Sync

This family of device APIs provided by dronahq.js allows a micro-app an easy way to submit data in background via http requests.

It has the following method(s) -

It also provide the following event(s) -

upload()

This method uploads JSON data to a remote URL. Optionally you can also upload an image file using this request. The JSON data is sent in the request body. By invoking this method, the micro-app will keep trying the data upload until the server returns an http 2XX response. For failed requests, the app will keep trying to upload the data in every 1 hour.

Please note that calling this method only submits the request to the Container App. Actual upload happens when the sync service is triggered the next time. You can call the refresh method to trigger the sync service.

REQUEST PARAMETERS

Parameter Type Description
remoteurl string Required. http(s) URL of your API where the data should be submitted
requestmethod string Required. HTTP method type for the request. Supported values are ‘POST’ & ‘PUT’
requestdata object Required A valid JSON object which will be sent in the request body.
imagefilepath string Optional File Path URI for the image which should also get uploaded along with the request.
options object Optional A object with more request parameters like header & timeout.
fnsuccess function Optional Callback function which will be called after request has been added to the queue.
fnerror function Optional Callback function which will be called when request could not be added to the queue. 
var remUrl = 'https://yourserver.com/api/users/134/action/updatedesignation';
var dronaHQReqMethod = 'POST';
var dronaHQReqData = {designation_code : 'X601'};
var reqImgURI = '';
var headers = [{ Authorization: 'Auth a2FuY2hhbkBkcm9uYW1vYmlsZS5jb206bWFpbEAxMjM0' }];

var options = {};
options.header = headers;

DronaHQ.sync.upload(remURL, dronaHQReqMethod, dronaHQReqData, reqImgURI, options);

refresh()

Calling this method will wake up the sync service and triggers any pending upload.

//refreshType = 'upload' for submitting any pending uploads

DronaHQ.sync.refresh(refreshType);

getpendinguploadcount()

This method gives a count of all the pending upload requests.

DronaHQ.sync.getPendingUploadCount(function(count){}, function(e){});

uploadcomplete

DronaHQ.sync.uploadcomplete

This event is triggered whenever the sync service has finished processing all pending requests, even if a few requests have failed to complete successfully. The failed requests are retried next time the service runs.

document.addEventListener('dronahq.sync.uploadcomplete', function(){
        //Refresh task is complete.
});

removeRequest()

This method allows users to remove offline request, User must provide list of offline request ID in array format.(received while creating new offline sync request)

DronaHQ.sync.removeRequest([id1,id2]);

Response for the request is

getPurgeData()

This method will return details of all the deleted or failed requests.

DronaHQ.sync.getPurgeData();

Response will be an array of JSON Objects. Each Object contains keys as follows:

Parameter Type Description
data JSONObject JSONobject which was sent in the request body
remote_url string URL of the API
request_method string HTTP method type of the request (POST/PUT/GET)

is_completed boolean Is request saved in server or pending
is_delete boolean Has request id been auto deleted
is_corrupted boolean Does file exist or auto purged or file is renamed or moved to some other location, Default is False
response string Api response from the server

triggerSync()

This method will wake up the sync service and trigger any pending upload or download requests.

DronaHQ.sync.triggerSync();

removeRequest()

This method allows users to remove already added requests, User must provide list of offline request IDs (which were received while creating offline sync requests) in jsonarray format

DronaHQ.sync.removeRequest([id1,id2]);

getChannelDB()

DEPRECATED

Please refer getDocument() as a alternative of this method. This method is related to CouchDB. In order to get all channel specific document i.e pluginid ‘0’ call this method.

DronaHQ.sync.getChannelDB();

getAppDB()

DEPRECATED

Please refer getDocument() as a alternative of this method. This method is related to CouchDB. In order to get all microapp specific document i.e pluginid call this method.

DronaHQ.sync.getAppDB();

getDBDetails()

Returns CouchDB(Server details) and environment(Dev, Beta, Prod) of the micro app.

DronaHQ.sync.getDBDetails();

getDocument()

GetDocument method can be used to for getChannelDB(), getAppDB(). Retrieve data based on the query(Mango Query) passed by the user. documentName, query, apikey,type, filterMode, isChannelDoc, skip, limit)

Following are the arguments required to call the method

Parameter Type Options DefaultValue Description
documentName String
“” In couch document ‘table_name’ key is the document name.
query String
“” Pass mango query as input. Query should be without ‘selector’ keyword.
apikey String
“” Not yet implemented
documentType String record record_schema internal internal_schema “record” Documents of CouchDB are categorized in four types depending on the type of data document contains. ‘record’ doc type contains user data. ‘record_schema’ doc type contains schema of document “record”. ‘internal’ doc type contains data of internal structures of couchDb. ‘internal_schema’ doc type contains schema of document “internal”.
filterMode String 0, 1, 2, 3 “3” The request will be processed based on the filterMode. 0 - Local Mode In local mode query will be processed locally i.e on the data which is available in mobile storage. 1 - API Mode In API Mode the request will be forwarded to server. 2 - First Local Mode then API Mode First query will be processed locally if data is not found then request will be forwarded to server. 3 - First API Mode then Local Mode First query will be forwarded to server if data is not found and if device is offline then query will be processed locally.
isChannelDoc Boolean true/false false To get channel documents i.e pluginid ‘0’ set this flag as ‘true’ else it will return documents of currently open microapp.
skip Integer 0 or value > 0 0 To skip specific number of documents while processing the query.
limit Integer 0 or value > 0 5 To return only specific number of documents in callback response

NOTE: The callback response data will be associated with key ‘schema’ if documentType parameter is record_schema or internal_schema. It will be associated with key ‘data’ if documentType parameter is record or internal. Else string response will be provided.

DronaHQ.sync.getDocument(documentName, query, apikey, documentType,
                                                 filterMode, isChannelDoc, skip, limit);

Sample:
Without Query:
        DronaHQ.sync.getDocument("","","","","0",true,0,25);

With Query:
        var mangoQuery = {channel_id: 108,"created_by":"[email protected]"}
        DronaHQ.sync.getDocument("",JSON.stringify(mangoQuery),"","","0",true,0,25);
