+# fh-sync
 
-Node.js and express.js based mobile app data synchronization library. 
+Node.js implementation of the FeedHenry Data Syncronisation Server.
+To be used in conjunction with the FeedHenry Data Syncronisation Client.
 
-*Note* WIP. This repo targets to decouple fh-sync from other API's in fh-mbaas-api package.
-For official and supported version of fh-sync please refer to fh-mbaas-api npm package.
+*Note* WIP. The goal of this repo is to decouple fh-sync from other API's in fh-mbaas-api package.
+For the currently maintained fh-sync implementation, please refer to https://github.com/feedhenry/fh-mbaas-api.
 
 ## Usage
- fh-sync  is included as standard with your cloud app code.
 
 ```
-npm install --save fh-sync-cloud
+npm install --save fh-sync
 ```
 
-This will install the latest version of fh-sync-cloud and save the installed version in your package.json
+This will install the latest version of fh-sync and save the installed version in your package.json
 
-## Documentation
-Documentation for the fh-sync-cloud API is maintained at the [FeedHenry API Docs.](http://docs.feedhenry.com/v3/api/cloud_api.html)
+To use sync in your application, require it and call `connect`.
 
+```js
+var sync = require('fh-sync');
 
-## Tests
-In order to run the tests, please make sure you have [Docker](https://www.docker.com/) installed.
-
-Before running tests do:
+var mongodbConnectionString = 'mongodb://127.0.0.1:27017/sync';
+var redisUrl = 'redis://127.0.0.1:6379';
 
-```
-npm install
-npm install -g grunt-cli
+sync.api.connect(mongodbConnectionString, {}, redisUrl, function(){});
 ```
 
-Then to run the tests use ```npm test```
+To configure a dataset for syncing, wait for the `sync:ready` event, then `init` the dataset.
 
-## Caveats
+```js
+sync.api.getEventEmitter().on('sync:ready', function() {
+  console.log('sync ready');
 
-### Two sync loops per sync frequency
-Two sync loops may be invoked per sync frequency if the server-side sync frequency
-differs from the client-side frequency.
+  sync.api.init('myDataset', {
+    syncFrequency: 10 // seconds
+  }, function() {});
+});
+```
 
-This is because the client and server sync frequencies are set independently.
-Setting a long frequency on a client does not change the sync frequency on the
-server.
+*TODO*
 
-The `syncFrequency` value of the dataset on the server should be set to the
-`sync_frequency` value of the corresponding dataset on the client to avoid this.
+* mounting routes in an express application that `invoke` sync on demand
+* hooking up a FeedHenry Data Syncronisation Client to the server
 
-For example:
-  * `sync_frequency` on the client-side dataset is also set to 120 seconds.
-  * `syncFrequency` on the server-side dataset is set to 120 seconds.
+## Tests
+In order to run the tests, please make sure you have [Docker](https://www.docker.com/) installed.
 
-## API logging
+Before running tests do:
 
-Users of the fh-mbaas-api can then enable logging if they would like to see more output. This is useful for debugging purposes.
-It's possible to pass environment variables to enable the logging according the rules specified for [debug](https://www.npmjs.com/package/debug) module:
-
 ```
-DEBUG="fh-mbaas-api:*" ./yourscript 
+npm install
+npm install -g grunt-cli
 ```
-If `DEBUG_COLORS=0` is passed also it will print log messages with proper timestamps. This is automatically enabled outside properly supported terminal.
+
+Then to run the tests use ```npm test```
+
