Apple Store

This template uses Edge Config as fast storage to control whether the store is open or closed.

Demo

https://edge-functions-feature-flag-apple-store.vercel.app/

How to Use

You can choose from one of the following two methods to use this repository:

One-Click Deploy

After setting up your environment variables, deploy the example using Vercel:

Clone and Deploy

Execute create-next-app with npm or Yarn to bootstrap the example:

npx create-next-app --example https://github.com/vercel/examples/tree/main/edge-functions/feature-flag-apple-store
# or
yarn create next-app --example https://github.com/vercel/examples/tree/main/edge-functions/feature-flag-apple-store

Set up environment variables

Copy the .env.example file in this directory to .env.local (which will be ignored by Git):

cp .env.example .env.local

This example requires you to set up an Edge Config and store its connection string in the EDGE_CONFIG environment variable. Fill the Edge Config you create with this content:

{ "featureFlagsAppleStore_storeClosed": true }

Next, run Next.js in development mode:

npm install
npm run dev

# or

yarn
yarn dev

Deploy it to the cloud with Vercel (Documentation).

Opening / Closing the Store

You can control whether the store is open or not by changing the value of featureFlagsAppleStore_storeClosed. Use API routes or Vercel's Edge Config UI to update Edge Config.

Note that you need to provide your own TEAM_ID_VERCEL and AUTH_BEARER_TOKEN environment variables in .env.local if you want to open or close the store as shown below.

To open the store go to:

http://localhost:3000/api/store/open

To close the store go to:

http://localhost:3000/api/store/close

Alternatively you can use the Edge Config UI in your Vercel dashboard to update the featureFlagsAppleStore_storeClosed value directly.
