#k0r.eu
A very performant URL shortener service for individuals and small groups.
The service builds upon the Actix web framework and Sled for data handling. Thanks to Actix and the in-memory database you can expect 100k requests handled per second on consumer hardware (my laptop).
#Quick Start
The database will be automatically initialized with a super user if it is not yet existing. The api key can be found in the programs output, which should look similar to the following example:
$ k0r
Database file k0r.db not found. Will be created!
Added first user with api key 859b397c-a933-461d-a9b1-86dd20084c02
Server is listening on 127.0.0.1:8080
This will create a database file in the current directory. You can also give a path instead:
$ k0r /path/to/database.db
For testing, you can fill the database with test URLs using the application API. There is a helper script and already a file with example URLs inside the db folder:
# assuming you're inside the project directory root and the server is running
./db/insert-via-api.sh 859b397c-a933-461d-a9b1-86dd20084c02 db/test.urls
This inserts a bit under two-hundred URLs fetched from 250kb.club a while ago. The file contains simply one URL per line and the script is not doing any checks and will throw at the API whatever it finds.
#API Usage
Get an URL is straight forward as expected:
$ curl 127.0.0.1:8080/1
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>redirect — k0r link shortener service</title>
<meta http-equiv="refresh" content="2; url=https://example.com" />
</head>
<body>You will be redirected to <a href="https://example.com">an example</a>.</body>
</html>
Inserting a URL is simple as well:
$ payload='{
"url":"https://example.com",
"title":"an example",
"description":"totally examplary url",
"key":"859b397c-a933-461d-a9b1-86dd20084c02"
}'
$ curl -X POST localhost:8080 -H 'Content-Type: application/json' -d $payoad
#Planned features
This software is still pre-alpha state and most of the planned features are not yet implemented. See the todo list for more information about the planned features and current state of implementation.
