go - How to setup Goland (or any other jetbrains product) for WASM development with Golang - Stack Overflow

I’m trying to set up GoLand for Go development, specifically for compiling WebAssembly (WASM) files. I’m running into an issue that I hope someone can help me with.

When I attempt to import the syscall/js package in my Go code, I receive the following error:

build constraints exclude all Go files in 'Ilusr/local/go/src/syscall/js'.

To resolve this, I added the following build constraint at the top of my Go file:

//go:build js && wasm

This change allowed me to bypass the error, but unfortunately, it led to a new problem: I no longer have access to GoLand's documentation and code suggestions. This is a significant setback for my development process as I rely heavily on these features for writing and navigating my code.

Configuring GoLand for WebAssembly (Wasm) projects

Initial project configuration

When you first open or start a WebAssembly project in GoLand, it won'’t understand the “syscall/js” package. That’s easily fixable, by changing the GOOS and GOARCH values in the project settings, as shown in the below screenshots.

The screenshot below shows how to access Settings on a Linux desktop. If you're using macOS, you'll probably need to access them through the standard macOS Preferences option. GoLand Wasm.

Configuring Run/Debug settings

With the initial project settings changed, you'll probably want to configure the Run/Debug settings next.

That will let you recompile the .wasm file by just launching Run (Shift+F10 on Linux).

Finished, your GoLand setup should now be complete.
