# cron-tinygo
|
|
|
|
- A template for starting a Cloudflare Worker project with a cron job using Go.
|
|
- This template uses the [workers](https://github.com/syumai/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](https://github.com/syumai/workers/tree/main/_templates/cloudflare/cron-go).
|
|
|
|
## 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](https://developers.cloudflare.com/workers/wrangler/)
|
|
- Just run `npm install -g wrangler`
|
|
- Go 1.21.0 or later
|
|
|
|
## Getting Started
|
|
|
|
- If not already installed, please install the [gonew](https://pkg.go.dev/golang.org/x/tools/cmd/gonew) command.
|
|
|
|
```console
|
|
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.
|
|
|
|
```console
|
|
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
|
|
|
|
```console
|
|
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.
|
|
|
|
```console
|
|
curl -X POST http://localhost:8787/cron
|
|
```
|
|
|
|
- You should see the scheduled time printed in the console.
