New page

'''Before You Begin'''
{{Phoenix-Installation-Required}}

==What you will do==
* Create a new Phoenix application instance

==Create the App==
Select a directory, open a terminal and type:
<syntaxhighlight>
mix phx.new app
</syntaxhighlight>

This creates a new phoenix application named "app".

The terminal will prompt you to download dependencies, select Y for yes.

When dependency downloading is complete, you have the choice to connect your app to a database using the following command.

<pre>
mix ecto.create
</pre>
If you run the command, Elixir will try to connect to your app to your instance of PostgresSQL and create a new database. Phoenix defaults to naming your database the same name as your app with a suffix of '''_dev''' appended to it.

In other words,if your application name is app, Phoenix will try to create a database named <pre> app_dev </pre>. If you application is named todos then Phoenix defaults to creating a database named <pre> todos_dev </pre>.

Before you run '''mix ecto.create''' you can change the database name Phoenix creates for you. You can also change the credentials that Phoenix uses in attempting to connect to your database.

The file that contains this information is:

<syntaxhighlight>
name-of-app/config/dev.exs
</syntaxhighlight>

The relevant part of the code in '''dev.exs''' is here:

<syntaxhighlight>

config :app, App.Repo,
username: "postgres",
password: "postgres",
hostname: "localhost",
database: "app_dev",
</syntaxhighlight>

The database name in the above code can be changed to anything you want. The username and password fields need to match your PostgresSQL installation. If they don't match, Phoenix won't be able to connect to PostgresSQL and your app will be created without a database.

=== Create the Database ===
Enter the database creation command:

<syntaxhighlight>
mix ecto.create
</syntaxhighlight>

=== Run the Database Migration Command ===

<syntaxhighlight>
mix ecto.migrate
</syntaxhighlight>

If you get an error check your Database credentials.
