RouteX

NPM version NPM downloads

NOTE: This package is similar to @tralse/routex. Progress from @tralse/routex will be continued to @tralsejr/routex.

RouteX is a lightweight package designed to simplify the management and loading of routes in an Express.js application based on configuration files. It automates the process of routing setup, allowing developers to define routes in configuration files and seamlessly integrate them into your Express.js projects.

RouteX Function

The RouteX function in RouteX facilitates automatic loading of routes into an Express.js application based on a configuration file. It recursively scans the specified directory for route files and dynamically mounts them in the Express app, with endpoints corresponding to the file structure.

Installation

Install RouteX via npm:

npm install @tralsejr/routex

Usage

const express = require("express");
const { RouteX } = require("@tralsejr/routex");

const app = express();

(async () => {
  // Load routes using RouteX
  await RouteX(app);

  // Start server
  const PORT = process.env.PORT || 3000;
  app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
  });
})();

Configuration

To configure Routex, you need to import defineConfig. Then place one of the following configuration files in your project's root directory:

  • routex.config.js - For CommonJS projects.
  • routex.config.cjs - For CommonJS projects also.
  • routex.config.mjs - For ESM projects.

Example:

//routex.config.js

const { defineConfig } = require("@tralsejr/routex");

module.exports = defineConfig({
  routesPath: "./src/routes",
});

/routes/users/index.mjs:

import { Router } from "express";

const router = Router();

router.get("/", (req, res) => {
  res.send("Users list");
});

export default router;

/routes/users/[id]/index.mjs:

import { Router } from "express";

const router = Router();

router.get("/", (req, res) => {
  const { id } = req.params;
  if (id) res.send("Users with id " + id);

index.mjs:

import express from "express";
import { RouteX } from "tralsejr/routex";

const app = express();

(async () => {
  // Load routes using RouteX
  await RouteX(app);

  // Start server
  const PORT = process.env.PORT || 3000;
  app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
  });
})();

Running

Run your Express project via CLI:

node index.js

or

node index.mjs

After running the server, you can now access the endpoints with format:

http://localhost:3000/users
http://localhost:3000/users/:id
http://localhost:3000/products
http://localhost:3000/invoice/customers
http://localhost:3000/invoice/merchants

NOTE: All files that is named index will be transformed as the endpoint following its folder name.

Ignoring Files

RouteX allows you to ignore specific files during the route loading process by starting filenames with an underscore (_). This feature is useful for excluding certain files from being automatically registered as routes in your Express application.

Example

Assume you have a directory structure like this:

project/
│
├── routes/
│ ├── _ignore.js
│ ├── users/
│ │ ├── index.js
│ │ └── [id]/
│ │ └── index.js
│ └── products.js

In this example, _ignore.js will not be loaded as a route, while routes defined in users/ and products.js will be automatically registered.

To utilize this feature effectively, ensure that any files you want to ignore are prefixed with _ in filenames.

Options Parameter

Debugging

RouteX supports a debug mode to provide more detailed error information during route loading. To enable debug mode, pass { debug: true } as an option when calling the RouteX function.

Example:

const express = require("express");
const { RouteX } = require("@tralsejr/routex");

const app = express();

(async () => {
  await RouteX(app, { debug: true });

  const PORT = process.env.PORT || 3000;
  app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
  });
})();

Make Report

Enabling makeReport param in options provides a summary of the routing setup process, including the total number of files processed, successfully read, ignored, errors encountered, routes loaded, and the overall success rate.

Example:

const express = require("express");
const { RouteX } = require("@tralsejr/routex");

const app = express();

(async () => {
  await RouteX(app, { makeReport: true });

  const PORT = process.env.PORT || 3000;
  app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
  });
})();

When makeReport is enabled in the options, RouteX generates a detailed report at the end of the routing process:

-------- RouteX Report --------
Total files processed: 10
- Successfully read: 8
- Ignored: 1
- Errors encountered: 1
--------------------------------
Routes loaded: 8
--------------------------------
Success rate: 90.00%
