PROJECT_NAME

Generated by kool create go-react.

Usage

go run ./

To mount the app under a sub-route, pass --route-prefix:

go run ./ --route-prefix my-app

Then open http://localhost:<port>/my-app/.

Development

Dev Mode

Dev mode starts Vite automatically for frontend hot-reload and proxies requests through the Go backend:

go run ./ --dev

Dev mode also supports route prefixes:

go run ./ --dev --route-prefix my-app

The Go server starts and proxies to a Vite dev server on a free port, so you get instant hot-reload for React changes.

External React Source

The generated frontend includes an external_src/ directory next to src/. Code in that directory can be imported with the @external_src alias:

import { ExternalDemo } from '@external_src/demo-external/frontend/src/ExternalDemo';

The demo route at /external shows this pattern: keep @external_src mapped to the local external_src/ directory, then import through the same relative path you would use inside that directory. For example, a checkout at external_src/agent-traces can expose a React component at:

import { AgentTracesPage } from '@external_src/agent-traces/frontend/src/agent-trace/AgentTracesPage';

You can put as many external React source checkouts, packages, or worktrees as you need under external_src/, such as external_src/admin and external_src/agent-traces, then import them with paths like @external_src/admin/frontend/src/... or @external_src/agent-traces/frontend/src/....

Release Mode (Production Build)

1. Build the frontend:

go run ./script/build-frontend

1. Run the server (embeds the built frontend):

go run ./

Build Binary

go run ./script/build-frontend && go build -o /tmp/__PROJECT_NAME__ ./
