+# 🌐 Shorten URL
+
+A Deno Cloud Function for shortening URL from the [Bitly API](https://dev.bitly.com/) and [TinyURL API](https://tinyurl.com/app/dev).
+
+_Example input:_
+
+```json
+{
+ "provider": "bitly",
+ "url": "https://google.com/"
+}
+```
+
+```json
+{
+ "provider": "tinyurl",
+ "url": "https://google.com/"
+}
+```
+
+_Example output:_
+
+```json
+{
+ "success": true,
+ "url": "https://bit.ly/3y3HDkC"
+}
+```
+
+```json
+{
+ "success": false,
+ "message": "provider is required"
+}
+```
+
+## 📝 Variables
+
+List of variables used by this cloud function:
+
+**BITLY_TOKEN** - Your Bitly API token.
+**TINYURL_TOKEN** - Your TInyURL API token.
+
+## 🚀 Deployment
+
+1. Clone this repository, and enter this function folder:
+
+```
+$ git clone https://github.com/open-runtimes/examples.git && cd examples
+$ cd deno/generate_short_url
+```
+
+2. Enter this function folder and build the code:
+
+```
+docker run -e INTERNAL_RUNTIME_ENTRYPOINT=src/mod.ts --rm --interactive --tty --volume $PWD:/usr/code openruntimes/deno:v2-1.24 sh /usr/local/src/build.sh
+```
+
+As a result, a `code.tar.gz` file will be generated.
+
+3. Start the Open Runtime:
+
+```
+docker run -p 3000:3000 -e INTERNAL_RUNTIME_ENTRYPOINT=src/mod.ts -e INTERNAL_RUNTIME_KEY=secret-key --rm --interactive --tty --volume $PWD/code.tar.gz:/tmp/code.tar.gz:ro openruntimes/deno:v2-1.24 sh /usr/local/src/start.sh
+```
+
+Your function is now listening on port `3000`, and you can execute it by sending `POST` request with appropriate authorization headers. To learn more about runtime, you can visit Deno runtime [README](https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/deno-1.24).
+
+4. Execute function:
+
+```
+curl http:https://localhost:3000/ -d '{"variables":{"BITLY_TOKEN":"[YOUR_API_KEY]"},"payload": "{\"url\":\"https://appwrite.io/\",\"provider\":\"bitly\"}"}' -H "X-Internal-Challenge: secret-key" -H "Content-Type: application/json"
+```
+
+## 📝 Notes
+
+- This function is designed for use with Appwrite Cloud Functions. You can learn more about it in [Appwrite docs](https://appwrite.io/docs/functions).
+- This example is compatible with Deno 1.21 and 1.24. Other versions may work but are not guarenteed to work as they haven't been tested.
