@pricking/core v0.0.10

pricking-koa

a simple node framework based on koa2, in order to improve development efficiency.

WARNING: now only as an api server.

focus

rootPath is application root directory

1. The rootPath must contain controllers folder to load router.
2. if want add extra middlewares, you can add middlewares folder in rootPath.

Necessary directory convention specification

src
├── controllers # use decorator to define router
├── extends
│   └── context.ts # append extra property to ctx
└── middlewares # custom middlewares

about extra middleware

Don't design middleware that depends on execution order.(if necessary, only export a compose middleware)

It's worth mentioning that the middleware loading will traverse every possible file under the folder.

decorator

how to use it?

import { Controller, Description, Get } from 'pricking-koa/dist/utils/decorator';
import BaseController from 'pricking-koa/dist/controllers/BaseController';

// path pattern -> ${controllerPath}/*
@Controller('/v3/books')
class AnalyseController extends BaseController {
  @Index(['/', '(.*)']) // (.*) -> https://github.com/koajs/router/blob/master/history.md
  @Description()
  async index() {
    /** WARNING: should add plugin */
    this.ctx.render('book/index.ejs', { currentTime: Date.now() });
  }

  // path pattern -> ${controllerPath}/api/${subPath}
  // path register -> /v3/books/api/info
  // as same as @Post, @Delete, @Put
  @Get('/info')
  @Description('getBookInfo')
  async getBookInfo() {
    this.ctx.success({});
  }

  @Post('/search')
  @Description('search')
  async searchBook() {
    this.ctx.success({});
  }

  @Get('/origin')
  @Description('getBookOriginDetail')
  async getBookOriginDetail() {
    this.ctx.success({});
  }
}

export = AnalyseController;

import { PrickingApplication } from 'pricking-koa';

new PrickingApplication({
  // framework will auto load route from <ROOT>/controllers
  rootPath: __dirname,
  port: 3002,
  env: 'dev',
  debug: true,
});

middleware

export = (options: IOptions) => async (ctx, next) => {
  console.log(options.env);
  console.log('hello');
  await next();
  console.log('end');
};

target

• all in ts
• debug in ts mode
• lint
• test
• clean middleware loader
• simple decorator to define route faster
• support @Index decorator
