Connect with Go
---------------

This example connects to Redis® service from Go, making use of the ``go-redis/redis`` library.

Variables
'''''''''

These are the placeholders you will need to replace in the code sample:

==================      =============================================================
Variable                Description
==================      =============================================================
``REDIS_URI``           URL for the Redis connection, from the service overview page
==================      =============================================================

Pre-requisites
''''''''''''''

Get the ``go-redis/redis`` library:

.. code::
   
   go get github.com/go-redis/redis/v8

Code
''''
Create a new file named ``main.go``, add the following content and replace the placeholder with the Redis URI:

.. literalinclude:: /code/products/redis/connect.go
   :language: go

This code creates a key named ``key`` with the value ``hello world`` and no expiration time. Then, it gets the key back from Redis and prints its value.

Run the code:

.. code::
   
   go run main.go

If the script runs successfully, the outputs should be:

.. code::
   
   The value of key is: hello world
