HTML to go-app Converter

CLI and web app to convert HTML markup to go-app.dev's syntax.

Installation

CLI

Static binaries are also available on GitHub releases.

You can install them like so:

$ curl -L -o /tmp/html2goapp-cli https://github.com/pojntfx/html2goapp/releases/latest/download/html2goapp-cli.linux-$(uname -m)
$ sudo install /tmp/html2goapp-cli /usr/local/bin

Web App

The frontend is also available on GitHub releases in the form of a static .tar.gz archive; to deploy it, simply upload it to a CDN or copy it to a web server. For most users, this shouldn't be necessary though; thanks to @maxence-charriere's go-app package, html2goapp is a progressive web app. By simply visiting the public deployment once, it will be available for offline use whenever you need it:

Usage

Web App

To convert HTML to go-app's syntax, simply paste the HTML you want to convert into the Source Code input and click on Convert. You may set the component name, go-app package import path and target package using the options.

CLI

You can use the CLI to convert a HTML input file to go-app's syntax like so:

$ html2goapp-cli -component PF4Tabs -src example/index.html -pkg example > example/index.go

If you want to use the WebAssembly version of the CLI, use go_js_wasm_exec:

$ /usr/local/go/misc/wasm/go_js_wasm_exec out/cli/html2goapp-cli.js-wasm.wasm -component PF4Tabs -src example/index.html -pkg example > example/index.go

You can find the example index.html and index.go files in this repository.

Troubleshooting

You get the failed to execute 'compile' on 'webassembly': incorrect response mime type. expected 'application/wasm'. error when trying to launch the web app? Please make sure that you have added the WebAssembly MIME type on your webserver.
Elements are missing in the generated output? Make sure you only have one root HTML element and do not include the html, head or body tags in your input.
