echo

Echo Plugin Example

This is an example go-plugin for scafctl that demonstrates how to create a simple provider.

Note: This is the go-plugin source code. When distributed via the catalog, it becomes a provider artifact stored at <registry>/providers/echo:<version>.

Building

go build -o echo-plugin main.go

Publishing to the Catalog

# Build into local catalog
scafctl build provider . --version 1.0.0

# Push to remote registry
scafctl catalog push echo@1.0.0 --catalog ghcr.io/myorg
# Result: ghcr.io/myorg/providers/echo:1.0.0

Usage

The plugin exposes a single "echo" provider that returns its input, optionally converting it to uppercase.

Input Schema

• message (string, required): The message to echo
• uppercase (boolean, optional): Whether to convert the message to uppercase (default: false)

Output Schema

• echoed (string): The echoed message

Example

providers:
  - name: echo
    provider: echo
    inputs:
      message: "Hello, World!"
      uppercase: true

This will output:

{
  "echoed": "HELLO, WORLD!"
}
