Getting Started
This quick start guide will help you get a full stack web application running in just a few minutes by leveraging amber’s code generators.
It will take us just 7 steps. Let’s get started!

Let’s get started!
Instructions for OS X using Homebrew or MacPorts and Debian/Ubuntu are below. See full installation instructions here for RedHat & CentOS, ArchLinux & Derivatives, and more complete instructions.
Installing Amber with these package managers also installs Crystal.
- Homebrewbrew tap amberframework/amberbrew install amber
- MacPortssudo port selfupdatesudo port install amber
curl -fsSL https://crystal-lang.org/install.sh | sudo bash
Then install Amber (from source)
NOTE: At the time of this writing, v1.4.1 is the current stable release, but you should use the most recent tag in place of that.
sudo apt-get install libreadline-dev libsqlite3-dev libpq-dev libmysqlclient-dev libssl-dev libyaml-dev libpcre3-dev libevent-dev
git clone https://github.com/amberframework/amber.git
cd amber
git checkout v1.4.1
shards install
make
sudo make install
brew tap amberframework/amber
brew install amber
Above are the steps for building from source, the dependencies are specific to Ubuntu/Debian. See full installation instructions for other Linux Distributions.
Amber works with
postgresql
(default), mysql
, or sqlite
.If you don’t already have one of these installed, please follow the guides provided by each database maintainer:
On OS X any of the databases can be installed with
brew install [database]
Docker users can opt to use a database container to develop with as well. By default, a new Amber application generates a
docker-compose.yml
that can be used for this purpose.With all dependencies successfully installed, we can generate a new application with
amber new
After the code for the new application is generated, we will
cd
into the new directory and execute a shards install
.The shards install command may take a little while - it has to download all shard dependencies.
The default setup will use a postgresql database, use
-d mysql
or -d sqlite
for mysql and sqlite, respectively.amber new pet-tracker
cd pet-tracker
With the skeleton application generated, we can generate our first RESTful resource.
The
amber generate scaffold
command will help us do this.g
is shorthand for generate
amber g scaffold Pet name:string breed:string age:integer
Generating the application and the scaffolded resource provides the configuration and migration files needed to set up the database.
amber db
will help us do this, as you will see you can chain the db
commands together.amber db create migrate
This will create a new database and run the migration to create a
pets
table with the specified columns.We can use
amber watch
to both build the binary application and start the server. Additionally, amber watch
will detect code changes then recompile and restart the application automatically.amber watch
The
watch
commands will keep observing for file changes within the project and recompiling the application.Open any browser and goto http://localhost:3000 You should see a home page load and “Pets” in the nav bar. If you click on the “Pets” link, you should be able to perform all seven RESTful actions for the “pets” resource.
You can use these commands to create new awesome applications :-)
amber new pet-tracker
cd pet-tracker
shards install
amber generate scaffold Pet name:string breed:string age:integer
amber db create migrate
amber watch
