How to set a global http timeout in AngularJs

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 keep my code DRY.

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
  } 
  

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)

} ]);
