Shorter

A service web application that helps users shorten long URLs into a shorter URL.
Inspired by IPFS style hashing methods to detect similar files.
Long URLs which have Short URLs (Surls) created will show all existing short URLs for that URL. Users can choose to either create public Surls which can be seen by everyone or opt to login (via Google) to create private URLs that will only be shown to the creating user.

Svelte
Firebase Realtime Database

Setting up Firebase

API_KEY=PUT_YOUR_API_KEY_FROM_FIREBASE_HERE
AUTH_DOMAIN=PUT_YOUR_URL_FROM_FIREBASE_HERE
DATABASE_URL=PUT_YOUR_URL_FROM_FIREBASE_HERE
PROJECT_ID=PUT_YOUR_PROJECT_ID_FROM_FIREBASE_HERE
STORAGE_BUCKET=PUT_YOUR_STORAGE_BUCKET_FROM_FIREBASE_HERE
MESSAGING_SENDER_ID=PUT_YOUR_ID_HERE
APP_ID=PUT_YOUR_ID_HERE
MEASUREMENT_ID=PUT_YOUR_ID_HERE

Svelte

This is a project built on Svelte. Run the following code to install needed dependencies.

npm install

Note that you will need to have Node.js installed.

...then start Rollup:

npm run dev

Navigate to localhost:8080 or refer to CLI for another port number if 8080 is taken.

If you're using Visual Studio Code it is recommend to instal the official extension Svelte for VS Code. If you are using other editors you may need to install a plugin in order to get syntax highlighting and intellisense.

Building and running in production mode

To create an optimised version of the app:

npm run build

Important Note

The current configuration of the source codes are meant for production. Certain changes are needed to run on localhost. Changing the url format from https:// to http:// for two fetch functions are needed. They are the fetch title of website function at Input.svelte and the redirection function at Db.svelte.

Disclaimer

The website's front-end development was coded with the latest browser supports in mind, legacy browsers may not be supported.

Known Bugs

Checking for another Long URL while the <Title> is being fetched for the previous Long URL may result in the previous title replacing the currently displayed <Title> if the previous Long URL fetch takes too long.
