When doing go get github.com/talentlessguy/go-web-app it fails to build

go get github.com/talentlessguy/go-web-app
# github.com/talentlessguy/go-web-app
github.com/talentlessguy/go-web-app/main.go:15:5: app.Author undefined (type *cli.App has no field or method Author)

	cli.StringFlag does not implement cli.Flag (Apply method has pointer receiver)

How to fix (optional)

I think it has to do with the new versions of github.com/urfave/cli

Go version

go version go1.15.6 darwin/amd64

Background

Module path is inconsistent with go import path. GO111MODULE=on, run go get github.com/talentlessguy/go-web-app:

go: downloading github.com/talentlessguy/go-web-app v0.0.0-20200622190614-48b1d7b20b5e
go: github.com/talentlessguy/go-web-app upgrade => v0.0.0-20200622190614-48b1d7b20b5e
go get: github.com/talentlessguy/[email protected]: parsing go.mod:
        module declares its path as: create-go-web-app
                but was required as: github.com/talentlessguy/go-web-app 

Solution

Fix the module path:

1. Rename the module path to "github.com/talentlessguy/go-web-app": https://github.com/mikezss/skl-go/blob/master/go.mod#L1

module github.com/talentlessguy/go-web-app
go 1.12
require (
	…
) 

2. Warning the users not to use the module, get "github.com/talentlessguy/go-web-app" in GOPATH mode.

The bug

For now, index.html's script initiates WebSockets on ws://localhost:8080/reload but in theory it must be able to use any port. I guess it can be achieved with html/template, something like {{ .Port }}

Problem

Due to some issues in TinyGo I can't only use it because it lacks syscall/js support for all the DOM. So we need both standard compiler and tinygo as options.

Solution

Add flags to gwa build

gwa build --native

Regular compiler will be used when native flag is passed. Also might use upx for compressing binaries.
