My hello world project for Golang.

Install the following dependencies:

• Mux
• Mgo.V2
• Viper
• Goblin, for tests

This project uses MongoDB. You can get a free hosted one at mLab. Get the connection string and database name and put them in example.db.json. Rename it to db.json . The default port the server runs is 3000. You can change it in the config if you wish to.

Then you can start the server by running:

go run main.go
 
// OR
 
go build main.go
./main

The server will be running on localhost listening on the port in the config.

With a GET request to localhost:3000/shorten?url={LONG_URL}, you get the short code as result:

{
  "ShortURL": "https://localhost:3000/5h0r1"
}

Navigating to https://localhost:3000/5h0r1 will redirect back to {LONG_URL}.
