Go Todo App

I am building a small todo app as an opportunity to learn Go. This is a work-in-progress and likely written in unidiomatic Go.

Install locally

After cloning the repo, run the following command to install the Go dependencies locally:

go mod tidy

This project also uses the prettier JavaScript package with the prettier-plugin-go-template plugin to format go templates. Run the following command to install these for template formatting:

npm install

Live reloading of the server during development is accomplished with the air utility. You can install it with the following command:

go install github.com/cosmtrek/air@latest

After installing air, your machine may not have the binary in the PATH. You can create an alias in .bashrc, .zshrc, or other appropriate file where the system's shell settings are loaded:

alias air='$(go env GOPATH)/bin/air'

To begin developing, run the following command:

air

VS Code template support

If you're developing with VS Code and you want better support for .tmpl files, add the following to your settings.json file:

"files.associations": {
  "*.tmpl": "html"
}

Issues

The Go language server has trouble with build tags when developing on Linux. You can see the LSP GitHub issue here.

Todo list

• Wrap in-memory todo store in mutex
• Add flash messages for CRUD actions in middleware
• Add flash messages for CRUD actions in UI
• Add styles
• Embed styles
• Gracefully handle template errors with generic 500
• Generic 404 template, and use same template for missing files
• Replace in-memory todo store with sqlite

If I feel particularly ambitious after completing the items above, I may try the following:

• Add CLI for migrations
• Add authentication
• Segregate user data
