wd-express-fs-router

A simple filesystem-based router for express, made for weedocs project.

Usage:

In your server script:

// index.js

const express = require('express');
const app = express();
const router = require('wd-express-fs-router');
// [...]
router('your/app/folder', app);
// [...]
app.listen(3000); 

Directory Structure and File naming

The route files must be named following this especification: [route].[httpMethod].[extension]

• [route]: The route path. You can declare params using : at start of name. ex: :post_id.get.js;
• [httpMethod]: The http method in lower case. get,post,put,delete;
• [extension]: The file extension .js or .ts.

This example assumes you have a directory src/routes next to the index.js file.

src/routes/
├─ posts/
│ └─ :id.get.js
│ └─ :id.put.js
│ └─ index.get.js
│ └─ index.post.js

The following routes will be generated:

GET /posts --> src/routes/posts/index.get.js
POST /posts --> src/routes/posts/index.post.js
GET /posts/:id --> src/routes/posts/:id.get.js
PUT /posts/:id --> src/routes/posts/:id.put.js

You also can create create directories to compose the route path.

├─ posts/
│ └─ :id/
│    └─ comments.get.js

 //  GET post/:id/comments

All route files must exports a function with the express route handler. Like this:

module.exports = function (req, res) {
   // res.json({  });
}

Middlewares

The router also supports Middlewares. You can declare middlewares creating files named _middleware.js. This files must exports a function with the middleware handler.

// _middleware.js
module.exports = function (req, res, next) {
   // do something or:
   next();
}

All middlewares will be inherited from current and all parents directories .

src/routes/
├─ posts/
│ └─ _middleware.js
│ └─ index.get.js 
│        // will pass through /posts/_middleware.js 
│ └─ comments
│    └─ index.get.js 
│          // will pass through /posts/_middleware.js 
│          // and posts/comments/_middleware.js
