remove the   completely to get no caching      this defeats Angular s  templateCache on a 1-minute interval    as a side-effect it also defeats HTTP  browser  caching angular module  myApp   config function  httpProvider              httpProvider interceptors push function             return                request   function config                    config url   getTimeVersionedUrl config url                   return config                                        function getTimeVersionedUrl url               only do for html templates of this app            NOTE  the path to test for is app dependent          if   url    url indexOf  a app     lt  0    url indexOf   html    lt  0  return url             create a URL param that changes every minute            and add it intelligently to the template s previous url         var param    v        Date now     60000    10000     4 unique digits every minute         if  url indexOf       gt  0                if  url indexOf  v     gt  0  return url replace  v  0-9  4    param               return url     amp     param                    return url         param
