Yaak Postman Export Plugin

This plugin exports Yaak requests and collections to Postman Collection v2.1 JSON format.

Features

• Collection/Folder Export: Right-click a workspace or folder and export the entire collection with:
  • Nested folder hierarchy preserved
  • All requests with headers, body, and descriptions
  • Authentication (basic, bearer, API key) with variable conversion
  • Template variable syntax converted from Yaak format (${[varName]}) to Postman format ({{varName}})
  • Proper Postman v2.1.0 collection format

Usage

From Yaak UI (when plugin is installed):

Right-click a workspace or folder and choose "Export Collection to Postman", then:

• Specify the output file path where the Postman collection JSON should be saved
• The collection is exported with all descendants (folders and requests)

CLI (Development)

Install dev dependencies and run the converter:

npm install
npx ts-node src/cli.ts path/to/yaak-export.json out.postman.json

Tests

npm test

How It Works

The plugin uses the Yaak plugin context APIs to:

• List all requests and folders in a workspace
• Automatically detect folder hierarchy
• Detect authentication type from available fields (username → basic, token → bearer, key/value → apikey)
• Convert Yaak template variables to Postman format throughout URLs, bodies, headers, and auth values
• Generate valid Postman v2.1.0 JSON

Notes

• Auth is automatically detected: if username+password present → basic auth, if token present → bearer auth, if key+value → API key auth
• Variables in all contexts (URLs, bodies, headers, auth) are converted from ${[name]} to {{name}}
• Folder hierarchy is preserved using nested item arrays in the Postman format
• Request/folder-level auth overrides collection-level auth (standard Postman behavior)
