swagger-petstore VS graphql-spec

Swagger offers more than just a user-friendly interface for exploring APIs. It also provides multiple generators that can produce code typically written by hand. As an Angular developer, this blog post will focus on the typescript-angular generator.

Failed to create a client for Java. The generator imports Java's types instead of TeamCity's. There are bugs described for the Java client in both the Swagger generator and the OpenAPI generator. Let's see how the generator behaves when building a Kotlin client.

[swagger-codegen](https://github.com/swagger-api/swagger-codegen) generates code from an OpenAPI definition, and it supports Rust code output (client and/or server).

Swagger contains three greats tools to work with the specification: Swagger UI, Swagger Editor and Swagger Codegen. The Swagger UI renders OpenAPI specs as interactive API documentation, Swagger Editor is a browser-based editor where you can write OpenAPI specs and Swagger Codegen generates server stubs and client libraries from an OpenAPI spec like the OpenAPI generator.

We ran into some minor issues (#1201, #1210, #1355, #1356 and #1769) and fixed some stuff we stumbled upon along the way, although it didn't really bother us as well (#1451 and #1769).

I am interested in integrating a swagger-codegen generated Python server with an existing Flask application. swagger-codegen generates a Python implementation based on the Connexion library from a Swagger API specification.

The method takes a query, String, and a completion block, (Result<[String], Error>) -> Void, which is triggered once the request finishes. Its internal implementation doesn't really matter since it could be from an external framework or generated by a code generator from the API specification.

The Java codegen options are here: https://github.com/swagger-api/swagger-codegen/issues/7795 (believe it or not).

Creating TS types/interfaces manually can be tedious. But, if you have JSON responses of your APIs, you can quickly convert those JSON responses to TS interfaces using VS Code extension Paste JSON as Code. Also, if your backend already uses Swagger for API, you can auto-generate all the TS types of your API models using swagger-codegen

GraphQL's first draft release was 8 years ago. [1]

It's first non-draft release was 5 years ago. [2]

It's first release under a community foundation was 2 years ago. [3]

I'm a big believer in GraphQL (in fact, at time of writing I'm #2 contributor to the GraphQL spec itself) so it pains me that a tool I built doesn't always have easy ways to achieve the "versionless schema" design that GraphQL encourages when it comes to making significant breaking changes to your underlying database tables. (Personally, I think you should aim for your database schema itself to be versionless, but this is not always possible.) Of course you can build your PostGraphile schema over views instead of tables, but views have their own problems that I won't go into here…

I created a proposal for Map type but didn’t make it through.

The issue with GraphQL is it tries to appease too many masters.

Similar to jsx. The language isn’t evolving.

The good thing is the spec is (almost) frozen, so there’s many implementations, the bad is it can encompass the flexibility of json schema can do.

You’ve probably figured it out by now, but for others who may be in a similar position; GraphQL is a specification (with various implementations) and you can read up on the spec here: https://spec.graphql.org/

If you're asking whether GraphQL supports anonymous objects that can be arbitrarily nested then no, it doesn't.

* Performance: It's just hard to track down what makes an operation slow. The waterfall nature of resolvers is a big contributor

:::note GraphQL Union is available for Types only, not for Inputs. However, the oneOf directive will bridge the gap in the future.
