ng-http-estimate

Automatic $http request time estimates

Demo, basic example, custom estimator, reporting accuracy, low-level

npm|bower install ng-http-estimate

Include 'dist/ng-http-estimate.js' script in your page and add dependency on 'http-estimate'

angular.module('app', ['http-estimate']);

Place the loading element into the body, you can also style it

<body>
    <http-estimate></http-estimate>
    ...
</body>

The element will appear automatically on HTML requests and will show estimated remaining time (if previously computed) or "loading ..." message. Optionally, include 'dist/ng-http-estimate.css' file to get the default centered style.

Features

  • Measurements are saved in the local storage.
  • The $http requests are automatically intercepted. If you want to disable intercept and control the start / stop events, use config provider
.config(function (httpEstimateProvider) {
  httpEstimateProvider.set({
    interceptHttp: false
  });
})
  • You can pass your own estimator function via config provider. The function can use built-in estimator and should return the wait time in milliseconds. For example:
.config(function (httpEstimateProvider) {
  httpEstimateProvider.set({
    estimator: function (cacheEstimator, url) {
      console.log('need to estimate how long get request to', url, 'would take');
      var estimate = cacheEstimator(url);
      console.log('built-in cache estimator says', estimate);
      console.log('will trust it');
      return estimate;
    }
  });
})
  • You can pass 'accuracy' function via config provider to receive result after a request completes. Useful to collect analytics how accurate the measurements were
.config(function (httpEstimateProvider) {
  httpEstimateProvider.set({
    estimator: function (cacheEstimator, url) {
      ...
    },
    accuracy: function (url, estimate, took) {
      console.log('estimated request to', url, 'to take', estimate, 'took', took, 'ms');
    }
  });
})
  • Low level interface. You can inject 'httpEstimateLowLevel' into your application and call the low-level methods start(name) and stop(name). Great for custom duration estimation with http intercepts disabled.
.controller('demoController', function ($scope, httpEstimateLowLevel) {
  $scope.startLoad = function startLoad() {
    httpEstimateLowLevel.start('/foo/bar');
  };
  $scope.stopLoad = function stopLoad() {
    httpEstimateLowLevel.stop('/foo/bar');
  };
});
  • Verbose console log output for debugging.
.config(function (httpEstimateProvider) {
  httpEstimateProvider.set({
    verbose: true
  });
})
