🍕 Develop

Get started without external APIs. Access on localhost:1234.

npm install
npm start

Unsplash API (Optional)

Pretty Snap uses the Unsplash API to get images and Cloudflare Workers to proxy API requests signed with an Unsplash access key.

Both service provide a generous free tier which you can use for development and production.

Setup Unsplash:

1. Create an Unsplash app
2. Copy the Unsplash Access Key value

Note: Requests are limited to 50 per hour until your API key is approved for production

Setup a Cloudflare worker:

1. Create a Cloudflare worker
2. Manually paste cloudflare/worker.js code into the online console
3. Open the worker's settings and add this environment variable:

   Variable Name	Value
   ACCESS_KEY	The Unsplash Access Key value from the previous step

Test the API

1. Open the Cloudflare worker's online console
2. Append /api/search?query=nature to the generated url
3. Run the request
4. A 200 response with Unsplash JSON data should display

Use the API

1. Copy the generated base url of your Cloudflare worker
   • e.g. https://<prefix>.<user>.workers.dev
2. Create a .env file (you can use .env.example as a template)
3. Set the value of URL_API to the worker's url
   • e.g. URL_API=https://<prefix>.<user>.workers.dev
4. Set the value of DEV_USE_API to true or remove it completely
5. Delete the Parcel generated .cache folder
6. Rebuild the app

🌍 Deploy

Pretty Snap is deployed statically and uses the Cloudflare worker as an API.

1. Deploy statically via a provider like Netlify.
2. Set the build command to npm run build and output directory to dist
3. Set the environment variable URL_API to the Cloudflare work base url
   • The DEV_USE_API variable can be ignored

Use the API on the same domain (Optional)

Cloudflare allows workers to run on the same domain even when hosted on an external server.

1. Open the Cloudflare DNS tab and configure DNS as follows:

   Type	Name	Content	TTL	Proxy status
   CNAME	some-domain.com	<subdomain>.netlify.app	Auto	Proxied
   CNAME	www	some-domain.com	Auto	Proxied

2. Open the Cloudflare Workers tab and add the following route

   Route	Worker
   *some-domain.com/api*	<select your worker>

Pretty Snap should still render when visiting some-domain.com but XHR requests to some-domain.com/api will now hit the worker. You now have a server and API running on the same domain but hosted in 2 locations 🤯
