Features

• Automated Postman Collection Generation: Automatically generate a Postman collection from your FastAPI app.
• Customizable Output: Specify the output file name, collection name, and host URL.
• Bearer Token Authentication: Supports bearer token authentication for secure API testing.
• Detailed Route Information: Includes request headers, body, parameters, and responses in the generated collection.

Installation

You can install fast-man using pip:

pip install fast-man

Usage

To generate a Postman collection, use the fast-man command-line tool. You need to provide the path to your FastAPI app, and you can optionally specify the output file, collection name, and host URL.

fast-man --app core.main:app --output postman_collection.json --name "test-api" --host "http://test.com:8000/api/v1" --readme "README.md"

Using Command-Line Arguments

• --app: The path to the FastAPI app instance (required).
• --output: The output file name for the Postman collection (default: postman_collection.json).
• --name: The name of the Postman collection (default: API Collection).
• --host: The host URL for the API (default: http://localhost).
• --readme: The path to the README.md file (default: README.md).

Note: If you want a custom documentation to be displayed in the Postman collection other than your project's README.md, you can use the --readme flag.

Using in a Script

You can also use fast-man directly in your Python code. Here is an example:

from fast_man.converter import generate_postman_collection
from fastapi import FastAPI

app = FastAPI()

@app.get("/items/{item_id}")
async def read_item(item_id: int):
    return {"item_id": item_id}

@app.post("/items/")
async def create_item(name: str):
    return {"name": name}

generate_postman_collection(
    app=app,
    output_file='postman_collection.json',
    input_name='My API',
    input_host='http://localhost:8000',
    readme_file='README.md'
)

print("Postman collection generated successfully.")

Example

Here is an example of how to use fast-man.

Given the project structure:

my-project/

You can generate the Postman collection using the following command at root:

export PYTHONPATH=$(pwd)
pip install fastapi pydantic requests numpy==1.26.4
pip install -e /Users/renzof/Documents/GitHub/fast-man
fast-man --app core.main:app --output postman_collection.json --name "test-api" --host "http://test.com:8000/api/v1" --readme "README.md"
