3x Faster: Jai Server handles an impressive ~40,304 req/sec compared to Express.js's ~13,221 req/sec

67% Lower Latency: 24.32ms average for Jai Server vs 74.66ms for Express.js

2.6x Higher Throughput: 8.5 MB/sec for Jai Server vs 3.25 MB/sec for Express.js

Consistent Performance: Jai Server shows remarkably low standard deviation in requests per second, indicating stable and reliable performance under high load

Efficient Resource Utilization: Jai Server processes 3 times more requests while maintaining lower and more consistent latency

Jai Server delivers exceptional, consistent, and scalable performance, making it the ideal choice for high-load applications, microservices, real-time systems, and performance-critical projects. #performance-comparison #high-throughput #low-latency

Get started with Jai Server in your project:

Sends a response in HTML, text, or any other format. Automatically sets the appropriate Content-Type header.

Sends a JSON response with Content-Type: application/json.

Redirects the client to the given URL. The default status code is 302.

Sets the HTTP status code for the response. Chainable with other response methods.

Sets custom headers for the response.

Serves a file to the client. Options can include root directory, cache settings, etc.

Jai Server supports middleware and routers for more complex applications:

Creates a new Jai Server instance.

Option Type Description Default host string Host name 'localhost' port number Port number 3000 static object Static file serving options (jai-static) null https object HTTPS options null http2 boolean Enable HTTP/2 false allowHTTP1 boolean Allow HTTP/1 on HTTP/2 server true allowHTTP1 boolean Allow HTTP/1 on HTTP/2 server true timeout number Timeout req after ms, default 60000(1min) 60000

Routes an HTTP request, where METHOD is the HTTP method in lowercase.

Mounts middleware function(s) at the specified path.

Starts the server.

Middleware Chaining: Create complex request processing pipelines

Custom Error Handling: Implement application-specific error management

Request Body Parsing: Built-in support for JSON and URL-encoded bodies

Modular Routing: Organize routes using the Router class

WebSocket Support: Real-time, bidirectional communication

Database Integration: Easy connection with popular databases

Authentication Middleware: Secure your routes and APIs

Rate Limiting: Protect your server from abuse

CORS Support: Configure Cross-Origin Resource Sharing

Compression: Optimize response size for faster transmission
