title: Environment Types summary: Configure your SilverStripe environment to define how your web application behaves.
Environment Types
SilverStripe knows three different environment types (or "modes"). Each of the modes gives you different tools and behaviors. The environment is managed either through a YML configuration file or in a environment configuration file.
The definition of setting an environment type in a mysite/_config/app.yml
looks like
:::yml
Director:
environment_type: 'dev'
The definition of setting an environment type in a _ss_environment.php
file looks like
:::php
define('SS_ENVIRONMENT_TYPE', 'dev');
The three environment types you can set are dev
, test
and live
.
Dev
When developing your websites, adding page types or installing modules you should run your site in dev
. In this mode
you will see full error back traces and view the development tools without having to be logged in as an administrator
user.
Test Mode
Test mode is designed for staging environments or other private collaboration sites before deploying a site live.
In this mode error messages are hidden from the user and SilverStripe includes [api:BasicAuth] integration if you
want to password protect the site. You can enable that but adding this to your mysite/_config/app.yml
file:
:::yml
---
Only:
environment: 'test'
---
BasicAuth:
entire_site_protected: true
Live Mode
All error messages are suppressed from the user and the application is in it's most secure state.
Checking Environment Type
You can check for the current environment type in config files through the environment
variant.
mysite/_config/app.yml --- Only: environment: 'live' --- MyClass: myvar: live_value --- Only: environment: 'test' --- MyClass: myvar: test_value
Checking for what environment you're running in can also be done in PHP. Your application code may disable or enable certain functionality depending on the environment type.
:::php
if(Director::isLive()) {
// is in live
} else if(Director::isTest()) {
// is in test mode
} else if(Director::isDev()) {
// is in dev mode
}
