🚀 Quick start

npm init -y
npm install simple-boot-http-server
tsc --init --experimentalDecorators --emitDecoratorMetadata

import {HttpServerOption} from 'simple-boot-http-server/option/HttpServerOption';
import {SimpleBootHttpServer} from 'simple-boot-http-server';
import {Sim} from 'simple-boot-core/decorators/SimDecorator';
import {Route, Router} from 'simple-boot-core/decorators/route/Router';
import {GET} from 'simple-boot-http-server/decorators/MethodMapping';
import {Mimes} from 'simple-boot-http-server/codes/Mimes';
import {RequestResponse} from 'simple-boot-http-server/models/RequestResponse';
import {ReqHeader} from 'simple-boot-http-server/models/datas/ReqHeader';
import {RouterModule} from 'simple-boot-core/route/RouterModule';

@Sim() @Router({path: ''})
export class AppRouter {
    @Route({path: '/'}) @GET({res: {contentType: Mimes.ApplicationJson}})
    index(rr: RequestResponse, header: ReqHeader, routerModule: RouterModule) {
        return {name: 'visualkhh'}
    }
}

const httpServerOption = new HttpServerOption({
    listen: {
        listeningListener: (server, httpServer) => {
            console.log('server on', httpServer.address());
        }
    }
});

const app = new SimpleBootHttpServer(AppRouter, httpServerOption);
app.run();

// 💥 GET /
// {"name": "visualkhh"}

npx ts-node index.ts

curl -XGET http://localhost:8081

METHOD MAPPING

• @GET
• @POST
• @PATCH
• @OPTIONS
• @HEAD
• @TRACE
• @CONNECT
• OTHER
  • @UrlMapping

Method Decorator options

export type MappingConfig = {
    method: HttpMethod | string,
    description?: {
        name?: string;
        detail?: string;
    };

    req?: {
        contentType?: (Mimes|string)[];
        accept?: (Mimes|string)[];
    };

    res?: {
        status?: number;
        header?: {[key: string]: string};
        contentType?: Mimes | string;
    }
    resolver?: Resolver|ConstructorType<Resolver>;
}

Filter

return

• true: after call chain
• false: after NoCall chain

export class FirstFilter implements Filter {
    async before(rr: RequestResponse, app: SimpleBootHttpServer): Promise<boolean> {
        console.log('filter before')
        return true;
    }
    
    async after(rr: RequestResponse, app: SimpleBootHttpServer, sw: boolean): Promise<boolean> {
        console.log('filter after')
        return true;
    }    
}
const httpServerOption = new HttpServerOption({
    filters: [new FirstFilter()],
    listen: {
        listeningListener: (server, httpServer) => {
            console.log('server on', httpServer.address());
        }
    }
});

const app = new SimpleBootHttpServer(AppRouter, httpServerOption);
app.run();
// 💥 CALL
// filter before
// filter after

Advice(ExceptionHandler)

import {NotFoundError} from './NotFoundError';

@Sim
export class Advice {
    @ExceptionHandler({type: NotFoundError})
    catch(rr: RequestResponse, e: any) {
        rr.resSetHeaders({error: 'NotFound'});
        console.log('exception--->', rr.reqUrl, e);
    }
}

const httpServerOption = new HttpServerOption({
    globalAdvice: Advice,
    noSuchRouteEndPointMappingThrow: rr => new NotFoundError(),
    listen: {
        listeningListener: (server, httpServer) => {
            console.log('server on', httpServer.address());
        }
    }
});

const app = new SimpleBootHttpServer(AppRouter, httpServerOption);
app.run();
// 💥 CALL
// exception---> NotFound

EndPoint

@Sim
class CloseEndPoint implements EndPoint {
    async endPoint(rr: RequestResponse, app: SimpleBootHttpServer) {
        console.log('close request response')
    }
}
@Sim
class ErrorEndPoint implements EndPoint {
    async endPoint(rr: RequestResponse, app: SimpleBootHttpServer) {
        console.log('error')
    }
}
const httpServerOption = new HttpServerOption({
    errorEndPoints: [CloseEndPoint],
    closeEndPoints: [ErrorEndPoint],
    listen: {
        listeningListener: (server, httpServer) => {
            console.log('server on', httpServer.address());
        }
    }
});

const app = new SimpleBootHttpServer(AppRouter, httpServerOption);
app.run();
// 💥 normal CALL
// close request response
// 💥 error
// error
