Problems with Go, GopherJS and vecty versions

Can I run the Go compiler in the browser?

QUESTION

Problems with Go, GopherJS and vecty versions

Asked 2020-Dec-19 at 10:27

There's three language (Go), compiler (GopherJS) and library (Vecty). The problem is that GopherJS requires Go in version 12.x and Vecty requires Go in version 1.14+. Somebody know how to set everytihng to build Vecty project with GopherJS?

GopherJS has been effectively abandoned, and will not be adding support for Go 1.13 or later. That said, there has been some work to support Go 1.13 and 1.14 in some forks. It remains to be seen how much traction a fork is likely to gain moving forward.

You may have some success using one of the unofficial forks, if you really need this to work.

So in summary, your options are:

Use an unofficial fork of GopherJS which supports Go 1.14 sufficiently for your needs.
Use an old or backported* version of Vecty which works with Go 1.12 and GopherJS
Consider using Go/WASM in place of GopherJS.

*You'll likely have to do this backport yourself.

QUESTION

Can I run the Go compiler in the browser?

Asked 2020-Sep-30 at 19:25

I recently found out that Go compiles down to WebAssembly. Cool!

As per this Go doc, the Go toolchain itself is written in Go.

This made me think, can the Go compiler run in the browser? Can I make a website which given a file path through an upload button (though, without uploading anything), can compile a Go project and return the executable as a "download"?

The end result I'm looking for is an executable file saved to disk, not for the Go code to run in a browser, but I don't need the exact scenario above to be followed as long as that is the final result.

If this is possible, what are the limitations, if any?

Additional resources I have looked at:

EDIT: I have started work on this, based on a similar project. The repo can be found here: https://github.com/TR-SLimey/IBGC

It is possible, but it's hard to do.

You can't access files using WebAssembly. Instead, you need the user to drop a folder inside the webpage and use the File and Directory Entries API to get the files and their contents.

But the real problem is passing the files from JS to WASM and vice-versa. You'll also need to replace in the compiler source code all the calls to the Go standard library that would access files to calls to JS functions. Those function need to access the WASM memory directly. You will need to modify the compiler quite a bit.

To download the binary, you can create a Blob, use URL.createObjectURL() to get an URL to that blob, create an element with .download = true and .href = , and then .click() it.

The performance might be worse than running the Go compiler directly, but other than that it should work just fine.

Vulnerabilities

No vulnerabilities reported

Install gopherjs

GopherJS requires Go 1.17 or newer. If you need an older Go version, you can use an older Gopher release.
GOPHERJS_GOROOT - if set, GopherJS uses this value as the default GOROOT value, instead of using the system GOROOT as the default GOROOT value
GOPHERJS_SKIP_VERSION_CHECK - if set to true, GopherJS will not check Go version in the GOROOT for compatibility with the GopherJS release. This is primarily useful for testing GopherJS against unreleased versions of Go.
The package github.com/gopherjs/gopherjs/js (see documentation) provides functions for interacting with native JavaScript APIs. For example the line.
