Parizvino, iyo REST API yave chiyero chekuvandudzwa kwewebhu application, ichibvumira budiriro kukamurwa kuita zvikamu zvakazvimirira. Akasiyana siyana ane mukurumbira masisitimu akadai seAngular, React, Vue uye mamwe ari kushandiswa kuUI. Backend Developers vanogona kusarudza kubva kwakasiyana siyana mitauro uye masisitimu. Nhasi ndinoda kutaura pamusoro pegadziriro yakadai se NestJS. Tapinda TestMace Isu tinoshingaira kuishandisa kumapurojekiti emukati. Kushandisa nest uye package @nestjsx/crud, isu tichagadzira iri nyore CRUD application.

Nei NestJS

Munguva pfupi yapfuura, akawanda akawanda emashure emashure akaonekwa munharaunda yeJavaScript. Uye kana maererano nekushanda ivo vachipa zvakafanana kugona kuNest, saka muchinhu chimwe inokunda zvechokwadi - uku ndiko kuvaka. Aya anotevera NestJS maficha anotendera iwe kuti ugadzire maindasitiri maapplication uye kukura kwekukura kuzvikwata zvikuru:

• uchishandisa TypeScript semutauro mukuru wekusimudzira. Kunyange zvazvo NestJS inotsigira JavaScript, kumwe kushanda kunogona kusashanda, kunyanya kana tiri kutaura nezvepakeji yechitatu;
• kuvapo kweDI mudziyo, iyo inokutendera iwe kuti ugadzire zvakasununguka zvakabatanidzwa zvikamu;
• Iko kushanda kwegadziriro pachayo yakakamurwa kuva zvikamu zvakasununguka zvinoshandurana. Semuenzaniso, pasi pehodhi segadziriro inogona kushandiswa se ratidza, uye fastify, kushanda nedatabase, dendere kunze kwebhokisi rinopa zvisungo kune typorm, mongoose, sequelize;
• NestJS ipuratifomu agnostic uye inotsigira REST, GraphQL, Websockets, gRPC, nezvimwe.

Iyo dhizaini pachayo inofemerwa neAngular frontend framework uye conceptually ine zvakawanda zvakafanana nazvo.

Kuisa NestJS uye Kuendesa Chirongwa

Nest ine pasuru dendere/ cli, iyo inokutendera iwe kukurumidza kuendesa yakakosha application framework. Ngatiisei pasuru iyi pasi rose:

npm install --global @nest/cli

Mushure mekuisa, isu tichagadzira iyo yakakosha sisitimu yekushandisa yedu ine zita nest-rest. Izvi zvinoitwa uchishandisa murairo nest new nest-rest.

Kugadzira basa ne database

Ndakasarudza PostrgreSQL seDBMS yechinyorwa ichi. Hapana kupokana pamusoro pezvandinoda; mumaonero angu, iyi ndiyo DBMS yakakura kwazvo, ine zvese zvinodiwa. Sezvambotaurwa, Nest inopa kubatanidzwa nemapakeji akasiyana siyana kushanda nemadhatabhesi. Nokuti Sezvo sarudzo yangu yakawira paPostgreSQL, zvingave zvine musoro kusarudza TypeORM seORM. Ngatiisei mapakeji anodiwa ekubatanidza nedatabase:

yarn add typeorm @nestjs/typeorm pg

Kurongeka, chii chimwe nechimwe pasuru inodiwa kune:

1. typeorm - pasuru yakananga kubva kuORM pachayo;
2. @nestjs/typeorm - TypeORM package yeNestJS. Inowedzera ma modules ekuunza kunze mumapurojekiti modules, pamwe chete neseti yevabatsiri vanoshongedza;
3. pg - mutyairi wekushanda nePostgreSQL.

Zvakanaka, mapakeji akaiswa, ikozvino iwe unofanirwa kuvhura dhatabhesi pachayo. Kuendesa dhatabhesi, ini ndichashandisa docker-compose.yml ine zvinotevera zvirimo:

docker-kunyora.yml

version: '3.1'

services:
  db:
    image: postgres:11.2
    restart: always
    environment:
      POSTGRES_PASSWORD: example
    volumes:
      - ../db:/var/lib/postgresql/data
      - ./postgresql.conf:/etc/postgresql/postgresql.conf

  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

Sezvauri kuona, iyi faira inogadzirisa kuvhurwa kwemidziyo miviri:

1. db igaba rine zvakanangana nedatabase. Kwatiri, postgresql vhezheni 11.2 inoshandiswa;
2. adminer-database maneja. Inopa webhu interface yekuona uye kutonga dhatabhesi.

Kuti ushande netcp yekubatanidza, ini ndakawedzera inotevera config.

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, run "pg_ctl reload", or execute
# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
# require a server shutdown and restart to take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some parameters can be changed at run time
# with the "SET" SQL command.

Ndizvo chete, unogona kutanga midziyo nemirairo docker-compose up -d. Kana mune yakaparadzana koni ine rairo docker-compose up.

Saka, mapakeji akaiswa, dhatabhesi yakatangwa, chasara kuita kuti vave shamwari. Kuti uite izvi, unofanirwa kuwedzera iyo inotevera faira kumudzi weprojekiti: ormconfig.js:

ormconfig.js

const process = require('process');
const username = process.env.POSTGRES_USER || "postgres";
const password = process.env.POSTGRES_PASSWORD || "example";
module.exports = {
"type": "postgres",

"subscribers": ["subscriber/**/*.ts", "dist/subscriber/**/.js"],
"cli": {
"entitiesDir": "src",
"migrationsDir": "migrations",
"subscribersDir": "subscriber"
}
}

Iyi gadziriso ichashandiswa kune cli typeorm.

Ngatitarisei kugadzirisa uku mune zvakadzama. Pamitsetse 3 uye 4 tinowana zita rekushandisa uye password kubva kune zvakatipoteredza zvinosiyana. Izvi zviri nyore kana uine akati wandei nharaunda (dev, nhanho, prod, nezvimwe). Nekusagadzikana, zita rekushandisa ndiro postgres uye password muenzaniso. Iyo yakasara yegadziriso idiki, saka isu tinongotarisa pane anonyanya kufadza paramita:

• synchronize - Inoratidza kana iyo schema yedatabase ichifanirwa kugadzirwa otomatiki kana application yatanga. Ngwarira nesarudzo iyi uye usashandise mukugadzira, zvikasadaro iwe ucharasikirwa nedata. Iyi sarudzo yakanakira kana uchigadzira uye kugadzirisa application. Seimwe nzira kune iyi sarudzo, unogona kushandisa murairo schema:sync kubva kuCLI TypeORM.
• dropSchema - gadzirisa schema pese painotangwa. Kungofanana neyakapfuura, iyi sarudzo inofanirwa kushandiswa chete panguva yekuvandudza uye kugadzirisa kwekushandisa.
• masangano - inzira dzipi dzekutsvaga tsananguro dzemhando. Ndokumbira utarise kuti kutsvaga nemask kunotsigirwa.
• cli.entitiesDir ndiro dhairekitori uko mamodheru akagadzirwa kubva kuTypeORM CLI anofanirwa kuchengetwa nekusarudzika.

Kuti isu tikwanise kushandisa ese maficha eTypeORM mune yedu Nest application, isu tinofanirwa kuunza moduli. TypeOrmModule в AppModule. Avo. wako AppModule zvicharatidzika seizvi:

app.module.ts

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { TypeOrmModule } from '@nestjs/typeorm';
import * as process from "process";
const username = process.env.POSTGRES_USER || 'postgres';
const password = process.env.POSTGRES_PASSWORD || 'example';
@Module({
imports: [
TypeOrmModule.forRoot({

synchronize: true,
}),
],
controllers: [AppController],
providers: [AppService],
})
export class AppModule {}

Sezvaungave waona, iyo nzira forRoot iyo imwechete gadziriso yekushanda nedatabase inotamiswa sezviri mune ormconfig.ts faira

Kubata kwekupedzisira kunoramba - wedzera akati wandei mabasa ekushanda neTypeORM mu package.json. Icho chokwadi ndechekuti iyo CLI yakanyorwa mujavascript uye inomhanya munzvimbo ye nodejs. Nekudaro, ese edu mamodheru uye kutama anozonyorwa mukunyora. Naizvozvo, zvinodikanwa kushandura kutama kwedu uye modhi tisati tashandisa iyo CLI. Kune izvi isu tinoda iyo ts-node package:

yarn add -D ts-node

Mushure meizvozvo, wedzera iyo inodiwa mirairo ku package.json:

"typeorm": "ts-node -r tsconfig-paths/register ./node_modules/typeorm/cli.js",
"migration:generate": "yarn run typeorm migration:generate -n",
"migration:create": "yarn run typeorm migration:create -n",
"migration:run": "yarn run typeorm migration:run"

Murairo wekutanga, typeorm, inowedzera ts-node wrapper kuti imhanye TypeORM cli. Iyo yasara mirairo mapfupi mapfupi ayo iwe, semugadziri, uchashandisa anenge mazuva ese:
migration:generate - kugadzira kutama kunoenderana nekuchinja kwemamodheru ako.
migration:create - kugadzira kutama kusina chinhu.
migration:run - kutanga kutama.
Zvakanaka, ndizvo zvazviri, isu takawedzera mapakeji anodiwa, takagadzirisa application kuti ishande nedhatabhesi zvese kubva kucli uye kubva kune iyo application pachayo, uye zvakare yakatanga DBMS. Yave nguva yekuwedzera logic kune yedu application.

Kuisa mapakeji ekugadzira CRUD

Uchishandisa Nest chete, unogona kugadzira API inobvumidza iwe kugadzira, kuverenga, kugadzirisa uye kudzima chinhu. Iyi mhinduro ichave inoshanduka sezvinobvira, asi mune dzimwe nguva inenge isisina basa. Semuenzaniso, kana iwe uchida kukurumidza kugadzira prototype, iwe unogona kazhinji kupa kuchinjika kwekumhanya kwekusimudzira. Mazhinji masisitimu anopa mashandiro ekugadzira CRUD nekutsanangura iyo data modhi yechimwe chinhu. Uye Nest haina mutsauko! Kushanda uku kunopihwa nepakeji @nestjsx/crud. Kugona kwayo kunonakidza kwazvo:

• nyore kuisa uye kugadzirisa;
• DBMS kuzvimiririra;
• mutauro wemubvunzo une simba nekugona kusefa, paginate, kuronga, kurodha hukama uye nested masangano, caching, nezvimwe;
• package yekugadzira zvikumbiro kumberi-kumagumo;
• nyore kudarika nzira dzemutongi;
• small config;
• swagger zvinyorwa zvinotsigira.

Iko kushanda kwakakamurwa kuva akati wandei mapakeji:

• @nestjsx/crud - iyo yakakosha package iyo mugadziri anopa Crud() yekugadzira nzira, kugadzirisa uye kusimbiswa;
• @nestjsx/crud-request - pasuru inopa muvaki wemubvunzo / parser kuti ishandiswe kudivi remberi;
• @nestjsx/crud-typeorm - pasuru yekubatanidza neTypeORM, ichipa iyo yakakosha TypeOrmCrudService sevhisi neCRUD nzira dzekushanda nemasangano ari mudhatabhesi.

Muchidzidzo ichi tichada mapakeji denderejsx/crud uye denderejsx/crud-typeorm. Kutanga, ngatidziise

yarn add @nestjsx/crud class-transformer class-validator

Packages kirasi-shanduko и class-validator muchikumbiro ichi chinodiwa kuti pave netsanangudzo inozivisa yemitemo yekushandura mamiriro emuenzaniso uye kusimbisa zvikumbiro zvinouya, zvichiteerana. Aya mapakeji anobva kumunyori mumwechete, saka mainterface akafanana.

Kuitwa kwakananga kweCRUD

Tichatora runyorwa rwevashandisi semuenzaniso wemuenzaniso. Vashandisi vachava neminda inotevera: id, username, displayName, email. id - auto-incrementing munda, email и username - minda yakasiyana. Zviri nyore! Chasara kuita zano redu nenzira yeNest application.
Kutanga iwe unofanirwa kugadzira module users, ndiani achava nebasa rekushanda nevashandisi. Ngatishandisei cli kubva kuNestJS uye tiite murairo mumudziyo wedhairekitori reprojekiti yedu nest g module users.

nest g module vashandisi

dmitrii@dmitrii-HP-ZBook-17-G3:~/projects/nest-rest git:(master*)$ nest g module users
CREATE /src/users/users.module.ts (82 bytes)
UPDATE /src/app.module.ts (312 bytes)

Mune ino module isu tichawedzera entities folda, apo isu tichava nemhando dzeiyi module. Kunyanya, ngatiwedzerei pano faira user.entity.ts ine tsananguro yemhando yemushandisi:

user.entity.ts

import { Column, Entity, PrimaryGeneratedColumn } from 'typeorm';
@Entity()
export class User {
@PrimaryGeneratedColumn()
id: string;
@Column({unique: true})
email: string;
@Column({unique: true})
username: string;
@Column({nullable: true})
displayName: string;
}

Kuti iyi modhi "ionekwe" nekushandisa kwedu, zvinodikanwa mune module UsersModule import TypeOrmModule zvinotevera zvirimo:

vashandisi.module.ts

import { Module } from '@nestjs/common';
import { UsersController } from './controllers/users/users.controller';
import { UsersService } from './services/users/users.service';
import { TypeOrmModule } from '@nestjs/typeorm';
import { User } from './entities/user.entity';
@Module({
controllers: [UsersController],
providers: [UsersService],
imports: [
TypeOrmModule.forFeature([User])
]
})
export class UsersModule {}

Ndiko kuti, pano tinopinza TypeOrmModule, apo senzira parameter forFeature Isu tinoratidza runyorwa rwemhando dzine chekuita neiyi module.

Chinosara ndechekugadzira chikamu chinowirirana mudhatabhesi. Iyo nzira yekutama inoshandira izvi zvinangwa. Kuti ugadzire kutama kunoenderana nekuchinja kwemamodheru, unofanirwa kumhanya kuraira npm run migration:generate -- CreateUserTable:

spoiler title

Migration /home/dmitrii/projects/nest-rest/migrations/1563346135367-CreateUserTable.ts has been generated successfully.
Done in 1.96s.

Hatina kufanira kunyora kutama nemaoko, zvese zvakaitika nemashiripiti. Hachisi chishamiso here ichi! Zvisinei, handizvo zvoga. Ngatitarisei iyo yakagadzirwa migration file:

1563346135367-CreateUserTable.ts

import {MigrationInterface, QueryRunner} from "typeorm";
export class CreateUserTable1563346816726 implements MigrationInterface {

}
public async down(queryRunner: QueryRunner): Promise<any> {
await queryRunner.query(`DROP TABLE "user"`);
}
}

Sezvauri kuona, kwete chete nzira yekutanga kutama yakangogadzirwa, asiwo nzira yekudzosera kumashure. Fantastic!
Chasara kuburitsa kutama uku. Izvi zvinoitwa nemurairo unotevera:

npm run migration:run.

Ndizvozvo, ikozvino schema shanduko dzatamira kune database.
Tevere, isu tichagadzira sevhisi ichave nebasa rekushanda nevashandisi uye nekugara nhaka kubva TypeOrmCrudService. Iyo repository yechikamu chekufarira inofanirwa kupfuudzwa kune parameter yemubereki muvaki, kwatiri isu. User repository.

vashandisi.service.ts

import { Injectable } from '@nestjs/common';

import { Repository } from 'typeorm';
@Injectable()
export class UsersService extends TypeOrmCrudService<User>{
constructor(@InjectRepository(User) usersRepository: Repository<User>){
super(usersRepository);
}
}

Tichada sevhisi iyi mu controller users. Kuti ugadzire controller, nyora iyo console nest g controller users/controllers/users

nest g controller vashandisi/vatongi/vashandisi

UPDATE /src/users/users.module.ts (188 bytes)

Ngativhure controller iyi toigadzirisa kuti tiwedzere mashiripiti denderejsx/crud. Pakirasi UsersController Ngatiwedzerei decorator seizvi:

@Crud({

})

Crud mugadziri anowedzera kune mutongi nzira dzinodiwa dzekushanda nemuenzaniso. Mhando yemhando inoratidzwa mumunda model.type decorator zvigadziriso.
Nhanho yechipiri ndeyekushandisa iyo interface CrudController<User>. "Yakaungana" controller kodhi inoita seizvi:

Uye zvose! Iye zvino mutongi anotsigira seti yese yekushanda nemuenzaniso! Musanditenda? Ngatiedzei application yedu mukuita!

Kugadzira Query Script muTestMace

Kuedza sevhisi yedu tichashandisa IDE kushanda neAPI TestMace. Sei TestMace? Kana ichienzaniswa neyakafanana zvigadzirwa, ine zvinotevera zvakanakira:

• basa rine simba rine zvinoshanduka. Parizvino, kune marudzi akawanda emhando dzakasiyana-siyana, imwe neimwe inobata basa rakasiyana-siyana: rakavakwa-mukati, rakasiyana-siyana, rakasiyana-siyana. Imwe neimwe yakasiyana ndeye node ine tsigiro yenhaka nzira;
• Gadzira zvinyorwa zviri nyore pasina hurongwa. Izvi zvichakurukurwa pazasi;

• autocompletion, syntax inosimudzira, kusiyanisa kukosha kujekesa;
• API tsananguro yerutsigiro nekugona kuunza kubva kuSwagger.

Ngatitangei server yedu nemirairo npm start uye edza kuwana rondedzero yevashandisi. Rondedzero yevashandisi, tichitonga neyedu controller kumisikidzwa, inogona kuwanikwa kubva kune url localhost:3000/users. Ngatiite chikumbiro kune iyi url.
Mushure mekumhanya TestMace unogona kuona interface seizvi:

Kumusoro kuruboshwe kune muti wepurojekiti une node yemidzi purojekiti. Ngatiedzei kugadzira chikumbiro chekutanga kuwana runyorwa rwevashandisi. Nokuda kweizvi tichagadzira RequestStep node Izvi zvinoitwa mune yemukati menyu yeProjekti node Wedzera node -> Chikumbiro Nhanho.

Mumunda we URL, isa localhost:3000/users uye mhanyisa chikumbiro. Isu tichagamuchira kodhi 200 ine isina chinhu array mune yekupindura muviri. Zvinonzwisisika, isu hatisati tawedzera chero munhu.
Ngatigadzire script inozosanganisira matanho anotevera:

1. kugadzira mushandisi;
2. kukumbira id yemushandisi achangogadzirwa;
3. kudzima nemushandisi id yakagadzirwa mudanho rekutanga.

Saka, handei. Kuti zvive nyore, ngatigadzire node yakafanana forodha. Chaizvoizvo, iyi ingori folda umo isu tichachengeta iyo yese script. Kuti ugadzire Folder node, sarudza Project kubva pane yemukati menyu yenode Wedzera node -> Folder. Ngatishevedze node cheki-gadzira. Mukati me node cheki-gadzira Ngatigadzirei chikumbiro chedu chekutanga kugadzira mushandisi. Ngatishevedze iyo ichangobva kugadzirwa node kugadzira-mushandisi. Ndokunge, panguva ino iyo node hierarchy ichaita seizvi:

Handei kune yakavhurika tab kugadzira-mushandisi node. Ngatiisei maparameter anotevera echikumbiro:

• Rudzi rwekukumbira - POST
• URL - localhost:3000/users
• Muviri - JSON ine kukosha {"email": "[email protected]", "displayName": "New user", "username": "user"}

Ngatizadzise chikumbiro ichi. Chikumbiro chedu chinoti rekodhi rakagadzirwa.

Zvakanaka, ngationgororei chokwadi ichi. Kuti ushande neid yemushandisi akagadzirwa mumatanho anotevera, iyi parameter inofanirwa kuchengetwa. Iyo michina yakakwana kune iyi. dynamic variables. Ngatishandisei muenzaniso wedu kutarisa kuti tingashanda sei navo. Mune iyo yakakamurwa tebhu yemhinduro, padivi peiyo id node mune yemukati menyu, sarudza chinhu Ipa kuchinjika. Mubhokisi rebhokisi unofanirwa kuseta zvinotevera paramita:

• Node - mune ipi yemadzitateguru kugadzira shanduko ine simba. Ngatisarudzei cheki-gadzira
• Anochinja zita - zita rekuchinja uku. Ngatifonerei userId.

Heino maitiro ekugadzira shanduko ine simba inotaridzika sei:

Ikozvino, pese pese mubvunzo uyu paunoitwa, kukosha kweiyo dynamic variable inovandudzwa. Uye nokuti dynamic variables inotsigira mashandiro enhaka yehierarchical, inoshanduka userId zvichawanikwa muvazukuru cheki-gadzira node yechero nhanho yekugara.
Iyi shanduko ichave yakakosha kwatiri muchikumbiro chinotevera. Sezvineiwo, isu tichakumbira mushandisi achangogadzirwa.
