Documentation

Wait for next version

Installation

Generate new project with NextJS App Router (Page Router is not tested yet but it should work.)

npx create-next-app --use-yarn

Install this package

yarn add @ffsm/napi

Using

Using same NestJS.

Make project folder structure:

<project>/
|   |_public/
|   |  ...
|   |_src/
|   |   |_app/
|   |   |   |_api/
|   |   |   |   |_[[...v1]]
|   |   |   |   |   |_route.ts
|   |_package.json
|   |_tsconfig.json
|   |_eslint.config.mjs
|   |_postcss.config.mjs
|   |_yarn.lock
|   |_...

Register app for API.

// <project>/src/app/api/[[...v1]]/route.ts
import { NapiApplication } from "@ffsm/napi";
import { UserController } from "./modules/users/user.controller.ts"

// Remove methods that you does not using.
export const {
  GET,
  POST,
  PUT,
  PATCH,
  DELETE,
  HEAD,
  OPTIONS
} = NapiApplication.register({
  prefix: "v1",
  configs: [], // For load env same @nestjs/config
  controllers: [
    UserController,
  ],
});

Make controller

// <project>/src/app/api/[[...v1]]/modules/users/user.controller.ts

import { Controller, Get, Params } from "@ffsm/napi";

@Controller()
export class UserController {

  @Get()
  getUsers() {
    return [
      { id: 1, name: "User 1" },
    ];
  }

  @Get(":userId")
  getUserById(@Params() params: { userId: string }) {
    return {
      params,
    };
  }
}

Update tsconfig.json

{
  ...
  "compilerOptions": {
    ...
    "esModuleInterop": true,
    "strictPropertyInitialization": false,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    ...
  },
  ...
}

OR extends @ffsm/napi/tsconfig.napi.json

{
  "extends": "@ffsm/napi/tsconfig.napi.json",
  "compilerOptions": {
    ...
  },
  ...
}

API

Decorators

• Controller class: Controller
• Controller methods: Get, Post, Put, Patch, Delete, Options, Head, HttpStatus, HttpText, SetHeaders.
• Controller method params: Params, Body, Query, Res, Req, Headers, Cookies, Files, Session

In this version, initialize service inside constructor of controller.

Next version will support decorator Injectable() to make DI for service.

WIP

• @Controller(): Done (will apply Injectable when it ready)
• @Get(), @Post(), ...: Will support more options.
• @Injectable(): In-Progress
• @ffsm/napi-typeorm: In-Progress
• ExceptionFilter: In-Progress
• PipeTransform: In-Progress
• CanActivate: In-progress
• @ffsm/napi-swagger: To-Do
