elm-go-embed-example

A "Hello, world!" example showing how to use go embed to bundle an Elm frontend as part of a Go binary.

Package embed lets you direct the Go compiler to bundle up files as part of the compiled executable.

It's common to build a web application with frontend assets and a Go backend, using the //go:embed directive to package the whole program up as a single executable. This example illustrates how to do just that, where the frontend assets are an Elm application.

Build and run

Run make and find the standalone executable dist/elm-go-embed-example. See the Makefile for the frontend and backend build commands.

Other examles

The main branch of this repo shows a bare minimum setup to bundle an Elm frontend in a Go binary. Other branches have more involved examples:

• Branch elm-spa bundles a frontend built using elm-spa.
  • Backend handles routes prefixed with /api, while others are handled by the elm-spa client-side router. Try visiting /, /blargh, /echo/blargh, or /api/echo/blargh.
