Go

Fume supports the use of Go by itself or with the Gin and Fiber framework

Fiber

When creating a project with Fiber, you can use Fume's Adapter

go mod init github.com/you/yourproject
go get github.com/fumeapp/fiber

package main

import (
    fume "github.com/fumeapp/fiber"
    "github.com/gofiber/fiber/v2"
)

func main() {
    app := fiber.New()
    app.GET("/", func(c *fiber.Ctx) { c.Status(200).JSON(&fiber.Map{"message": "Hello World"}) })
    fume.Start(app, fume.Options{})
}

Here is a working example repository

Fume recommends fiber

Gin

When creating a project with Gin, you can use Fume's Adapter

go mod init github.com/you/yourproject
go get github.com/fumeapp/gin

package main

import (
    fume "github.com/fumeapp/gin"
    "github.com/gin-gonic/gin"
)

func main() {
    routes := gin.New()
    routes.GET("/", func(c *gin.Context) { c.JSON(200, gin.H{"message": "Hello World"}) })
    fume.Start(routes, fume.Options{})
}

Here is a working example repository

Go by itself

When creating a project you have the option to choose Lambda Only which will create a project with a single lambda function and skip the API Gateway and CloudFront creation. Using this methodology you may use the AWS Go Adapter to create your lambda function. This is the most basic way to use Go with Fume.

You can get started this way

go mod init github.com/you/yourproject
go get github.com/aws/aws-lambda-go/lambda

Your main.go file will look like this:

package main


import (
    "fmt"
    "github.com/aws/aws-lambda-go/lambda"
)

func main() {
        lambda.Start(Handler)
}

func Handler() {
    fmt.Println("Hello World")
}

Fume has no way of invoking your function if you do this - it is up to you to invoke your function.

No logs will appear in Fume until your function is invoked at least once
