fast-maker

fast-maker generate fastify.js route configuration using by directory structure.

Why fast-maker?

fastify.js already have excellent auto route mechanics using fastify-autoload. But why you have to use fast-maker?

• Zero cost in Run-Time.
• Static analysis: fast-maker generate TypeScript source code. Because it help to find error in compile-time, not runtime
• Flexable Routing: You can use like that: /person/[kind]-[id]/. It help to get id and kind of id, for example serial-number and id or db-pk and id, even if you can use regular expression.
• Unifying how route paths are built: fast-maker use the same mechanics as Next.js. Route paths using file-system cannot be developer-specific
• fast-maker support a beautiful cli-interface

Getting started

npx fast-maker init
npx fast-maker route

You can create configuration file using init command. And you can run route command, fast-maker generate route.ts file on your output directory in configuration file.

You can see this mechanics!

How it works?

fast-maker using TypeScript Compiler API. So fast-maker exactly know handler function and route option in each file.

The image below briefly shows how the directory is converted to route configurations.

Installation

npm i fast-maker --save-dev

Usage

You can see help from --help option.

# display help for each commands
npx fast-maker --help

# display help for route commands
npx fast-maker route --help

# display help for init commands
npx fast-maker init --help

Also you can see detail option here.

Routing

fast-maker has a file-system based route configuration. This concept borrowed from Next.js routing system. But one difference is that HTTP Method is separated by file-system.

HTTP Method

use file-system.

handlers/
├─ superheros/
│  ├─ [id]/
│  │  ├─ powers/
│  │  │  ├─ [id]/
│  │  │  │  ├─ delete.ts
│  │  │  │  ├─ get.ts
│  │  │  │  ├─ put.ts
│  │  │  ├─ post.ts
│  │  ├─ delete.ts
│  │  ├─ get.ts
│  │  ├─ put.ts
│  ├─ get.ts
│  ├─ post.ts

get, post, put, delete filename represent HTTP Method. Also you can use options, patch, head, all filename.

Route options

You can pass RouteShorthandOptions option like that,

// When not using a `fastify` instance, you can declare it as a variable like this
export const option: RouteShorthandOptions = {
  schema: {
    querystring: schema.properties?.Querystring,
    body: schema.properties?.Body,
  },
};

// When using the `fastify` instance, you can declare it as a function like this
export const option = (fastify: FastifyInstance): RouteShorthandOptions => {
  return {
    schema: {
      querystring: schema.properties?.Querystring,
      body: schema.properties?.Body,
    },
     preHandler: fastify.auth([
      fastify.allowAnonymous,
      fastify.verifyBearerAuth
    ]),
  };
};

You have to named export and variable name must be a option.

Route handler

You can pass route handler function like that,

import { FastifyRequest } from 'fastify';
import type { IReqSearchPokemonQuerystring, IReqSearchPokemonParams } from '../../interface/IReqSearchPokemon';

export async function handler(
  req: FastifyRequest<{ Querystring: IReqSearchPokemonQuerystring; Params: IReqSearchPokemonParams }>,
) {
  console.debug(req.query);
  console.debug(req.body);

  return 'hello';
}

You have to named export and variable name must be a handler. Also you can use arrow function and you can use any name under TypeScript function name rule, as well as type arguments perfectly applied on route configuration

Variable in Route Path

File or Directory name surrounded square bracket like that,

handlers/
├─ superheros/
│  ├─ [id]/
│  │  ├─ get.ts
│  │  ├─ put.ts

Multiple variable, No problem.

handlers/
├─ superheros/
│  ├─ [kind]-[id]/
│  │  ├─ get.ts

This route path access like that: curl http://localhost:8080/hero/marvel-ironman

That's it. fast-maker takes care of the rest.
