The overlay package provides an API for working with OpenAPI Overlays including applying overlays to specifications, comparing specifications to generate overlays, and validating overlay documents.

CLI Tool

This repository also provides a comprehensive CLI tool for working with OpenAPI specifications, Arazzo workflows, and OpenAPI overlays.

Installation

Install the CLI tool using Go:

go install github.com/speakeasy-api/openapi/cmd/openapi@latest

Usage

The CLI provides three main command groups:

• openapi spec - Commands for working with OpenAPI specifications (documentation)
• openapi arazzo - Commands for working with Arazzo workflow documents (documentation)
• openapi overlay - Commands for working with OpenAPI overlays (documentation)

Quick Examples

# Validate an OpenAPI specification
openapi spec validate ./spec.yaml

# Bundle external references into components section
openapi spec bundle ./spec.yaml ./bundled-spec.yaml

# Inline all references to create a self-contained document
openapi spec inline ./spec.yaml ./inlined-spec.yaml

# Upgrade OpenAPI spec to latest version
openapi spec upgrade ./spec.yaml ./upgraded-spec.yaml

# Apply an overlay to a specification
openapi overlay apply --overlay overlay.yaml --schema spec.yaml

# Validate an Arazzo workflow document
openapi arazzo validate ./workflow.arazzo.yaml

For detailed usage instructions for each command group, see the individual documentation linked above.
