Express FS

Express FS bootstraps your express' app routing based on your source code location, enforcing a neat project structure and removing the need for explicit routing definition.

Installing

npm install @luzzif/express-fs

or

yarn add @luzzif/express-fs

How to use

The library's basic concept block is the fs-route.

In Express FS a fs-route is a simple Node module which exports a handler and some middleware functions (those are the same entities that you would normally define in express in order to specify a route).

An example of an fs-route can be something like this:

// route.js

export const handler = (request, response, next) => next();
export const middleware = (request, response, next) => next();

// Alternatively, multiple middleware functions can be specified
// like this:
// export const middleware = [
//    (request, response, next) => next(),
//    (request, response, next) => next()
// ];

The other aspects of an fs-route aside for the implementation are the path and the method: those are simply deducted by the location of the fs-route module.

The location should in fact reflect the wanted fs-route's path, while the last part of the location should indicate the wanted method.

Some examples to clarify the concept (the route is expressed in the format <method>@<path>):

• a/route/path/get/index.js => GET@/a/route/path
• foo/bar/post.js => POST@/foo/bar
• patch.js => PATCH@/

In order to make Express FS register one or more fs-routes, simply pass the app's root (typically __dirname) and the glob referencing those Node modules containing an fs-route definition to the fsRouter function, and pass the result to express' use.

Example:

// server.js

const express = require("express");
const { fsRouter } = require("@luzzif/express-fs");

const app = express().use(fsRouter(__dirname, "api/**/index.js"));

The snippet above registers all those fs-routes located under the project's root directory api.

By leveraging this approach, Express FS completely eliminates the need for any routing setup and enforces a clear, straight-forward project structure.
