Adapters Overview

Mocktioneer runs on multiple edge platforms through the adapter pattern. Each adapter translates platform-specific request/response formats to the common EdgeZero interface.

Available Adapters

Adapter	Platform	Use Case
Axum	Native Rust	Local development, integration testing
Fastly	Fastly Compute	Production edge deployment
Cloudflare	Cloudflare Workers	Production edge deployment
Spin	Spin / Fermyon	Production edge deployment

Spin requires a Spin 4.1+ runtime; see its configuration notes for the reason and the setup.

How Adapters Work

All adapters share the same core logic from mocktioneer-core. The adapter layer handles:

1. Request translation - Convert platform-specific requests to EdgeZero format
2. Response translation - Convert EdgeZero responses to platform format
3. Runtime initialization - Set up logging, configuration
4. Platform features - Access platform-specific APIs (KV stores, etc.)

Choosing an Adapter

For Development

Use the Axum adapter:

• Fastest compile times (native target)
• Standard Rust debugging
• No platform CLI required

cargo run -p mocktioneer-adapter-axum

For Production

Choose based on your infrastructure:

• Fastly Compute - If you're already using Fastly or need their edge network
• Cloudflare Workers - If you're already using Cloudflare or prefer their platform
• Spin / Fermyon - If you're running Spin; needs a 4.1+ runtime

All three provide:

• Global edge deployment
• Low latency
• Automatic scaling

EdgeZero CLI

The EdgeZero CLI provides a unified interface for all adapters. It's maintained in the EdgeZero repository and isn't vendored here, so install it separately if you want to use it.

# Install (requires access to EdgeZero repo)
cargo install --git https://github.com/IABTechLab/edgezero.git edgezero-cli --features cli

# Serve any adapter
edgezero-cli serve --adapter axum
edgezero-cli serve --adapter fastly
edgezero-cli serve --adapter cloudflare
edgezero-cli serve --adapter spin        # needs a Spin 4.1+ runtime

# Build any adapter
edgezero-cli build --adapter fastly

The CLI reads edgezero.toml for adapter commands and configuration. Fastly deployment with declared stores requires a verified application release; see the Fastly breaking change and deployment prerequisites. Direct build and serve commands are also listed on the adapter pages below.

In-repo mocktioneer-cli

This repository also vendors a thin mocktioneer-cli built on the EdgeZero CLI library — no separate install needed:

# Serve / build without a separate CLI install.
cargo run -p mocktioneer-cli -- serve --adapter cloudflare

# typed config (lives only here — validated against MocktioneerConfig)
cp mocktioneer.toml.example mocktioneer.toml       # gitignored per-env copy
cargo run -p mocktioneer-cli -- config validate --strict
cargo run -p mocktioneer-cli -- config diff --adapter axum
cargo run -p mocktioneer-cli -- config push --adapter axum --yes

serve/build/deploy/auth/provision work from either the external edgezero-cli or mocktioneer-cli; the typed config validate / config diff / config push commands are only in mocktioneer-cli.

Common Configuration

All adapters read from the same edgezero.toml:

• Routes are identical across platforms
• Middleware is applied consistently
• Logging levels are configurable per-adapter

See Configuration for details.
