Environments

Dumbo runs in one of three environments: development, production or testing.

Setting the environment#

Pass it to the constructor:

$app = new Dumbo('production');

Or set the DUMBO_ENV environment variable:

DUMBO_ENV=production php -S localhost:8000 index.php

When neither is set, Dumbo defaults to development. Constants are available for each one:

$app = new Dumbo(Dumbo::ENV_PRODUCTION);

Reading the environment#

$app->getEnvironment();   // "production"
$app->isDevelopment();    // false

$app->get('/', fn($context) => $context->text($context->get('environment')));

What changes#

In development, uncaught errors render an HTML page with the stack trace. In every other environment they respond with a generic JSON 500. See error handling.
