faster_react is a tiny Full-Stack React framework. He avoids Overengineering. This framework uses its own RSC engine, combining SSR and CSR, and automatically generates routes for React components. To utilize this, you must use the routes helper provided by the framework (React Router). The framework's configuration file is located at options.json.

Focus solely on development! This framework handles:

• 🛣️ Automatic route generation for React components.
• 🔄 Automatic inclusion of new React components when framework => "dev": true.
• 📦 Automatic frontend bundling when framework => "dev": true.
• ♻️ Automatic browser reload when framework => "dev": true.
• 🗜️ Automatic frontend minification when framework => "dev": false.
• 🚀 Automatic backend reload when changes are detected and framework => "dev": true.
• 🌐 Automatic detection of Deno Deploy environment. Test in other serverless environments by setting framework => "serverless": true.

Note: The project includes a simple application example demonstrating each functionality.

This framework uses a middleware library called Faster. Faster is an optimized middleware server with an incredibly small codebase (~300 lines), built on top of native HTTP APIs with no dependencies. It includes a collection of useful middlewares:

• 📄 Log file
• 🗂️ Serve static
• 🌐 CORS
• 🔐 Session
• ⏱️ Rate limit
• 🛡️ Token
• 📥 Body parsers
• 🔀 Redirect
• 🔌 Proxy
• 📤 Handle upload

Fully compatible with Deno Deploy and other enviroments. Examples of all resources are available in the README. Faster's ideology is simple: all you need is an optimized middleware manager; all other functionality is middleware.

This framework utilizes Headless Architecture [1] to build the application, combined with the Middleware Design Pattern [2] for defining API routes in the backend.

• Headless Architecture provides complete freedom to the developer, reducing the learning curve. Despite this freedom, there is an explicit separation between backend and frontend, which aids in development.
• The Middleware Design Pattern offers a practical and straightforward method for defining API routes.

All application folders are inside the app folder.

On the backend, if a Deno KV instance is available, access instances via Server.kv and Server.kvFs:

import { Server } from "faster";

See Deno KV settings in options.json.

• Deno KV File System (Server.kvFs): Compatible with Deno Deploy. Saves files in 64KB chunks. Organize files into directories, control the KB/s rate for saving and reading files, impose rate limits, set user space limits, and limit concurrent operations—useful for controlling uploads/downloads. Utilizes the Web Streams API.

Note: The project includes a simple application example demonstrating each functionality.

• Imports: Import your backend libraries here.
• Organization: Files can be organized into subdirectories.
• File Extension: Use .ts files.
• Structure: Flexible file and folder structure that doesn't influence anything.
• Routing: Define routes using any pattern you prefer.
• Exports: Must have a default export with a function (can be asynchronous).
• Function Input: Receives an instance of Server from faster.
• Usage: Perform backend manipulations here (e.g., fetching data from a database), including asynchronous calls.
• Routes: Define your custom API routes. For help, see: faster

• Optionality: A backend component is optional for a frontend component.

• Imports: Import your backend libraries here.

• Organization: Organize files into subdirectories.

• File Extension: Use .ts files.

• Correspondence: Each file should have the same folder structure and name as the corresponding frontend component but with a .ts extension.

  • Example:
    • Frontend: frontend/components/checkout/cart.tsx
    • Backend: backend/components/checkout/cart.ts

• Exports: Must have a default export with an object of type BackendComponent:

  import { type BackendComponent } from "@helpers/backend/types.ts";

• Usage: Intercept a frontend component request:

  • Before Processing (before?: RouteFn[]): List of middleware functions (see: faster). Use to check headers (ctx.req.headers) or search params (ctx.url.searchParams), like tokens, impose rate limits, etc.

    Note: To cancel page processing, do not call await next() at the end of a middleware function.

    Important: If you want the page to be processed, do not consume the body of ctx.req, or it will cause an error in the framework.

  • After Processing (after?: (props: JSONObject) => void | Promise<void>): Function receives the props that will be passed to the component. Add backend data to these props, such as data from a database. Can be asynchronous.

    Note: Only use props data in JSON-like representation, or hydration will fail.

• Imports: Import your backend libraries here.
• Organization: Organize files into subdirectories.
• File Extension: Use .ts files.
• Usage: Free to make exports or calls (including asynchronous).
• Purpose: Group common functions/objects for backend/api, backend/components, and other backend/files, such as user validations.

• Imports: Use only frontend libraries.
• Organization: Organize files into subdirectories.
• File Extension: Use .tsx files.
• Rendering: Rendered on the server and hydrated on the client.
• Routes Generated: Two routes per file (e.g., frontend/components/checkout/cart.tsx):
  • Page Route: For rendering as a page, e.g., /pages/checkout/cart.
  • Component Route: For rendering as a component, e.g., /components/checkout/cart.
• Initial Route (/): Points to frontend/components/index.tsx.
• Exports: Must have a default export with the React Function/Component.
• Props Passed to Component:
  • Form-submitted data (or JSON POST).
  • URL search parameters (e.g., /pages/myPage?a=1&b=2 results in {a:1, b:2}).
  • Manipulations from backend/components.

Application CSS style files.

• Multiple Files: Automatically compiled.
• Organization: Organize files into subdirectories.

• Imports: Use only frontend libraries.
• Organization: Organize files into subdirectories.
• File Extensions: Use .ts and .js files.
• Usage: Free to make exports or calls (including asynchronous).
• Difference from Components: Scripts are not automatically delivered to the client. They need to be imported by the frontend/components.
• Purpose: Group common functions/objects for React Functions/Components, like form field validations. Can have frontend/files common to other frontend/files.

Files served statically. Routes are generated based on the folder and file structure.

• Example: localhost:8080/static/favicon.ico matches static/favicon.ico.

Since the framework has its own routing system, a third-party routing library is unnecessary. Use the framework helper:

Note: Direct form submissions for page routes path also work.

import { getJSON, route } from "@helpers/frontend/route.ts";

interface Route {
  headers?: Record<string, string>; // When routing to a page, headers are encoded in the URL. Intercept them in ctx.url.searchParams in a backend/components file.
  content?:
    | Record<any, any>
    | (() => Record<any, any> | Promise<Record<any, any>>);
  path: string;
  startLoad?: () => void | Promise<void>;
  endLoad?: () => void | Promise<void>;
  onError?: (e: Error) => void | Promise<void>;
  disableSSR?: boolean; //For component routes. Disables SSR; defaults to false.
  elSelector?: string; // Required for component routes.
  method?: string; // Only for API routes. Optional; defaults to GET or POST.
}

Navigating to a Page with Search Params:

// URL search params passed as properties to the page. Props receive `{a:1}`
<button onClick={route({ path: "/pages/test?a=1" })}>
  Go to Test Page
</button>;

Passing Additional Parameters:

// Props receive `{a:1, example:"exampleStr"}`
<button
  onClick={route({
    path: "/pages/test?a=1",
    content: { example: "exampleStr" },
  })}
>
  Go to Test Page with Extra Data
</button>;

Using Asynchronous Content:

// Props receive `{a:1, ...JSONResponse}`
<button
  onClick={route({
    path: "/pages/test?a=1",
    content: async () => {
      return await getJSON({
        path: "/example/json",
        content: {
          test: "testData",
        },
      });
    },
  })}
>
  Go to Test Page with Async Data
</button>;

Programmatic Routing:

(async () => {
  if (user.loggedIn) {
    await route({
      path: "/pages/dash",
      content: { userId: user.id, token: token },
    })();
  } else {
    await route({ path: "/pages/users/login" })();
  }
})();

Loading a Component:

<button
  onClick={route({
    path: "/components/parts/counter",
    elSelector: "#counter",
  })}
>
  Load Counter Component
</button>;

Making an API Call:

<button
  onClick={async () => {
    const res = await getJSON({
      path: "/example/json",
      content: {
        test: "testData",
      },
    });
    console.log(res);
    alert(JSON.stringify(res));
  }}
>
  Fetch JSON Data
</button>;
