Cloudflare Worker Deployment: Wrangler CLI

Wrangler is Cloudflare's official CLI tool for developing and deploying Workers.

Prerequisites for Wrangler CLI Deployment

Before proceeding with Wrangler CLI deployment, ensure you have the following:

Node.js: Version 22 or later recommended. You can download it from nodejs.org.
npm: Version 9 or later. This usually comes bundled with Node.js.
Git: A local Git client for cloning repositories.
pnpm: This project uses pnpm for package management. If you don't have it, install it globally.

Clone the repository using git:

git clone https://github.com/CutTheCrapTech/email-gateway-cloudflare.git

Install Wrangler (and project dependencies):
```
cd packages/cloudflare-worker
pnpm install
```
Authenticate with Cloudflare:
```
npx wrangler login
```
Follow the prompts in your browser to authenticate your Wrangler CLI with your Cloudflare account.
Build the worker:
```
pnpm run build
```
This command compiles your worker code into a deployable JavaScript file.
Create configuration file:
```
cp wrangler.toml.template wrangler.toml
```
Edit the wrangler.toml file with your specific values for name, main, compatibility_date, EMAIL_OPTIONS, and [[email]] section as described in the Configuration section.
Set secrets:
```
wrangler secret put EMAIL_SECRET_MAPPING
```
When prompted, paste your JSON string for EMAIL_SECRET_MAPPING (e.g., {"secret1": "user1@gmail.com", "secret2": "user2@gmail.com"}).
Deploy:
```
wrangler deploy
```
This command deploys your worker to Cloudflare.
