+# ecommerce-netlify-functions
+
+This sample demonstrates using Mongoose to build an eCommerce shopping cart using [Netlify Functions](https://www.netlify.com/products/functions/), which runs on [AWS Lambda](https://mongoosejs.com/docs/lambda.html).
+
+Other tools include:
+
+1. Stripe for payment processing
+2. [Mocha](https://masteringjs.io/mocha) and [Sinon](https://masteringjs.io/sinon) for testing
+
+## Running This Example
+
+1. Make sure you have a MongoDB instance running on `localhost:27017`, or update `mongodbUri` in `.config/development.js` to your MongoDB server's address.
+2. Run `npm install`
+3. Run `npm run seed`
+4. Run `npm start`
+5. Visit `http://localhost:8888/.netlify/functions/getProducts` to list all available products
+6. Run other endpoints using curl or postman
+
+## Testing
+
+Make sure you have a MongoDB instance running on `localhost:27017`, or update `mongodbUri` in `.config/test.js` to your MongoDB server's address.
+Then run `npm test`.
+
+```
+$ npm test
+
+> test
+> env NODE_ENV=test mocha ./test/*.test.js
+
+Using test
+
+
+  Add to Cart
+    ✔ Should create a cart and add a product to the cart
+    ✔ Should find the cart and add to the cart
+    ✔ Should find the cart and increase the quantity of the item(s) in the cart
+
+  Checkout
+    ✔ Should do a successful checkout run
+
+  Get the cart given an id
+    ✔ Should create a cart and then find the cart.
+
+  Products
+    ✔ Should get all products.
+
+  Remove From Cart
+    ✔ Should create a cart and then it should remove the entire item from it.
+    ✔ Should create a cart and then it should reduce the quantity of an item from it.
+
