StrongLoop Upgrades LoopBack API Framework With Replication and Offline Synchronization Support

LoopBack Greatly Simplifies Data Synch and Replication for Mobile Apps Requiring APIs and Connectivity to Enterprise Data Sources

SAN MATEO, CA -- (Marketwired) -- 05/22/14 -- StrongLoop, the leading provider of solutions for Node.js, today announced support for replication and offline synchronization in its LoopBack API framework. Loopback is an open source API framework written in Node.js used to connect devices to enterprise datasources. This new functionality is available for Oracle, SQL Server, MongoDB, PostgreSQL, MySQL and any LoopBack connector which supports create, read, update, delete (CRUD) operations.

Enterprise mobile apps require offline sync capabilities

The ability to work offline has emerged as a requirement for almost all enterprise mobile applications that are data-driven. Up until now, developers first had to figure out how to locally store a subset of the application's data. Second, they had to implement a mechanism that could keep the data synchronized on both the client and server. The previous generation of synchronization and replication technologies that tried to address these challenges were low level and inflexible, with little variety of data sources they supported. Fine grained controls on the behavior for common use cases like change detection and conflict resolution were also lacking.

Replication and offline support in the Loopback API framework

Today, StrongLoop is happy to announce that it has developed data synchronization and replication capabilities within the LoopBack API framework that are isomorphic in design. This means that for the first time developers can easily synchronize to and from various databases without requiring constant network connectivity. LoopBack's replication also handles the complexity of moving data between devices, device to server and server to server. This means developers can focus on the front end versus the mechanics of how to replicate data between disparate databases, like Oracle, SQL Server, MongoDB and MySQL, whether they be in cloud or in the datacenter.

"Our customers have been telling us that one of the biggest technical challenges they face is exposing APIs to connect to legacy datasources and giving developers an easy way to deliver offline sync in their apps," said Issac Roth, StrongLoop CEO. "With replication and offline sync now baked into the LoopBack API framework, developers get both both benefits from the same toolset."

Additional use cases for LoopBack's replication capabilities

  • In the browser, developers can attach to a local storage database and then synchronize it with the server when it regains connectivity.
  • In a "turn" based multiplayer game, the synchronization of game objects can be performed with an in-memory database on the server and client.
  • In an enterprise application, you can synchronize an Oracle and MongoDB database, allowing you to leverage the performance characteristics of MongoDB, while defaulting to Oracle for persistence.
  • Data can be replicated from a less performant database into a datastore with better read performance, such as Redis.

Pricing and availability

The offline sync capabilities of the LoopBack API framework are generally available. To learn more, visit the Loopback product page or download the framework from npm. Visit the subscriptions page for information about pricing and support for LoopBack.

As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Bradley Holt, Developer Advocate at IBM Cloud Data Services, will demonstrate techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk will be on IBM Cloudant, Apa...
As more and more data is generated from a variety of connected devices, the need to get insights from this data and predict future behavior and trends is increasingly essential for businesses. Real-time stream processing is needed in a variety of different industries such as Manufacturing, Oil and Gas, Automobile, Finance, Online Retail, Smart Grids, and Healthcare. Azure Stream Analytics is a fully managed distributed stream computation service that provides low latency, scalable processing of streaming data in the cloud with an enterprise grade SLA. It features built-in integration with Azur...
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
“The Internet of Things transforms the way organizations leverage machine data and gain insights from it,” noted Splunk’s CTO Snehal Antani, as Splunk announced accelerated momentum in Industrial Data and the IoT. The trend is driven by Splunk’s continued investment in its products and partner ecosystem as well as the creativity of customers and the flexibility to deploy Splunk IoT solutions as software, cloud services or in a hybrid environment. Customers are using Splunk® solutions to collect and correlate data from control systems, sensors, mobile devices and IT systems for a variety of Ind...
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it.
