GoFlare

GoFlare is a self-contained Go tool (library + CLI) for deploying Go WASM projects to Cloudflare Workers and Pages. No Node.js, no Wrangler. Pure Go, direct Cloudflare API. Deploy runs in GitHub Actions — secrets never touch the developer's machine.

When to use

• Cloudflare Pages Functions in Go (recommended) — static site + Go edge function deployed via CF Git Integration
• Standalone Cloudflare Workers in Go (WASM)
• Static Cloudflare Pages (Go WASM frontends)

The project mode is inferred from edge/main.go imports — no MODE variable in .env. See BUILD_PAGES_FUNCTIONS.md.

Project layout — Pages Functions (recommended)

CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID are secrets — they live in GitHub Secrets, never in .env.

CLI

Install the CLI:

go install github.com/tinywasm/goflare/cmd/goflare@latest

• goflare auth --check: Validate CLOUDFLARE_API_TOKEN from environment.
• goflare build: Infer mode from edge/main.go imports and produce artifacts.
• goflare deploy: Direct Upload v2. ⚠️ Designed for CI/CD environments. Now includes automatic Pages project provisioning and robust error reporting.

GitHub Setup

Deployment is designed to run in CI. Register secrets in: GitHub → Settings → Secrets and variables → Actions.

Name	Type	Description
CLOUDFLARE_API_TOKEN	Secret	API Token with Workers and Pages permissions
CLOUDFLARE_ACCOUNT_ID	Secret	Your Cloudflare Account ID
D1_DATABASE_ID	Variable	D1 database ID (optional)

For more details see CI_D1_SECRETS.md.

Edge function — Pages Functions (recommended)

edge/main.go:

//go:build wasm

package main

import (
    "github.com/tinywasm/goflare/pages"   // ← this import sets MODE=pages-functions
    "github.com/your-project/routes"
)

func main() {
    r := pages.NewRouter()
    routes.Register(r)
    pages.Serve(r)
}

⚠️ Critical: NO heavy stdlib in wasm code

Files with //go:build wasm (everything under edge/, routes/, modules/, workers/, pages/pages.go, cloudflare/env_wasm.go) NEVER import fmt, strings, errors, encoding/*, net/http, log, io/ioutil. Use tinywasm/fmt, tinywasm/json, tinywasm/strings, tinywasm/fetch instead.

Stdlib inflates the wasm binary ~80% and exceeds Cloudflare Free's 1 MiB limit. TinyGo also does not fully support net/http in js/wasm.

Verification: grep -rE '^\s*"(fmt|strings|errors|encoding|net/http|log|io/ioutil)"' edge/ routes/ modules/ workers/ pages/pages.go cloudflare/env_wasm.go must return empty.

Library usage

cfg := &goflare.Config{
    ProjectName: "myapp",
    AccountID:   "acc-id",
}
g := goflare.New(cfg)
g.Build()
g.Deploy()
