OpenAPI Model Generator CLI

OpenAPI Model Generator CLI is a lightweight command-line interface for generating plain C# models (POCOs) from OpenAPI specifications. It leverages the OpenAPIModelGenerator library to streamline development workflows.

Features

• Generate Models Quickly: Turn OpenAPI schemas into C# models in seconds.
• Custom Output Settings: Specify output directory and namespace for generated files.
• Comprehensive Logs: Monitor each step of the process via the console.
• Platform Agnostic: Works seamlessly on Windows, macOS, and Linux.

Installation

Install the CLI globally using the .NET CLI:

dotnet tool install -g openapi-gen

To update to the latest version:

dotnet tool update -g openapi-gen

Usage

Command Syntax

openapi-gen -i <InputFilePath> -o <OutputDirectory> -n <Namespace>

Options

Examples

Generate Models with Custom Namespace

openapi-gen -i ./openapi.yaml -o ./GeneratedModels -n MyCustomNamespace

Generate Models with Default Namespace

openapi-gen -i ./openapi.json -o ./Models

Display Help

openapi-gen --help

Example Output

Here’s an example of a generated class:

using Newtonsoft.Json;

namespace MyCustomNamespace
{
    public class SampleModel
    {
        [JsonProperty("id")]
        public string Id { get; set; }

        [JsonProperty("name")]
        public string Name { get; set; }
    }
}

Logging

The CLI provides real-time logs to ensure transparency and traceability:

• INFO: Indicates the progress of the operation.
• WARNING: Alerts about potential issues in the input file.
• ERROR: Stops execution for critical errors.

Example Log Output

[INFO] Reading OpenAPI specification from ./openapi.yaml
[INFO] OpenAPI version detected: 3.1.0
[INFO] Generating models in ./GeneratedModels
[INFO] Successfully generated 5 models!

Troubleshooting

Common Issues

1. Invalid Input File Path: Ensure the file path provided via --input exists and is accessible.

2. Permission Issues: Verify you have write permissions for the output directory.

3. Invalid OpenAPI Document: Use an OpenAPI validator to confirm the document adheres to the OpenAPI specification.
