Azure Functions Go Handler

Note that the project is in a very early state and breaking changes are likely to occur.

This library allows you to write simple Go functions targeting Azure Functions runtime without worrying too much about the custom handler logic.

The repo contains the custom handler logic and utilities for creating powerfull serverless Go functions.

For basic usage see examples.

Getting Started

If you don't already have it, install Go.

Start using:

• Get the lib: go get -u github.com/NitorCreations/azure-functions-go-handler
• Use the lib: import "github.com/NitorCreations/azure-functions-go-handler"

Use gofunc CLI to init a new project

• Install gofunc if needed (see Cli Reference)
• Create a new project dir and cd: mkdir go-func-app && cd go-func-app
• Initialize project structure gofunc init

Usage

The library provides common utils to handle invocations by the Function Runtime and leave the function logic implementation to the developers.

CLI Reference

The gofunc Command Line Interface provides utilities to help with Go Function Apps.

Installation

go install github.com/NitorCreations/azure-functions-go-handler/cmd/gofunc@latest

Synopsis

Usage:

    gofunc <command> [parameters]

The commands are

    init             create a new Go Function App in the current directory
    generate [dir]   generate func handler code starting from optional [dir], defaults to current directory
    version          print version info and exit
    help             show this help

Init Command

Creates a new Go Function App in the working directory with an example HttpTrigger that is ready to Go.

gofunc init

Generate Command

Generates custom handler code from the available functions. Parameter dir is optional and defaults to current directory.

gofunc generate [dir]

Functions are detected by folders containing a function.json definition file. It is expected that the entry point function can be found in the same directory, has a package name equal to the directory and is named Handle.

To use a different entry point function set the entryPoint property in functions.json.

To skip the function completely in generation set the excluded property to true in functions.json.
