GraphMan

Quickly scaffold a postman collection for a GraphQL API.

GraphMan CLI generates an complete collection from a GraphQL endpoint, containing one request per query & mutation, with pre filled fields, parameters and variables.

Note: GraphMan is designed for the postman-collection spec 2.1

✨GraphMan is fully compatible with the Insomnia API Client out of the box!✨

Motivation

Visualizing and exploring existing graphql APIs can be quite daunting. Using postman to manage all your apis is pretty standard, however creating and maintaining collections is difficult. GraphMan makes thoses things easy, helping you for:

  • Graph discovery
  • Graph testing
  • Collection updating

Usage

GraphMan uses deno as a javascript / typescript runtime. That allows to run the CLI from the file url. To get started:

  • Install deno
  • Run: deno run https://raw.githubusercontent.com/Escape-Technologies/graphman/main/src/index.ts <graphql endpoint url>
  • Import the generated [...].postman_collection.json file in postman.

However if you want to run the CLI locally, clone the repo and run: deno run src/index.ts [url]

Note that deno will ask for network and file-system permissions as it's runtime is secure by default

Examples

You can try graphman on public graphql APIs, and it is a great way to get started with graphQL:

  • Rick&Morty API: deno run https://raw.githubusercontent.com/Escape-Technologies/graphman/main/src/index.ts https://rickandmortyapi.com/graphql
GraphMan collection for the Rick and morty API
Character query for the Rick and morty API collection
