swagger-express-ts
Automatically generate and serve swagger.json v2.0.
Getting started
First, install swagger-express-ts.
npm install swagger-express-ts --saveThe 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

Configure your server like that.
app.use( '/api-docs/swagger', express.static( 'swagger' ) );
