openapi-readme 0.4.0
Generate Markdown from an openapi JSON file.
Requires Python: >=3.9

# OpenAPI Readme Generator  <!-- omit in toc -->

Generates Markdown suitable for a README file from a local `openapi.json` file.

I still plan to add more features to this tool, but it is already useful for
generating basic API documentation in Markdown from an OpenAPI schema.

## Installation

This tool can be installed via `uv`, `poetry` or `pip` depending on your needs:

This tool is usually only needed during development, so it is recommended to
install it as a development dependency.

uv:

```console
uv add --dev openapi-readme
```

Poetry:

```console
poetry add openapi-readme --group dev
```

Or Pip:

```console
pip install openapi-readme
```

This will install the `openapi-readme` command line tool.

## Usage

```console
openapi-readme [OPTIONS]
```

Run this in the same directory as your `openapi.json` file. By default the
Markdown output will be printed to the console, but you can redirect it out to
a file too.

The particular styling of the generated Markdown is currently hardcoded, though
plans are afoot to implement some sort of themeing.

## Options Summary

- `--route-level INTEGER`: Number of heading levels to use.  [default: 4]
- `--inject / --no-inject`: Inject generated output into a README file.
  [default: False]
- `--help`: Show this message and exit.

## Options in Detail

### --route-level

Specify the heading level for each Route in the generated documentation. This
defaults to **4** if not specified, ie:

```Markdown
#### **`GET`** _/user/list_
```

### --inject

Injects the new Markdown directly into a `README.md` file in the current
directory, if it is found.
You need to add the placeholder comment `<!--
openapi-schema -->` to your markdown where you want it to be injected:

```Markdown
This is some preceeding text

### API Schema description
<!-- openapi-schema -->

### Next section
The document continues unaffected after the injection.
```

Existing (previously injected) Schemas will be **replaced** by this new data.

## TODO

Future improvement plans

- Take more info from the `openapi.json` file
