tt-api-kit v0.0.1

API-Kit

Typescript utility KIT for Express apis, including sequelize tools.

available on NPM

Installation

npm i @d-lab/api-kit

Usage

• Add Error middleware to your App

import express from "express"

const app = express()
app.use(errorMiddleware)

• Declare API handler in your routes, removing Express from your Controllers logic

// from routes/user.route.ts
import {Router} from "express"
import {handle} from "../interfaces/api"

// your own controller
import UserController from "../controllers/user.controller"
import {validateRequest} from "../middleware"
const ctrl = new UserController()

const router = Router()
router.get("/users/:userId", handle.bind(ctrl.get))
router.post("/users", validateRequest(CreateRequest), handle.bind(ctrl.create))

export default router

• Compile your routes in /routes/index.ts

import userRouter from "./user.route"
const routers = [
  userRouter
]
export default routers

• Add routes to your App

import routers from "./routes"
app.use(routers)

• Create your Controllers
  • You can now consider your controllers as simple methods without considering Express anymore
  • The success response will be handled in the router and the possible errors will be handled by the error middleware when HttpException are thrown in your code

import {PathRequest, AuthBodyRequest} from "../interfaces/api"

export default class UserController {
    public get = async (req: PathRequest<GetRequest>): Promise<UserResponse> => {
        const params = req.params
        return {}
    }
    public create = async (req: BodyRequest<CreateRequest>): Promise<UserResponse> => {
        const body = req.body
        return {}
    }
}
