compute-sdk-go

Experimental Go SDK for building Compute@Edge applications with TinyGo.

Quick Start

The Fastly Developer Hub has a great Quick Start guide for Go.

Alternatively, you can take a look at the Go Starter Kit.

You'll also want to take a look at our Recommended Packages section, as this can help with the sharp edges of the SDK, like JSON support.

Installation

First, install TinyGo by following the TinyGo Quick install guide.

Then, you can install compute-sdk-go in your project by running:

go get github.com/fastly/compute-sdk-go

Examples

Examples can be found in the examples directory.

The Fastly Developer Hub has a collection of common use cases in VCL ported to TinyGo. Which also acts as a great set of introductory examples of using TinyGo on Compute@Edge.

API Reference

The API reference documentation can be found on pkg.go.dev/github.com/fastly/compute-sdk-go.

Logging

Logging can be done using a Fastly Compute@Edge Log Endpoint (example), or by using normal stdout like:

fmt.Printf("request received: %s\n", r.URL.String())

Recommended Packages

TinyGo is still a new project, which has yet to get a version 1.0.0. Therefore, the project is incomplete, but in its current state can still handle a lot of tasks on Compute@Edge. For example, some languages features of Go are still missing, such as Reflection support, which is used for things like parsing JSON using the Go standard library. To help with your adoption of compute-sdk-go, here are some recommended packages to help with some of the current missing language features:

JSON Parsing

• valyala/fastjson
• mailru/easyjson
• buger/jsonparser

Additional context on JSON support in TinyGo can be found here
