swagger-express-ts

Automatically generate and serve swagger.json v2.0.

Getting started

First, install swagger-express-ts.

npm install swagger-express-ts --save

and init tsconfig.json

The Basics

In the examples below, we use inversify-express-utils. inversify-express-utils is not required to work with swagger-express-ts.

Step 1: configure express

import * as bodyParser from "body-parser";
import * as express from "express";
import "reflect-metadata";
import { Container } from "inversify";
import { interfaces, InversifyExpressServer, TYPE } from "inversify-express-utils";
import { VersionController } from "./version/version.controller";
import * as swagger from "swagger-express-ts";
import { SwaggerDefinitionConstant } from "swagger-express-ts";
const config = require ( "../config.json" );

// set up container
const container = new Container ();

// note that you *must* bind your controllers to Controller
container.bind<interfaces.Controller> ( TYPE.Controller )
    .to( VersionController ).inSingletonScope().whenTargetNamed( VersionController.TARGET_NAME );

// create server
const server = new InversifyExpressServer ( container );

server.setConfig( ( app : any ) => {
    app.use( '/api-docs/swagger' , express.static( 'swagger' ) );
    app.use( '/api-docs/swagger/assets' , express.static( 'node_modules/swagger-ui-dist' ) );
    app.use( bodyParser.json() );
    app.use( swagger.express(
        {
            definition : {
                info : {
                    title : "My api" ,
                    version : "1.0"
                } ,
                externalDocs : {
                    url : "My url"
                }
                // Models can be defined here
            }
        }
    ) );
} );

server.setErrorConfig( ( app : any ) => {
    app.use( ( err : Error , request : express.Request , response : express.Response , next : express.NextFunction ) => {
        console.error( err.stack );
        response.status( 500 ).send( "Something broke!" );
    } );
} );

const app = server.build();

app.listen( config.port );
console.info( "Server is listening on port : " + config.port );

Step 2: Decorate your models

@ApiModel( {
    description : "Version description" ,
    name : "Version"
} )
export class VersionModel {

    @ApiModelProperty( {
        description : "Id of version" ,
        required : true,
        example: ['123456789']
    } )
    id : number;

    @ApiModelProperty( {
        description : "" ,
        required : true
    } )
    name : string;

    @ApiModelProperty( {
        description : "Description of version" ,
        required : true
    } )
    description : string;
}

Step 3: Decorate your controllers

@ApiPath({
    path: "/versions",
    name: "Version",
    security: { basicAuth: [] }
})
@controller("/versions")
@injectable()
export class VersionController implements interfaces.Controller {
    public static TARGET_NAME: string = "VersionController";
    
    private data = [{
            id: "1",
            name: "Version 1",
            description: "Description Version 1",
            version: "1.0.0"
        },
        {
            id: "2",
            name: "Version 2",
            description: "Description Version 2",
            version: "2.0.0"
        }];

    @ApiOperationGet({
        description: "Get versions objects list",
        summary: "Get versions list",
        responses: {
            200: { description: "Success", type: SwaggerDefinitionConstant.Response.Type.ARRAY, model: "Version" }
        },
        security: {
            apiKeyHeader: []
        }
    })
    @httpGet("/")
    public getVersions(request: express.Request, response: express.Response, next: express.NextFunction): void {
        response.json(this.data);
    }

    @ApiOperationPost({
        description: "Post version object",
        summary: "Post new version",
        parameters: {
            body: { description: "New version", required: true, model: "Version" }
        },
        responses: {
            200: { description: "Success" },
            400: { description: "Parameters fail" }
        }
    })
    @httpPost("/")
    public postVersion(request: express.Request, response: express.Response, next: express.NextFunction): void {
        if (!request.body) {
            return response.status(400).end();
        }
        this.data.push(request.body);
        response.json(request.body);
    }

}

Step 4: Test

Start your server and test on url : /api-docs/swagger.json

Extra

Serve swagger-ui in your API

You can serve swagger.json and swagger-ui in your API.

npm install swagger-ui-dist --save

Create index.html in new directory "swagger".
