I know I can set a timeout each and every time:

$http.get(\'path/to/service\', {timeout: 5000});

... but I want to set a global timeout to

    I've the same requirement and I m using AngularJS 1.0.7. I've come up with the below code as none of the above solutions seems feasible for me (feasible in the sense I want timeout to be global at one place). Basically, I m masking the original $http methods and adding timeout for each $http request and overriding other shortcut methods, like get, post, ... so that they'll use the new masked $http.

    JSFiddle for below code:

    /**
     * @name ngx$httpTimeoutModule
     * @description Decorates AngularJS $http service to set timeout for each
     * Ajax request.
     * 
     * Implementation notes: replace this with correct approach, once migrated to Angular 1.1.5+

    ;(function () {
        'use strict';
    
        var ngx$httpTimeoutModule = angular.module('ngx$httpTimeoutModule', []);
    
        ngx$httpTimeoutModule.provider('ngx$httpTimeout', function () {
            var self = this;
            this.config = {
                timeout: 1000 // default - 1 sec, in millis
            };
    
            this.$get = function () {
                return {
                    config: self.config
                };
            };
        });
    
        /** 
         * AngularJS $http service decorator to add timeout
         */
        ngx$httpTimeoutModule.config(['$provide',  function($provide) {
    
            // configure $http provider to convert 'PUT', 'DELETE' methods to 'POST' requests
            $provide.decorator('$http', ['$delegate', 'ngx$httpTimeout', function($http, ngx$httpTimeout) {
                // create function which overrides $http function
    
                var _$http = $http;
    
                $http = function (config) {
                    config.timeout = ngx$httpTimeout.config.timeout;
                    return _$http(config);
                };
                $http.pendingRequests = _$http.pendingRequests;
                $http.defaults = _$http.defaults;
    
                // code copied from angular.js $HttpProvider function
                createShortMethods('get', 'delete', 'head', 'jsonp');
                createShortMethodsWithData('post', 'put');
    
                function createShortMethods(names) {
                    angular.forEach(arguments, function(name) {
                        $http[name] = function(url, config) {
                            return $http(angular.extend(config || {}, {
                                method : name,
                                url : url
                            }));
                        };
                    });
                }
    
                function createShortMethodsWithData(name) {
                    angular.forEach(arguments, function(name) {
                        $http[name] = function(url, data, config) {
                            return $http(angular.extend(config || {}, {
                                method : name,
                                url : url,
                                data : data
                            }));
                        };
                    });
                }
    
                return $http;
            }]);
    
        }]);
    
    })();
    

    Add dependency on the above module, and configure the timeout by configuring ngx$httpTimeoutProvider, like below:

    angular.module('App', ['ngx$httpTimeoutModule']).config([ 'ngx$httpTimeoutProvider', function(ngx$httpTimeoutProvider) {
        // config timeout for $http requests
        ngx$httpTimeoutProvider.config.timeout = 300000; // 5min (5 min * 60 sec * 1000 millis)
    
    } ]);

    This is possible with bleeding-edge angular.js (tested with git master 4ae46814ff).

    You can use request http interceptor. Like this.

     angular.module('yourapp')
      .factory('timeoutHttpIntercept', function ($rootScope, $q) {
        return {
          'request': function(config) {
            config.timeout = 10000;
            return config;
          }
        };
     });
    

    And then in .config inject $httpProvider and do this:

    $httpProvider.interceptors.push('timeoutHttpIntercept');

    UPDATED: $http will not respect default setting for timeout set it in httpProvider (see the comments). Possible workaround: https://gist.github.com/adnan-i/5014277

    Original answer:

    angular.module('MyApp', [])
      .config(['$httpProvider', function($httpProvider) {
        $httpProvider.defaults.timeout = 5000;
    }]);

    Thanks for the post and update!!

    In researching this issue specifically for $resource, I thought I'd elaborate on what I've found:

    • This issue was logged in the tracker and in angular 1.1.5, there is support for passing the timeout property through to the $http request:

    https://github.com/angular/angular.js/issues/2190 http://code.angularjs.org/1.1.5/docs/api/ngResource.$resource

    • For those of us on earlier versions, specifically I am using angular 1.0.6, it is possible to edit the source file for angular-resource.js on line 396 you will find the call to $http where you can add the timeout property yourself for all resource requests.

    • Since it wasn't mentioned and I had to test Stewie's solution, when a timeout does occur, the way to tell between an error and an abort/timeout is checking the 'status' argument. It will return 0 for timeouts instead of say 404:

      $http.get("/home", { timeout: 100 })
      .error(function(data, status, headers, config){
              console.log(status)
          }
      
    • Since there are only a few cases where I need to use a timeout as opposed to setting it globally, I am wrapping the requests in a $timeout function, like so:

      //errorHandler gets called wether it's a timeout or resource call fails
      
      var t = $timeout(errorHandler, 5000);
      myResource.$get( successHandler, errorHandler )   
      function successHandler(data){
          $timeout.cancel(t);
          //do something with data...
      }
      
      function errorHandler(data){
          //custom error handle code
      }
