runtime

Detects the current JavaScript runtime environment. This function helps determine whether the SDK is running in a browser, Node.js, or Deno environment, enabling conditional logic and environment-specific optimizations.

Parameters

None

Returns

A string literal indicating the detected runtime environment:

• "browser" - Running in a web browser environment
• "nodejs" - Running in Node.js environment
• "deno" - Running in Deno environment

Examples

Basic Usage

const env = Deno.api.functions.runtime();
console.log(`Running in ${env} environment`);

switch (env) {
    case 'browser':
        console.log('Browser environment detected');
        break;
    case 'nodejs':
        console.log('Node.js environment detected');
        break;
    case 'deno':
        console.log('Deno environment detected');
        break;
}
