Ryo js

Small js fullstack framework blazly fast Memo version

Installation

npm i ryo.js #or npm i ryo.js@github:marvelbark2/ryo-js

Features:

Routing based filesystem
Blazly fast (Try it by yourself)
Everything on src folder
Create apis, websockets, graphQL, Server-Sent-Events (SSE), preact components and serve static files.
SPA routing which makes the site so fast (Using Flamethrower)
Typescript (No types generated at least for now) supported without configuration needed (Example: https://github.com/marvelbark2/ryo-js-examples/blob/main/ryo-api/src/me.ts)

what you can do with Ryo js:

Routing system: Based on filesystem, you can build dynamic route, naming file with ":" prefix
Preact Components:
- Static Component (Sync data fetching): export data method returning a value
- Static Component (Async data fetching): export data object contains:
  - runner: Function async accepts stop method as argument (stop: called to stop caching) returns a value
  - invalidate(Optional): Field, duration per second to cache value, it's a global value.
  - shouldUpdate(Optional): Function accepts two values (Old, new) to re-render component on runtime when data changed after the cache invalidated
  - You can also use file as datasource by specifying the file path in data field also specify parsing way
- Server Component (TODO): export server method without returning anything
  - Here you can use async functional Component and use nodejs api and use JSX synthax but no client side will be run (Hooks, document ... will be ignored)
- Parent Component: For each component type described before, you can wrap them with a component independent state, you can either add entry.jsx as global wrapper or you can add it to the component itself by exporting the component naming it Parent (Check the ex Static async/fresh component down below). If both used, the parent component declared in the component itself will be used. (If you're using refreshed Static async/fresh component, you should provide the id passed as parent component props in jsx/html element that will be used to revalidate the component after data updated)
  - Each component could have a offline version but just export offline as component function that will be used when the client is offline
Api: export function with method name, like: export get() { return ... }
- JSON api: By returning js objects parsable values
- Streamable api: By returning object:
  - stream: Created stream, like readStream
  - length: Stream length (without reading it)
- You can build versionable apis where you can name file like service@1|2|...|n.(js|ts). Client-side, pass in http request header, a version as value for the key X-API-VERSION
- GraphQL endpoints (Still fixing subscriptions): You can build many graphql endpoint with separated schema by naming the route with this extension .gql.(ts | js)
Websockets: naming the file in src folder with ".ws.js" suffix:
- Return object match uWebSockets.js documentation
Server-Sent-Events: naming the file in src folder with ".ev.js" suffix:
- Export default: object with invalidate field (ms) and runner function (Async with params route if needed)
Subdomains: You can create subdomains by creating a folder with the _subdomains name in src folder and add index.js or index.ts file in it. (Example: _subdomains/api/index.ts) (You can use it to create a subdomain for your api) (You can also create dynamic subdomains by naming the folder with ":" prefix)
Errors pages: You can create error pages by creating a folder with the _errors name in src folder and code error with tsx or jsx extension. (Example: _errors/4XX.tsx) (You can handle all the error that error number starts with 4 like 404, 413 ...)

Security headers (2 complete): You can handle authentification and authorization by using ryo.config.js.

Example with jwt authentification and subdomain for blog project:

// file: ryo.config.js
/** @type {import('ryo.js').RyoConfig} */

const bcrypt = require("bcrypt");
const jsonwebtoken = require("jsonwebtoken");

const BASE_HOST = process.env.BASE_HOST || "localhost:3000";

const jwtAuthFilter = {
    doFilter(request, _response, setAuthContext, next) {
        const authHeader = request.getHeader("authorization");
        if (authHeader.length === 0 || !authHeader.startsWith("Bearer ")) {
            return next();
        }

        const jwt = authHeader.substring(7);
        const decoded = jsonwebtoken.verify(jwt, "secret");

        setAuthContext({
            id: decoded.username,
            roles: decoded.roles,
        })

        return next();
    }
}

module.exports = {
    subdomain: {
        baseHost: BASE_HOST,
    },
    security: {
        cors: false,
        csrf: true,
        authorizeHttpRequests: [
            {
                path: ["/", "/*.{js,css}", "/images/*", "/blog", "/_subdomain/test/**/*.{js,css}", "/_subdomain/**/test"],
                status: "allow",
            },
            {
                path: ["/blog/ff", "/_subdomain/test/page"],
                status: "auth",
            },
            {
                path: "/_subdomain/test/",
                roles: ["admin"],
            }

        ],
        authProvider: {
            async loadUserByUsername(username) {
                return {
                    username,
                    plainTextPassword: bcrypt.hashSync("123456", 10),
                    roles: [username],
                    onLoginSuccess: (res) => {
                        const jwt = jsonwebtoken.sign({
                            username,
                            roles: [username]
                        }, "secret");

                        console.log({
                            jwt, res
                        });
                        res.writeHeader("Authorization", `Bearer ${jwt}`);

                        res.end("Done")
                    }
                }
            },
            passwordEncoder: {
                encode: async (password) => bcrypt.hash(password, 10),
                matches: async (password, hash) => bcrypt.compare(password, hash),
            }
        },
        sessionManagement: {
            sessionCreationPolicy: "stateless",
        },
        filter: [
            jwtAuthFilter
        ]
    },
}

Progress Status:

Example:

websockets:

// Path: src/msg.ws.js
export default {
    open: (ws, req) => {
        console.log("NEW CLIENT on /msg");
    },

    message: (ws, message, isBinary) => { },

    close: (ws, code, message) => {

    }
}

API

JSON API:

// Path: src/api.js

export function get({ url }) {
    return {
        message: "Hello from " + url
    };
}

//body: object(json input) | Buffer(buffer array input) | undefined(none)
export function post({ body }) {
    // do something using body
    console.log({ body });
    return {
        message: "Hello from " + (typeof body)
    };
}

Streamable API:

// Path: src/file.js

import fs from 'fs';
import { join } from 'path';

export function get({ url }) {
    const path = join(process.cwd(), "./screen.mov");
    const stream = fs.createReadStream(path)
    stream.on("error", () => {
        //Handle error to avoid server crash
        console.log("error");
    })
    const length = fs.statSync(path).size;
    return {
        stream, length
    };
}

GraphQL endpoint:

// path: ttql.gql.ts
export default {
  schema: `
    type Query {
      hello: String
    }
    type Mutation {
      capitalize(message: String): String
    }
    `,
  resolvers: {
    hello: (_: unknown, ctx: { test: string }) => `${ctx.test}: hello world`,
    capitalize: ({ message }: { message: string }) => message.toUpperCase()
  },
  context: {
    test: "ME"
  }
}

use NODE_ENV=development to access graphql playground in GET request as example: /ttql.gql

    }
    type Subscription {
      todos: [Todo]!
    }
  `;

const resolvers = {

            text,
            done: false,
        };

        todos.push(newTodo);
        pubsub.publish(TODOS_CHANNEL, { todos });
        return newTodo;
    },
    setDone: (

        { pubsub }: { pubsub: PubSub }
    ) => {
        const todo = todos.find((todo) => todo.id === id);
        if (!todo) {
            throw new Error("Todo not found");
        }
        todo.done = done;
        pubsub.publish(TODOS_CHANNEL, { todos });
        return todo;
    },

    todos: (_: unknown, { pubsub }: { pubsub: PubSub }) => {

Offline component:

in the example suppose the display the default component if the user is online and the offline component if the user is offline (or if the server is down)

import { useEffect, useState } from "react";
import { test } from "@lib/db-exec";
import toast, { Toaster } from 'react-hot-toast';

function data() {
    test()
    //test()

        saveOnData(data: any) {
            console.log(data)
        }
    }
}

// Offline component
export function offline() {
    const [counter, setCounter] = useState(0);
    return (
        <div className="bg-gray-50">
            <Toaster
                position="top-right"
                toastOptions={{
                    duration: 10000,
                }}
            />

            <button className="px-4 py-2 bg-blue-900 text-white rounded-2xl" onClick={() => toast.success("Good")} >Toast</button>
            <button className="mx-3 px-4 py-2 text-blue-900 border-blue-900 border bg-white rounded-2xl"
                onClick={() => setCounter(c => c + 1)}
            >
                counting <b>{counter}</b>
            </button>

        </div>
    )
}


export default function index({ data }: { data: { counter: number, saveOnData: (data: any) => void } }) {
    const [count, setCount] = useState(data.counter);
    useEffect(() => {

                <p>You clicked <span className="font-bold text-lg text-gray-800">{count}</span> times</p>
                <button className="bg-blue-50 p-3 border-blue-700 text-blue-700 w-24 rounded-xl" onClick={() => setCount(count + 1)}>Click me</button>

                <span className="hover:cursor-pointer" onClick={() => toast.success('HOL')}>TOAST click</span>

                {/* SPA routing thanks to: Flamethrower */}
                <a href="/data">Data</a>
                <a href="/api">TEST</a>
                <button onClick={() => data.saveOnData({ a: "me" })}>API TEST</button>
            </div>
        </div>
    )
}

export {
    data
}

Middleware:

You can add middleware by adding a file in root of the project: middleware.(ts|js) You can also have catch errors by using last argument of the middleware function which could be null. You can also add structure to init stuff like database connection or other stuff. by exporting init function

Example:

//path: middleware.js

const getCookie = (req, name) => 
(req.cookies ??= req.getHeader('cookie')).match(getCookie[name] ??= new RegExp(`(^|;)\\s*${name}\\s*=\\s*([^;]+)`))?.[2]

export default function middleware(req, res, next, error) {
    const user = getCookie(req, "user")
    if (user) {
        return next();
    } else {
        res.writeHeader("Set-Cookie", "user=Guest")
        return res.writeStatus("401").end("You are not authorized")
    }
}

//Optional
export function init({ context }: { context: Map<string, any> }) {
    
    const db = ... // Inmemory database or other stuff
    context.set("articleDb", db); // The context, a global context, can be used in the data section or apis
}
