SQLite REPLACE is *not* UPSERT. If a conflict occurs, it first deletes the existing row, then inserts a new row. This means that AUTOINCREMENT primary keys change. This will break foreign keys to that value, which we use. Instead we must try an UPDATE, and fall back to an INSERT if the UPDATE changes zero rows.
Mapbox GL Native
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox GL Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.
The Mapbox GL ecosystem
This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a GLFW-based demo application for Ubuntu Linux and OS X. The SDKs target the usual languages on their respective platforms:
| SDK | Languages | Build status |
|---|---|---|
| Mapbox GL Native | C++14 |   |
| Mapbox Android SDK | Java |  |
| Mapbox iOS SDK | Objective-C or Swift |  |
| Mapbox OS X SDK | Objective-C or Swift |  |
| node-mapbox-gl-native | Node.js | |
Additional Mapbox GL Native–based libraries are developed outside of this repository:
- React Native Mapbox GL for React Native applications on iOS and Android
- QMapboxGL for Qt-based applications
- Telerik’s Mapbox plugin for Apache Cordova Hybrid applications
- Telerik’s Mapbox plugin for NativeScript Hybrid applications
- Xamarin's Mapbox component for Xamarin Hybrid applications
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
