Hapi-filesystem-router NPM

hapi-filesystem-router

Filesystem based routing for Hapi.

Package is usable but new. It makes an effort to follow semantic versioning witch means backward incompatible changes will be introduced only in major releases. But removing "^" from all your production dependencies is a good practice anyway.

It allows you to add routes based on directory structure.

This package is made for those who have relatively deeply nested routing on their sites and want stricter project structure.

Simple example

Following directories structure will add 3 routes.

routes
- get.ts
- item
  - {id}
    - get.ts
    - post.ts

import { attachRoutes } from 'hapi-filesystem-router';
// ...
const server = Hapi.server({});

await attachRoutes(server);

await server.start();
// ...

Results in

method	path
GET	/
GET	/item/{id}
POST	/item/{id}

More complex example

You can have multiple roots and specify different default configurations for them. As example you can use it for separating routes that require authorization/authentication.

routes
- private
  - item
    - {id}
      - get.ts
      - post.ts
- public
  - get.ts
  - item
    - {id}
      - get.ts
      - post.ts

import { attachRoutes } from 'hapi-filesystem-router';
// ...
const server = Hapi.server({});

await attachRoutes(server, 'routes/public');
await attachRoutes(server, 
  'routes/private', // path to the root of routes 
  'protected', // prefix that will be added to actual route (see results)
  {
    options: {
      auth: {
        scope: ['admin'],
        strategy: 'session',
      },
    },
  });

await server.start();
// ...

Results in

method	path	auth	scope
GET	/	none	none
GET	/item/{id}	none	none
POST	/item/{id}	none	none
GET	/protected/item/{id}	session	admin
POST	/protected/item/{id}	session	admin

Handler

File with handler should be named as any http method except for 'head' and export default hapi route object.

// routes/item/{id}/post.ts 
import Joi from 'joi';
import { FSRM } from 'hapi-filesystem-router';

const route: FSRM<{
  payload: { title: string };
  params: { id: string };
}> = {
  options: {
    validate: {
      payload: Joi.object({
        title: Joi.string().length(255),
      }),
      params: Joi.object({
        id: Joi.string(),
      }),
    },
  },
  handler: async (request, h) => {
    const { title } = request.payload;
    const { id } = request.params;
    return {
      id,
      title,
      updatedAt: new Date().toISOString(),
    };
  },
};

export default route;
