create application

import { MvcApplication, DefaultMvcMiddlewares, MvcModule, MvcServer } from '@mvx/mvc';

// 1. use MvcHostBuilder to boot application.
MvcApplication.run();

// 2. use bootstrap module to boot application

@MvcModule({
    // baseURL: __dirname,
    imports: [
        //...  you service, or controller, some extends module.
    ],
    debug: true
})
class MvcApi {
    constructor() {
        console.log('boot application');
    }
}


// 3. use MvcHostBuilder to boot application module.

@MvcModule({
    imports: [
        // ... /...  you service, or controller, some extends module.
        // DebugLogAspect
    ],
    middlewares: DefaultMvcMiddlewares,
    // bootstrap: MvcServer
})
class MvcApi {

}

MvcApplication.run(MvcApi);


//4. use bootstrap module to boot application by main.
@MvcModule({
    imports: [
        // ...
    ],
    // bootstrap: MvcServer,
    debug: true
})
class MvcApi {
    constructor() {
        console.log('boot application');
    }

    static main() {
        console.log('run mvc api...');
        MvcApplication.run(MvcApi);
    }
}

Define Model

• third ORM Model: Configuration ModelOptions in your config file. like:

{
    ...
    /**
     * model parser.
     *
     * @type {ModelOptions}
     * @memberof IConfiguration
     */
    modelParser?: Token<IModelParser>;
    ...
}

import { Model, Field } from '@mvx/mvc';

@Model
export class User {
    @Field
    name: string;
    @Field
    sex: string;
    @Field
    age: number;
}

@Model
export class AccountUser extends User {
    @Field
    account: string;
    @Field
    passwd: string;
}

@Model
export class ShoppingCart{
    @Field
    owner: User;
    ....
}

Define Middlewares

default setting load middlewares in your project folder /middlewares

import { Middleware, IMiddleware, IContext, MvcMiddleware, ForbiddenError } from '@mvx/mvc';
import { IContainer, Injectable } from '@tsdi/core';


@Middleware({
    name: 'log-test',
    after: MiddlewareTypes.BodyParser
})
export class Logger implements IMiddleware {

    constructor() {

    }

    async execute (ctx, next) {
        let start = Date.now();
        await next();
        const ms = Date.now() - start;
        console.log(`mylog: ${ctx.method} ${ctx.url} - ${ms}ms`);
        let end = new Date();
    }

}


@Middleware({ name: 'rightCheck', scope: 'route' })
export class RoleRightCheck extends MvcMiddleware {

    async execute(ctx: IContext, next: () => Promise<void>): Promise<void> {
        // let user = ctx.session.user;
        // todo check user right;
        console.log('check user right.......');
        let hasRight = true;
        if (hasRight) {
            await next();
        } else {
            throw new ForbiddenError();
        }
    }
}

Auth use @Authorization pointcut

• aop pointcut to to dynamic check the controller with @Authorization decorator, use your custom auth validation. eg.

@Aspect
export class YourSecrityAspect {
    // before AuthorizationAspect.authProcess check some.
    @Before(AuthorizationPointcut, 'authAnnotation')
    sessionCheck(authAnnotation: AuthorizationMetadata[], joinPoint: Joinpoint) {
        //TODO： you check by authAnnotation
    }
}

Define Controller

default setting load controllers in your project folder /controllers

• Each Controller action should return type ResultValue, also you can return base type or object, it deal with JsonResult.
• The action can be async or sync. Have provide FileResult, JsonResult, RedirectResult, ViewResult or mvc Middleware.
• Also, you can extend with BaseController, it has implements some mothod to create the ResultValue types.
• Model can auto create in action, it auto load value from request body.
• Restfull params or Query String params can auto set to Controller action(Controller method) via the name of param matched.
• Cors by @Cors decorator in class or method.
• Your can set some special middlewares for route via decorator: @Controller, @Put, @Post, @Get, @Delete, @Patch, @Head, @Route.

define as:

import { Controller, Get, Post, IContext, ContextToken,  RequestMethod, Model, Field, Cors } from '@mvx/mvc';
import { Inject } from '@tsdi/core';
import { Mywork } from '../bi/Mywork';
import { User } from '../models';

@Cors
// @Authorization()
@Controller('/users')
export class UserController {

    // @Inject(ContextToken)
    // context: IContext;
    constructor(private work: Mywork) {

    }

    @Get('')
    index() {
        console.log('home index invorked', this.work);
        return this.work.workA();
    }

    @Authorization()
    // @Cors([RequestMethod.Post])
    @Post('/add', ['your-auth-middleware', 'rightCheck'])
    async addUser(user: User, @Inject(ContextToken) ctx: IContext) {
        console.log('user:', user);
        console.log('request body', ctx.request.body);
        return this.work.save(user);
    }

    @Get('/sub')
    sub() {
        return this.work.workB();
    }

    @Cors
    // @Authorization()
    @Get('/:name')
    getPerson(name: string) {
        return this.work.find(name);
    }

    @Get('/find/:name')
    find(@Inject(ContextToken) ctx, name: string) {
        console.log(ctx);
        return this.work.find(name);
    }

    // match request query param name.
    @Get('/query')
    query(key: string, role: string, age?: number) {
        return { key: key, age: age, role: role }
    }

    @Get('/test/:id')
    parmtest(id: number) {
        if (id === 1) {
            return this.work.workA();
        } else if (id === 2) {
            return this.work.workB();
        } else {
            return 'notFound';
        }
    }

    @Post('/posttest/:id', ['rightAuth'])
    postTest(id: number) {
        return {
            id: id
        }
    }

}



@Controller('/')
export class HomeController extends BaseController {

    // @Inject(ContextToken)
    // context: IContext;
    constructor() {
        super();
    }

    @Get('')
    index(): ResultValue {
        return this.view('index.html');
    }

    @Get('/index2')
    home2(): ResultValue {
        return this.view('index2.html');
    }

    @Post('/goto/:pageName')
    gotoPage(pageName: string): ResultValue {
        return this.redirect( '/' + pageName);
    }
}

startup extension Service

imports class extends StartupService, will inovke your configure service code.

socket.io sample.

@Singleton
export class RealtimeService extends StartupService<MvcContext> {

    io: Server;

    @Inject(RootMessageQueueToken)
    queue: MessageQueue<MessageContext>;

    constructor() {
        super();
    }


    async configureService(ctx: MvcContext): Promise<void> {
        let logger = ctx.logManager.getLogger();
        logger.info('create socket server...');
        this.io = SockerServer(ctx.httpServer);
        this.io.on('connection', sock => {
            logger.info('socket client connected', sock.id);
        });
    }

}



@MvcModule({
    // port: 8000,
    imports: [
        IdentityModule,
        TypeOrmModule,
        RealtimeService
    ]
    // middlewares: DefaultMvcMiddlewares,
    // debug: true
})
class MvcApp {
    constructor() {
        console.log('boot application');
    }

    // static main() {
    //     console.log('run mvc api...');
    //     MvcApplication.run(MvcApp);
    // }
}

MvcApplication.run(MvcApp);

Define Model

• third ORM Model: register yourself module parser extends ModelParser.

• typeorm model use : @tsdi/typeorm-adapter

• default load module in ./models folder, with exp ['.\/models\/**\/*{.js,.ts}', '!.\/**\/*.d.ts']

• default load repositories in ./repositories folder, with exp ['.\/repositories\/**\/*{.js,.ts}', '!.\/**\/*.d.ts']

import { Model, Field } from '@mvx/mvc';

@Model
export class User {
    @Field
    name: string;
    @Field
    sex: string;
    @Field
    age: number;
}

@Model
export class AccountUser extends User {
    @Field
    account: string;
    @Field
    passwd: string;
}

@Model
export class ShoppingCart{
    @Field
    owner: User;
    ....
}

Define AOP

Auto load Aspect service from folder /aop in your project.

see simple demo

import { Aspect, Around, Joinpoint, Before } from '@tsdi/aop';

@Aspect
export class DebugLog {
    @Around('execution(*Controller.*)')
    log(joinPoint: Joinpoint) {
        console.log('aspect append log, method name:', joinPoint.fullName, ' state:', joinPoint.state, ' Args:', joinPoint.args ,  ' returning:', joinPoint.returning, ' throwing:', joinPoint.throwing);
    }

    @Before(/Controller.\*$/)
    Beforlog(joinPoint: Joinpoint) {
        console.log('aspect Befor log:', joinPoint.fullName);
    }
}
