Suppose your app logs in a user. As a result, the app gets a user-token which uniquely identifies the user’s session with Backendless. If your app uses our SDK for Android, iOS, JS or .NET, the user-token value is managed directly by our libraries. Specifically, it is added to every API call to maintain the session…
Backendless Marketplace is a specialized store for backend functionality. Our vision for the marketplace is to make it a community-driven store for algorithms and API services. We also use the Marketplace for various Backendless”extenders” to help developers to increase the limits of the Backendless Cloud pricing plans. However, most importantly, the Marketplace can be used…
In this article, we will learn how to create QR codes with a custom Backendless API Service. For the sample code reviewed later in the article, we will use Java and the ZXing library (https://github.com/zxing). What is a QR code? A QR code is a computer-generated image with some information encoded in a graphical way….
In this article, we’ll talk about Backendless publish-subscribe messaging. One of the more common questions we receive is, “How can I get messages long after they are published?” The default mechanism in Backendless keeps messages in the published channel for a short period of time only (around a minute). This becomes a problem if a…
This post describes the process of developing an API Service in Backendless with JavaScript. You will learn: how configure your development environment include NPM dependencies run the service in the debug mode and test it using the Backendless console deploy the service to Backendless The service you will develop in this guide will provide APIs for…
With the introduction of Deployment Models for business logic (Cloud Code), we also added support for “invocation chains”. This is an ability to chain together multiple server-side event handlers registered to process the same event. Previously, you could inject cloud code into the API invocation flow as shown in the image below: For any API…
We are preparing one of the final Beta builds for Backendless 4. The build should be released early in the week of June 19th. We plan to release the service out of beta shortly after that. One of the important changes in the upcoming service update will be the introduction of deployment models. When the…
One of the new features we will be releasing in the final update of Backendless 4 beta is support for “business logic (Cloud Code) deployment models”. This is a new concept introduced in Backendless 4. A “deployment model” combines individual API event handlers, timers and API services into a single group. The purpose of that…
For anyone developing business logic (Cloud Code) in JavaScript, we have put together some suggestions for troubleshooting your deployment. The page is added to the product documentation. One of the new features described in the doc is the ability to redirect console.log messages to Backendless logging. Once your JS code is deployed to production, messages…
