RainViewer SDKs & Libraries: Official & Community Tools (2026)

SDKs overview

RainViewer offers a suite of SDKs and libraries designed to simplify the integration of its weather radar and forecast data into various applications. These tools abstract direct HTTP requests to the RainViewer API methods, providing language-specific objects and functions for data retrieval and display. The primary focus of these SDKs is to enable developers to access real-time radar images, historical data, and forecast information without needing to manage raw API calls or image tile processing.

The SDKs generally cover functionalities such as:

• Radar Image Retrieval: Fetching the latest radar images or specific historical frames.
• Tile Handling: Managing geographic tile coordinates for map overlays.
• Data Parsing: Converting API responses into structured data objects.
• Map Integration: Providing utilities for displaying radar data on popular mapping platforms.

These libraries aim to reduce development time and effort by offering pre-built components and examples, allowing developers to focus on application-specific logic rather than the intricacies of weather data acquisition. The availability of multiple language implementations supports development across diverse technology stacks, from web applications using JavaScript to mobile applications built with Swift or Kotlin.

Official SDKs by language

RainViewer provides official SDKs and code examples across several programming languages to facilitate integration with its weather radar API. These SDKs are maintained to ensure compatibility with the latest API versions and features, offering structured approaches to accessing radar data, historical imagery, and forecast information. The table below outlines the primary official offerings and their typical installation methods.

For detailed usage instructions and examples for each language, refer to the RainViewer API documentation.

Installation

Installation methods for RainViewer SDKs vary by programming language and ecosystem. The following provides general guidance for common languages. Always consult the specific SDK's documentation for the most current and precise installation instructions.

JavaScript (Node.js/Browser)

For JavaScript projects, the RainViewer SDK is typically installed via npm or yarn:

npm install @rainviewer/sdk
# or
yarn add @rainviewer/sdk

This package can be used in both Node.js environments and client-side web applications, often bundled with tools like Webpack or Rollup.

PHP

PHP libraries for RainViewer are usually managed with Composer:

composer require rainviewer/api-client

After installation, Composer's autoloader can be included in your project to use the SDK classes.

Python

Python SDKs are distributed via pip, the Python package installer:

pip install rainviewer-api

Once installed, you can import the module and begin using its functions.

Ruby

Ruby gems are installed using the gem command:

gem install rainviewer-api-client

Require the gem in your Ruby script to access the client.

Go

Go packages are typically fetched using go get:

go get github.com/rainviewer/go-sdk

Then, import the package in your Go source files. For more on Go module management, see the Go Modules documentation.

Swift (iOS/macOS)

For Apple platforms, dependencies are often managed with CocoaPods or Swift Package Manager (SPM).

CocoaPods:

Add to your Podfile:

platform :ios, '12.0'
use_frameworks!

target 'YourApp' do
  pod 'RainViewerSDK'
end

Then run pod install.

Swift Package Manager:

In Xcode, go to File > Add Packages and enter the repository URL (e.g., https://github.com/rainviewer/ios-sdk.git).

Kotlin (Android)

For Android development, the SDK is typically added as a Gradle dependency in your app's build.gradle file:

dependencies {
    implementation 'com.rainviewer:android-sdk:VERSION_HERE'
}

Replace VERSION_HERE with the latest available version from the RainViewer documentation.

Java

Java projects can include the SDK via Maven or Gradle. For Maven, add this to your pom.xml:

<dependency>
    <groupId>com.rainviewer</groupId>
    <artifactId>java-sdk</artifactId>
    <version>X.Y.Z</version>
</dependency>

For Gradle, add to your build.gradle:

dependencies {
    implementation 'com.rainviewer:java-sdk:X.Y.Z'
}

Replace X.Y.Z with the appropriate version number.

C# (.NET)

For .NET applications, the SDK is available as a NuGet package:

Install-Package RainViewer.ApiClient

This can be run from the Package Manager Console in Visual Studio or via the .NET CLI.

Quickstart example

This quickstart example demonstrates how to retrieve and display the latest weather radar data using the RainViewer JavaScript SDK. This example fetches radar tiles and overlays them onto a map, illustrating a common use case for the API.

JavaScript Example (Web Browser)

This example uses a common mapping library (e.g., Leaflet.js) to display RainViewer radar data. You would need to include Leaflet.js and its CSS in your HTML as well.

                console.error('Error fetching radar data:', error);
            }
        }

        addRadarLayer();

        // Optional: Update radar every 5 minutes
        setInterval(addRadarLayer, 5 * 60 * 1000); 
    </script>

This code snippet initializes a Leaflet map and then fetches the most recent radar frame from RainViewer using its SDK. It constructs a tile URL and adds it as an overlay to the map. Users will need an API key for production use, although many SDK functions operate without one for public data access. For more detailed JavaScript SDK usage, including historical data playback and customization, refer to the RainViewer JavaScript SDK documentation.

Community libraries

While RainViewer provides robust official SDKs for major programming languages, the developer community also contributes various libraries and wrappers. These community-driven projects can offer alternative approaches, integrations with specific frameworks, or support for niche use cases not directly covered by official releases.

Examples of potential community contributions might include:

• Framework-specific integrations: Libraries tailored for frameworks like React, Angular, Vue.js, or specific backend frameworks that simplify state management or component-based data display.
• Specialized mapping integrations: Wrappers for less common mapping libraries beyond Leaflet or OpenLayers, such as Mapbox GL JS or Google Maps Platform with custom rendering techniques. The Google Maps JavaScript API provides a flexible platform for custom overlays.
• Utility tools: Small utilities for data processing, caching, or performance optimizations specific to certain application types.
• Unsupported languages: SDKs or client libraries for languages not officially supported by RainViewer, built by developers who need to integrate the API into their preferred environments.

When considering community libraries, it is important to assess their maintenance status, documentation quality, and compatibility with the latest RainViewer API specifications. Community libraries may not always keep pace with API changes as quickly as official SDKs. Developers are encouraged to check platforms like GitHub, NPM, PyPI, or RubyGems for community contributions by searching for 'RainViewer' and filtering by language or framework.

Developers contributing to or using community libraries should always prioritize security and performance. Validation of data and API key management practices in third-party libraries is crucial, especially in production environments to avoid vulnerabilities or unexpected rate limit issues with the RainViewer API.
