Creating a key for a new Lumen Micro Framework install

Thursday, September 10th, 2015

Lumen is the smaller but faster brother of the popular Laravel Framework. And faster means less features out of the box.

Starting a new Lumen framework is quite easy, once you have the Lumne installer globally installed. I can recommend that.

Install Lumen installer globally

composer global require "laravel/lumen-installer=~1.0"

Once you have installed a new Lumen framework, you actually have to do a few things extra:

  • copy the example.env to .env
  • generate an app key

With Laravel you can issue the command php artisan key:generate to generate the key, but Lumen doesn’t have that feature. Remember it’s smaller to be faster.

Of course you can do it manually, but let’s create a small shell script to do a few things manually.

A helper-script for a new Lumen install

if [ "$1" != "" ]; then

#setup default directory
cd /home/user/web

lumen new $1

cd $1

cp .env.example .env

key=`php -r "echo md5(uniqid()).\"\n\";"`;

sed -i "s/APP_KEY=SomeRandomKey!!!/APP_KEY=$key/" .env


Save the script as in ~/bin, set the appropriate execute permission and you can install a new Lumen framework, by running: website

It will run all the mentioned steps above automatically:

  1. create a new Lumen install
  2. copy the .env file
  3. generate an application key in the .env file
