Installation

You can install ExpressDirectoryRouter using npm, yarn, or pnpm for example:

npm install @kyri123/express-directory-router

yarn add @kyri123/express-directory-router

pnpm add @kyri123/express-directory-router

Usage

To use ExpressDirectoryRouter, simply require it and use it as middleware in your Express application:

Javascript

const express = require('express');
const { installAppExpress } = require('express-directory-router');

const app = express();

// install routings with default settings
installAppExpress(app).then(() => {
	app.listen(3000, () => {
		console.log('Server is running on http://localhost:3000');
	});
});

Typescript

import express from 'express';
import { installAppExpress } from 'express-directory-router';

const app = express();

// install routings with default settings
installAppExpress(app).then(() => {
	app.listen(3000, () => {
		console.log('Server is running on http://localhost:3000');
	});
});

Middleware

Middleware can be used in the following formats the name of the file must ne middleware.(js|ts) Following named exports are supported:

• GET
• POST
• PUT
• DELETE
• PATCH
• GLOBAL -> GLOBAL is a special middleware that is executed for all routes and methods (also in subdirectories)
• WILDCARD -> WILDCARD is a special middleware that is executed for all routes and methods (BUT NOT in subdirectories)
• HEAD
• OPTIONS
• ALL
• TRACE

import { type MiddleWareInit } from '@kyri123/express-directory-router';

export const GET: MiddleWareInit = async (payload) => {
	return [
		(req, res, next) => {
			return next();
		}
	];
};

export const GLOBAL: MiddleWareInit = async (payload) => {
	return [
		(req, res, next) => {
			return next();
		}
	];
};

Directory-Routes

Route the directory structure is as follows:

Directory	Description	Directory	Express Route
XYZ	name of the Route for exmaple	xyz/123	/xyz/123
[paramname]	will used for params	xyz/[paramname]	/xyz/:paramname
[paramname...]	will used for params and route all subdirectorys here	xyz/[paramname...]	/xyz/:paramname*
(xyz)	will ignored for routing so used for organisation	xyz/(group)/123	/xyz/123
[...]	Will route all subdirectory here	xyz/[...]	/xyz/*
XYZ	name of the Route for exmaple	xyz/123	/xyz/123

Route-Functions

Routes can be used in the following formats the name of the file must ne ('get'|'post'|'put'|'delete'|'all'|'head'|'connect'|'options'|'trace').(js|ts): named exports:

• middleware -> (optional) - Middleware for the route (see Middleware)
• default -> (required) - The route handler must be a RoutingFunction

```ts
import { ResponseStatus, jsend, type MiddleWareInit, type RoutingFunction } from '@kyri123/express-directory-router';

export const middleware: MiddleWareInit = async (payload) => {
	return [
		(req, res, next) => {
			return next();
		}
	];
};

const handler: RoutingFunction = async ({ response, request, next, payload }) => {
	response.status(200).json(
		jsend(ResponseStatus.Success, {
			data: { message: 'Hello World' }
		})
	);
};

export default handler;
