I'm new to node, swagger etc.
I'm working on a node.js app, I added some endpoints and using express-validation package I configured validators for my end points.
I now started using also swagger-autogen to generate swagger doc, but I can't find a way to make swagger use the validators in order to provide more data/limitations of the endpoints' parameters.
Is there a way to achieve something like that?
Thanks

How/where does the swagger json for the swagger ui get generated ?
I thought maybe it was Springfox that was automatically doing it, but if I add a field without using the Jhipster 'entity creation' feature the field does not show up in the swagger docs. So obviously something generates it pre build..
is there any way to auto-generate ServiceStack javascript (no typescript) client based on metadata/Swagger? It would be good to integrate that somehow with webpack.
I am not sure is it possible to do this with swagger-js-codegen (This package generates a nodejs or angularjs class from a swagger specification file).
Actually swagger plugin doesn't share service to access swagger.json to get complete schema (the schema is splited). Is there any workaround to use swagger codegen for javascript?
By accessing http://localhost:12116/resources you can get
{"swaggerVersion":"1.2","apis":[{"path":"/resource/assignroles"},{"path":"/resource/auth"},{"path":"/resource/authenticate"},{"path":"/resource/criteria"},{"path":"/resource/import"},{"path":"/resource/tenders"},{"path":"/resource/unassignroles"}],"apiVersion":"1.0","basePath":"http://localhost:12116","info":{"title":"App"}}
and using http://localhost:12116/resource/import
{"swaggerVersion":"1.2","apiVersion":"1.0","basePath":"http://localhost:12116","resourcePath":"/import","apis":[{"path":"/import/stats","operations":[{"method":"GET","nickname":"BrowseImportStats","parameters":[],"errorResponses":[]}]},{"path":"/import/tenders/changes/apply","operations":[{"method":"GET","nickname":"ApplyChanges","parameters":[],"errorResponses":[]},{"method":"POST","nickname":"ApplyChanges","parameters":[{"paramType":"body","name":"body","required":false,"allowMultiple":false,"type":"ApplyChanges"}],"errorResponses":[]},{"method":"PUT","nickname":"ApplyChanges","parameters":[{"paramType":"body","name":"body","required":false,"allowMultiple":false,"type":"ApplyChanges"}],"errorResponses":[]},{"method":"DELETE","nickname":"ApplyChanges","parameters":[],"errorResponses":[]}]},{"path":"/import/tenders/sync","description":"summary","operations":[{"method":"GET","summary":"summary","nickname":"ImportTenders","parameters":[],"errorResponses":[]}]}],"models":{"ImportTenders":{"id":"ImportTenders","properties":{}},"ApplyChanges":{"id":"ApplyChanges","properties":{}},"BrowseImportStats":{"id":"BrowseImportStats","description":"BrowseImportStats","properties":{}}}}

I was able to generate documentation
C:\git\testapp>java -jar swagger-codegen-cli-2.2.1.jar generate -i http

onal-properties emitJSDoc=false,usePromises=true
Given that you've the OpenAPI/Swagger spec, you can leverage Swagger Codegen to generate not only JS API clients but API clients in other langauges (C#, Ruby, PHP, Python, etc), server stubs (Spring, NodeJS, etc) and API documentation.
Here is a good starting point: https://github.com/swagger-api/swagger-codegen#getting-started
(If you do not want to install anything, you can also generate code online: https://github.com/swagger-api/swagger-codegen#online-generators)
I have a working ordinary Hapi application that I'm planning to migrate to Swagger. I installed swagger-node using the official instructions, and chose Hapi when executing 'swagger project create'. However, I'm now confused because there seem to be several libraries for integrating swagger-node and hapi:
hapi-swagger: the most popular one
hapi-swaggered: somewhat popular
swagger-hapi: unpopular and not that active but used by the official Swagger Node.js library (i.e. swagger-node) as default for Hapi projects
I though swagger-hapi was the "official" approach, until I tried to find information on how do various configurations on Hapi routes (e.g. authorization, scoping, etc.). It seems also that the approaches are fundamentally different, swagger-hapi taking Swagger definition as input and generating the routes automatically, whereas hapi-swagger and hapi-swaggered seem to have similar approach with each other by only generating Swagger API documentation from plain old Hapi route definitions.
Considering the amount of contributors and the number of downloads, hapi-swagger seems to be the way to go, but I'm unsure on how to proceed. Is there an "official" Swagger way to set up Hapi, and if there is, how do I set up authentication (preferably by using hapi-auth-jwt2, or other similar JWT solution) and authorization?
EDIT: I also found swaggerize-hapi, which seems to be maintained by PayPal's open source kraken.js team, which indicates that it might have some kind of corporate backing (always a good thing). swaggerize-hapi seems to be very similar to hapi-swagger, although the latter seems to provide more out-of-the-box functionality (mainly Swagger Editor).
Edit: Point 3. from your question and understanding what swagger-hapi actually does is very important. It does not directly serves the swagger-ui html. It is not intended to, but it is enabling the whole swagger idea (which the other projects in points 1. and 2. are actually a bit reversing). Please see below.
It turns out that when you are using swagger-node and swagger-hapi you do not need all the rest of the packages you mentioned, except for using swagger-ui directly (which is used by all the others anyways - they are wrapping it in their dependencies)
I want to share my understanding so far in this hapi/swagger puzzle, hope that these 8 hours that I spent can help others as well.
Libraries like hapi-swaggered, hapi-swaggered-ui, also hapi-swagger - All of them follow the same approach - that might be described like that:
You document your API while you are defining your routes
They are somewhat sitting aside from the main idea of swagger-node and the boilerplate hello_world project created with swagger-cli, which you mentioned that you use.
While swagger-node and swagger-hapi (NOTE that its different from hapi-swagger) are saying:
You define all your API documentation and routes **in a single centralized place - swagger.yaml**
and then you just focus on writing controller logic. The boilerplate project provided with swagger-cli is already exposing this centralized place swagger.yaml as json thru the /swagger endpoint.
Now, because the swagger-ui project which all the above packages are making use of for showing the UI, is just a bunch of static html - in order to use it, you have two options:
1) to self host this static html from within your app
2) to host it on a separate web app or even load the index.html directly from file system.
In both cases you just need to feed the swagger-ui with your swagger json - which as said above is already exposed by the /swagger endpoint.
The only caveat if you chose option 2) is that you need to enable cors for that end point which happened to be very easy. Just change your default.yaml, to also make use of the cors bagpipe. Please see this thread for how to do this.
As #Kitanotori said above, I also don't see the point of documenting the code programmatically. The idea of just describing everything in one place and making both the code and the documentation engine to understand it, is great.
We have used Inert, Vision, hapi-swagger.
server.ts
import * as Inert from '#hapi/inert';
import * as Vision from '#hapi/vision';
import Swagger from './plugins/swagger';
...
...
// hapi server setup
...
const plugins: any[] = [Inert, Vision, Swagger];
await server.register(plugins);
...
// other setup
./plugins/swagger
import * as HapiSwagger from 'hapi-swagger';
import * as Package from '../../package.json';
const swaggerOptions: HapiSwagger.RegisterOptions = {
info: {
title: 'Some title',
version: Package.version
}
};
export default {
plugin: HapiSwagger,
options: swaggerOptions
};
We are using Inert, Vision and hapi-swagger to build and host swagger documentation.
We load those plugins in exactly this order, do not configure Inert or Vision and only set basic properties like title in the hapi-swagger config.
I am part of a project written in TypeScipt and I am trying to add TypeScript Web Server which will be compatible with Swagger.
What is the most basic strategy to implement it, considering easy maintainability.
For Typescript I have notice that exists 'Typson' library for generating a JSON Model from TypeScript Interface.
For Swagger, I have tried using 'swagger-node-restify' library, since it supports adding JSON models to swagger.
However, I encounter some problems:
Typson doesn't support typeScript syntax of Import -
(import {Server} from "restify")
I tried to implement the 'swagger-node-restify' example (Pet Example), however the RESPONSE of the localhost:8080/api-docs.json GET Request is missing all the SPEC data of the API.
{"apiVersion":"0.1","swaggerVersion":"1.1","basePath":"http://localhost:8080","apis":[{"path":"/api-docs.{format}/pet","description":"none"}]}
I suggest to describe a Swagger compliant API using yaml or json and to generate the server from that.
swagger-server can build APIs on top of express in real time (no source code generation).
There are JavaScript code generators :
Call the swagger-codegen client with -l nodejs-server
swagger-node is a great alternative but seems hard to integrate with TypeScript
Yes, you can easily generate Swagger and OpenAPI documents from your TypeScript types by using tsoa. The readme contains all of the setup information that you would need to start using it. It's compatible with express, hapi, koa, and more (via the ability to add your own template for your preferred server type):
https://github.com/lukeautry/tsoa
The advantages that tsoa has over other libraries is:
it both generates the swagger/OpenAPI document and it also validates the types at runtime
(Full Transparency: I am one of the maintainers of tsoa. But I was first a consumer of tsoa and I find it to be a great product... that's why I asked to help maintain it! :) )
Is there any node.js module which would provide full REST api sequelize?
Which must follow associations, so for example if I have tables testsuites (hasMany testcases) and testcases, than the api will allow me to do: get /api/testsuite/1/testcases and it will do all the magic for me?
I checked sequelize-restful, but does not seems to work this way :(
See below libraries can help you in generating REST API with sequelize

2.https://github.com/sequelize/sequelize-restful
