express-simplefile-router

Transparent and simple filesystem-based router for Express.

Think how easy it is to create new routes in PHP and how obvious is the list of routes for a typical project? This is what I wanted in Express.

Synopsis

1. npm install express-simplefile-router

2. Create api-handlers/user/hello.get.js in your project:

module.exports = (req, res) => {
  res.send("Hello world");
};

1. Mount routes in your server.js:

const expressSimpleFileRouter = require('express-simplefile-router');

const app = express();

// ...

app.use(
  '/api/',
  expressSimpleFileRouter({
    directory: 'api-handlers'
  })
);

const server = app.listen(1111);

1. Now you have a GET method handler on /api/user/hello/:

user:~$ curl http://localhost:1111/api/user/hello/
Hello world

Documentation

expressSimpleFileRouter()

Basically expressSimpleFileRouter() traverses a directory of files and mounts them as routes on an instance of Express.router(). Simple as that.

It accepts two deconstructed arguments:

• directory (required) which directory to travel looking for files ending in .post.js, .get.js, .delete.js, .put.js or .patch.js and mounting them as routes;
• prefix (default '/') string to prepend to all route paths when mounting on Express.router();

Route handler files

Every route handler file is a node module. Whatever you module.exports is supplied as second argument to Express.router() mount method (.post(), .get(), etc). So you can export either a standard handler (req, res) => {..., or an array of such. See test/one/two.get.js for the latter example.

Route handler file names are mapped to their route paths. I.e. api/auth/user.post.js becomes route /api/user/ that handles POST methods.

Development and maintenance

Tests: npm run test or mocha test.js.

Liner: npm run lint or eslint index.js.

TODO

• Imagine a simple way to handle REST arguments (/user/123)
• Write jsdoc for index.js
• Collect developers' feedback
• Publish JSONHandler and ValidateSchema and add write docs for them all
