Bruno to OpenAPI

Convert Bruno collections to OpenAPI specifications with ease. This library provides a simple way to transform Bruno collection directories into standardized OpenAPI 3.x specifications.

Installation

Install the package using npm:

npm install @gyeonghokim/bruno-to-openapi

Get Started

Once installed, you can use the library to convert your Bruno collections to OpenAPI specifications. Below are examples showing how to export to both JSON and YAML formats.

JSON Export (Async)

import { convertBrunoCollectionToOpenAPI } from '@gyeonghokim/bruno-to-openapi';
import fs from 'fs';

async function convertCollection() {
  // Convert Bruno collection directory to OpenAPI specification
  const result = await convertBrunoCollectionToOpenAPI('./path-to-your-bruno-collection-directory');

  // Save as JSON file
  fs.writeFileSync('openapi-spec.json', JSON.stringify(result.spec, null, 2));
  console.log('OpenAPI specification saved as openapi-spec.json');
}

convertCollection();

YAML Export (Async)

To export as YAML, you can use the js-yaml library along with this package:

npm install js-yaml

import { convertBrunoCollectionToOpenAPI } from '@gyeonghokim/bruno-to-openapi';
import yaml from 'js-yaml';
import fs from 'fs';

async function convertCollection() {
  // Convert Bruno collection directory to OpenAPI specification
  const result = await convertBrunoCollectionToOpenAPI('./path-to-your-bruno-collection-directory');

  // Convert to YAML and save
  const yamlString = yaml.dump(result.spec, { indent: 2 });
  fs.writeFileSync('openapi-spec.yaml', yamlString);
  console.log('OpenAPI specification saved as openapi-spec.yaml');
}

convertCollection();

JSON Export (Sync)

import { convertBrunoCollectionToOpenAPISync } from '@gyeonghokim/bruno-to-openapi';
import fs from 'fs';

function convertCollection() {
  // Convert Bruno collection directory to OpenAPI specification synchronously
  const result = convertBrunoCollectionToOpenAPISync('./path-to-your-bruno-collection-directory');

  // Save as JSON file
  fs.writeFileSync('openapi-spec.json', JSON.stringify(result.spec, null, 2));
  console.log('OpenAPI specification saved as openapi-spec.json');
}

convertCollection();

YAML Export (Sync)

import { convertBrunoCollectionToOpenAPISync } from '@gyeonghokim/bruno-to-openapi';
import yaml from 'js-yaml';
import fs from 'fs';

function convertCollection() {
  // Convert Bruno collection directory to OpenAPI specification synchronously
  const result = convertBrunoCollectionToOpenAPISync('./path-to-your-bruno-collection-directory');

  // Convert to YAML and save
  const yamlString = yaml.dump(result.spec, { indent: 2 });
  fs.writeFileSync('openapi-spec.yaml', yamlString);
  console.log('OpenAPI specification saved as openapi-spec.yaml');
}

convertCollection();

Features

• Converts Bruno collections to OpenAPI 3.x specifications
• Supports all common HTTP methods and parameters
• Handles authentication configurations
• Preserves request/response examples
• Maintains folder structures as tags
• Supports both JSON and YAML output formats
• Provides synchronous and asynchronous conversion options
• Includes collection validation utilities

API Reference

The library exports the following functions:

• convertBrunoCollectionToOpenAPI(collectionPath): Asynchronously takes a Bruno collection directory path and returns a Promise resolving to the conversion result containing the OpenAPI specification.
• convertBrunoCollectionToOpenAPISync(collectionPath): Synchronously takes a Bruno collection directory path and returns the conversion result containing the OpenAPI specification (Note: The full synchronous implementation has limitations and it's recommended to use the async version).
• isValidBrunoCollection(collectionPath): Asynchronously validates if a given path contains a valid Bruno collection and returns a Promise resolving to true if valid.
