You define a resolver in Rust and Rapid will automatically generate a type schema that enables full-stack type-safety from frontend to backend:

use rapid_web::actix::HttpResponse;
use rapid_web::{rapid_web_codegen::rapid_handler, request::RapidPath};
use serde::{Deserialize, Serialize};

// The name/alias for your route (you will use this to call it from the client)
pub const ROUTE_KEY: &str = "getUser";

#[derive(Serialize, Deserialize)]
pub struct User {
    pub id: i32,
    pub name: String,
    pub age: u8,
}

pub type RapidOutput = User;

#[rapid_handler]
pub async fn query(user_id: RapidPath<i32>) -> HttpResponse {
    let user = User {
        id: user_id.into_inner(),
        name: "John".to_string(),
        age: 20,
    };
    HttpResponse::Ok()
    .content_type("text/html; charset=utf-8")
    .body(user)
}

You can then make fully type-safe HTTP requests to your rust backend with the rapid-react bolt client:

import { createBoltClient } from '@rapid-web/react';
import { routes, type Handlers } from './bindings.ts';

// Init your bolt client that you can use throughout your entire app for making requests
export const bolt = createBoltClient<Handlers, typeof routes>(routes, {
	transport: 'http://localhost:8080',
});

const userId = 1;

const req = await bolt('getUser').get(routes.getUser, userId);

The complete fullstack toolkit for building advanced, scaleable, and highly efficient software. Rapid is a toolkit that enables developers to create fullstack applications built on React and Rust. Rapid focuses on scalability and performance without sacrificing developer experience.

Developers have been building entire fullstack applications with ONE single language since the beginning of software and technology (C, C++, Java, Ruby, PHP, nodejs, etc). As time has progressed, programming languages have began to specialize and become more directed towards solving hyper specific problems. However, developers have still preferred the single language stack -- hence the popularity of things like NodeJS.

Developing applications with one language front-to-back means that engineers have the ability to share business logic across their entire development process, allowing them to iterate very quickly (additionally, things like hiring a development team are much easier and usually cheaper with a simpler tech stack). The downsides of this approach is that many languages (such as Javascript) were never meant to do absolutely everything -- this results in a situation where tools are used to solve problems they were never meant to solve.

Because of this, companies are often forced to move off of tooling as applications grow in scale. But what if we could use technologies at the beginning of the product development process that offers the great DX and simplicity of NodeJS without sacrificing scalability and performance?

Enter, Rapid -- a fullstack toolkit for building software applications with React and Rust!

Rapid is built to be very opinionated -- make less technical decisions, write more software, ship faster MVPs.

Rapid uses React and Rust as the foundation for its fullstack tooling. Do your heavy compute in Rust, render your user interface with React. Heavily integrated into Rapid is a feature rich CLI, allowing developers to create fullstack or backend applications with ease (rapid new --fullstack or rapid new --server).

Things like server-side rendering, hot-reload, Built-in UI components, authentication and much more come completely out-of-the-box with Rapid.

Rapid is built on multiple React and Rust libraries. View them below:

• Rapid-web
• Rapid-ssr (coming soon...)
• Rapid-cli
• Rapid-web-codegen

• @Rapid-web/react
• @Rapid-web/ui

• Rapid Web - A web server framework (rapid new --server)
• Rapid Ui -- a fully featured UI and CSS framework
• React frontend lib for data fetching, auth, etc
• Fullstack rapid apps with remix.run or nextjs (rapid new --remix or rapid new --nextjs)

• New mutation API for rapid-web
• Easy deployments with rapid deploy (GCP, Docker, Cloudflare, Netlify)
• rapid extract command for using rapid-web outside of a monorepo and maintaining full typesafety
• React-query and SWR integrations for rapid-web
• Icon library integrated into @Rapid/ui
• Wasm powered server functions?!
• Much more coming soon...

• A full featured react meta-framework built on Rapid (leveraging Rust and RSC)
• Rapid ORM (fully async ORM inspired by Prisma and built for Rust)

Refer to our getting started documents below:

• Rapid-UI
• Rapid-Web (Coming soon)
• Setting up a development environment
