Go: embed JS files with bindata - go

Question

This question is a follow up to an earlier question of mine. I've closed the question so I hope its okay that I ask a fresh but related question here. Go: embed static files in binary
How do I serve JS files with go-bindata? Do I pass it into html like this
hi.html
<script>{{.Bindata}}></script>
Doesn't seem to work even though I have no compile or JS errors.

Using https://github.com/elazarl/go-bindata-assetfs
Assuming you have the following structure:
myprojectdirectory
├───api
├───cmd
├───datastores
└───ui
├───css
└───js
Where ui is the directory structure you'd like to wrap up and pack into your app...
Generate a source file
The go-bindata-assetfs tool is pretty simple. It will look at the directories you pass to it and generate a source file with variables that can contain the binary data in those files. So make sure your static files are there, and then run the following command from myprojectdirectory:
go-bindata-assetfs ./ui/...
Now, by default, this will create a source file in the package main. Sometimes, this is ok. In my case, it isn't. You can generate a file with a different package name if you'd like:
go-bindata-assetfs.exe -pkg cmd ./ui/...
Put the source file in the correct location
In this case, the generated file bindata_assetfs.go is created in the myprojectdirectory directory (which is incorrect). In my case, I just manually move the file to the cmd directory.
Update your application code
In my app, I already had some code that served files from a directory:
import (
"net/http"
"github.com/gorilla/mux"
)
// Create a router and setup routes
var Router = mux.NewRouter()
Router.PathPrefix("/ui").Handler(http.StripPrefix("/ui", http.FileServer(http.Dir("./ui"))))
// Start listening
http.ListenAndServe("127.0.0.1:3000", Router)
Make sure something like this works properly, first. Then it's trivial to change the FileServer line to:
Router.PathPrefix("/ui").Handler(http.StripPrefix("/ui", http.FileServer(assetFS())))
Compile the app
Now you have a generated source file with your static assets in them. You can now safely remove the 'ui' subdirectory structure. Compile with
go install ./...
And you should have a binary that serves your static assets properly.

Use https://github.com/elazarl/go-bindata-assetfs
From the readme:
go-bindata-assetfs data/...
In your code setup a route with a file server
http.Handle("/", http.FileServer(assetFS()))
