Introduction

totea is a nodejs framework based on express, using decorators to define routing and middleware. Features overview:

• javascript: Existing frameworks that use decorators all use typescript by default, totea can be used in javascript, only need to introduce plugin-proposal-decorators;
• Simple and efficient: totea provides less than 20 decorator functions, but it can support a variety of complex usage scenarios;
• Easy to integrate: Totea uses express as a web server. We have not modified any underlying logic, which means that the methods and plugins that can be used in express can also be used in totea.

Example

Let's create a simple user service, including the addition, deletion, modification, and checking of users, and then create a secondary route to obtain the tag list of users.

const { Server, Get, Post, Delete, Put, Middleware, Controller，Params } = require('@totea/core')

// add a sub-route
@Controller('tag')
class tagController {
  @Get('/list')  // GET /tag/list
  getTag() {}
}

@Server({
	port: 4000, // set port to 4000
	controller: [tagController]  // provide it to Server
})
@Middleware((req, res, next) => {   // add a global middleware
	next()
})
class Service {
  @Get('/user')  // GET /user
  getUser() {}

  @Get('/user/:id') // GET /user/${id}
  @Middleware((req, res, next) => {  // add a private middleware
	next()
  })
  getUserById({ params }) {}

  @Post('/user')  // POST /user
  insertUser({ body }) {}

  @Delete('/user/:id')  // DELETE /user/${id}
  // add a params filter: the req.params.id must set and length = 10
  @Params(params => params.id && params.id.length === 10)
  deleteUserById({ params }) {}

  @Put('/user/:id') // PUT /user/${id}
  modifyUserById({ params, body }) {}
 }

const service = new Service()
service.start()

This is all the code, isn't it simple?

Installation and use

# install totea
npm i @totea/core

# Install and configure babel
npm i @babel/core @babel/node @babel/plugin-proposal-decorators

# If there is already a babel configuration, add a decorator plugin
# If not, create a babel configuration file in the project root directory and write the following:
module.exports = {
  plugins: [
    ["@babel/plugin-proposal-decorators", {legacy: true }]
  ],
};

# Use babel-node to run and debug your code
npx babel-node index.js
