OASGraph CLI

Command line interface (CLI) for turning APIs described by OpenAPI Specification (OAS) into GraphQL interfaces.

Note: To use OASGraph as a library, refer to the oasgraph package.

Installation

npm i -g oasgraph-cli

Usage

Usage: oasgraph <OAS JSON file path or remote url> [options]

Options:
  -V, --version             output the version number
  -p, --port <port>         select the port where the server will start
  -s, --strict              throw an error if OASGraph cannot run without compensating for errors or missing data in the OAS
  -a, --addSubOperations    nest operations based on path hierarchy
  -f, --fillEmptyResponses  create placeholder schemas for operations with HTTP status code 204 (no response) rather than ignore them
  --no-viewer               do not create GraphQL viewer objects for passing authentication credentials
  --save <file path>        save schema to path and do not start server
  -h, --help                output usage information

The basic usage of the CLI takes the specified OAS, creates a GraphQL interface for it, and starts a server to host the GraphQL interface.

oasgraph oas.json

---

You can specify the OAS by pointing to either a local file or a remote url such as http://127.0.0.1:3000/openapi.json. Additionally, you can specify a port number so you can have multiple GraphQL servers running on the same machine.

oasgraph http://127.0.0.1:3000/openapi.json -p 3001

---

OASgraph can also save a GraphQL schema to a local file, which you can use to inspect or change its content. Please note that the following command will not start the GraphQL server.

oasgraph oas.json --save schema.graphql

Please note that the CLI tool is mainly used for quick testing and does not offer all the features that createGraphQlSchema(oas, options) does.
