Based on Koa2

快速搭建一个基于Koa2的应用

Example

// controller/user.c.js
const { Get, Post, Put, Delete BaseController } = require('pika-pikachu')

class UserController extends BaseController {

  @Get('/:id')
  async getById (ctx, next, { params: { id } }) {
    return await this.app.service.user.getById(id)
  }

  @Post('/')
  async insert (ctx, next, { body: { name, phone } }) {
    return await this.app.service.user.insert({ name, phone })
  }

  @Put('/:id')
  async updateById (ctx, next, { params: { id }, body: { name, phone } }) {
    return await this.app.service.user.updateById(id, { name, phone })
  }

  @Delete('/:id')
  async deleteById (ctx, next, { params: { id } }) {
    return await this.app.service.user.deleteById(id)
  }

}

module.exports = StarCoinController

// service/user.s.js
const { BaseService } = require('pika-pikachu')

class UserService extends BaseService {

  async getById (id) {
    return await DB.User.findById(id)
  }

  async insert (user) {
    return await DB.User.create(user)
  }

  async updateById (id, user) {
    return await DB.User.update(user, {
      where: { id }
    })
  }

  async deleteById (id) {
    return await DB.User.destroy({ where: { id } })
  }

}

// models/user.js
class User {

    return {
      paranoid: true
