How to use it
To use this project you need to pull the following project with the kickstart of a server
Models
In Domain Driven Development, we can also call it Repository. How to use it.
Routers
These are the Resources, the REST API. For example this:
import { RestController, GET, POST, PUT, DELETE } from 'base-server/router';
import { NotFoundError } from 'base-server/errors';
import AddressService from '../services/AddressService';
import AddressModel from '../models/AddressModel';
@RestController('/address')
export default class AddressRouter {
@GET('/:uuid')
async findAddress({ params }) {
const address = await AddressModel.find(params.uuid);
if (!address) throw new NotFoundError('Address not Found');
return address;
}
@POST('/')
async createAddress({ body }) {
const address = await AddressService.create(body);
return AddressModel.find(address.uuid);
}
@PUT('/:uuid')
async updateAddress({ params, body }) {
await AddressService.update(params.uuid, body);
}
@DELETE('/:uuid')
async deleteAddress({ params }) {
await AddressService.deleteAddress(params.uuid);
}
}
Sequelize
They are the Entities, the objects that are persisted on the database
import { DataTypes } from 'sequelize';
import State from './State';
const { BIGINT, STRING } = DataTypes;
const City = sequelize.define('City', {
id: { type: BIGINT, primaryKey: true, autoIncrement: true },
name: { type: STRING(256), allowNull: false },
}, {
timestamps: false,
tableName: 'city'
});
City.belongsTo(State, {
as: 'State',
foreignKey: 'state_id'
});
export default City;
Services
They have to keep the business logic
index.js
import Server from 'base-server/server';
import { join } from 'path';
const server = new Server({
migration: {
name: 'pipeu-event-schedule',
dir: join(__dirname, '..', 'db'),
},
});
// add requires to all your routers (compatible with Babel+Webpack)
require('./routers/MyRouter');
export default server;
