danielgtaylor/apisprout repository overview

A simple, quick, cross-platform API mock server that returns examples specified in an API description document. Features include:

• OpenAPI 3.x support
  • Uses operation examples or generates examples from schema
• Load from a URL or local file (auto reload with --watch)
• CORS headers enabled by default
• Accept header content negotiation
  • Example: Accept: application/*
• Prefer header to select response to test specific cases
  • Example: Prefer: status=409
• Server validation (enabled with --validate-server)
  • Validates scheme, hostname/port, and base path
  • Supports localhost out of the box
  • Use the --add-server flag, in conjunction with --validate-server, to dynamically include more servers in the validation logic
• Request parameter & body validation (enabled with --validate-request)
• Configuration via:
  • Files (/etc/apisprout/config.json|yaml)
  • Environment (prefixed with SPROUT_, e.g. SPROUT_VALIDATE_SERVER)
  • Commandline flags

Usage is simple:

# Load from a local file
apisprout my-api.yaml

# Validate server name and use base path
apisprout --validate-server my-api.yaml

# Dynamically Include a new server / path in the validation
apisprout --add-server http://localhost:8080/mock --validate-server my-api.yaml

# Load from a URL
apisprout https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/api-with-examples.yaml

⁠Docker Image

A hosted API Sprout Docker image⁠ is provided that makes it easy to deploy mock servers or run locally. For example:

docker pull danielgtaylor/apisprout
docker run -p 8000:8000 danielgtaylor/apisprout http://example.com/my-api.yaml

Configuration can be passed via environment variables, e.g. setting SPROUT_VALIDATE_REQUEST=1, or by passing commandline flags. It is also possible to use a local API description file via Docker Volumes⁠:

# Remember to put the full path to local archive YAML in -v
docker run -p 8000:8000 -v $FULLPATH/localfile.yaml:/api.yaml danielgtaylor/apisprout /api.yaml

⁠Installation

Download the appropriate binary from the releases⁠ page.

Alternatively, you can use go get:

go get github.com/danielgtaylor/apisprout

⁠Extra Features

⁠Remote Reload

If your API spec is loaded from a remote URL, you can live-reload it by hitting the /__reload endpoint.

⁠Health Check

A simple endpoint which returns status code 200 is available at /__health. This endpoint successfully returns 200 even if --validate-server is turned on, and the endpoint is being accessed from a non-validated host.

⁠Contributing

Contributions are very welcome. Please open a tracking issue or pull request and we can work to get things merged in.
