Node File Router

A powerful file-based routing for Node.js.

It simplifies the creation and organization of API services. You can effortlessly map your project's file structure to your API endpoints, enabling a clear and maintainable codebase.

Overview

Imagine you have a project with the following structure:

api/
├── profile/
│   ├── middlware.ts - middleware for profile
│   └── orders.[post].ts - methods in any filenames
├── catalog/
│   └── [[...tags]].ts - several segments
├── collection/
│   └── [cid]/ - slugs in folders
│       └── products/
│           └── [pid].ts - slugs in files
├── index.ts - root
├── middleware.ts - middleware for all routes
└── _404.ts - not found response

Node File Router will automatically map it to your API endpoints:

[POST]: /profile/orders → /api/profile/orders.[post].ts
/catalog/men/black/denim → /api/catalog/[[...tags]].ts
/collection/77/products/13 → /api/collection/[cid]/products/[pid].ts
/ → index.ts

Some examples of how your file handlers can be written:

Methods in a file

export default {
  get(req, res, routeParams) {},
  post(req, res, routeParams) {},
  patch(req, res, routeParams) {},
}

Single response function

export default function (req, res, routeParams) {}

Middlewares chain

export default [
  useErrorHandler,
  useLogger,
  useAuthGuard,
];

Classes

export default class Resource {
  get(req, res, routeParams) {}
  
  post(req, res, routeParams) {}
  
  patch(req, res, routeParams) {}
}
