 1 | # O-Devs CloudFlare cache purger
 2 | 
 3 | This project is run on AWS Lambda and is executed every time a pull request is merged on the [Orlando Devs blog repo](https://github.com/OrlandoDevs/orlandodevs.github.io).
 4 | 
 5 | ## Configuring
 6 | 
 7 | Before running this project you need to create a `config.json` file within the root. Feel free to copy and paste the `sample.config.json` before proceeding. You'll need to fill out every field within `config.json`.
 8 | 
 9 | Below is an example of what your `config.json` file should look like:
10 | 
11 | ```js
12 | // File location: `/config.js`
13 | {
14 |   "cloudflare": {
15 |     "key": "cloudflare-key",
16 |     "email": "cloudflare-email",
17 |     "zone": "cloudflare-zone",
18 |     "endpoint": "cloudflare-endpoint"
19 |   }
20 | }
21 | ```
22 | 
23 | ## Deploying
24 | 
25 | Before deploying this project you will need to:
26 | 
27 | 1. Clone this project
28 | 2. Run `npm install`
29 | 3. Zip project and upload to AWS Lambda
30 | 
31 | Be sure to take the following steps when zipping and uploading the project to AWS Lambda:
32 | 
33 | - Include every file within this project in the zip file, including the `node_modules` directory
34 | - Be sure to have `app.js`, `node_modules`, etc in the **root** of your zip files. DO NOT ZIP the parent directory, as this will make things fail on Amazon (trust me I learned this the hard way).
