wasmdev

A simple dev server for developing Go WASM projects.

The goal of this is to provide that rapid development approach commonly seen in JavaScript for frontend Go development.

Getting Started

The simplest use for a Go WASM project is with no arguments:

$ wasmdev

Doing this will:

• Build the current project using the Go compiler with GOOS=js and GOARCH=wasm
• Start a development on port 8080 with a HTML shell that will load the compiled WASM file with the "wasm_exec.js" bootstrap file
• Start a file listener that will rebuild the project when any Go files within the project change.

Usage

A couple of arguments are supported at the moment (more likely to come):

• -o: set the target WASM file. The default is "main.wasm"
• -noserve: do not start the dev server. The file listener will still be used.

Roadmap

This project is still in it's early stages but here are the things I'm thinking of adding down the line:

• Loading external JS and CSS resources in the generated HTML shell.
• Proxying requests to another service, e.g. an API.
• Defining configuration in a build file.
• Adding to or customising the build steps.
• Adding hooks to the build process.
• Maybe adding automatic refreshing to the page.
• Possibly a simple plugin architecture to customise the tool in other ways.

There are also a list of known bugs and limitations:

• Can't configure the port.
• Adding new directories to the project do not get picked up by the file listener.
