cloudflare-workers/_templates/cloudflare/cron-tinygo

cron-tinygo

• A template for starting a Cloudflare Worker project with a cron job using Go.
• This template uses the workers package to schedule and run cron jobs.

Notice

• A free plan Cloudflare Workers only accepts ~1MB sized workers.
  • TinyGo Wasm binaries probably won't exceed this limit, so you might not need to use a paid plan of Cloudflare Workers.
  • There's also a Go version of this that can be found here.

Usage

• main.go includes a simple cron job implementation. Feel free to edit this code and implement your own cron job logic.

Requirements

• Node.js
• wrangler
  • Just run npm install -g wrangler
• tinygo 0.34.0 or later

Getting Started

• If not already installed, please install the gonew command.

go install golang.org/x/tools/cmd/gonew@latest

• Create a new project using this template.
  • The second argument passed to gonew is the module path of your new app.

gonew github.com/syumai/workers/_templates/cloudflare/cron-go your.module/my-app # e.g. github.com/syumai/my-app
cd my-app
go mod tidy
make dev # start running dev server

• To change the worker name, please edit the name property in wrangler.toml.

Development

Commands

make dev     # run dev server
make build   # build Go Wasm binary
make deploy  # deploy worker

Testing the Dev Server

• To test the cron job, you can simulate the cron event by sending an HTTP request to the dev server.

curl -X POST http://localhost:8787/cron

• You should see the scheduled time printed in the console.
