🔥 Postflame

Postflame is a powerful CLI tool that automatically generates Postman collections from your Hono applications with Zod schema validation. Transform your API routes into ready-to-use Postman collections in seconds!

✨ Features

• 🚀 Automatic Generation - Converts Hono routes to Postman collections instantly
• 📝 OpenAPI Support - Reads from @hono/zod-openapi endpoints for rich documentation
• 🔄 Fallback Parsing - Works even without OpenAPI by parsing routes directly
• ☁️ Direct Upload - Push collections to Postman workspace via API
• 🎯 Zod Integration - Leverages Zod schemas for request/response examples
• 📦 Multiple Content Types - Supports JSON, form-data, and URL-encoded bodies
• 🏷️ Smart Organization - Groups endpoints by tags into folders

📦 Installation

npm install -g postflame

Or use with npx:

npx postflame <path-to-app.ts>

🚀 Quick Start

Super Simple Usage

Just run postflame in your project directory - it will auto-detect your app file!

# Auto-detect and generate
postflame generate

That's it! Postflame will:

1. 🔍 Find your app file (app.ts, index.ts, or main.ts)
2. 📦 Compile TypeScript automatically
3. 🔥 Generate postman.json
4. ☁️ Auto-upload to Postman if POSTMAN_API_KEY is in your .env

With Auto-Upload to Postman

Create a .env file in your project root:

POSTMAN_API_KEY=your_api_key_here

Then run:

postflame generate

Or force push with the --push flag:

postflame generate --push

Custom Options

# Specify input file
postflame generate --input src/app.ts

# Custom output path
postflame generate --output my-api.json

# Short form
postflame gen -i src/app.ts -o api.json -p

📖 Usage Examples

Example Hono App

import { Hono } from 'hono';
import { zValidator } from '@hono/zod-validator';
import { z } from 'zod';

const app = new Hono();

const ProductSchema = z.object({
  name: z.string(),
  price: z.number(),
  description: z.string().optional(),
});

app.get('/products', (c) => {
  return c.json({ products: [] });
});

app.post('/products', zValidator('json', ProductSchema), (c) => {
  const data = c.req.valid('json');
  return c.json({ success: true, product: data });
});

export { app };

Generate Collection

# Just run postflame - it handles everything!
postflame generate

With OpenAPI (Recommended)

For richer documentation with examples and descriptions:

import { OpenAPIHono } from '@hono/zod-openapi';
import { z } from 'zod';

const app = new OpenAPIHono();

app.openapi(
  {
    method: 'post',
    path: '/products',
    tags: ['Products'],
    request: {
      body: {
        content: {
          'application/json': {
            schema: z.object({
              name: z.string().openapi({ example: 'iPhone 15' }),
              price: z.number().openapi({ example: 999 }),
            }),
          },
        },
      },
    },
    responses: {
      200: {
        description: 'Product created successfully',
      },
    },
  },
  (c) => {
    return c.json({ success: true });
  }
);

// Important: Add the doc endpoint
app.doc('/doc', {
  openapi: '3.0.0',
  info: { title: 'My API', version: '1.0.0' },
});

export { app };

🔧 CLI Commands & Options

Commands

postflame generate    # Generate collection (default)
postflame gen         # Short alias
postflame g           # Even shorter!
postflame run         # Alternative alias
postflame help        # Show help

Options

Option	Short	Description	Default
--input <file>	-i	Path to app file	Auto-detected
--output <file>	-o	Output file path	postman.json
--push	-p	Force upload to Postman	Auto if API key in .env

Auto-Detection

Postflame searches for these files in order:

1. app.ts in root directory
2. index.ts in root directory
3. main.ts in root directory
4. server.ts in root directory
5. src/app.ts
6. src/index.ts
7. src/main.ts
8. src/server.ts

Also checks for .js versions of these files.

🔑 Postman API Key Setup

Recommended: Use .env file

Create a .env file in your project root:

POSTMAN_API_KEY=your_api_key_here

Postflame will automatically read this and upload your collection!

Alternative: Environment Variable

# Linux/Mac
export POSTMAN_API_KEY=your_key_here

# Windows (PowerShell)
$env:POSTMAN_API_KEY="your_key_here"

Get Your API Key

1. Go to Postman API Keys
2. Click "Generate API Key"
3. Copy and add to your .env file

🛠️ Programmatic Usage

You can also use Postflame as a library:

import { generatePostmanCollection, saveCollectionToFile } from 'postflame';
import { app } from './app';

const collection = await generatePostmanCollection(app, 'My API');
saveCollectionToFile(collection, 'output.json');
