Possible disadvantages of OpenAPI Generator

  • Complexity
    Although powerful, OpenAPI Generator can be complex to configure and use effectively, especially for newcomers unfamiliar with OpenAPI specifications and generation nuances.
  • Generated Code Quality
    While the tool generates a significant amount of code, the quality of the generated code might not always match hand-crafted solutions, potentially requiring manual refinements and adjustments.
  • Heavy Dependency
    Relying on a code generator creates a dependency on the tool, which may complicate upgrades over time, especially if custom templates or configurations are heavily used.
  • Learning Curve
    There is a learning curve associated with understanding the OpenAPI specification and how to effectively use the generator, particularly for complex APIs and integrations.
  • Maintenance Overhead
    Keeping up with new releases and ensuring compatibility with updated OpenAPI standards can introduce additional maintenance overhead for teams using the tool extensively.

  • Stop Advertising in Your Commits
    To be fair I've never used Laravel - but I do have a memory of code generators/scaffolders inserting files that made clear they were responsible for work /* * NOTE: This class is auto generated by OpenAPI Generator (https://openapi-generator.tech). * Do not edit the class manually. */. - Source: Hacker News / 2 months ago
  • From Swagger UI to React: Building qcontroller's Frontend
    For the REST API communication, I leveraged OpenAPI Generator to automatically generate TypeScript client code. This API-first approach eliminates the common frontend-backend synchronization problems and ensures type safety across the entire stack. - Source: dev.to / 7 months ago
  • How and Why to Use Patches
    Patches are also useful if we're making manual modifications to any codebase that is being auto-generated, i.e. If we're using openapi-generator off of an OpenAPI spec to create clients and scaffolded server codebases. We would want to maintain the patch as a way to ensure that subsequent re-generations of the code don't wipe out any manual changes we have to make in-between. - Source: dev.to / about 1 year ago
  • Using OpenAPI to Automate API Integration With Rapyd's Payment Gateway
    Manually writing API clients can be time-consuming and result in errors. This is where the OpenAPI specification and tools like OpenAPI Generator are helpful. - Source: dev.to / over 1 year ago
  • Define, Generate, and Implement: An API-First Approach with OpenAPI Generator and FlightPHP
    With your API defined, use the OpenAPI Generator to generate your code automatically. The PHP Flight generator โ€” documented here โ€” was provided by the author and, although its status is still marked as "experimental", it has been my production workhorse for over a year. - Source: dev.to / over 1 year ago

  • Ask HN: What Are You Working On? (September 2025)
    I'm working on Vedro, a Python testing framework as a pytest alternative without the magic and with clear output. The main idea is that tests should just be Python: plain `assert` statements instead of custom matchers, no fixture magic, and when tests fail you get readable diffs that actually show what went wrong. Tests can be simple functions or structured with steps that self-document in the output.... - Source: Hacker News / 10 months ago
  • Always Up-to-Date API Docs Are Real (And No, Itโ€™s Not AI)
    This isn't a pipe dream. It's exactly what vedro-httpx doesโ€Š-โ€Šan official plugin for the Vedro testing framework that not only makes API testing effortless but also generates OpenAPI specs from your test runs. - Source: dev.to / 12 months ago
  • Code Review Chaos to Control: Taming Test Quality
    Since we used Vedro, an open-source Python framework for scenario-based testing, our rules were largely shaped by its syntax. Below is an example of a typical test scenario:. - Source: dev.to / over 1 year ago
  • vedro-fn: Compact Tests, Clear Results
    One of the greatest strengths of Vedro is its scenario-based approach to testing. By modeling tests as clear-cut user stories, Vedro helps you write behavior-driven tests that reflect real-world usage. However, while scenario classes are fantastic for complex tests (like end-to-end scenarios), they can sometimes feel verbose when writing smaller, more straightforward checks, such as unit tests. - Source: dev.to / over 1 year ago
  • Vedro Hooks
    Vedro offers powerful extensibility through its plugin system, allowing you to create robust, reusable solutions that can be shared across different projects and teams. But what if you're just experimenting with your codebase, prototyping a concept, or adding a small tweak? Writing a full plugin might feel like overkill. Thatโ€™s where vedro-hooks comes in. - Source: dev.to / over 1 year ago
