Ember-cli-ajax-logger !Travis CI Build Status

This simple ember-cli addon add ability to log ajax requests inside application.

##Motivation
Add access to requests/responses logs while intergration testing with Selenium.

#Configuration

Default configuration is
``javascript
{
disabled: false,
globalName: 'emberCliAjaxLogger',
getItemForSerializer: (event, jqXHR, ajaxOptions)=> {
const { type, data, url } = ajaxOptions;
return JSON.stringify({
url,
type,
data,
responseText: jqXHR.responseText
});
}
}
`

It's a part of env-config (section 'ember-cli-ajax-logger' in config/environment.js )

`javascript
module.exports = function(environment) {
var ENV = {
modulePrefix: 'dummy',
environment: environment,
baseURL: '/',
locationType: 'auto',
EmberENV: {
},

APP: {

},

'ember-cli-ajax-logger': {
globalName: 'emberCliAjaxLogger'
}
};


return ENV;
};
`

Option globalName set the window property which contains logger object.

#API

To use logger instance you should use window[globalName] by default it's window.emberCliAjaxLogger.

Logger instance has next interface ( most of functions return logger instance thus you can use chain constructions )

- clear - clear log. Return logger instance
- getSerialized - return string which is serialized array build by item process function
- setFilterFunction - set filter function which allow control list of items in getSerializedresult. Takes callback as param. Callbak receive log items, index and log list ( tipical for [].filter in js ). Return logger instance
- setGetItemForSerializer - set process function which use to build output for getSerialized method. Takes callback as param. Callbak receive log items, index and log list ( tipical for [].map in js ). Return logger instance
- register - add link into global namespace ( window ). Takes string with name to register as param. Return logger instance
- subscribe - enable subscription via $.ajaxComplete to add handler from logger instance. Return logger instance
- enableLogging - enable logging ( by default subscribe enable handler, but not add item into log. Return logger instance
- disableLogging - disable logging. Return logger instance

Example

`javascript
LoggerObject
.setGetItemForSerializer(({ _event, xhr, settings })=> {
const { type, data, url } = settings;
return JSON.stringify({
url,
type,
data,
responseText: xhr.responseText
});
})
.setFilterFunction((_item)=> true) // no filtering
.register('emberCliAjaxLogger')
.subscribe()
.enableLogging();
