URL Shortener with a Google Spreadsheet 📑

This is a simple web server that can redirect a pre-defined set of URLs in Google Sheets. All you need to do is define a Google Sheets like the following, and deploy a simple app just by clicking around.

shortcut	url
code	https://github.com/ahmetb/
book	https://docs.google.com/forms/d/e/1FAIpQLSefArw8NWiha6YCaoTccGZmo4QvuDYY4s87Y_tjW6h4al_4NQ/viewform

Costs: This can be deployed to Google Cloud Run and run for free thanks to generous free tier (+Google Sheets is free with a Gmail account as well).

This redirector also supports path additions on top of base URLs, for example, with the sheet row:

shortcut	url
gcp	https://github.com/GoogleCloudPlatform

The go.ahmet.dev/gcp/golang-samples will be redirected to https://github.com/GoogleCloudPlatform/golang-samples.

Setup

1. Create a new Google Sheet: https://sheets.new.

2. Add two columns, first column is the "shortcut", the second column is the "url" to redirect the user. (see example)

3. Save the ID of your Sheet from the URL (it’s a random string that looks like 1SMeoyesCaGHRlYdGj9VyqD-qhXtab1jrcgHZ0irvNDs).

4. Click to deploy to Cloud Run, and provide your spreadsheet ID while deploying:

   

5. Go to https://console.cloud.google.com/run, click on sheets-url-shortener service. Find the email address written in the "Service Account" section.

6. Go to your Google Sheets, click "Share" and give this email address "Viewer" access on your sheet.

7. Go to https://console.developers.google.com/apis/api/sheets.googleapis.com/overview and make sure the Google Sheets API is enabled.

8. (Optional) If you want to use a custom domain like go.ahmet.dev, go to https://console.cloud.google.com/run/domains and map the sheets-url-shortener to your custom domain!
