Install via Cloudflare Workers using wrangler CLI (Custom install)

The Moesif Cloudflare worker can also be created without using the Cloudflare Dashboard, using the Cloudflare/Wrangler CLI tool. More details on Wrangler on cloudflare site

Using Cloudflare/Wrangler CLI allows for automated install using wrangler publish, as well as view/tail using wrangler tail command

For users of Visual Studio Code / VSCode devcontainer

For users who are familiar with using VSCode IDE / Visual Studio Code and developing inside a container, this project includes .devcontainer with automated wrangler and cloudflared installation.

Manual Setup: Install the Cloudflare Wrangler CLI tool and cloudflared

You will need to install wrangler tool using the links above to publish the worker. Additionally, to view (wrangler tail) log files of a worker running in cloudflare, you will need to install cloudflared

Deploying Moesif Worker using wrangler

  1. Clone this repo
git clone [email protected]:Moesif/moesif-cloudflare
cd moesif-cloudflare

  1. Modify src/index.js: At minimum add the Moesif Application Id "applicationId" See README.md

  2. Modify wrangler.toml:

  • Update fields account_id and zone_id obtained from your cloudflare dashboard
  • Update field routes with routes you would like to use. See README.md
  1. Login to cloudflare using wrangler (as needed)
wrangler login
  1. Deploy to cloudflare. To create new worker and associate routes:
wrangler publish

The worker should be running and logging to moesif

Just visit your link on cloudflare using your web browser https://my-cloudflare-domain/my-path or

curl https://my-cloudflare-domain/my-path

The API calls should show up in Moesif event stream.
