Overview

Shrink is an URL shortener. I build this project to practice while reading book Let's Go.

Features

• Shorten long URLs into compact, easy-to-share links.
• Track the number of times a shortened URL is accessed.
• Secure HTTPS connections using TLS.

Prerequisites

• Go 1.18 or later
• PostgreSQL

Getting Started

Clone the Repository

git clone git@github.com:pujijayanto/shrink.git
cd shrink

Enable SSL

You need to create a directory called tls in root project directory.

Find your Go standard library directory and call tool called generate_cert.go

If you’re using macOs followed the official install instructions, then generate_cert.go file should be located under /usr/local/go/src/crypto/tls.

Then run

cd tls
go run /usr/local/go/src/crypto/tls/generate_cert.go --rsa-bits=2048 --host=localhost

Start the application

Make sure you already enable SSL!.

Example you want to run the application with

• port 3003
• your database name is shrink_dev
• your postgres user of the database is postgres
• your postgres user password is admin

You can run by running

go run ./cmd/web -addr=":3003" -dsn="postgres://postgres:admin@localhost:5432/shrink_dev?sslmode=disable"

You can adjust the value based on your setup.

You can see help by running

go run ./cmd/web -help

And you can go to https://localhost:3003

Running the test

Prerequisites:

1. prepare database for test
2. change the dns in testutils_test.go
3. clear cache go clean -testcache
4. run the test go test ./...
