![]() Where sync-server is the path to your sync server file. sync-server -model=examples/tasks/internal/model/objectbox-model.json -unsecured-no-authentication, Then run the generator: go generate examples/tasks/internal/model/task.go to update the schema.ģ. For a more detailed description of what this can do, check out the Admin UI docs. This is most easily done by opening in any web browser. You can finally open the Admin UI to check if the task appears there. Let’s add a first task, called “task-cpp” (new task-cpp-1), to check if our C++ app syncs correctly. Here is the relevant Sync docs section on authentication options that explains how to use these.ĥ. We currently offer two authentication methods: shared secret and Google Sign-In. This is not what you would use in production. You can see how it was implemented in main.cpp.Īs this is just an example, we opted for no authentication to make things simple. ![]() Sync Client: launch, and the Sync Client will start automatically. You can find more information about the server in the Sync Server docs.Ĥ. Where sync-server is the path to your sync server executable. ![]() sync-server -model build/_deps/objectbox-src/examples/cpp-gen/objectbox-model.json -unsecured-no-authentication Start the ObjectBox Sync Server on Linux by running. Sync-enabled objects: note the first line in tasklist.fbs.ģ. Now configure and build the project via CMake: Configure (Clang), CMake: Build.Ģ. Target_link_libraries ( myapp objectbox - sync ) objectbox-default.json ) are the same everywhere. Important: When syncing between different apps, please make sure that the UIDs in the model JSON file (e.g. Start a Sync Client in the app - as one can see from the Sync Client docs, creating and starting a sync client is just a matter of a couple of lines of code.If you are using Docker, follow the steps outlined here. Note that this will only have to be started once and in this tutorial we’ll show you how to run the server on Linux. ObjectBox Sync Server - please apply for a free Sync Trial here to get your own copy of the Sync Server (available for Linux and Docker).Database objects enabled for sync - for this we need include the sync annotation in the ObjectBox schema file.The sync-enabled library - this is not the same as the general ObjectBox library and has to be downloaded separately.If you haven’t used the ObjectBox DB yet, please refer to the corresponding documentation: C/C++ Docs, Java/Kotlin/Dart Docs, Go Docs, Swift Docs.įor sync to work in any app, we generally only need four things: Note: The basic use of the database and its sync features is the same for all programming languages. If you want to see how each of these steps were incorporated into the example code, go to the next section. For a more detailed description, check out the Sync docs. In this section, we’ll quickly review how the the task-list example app uses ObjectBox Sync. Here are the repositories of each example app that we will be looking at today: ![]() This app is a standard cross platform ObjectBox example that is available for all language bindings. It acts as a filter for users to only see unfinished tasks. There is also a parameter to store the date when the task was completed. It stores tasks together with their creation dates. With the task-list app, users can create simple text-based tasks and mark them as done. In this tutorial, we are going to sync data across three instances of an example task-list app (written in C++, Go and Java). Syncing data across devices – a task-list app example Our powerful and intuitive APIs are a great match for multiplatform development environments. The ObjectBox database is quick to set up and free and easy to use. ObjectBox is a high-performance embedded database for Edge Computing with integrated Data Sync. The Database and Data Snyc works across platforms (iOS, Android, Linux, Rasbian, Windows, MacOS) and supports a variety of languages with easy native APIs ( Swift, Java, Kotlin, C / C++, Flutter / Dart, Golang).įor example, you can sync between an Industrial IoT sensor app in Go and a C++ monitoring application – and a mobile Android app written in Kotlin or Java – and of course an iOS app written in Swift – and… you get the drift □ Cross platform data sync can be simple: In this tutorial we will show you how you can easily sync data across devices.īuilt for fast and effortless data access on and across embedded devices from Mobile to IoT, ObjectBox keeps data in sync between devices for you.
