Validation

Strict configuration validation and case insensitivity

Pixie provides strict validation to ensure configuration correctness and prevent common issues with properties files.

Case Insensitivity

All properties in Pixie are case insensitive, meaning users will not encounter failures due to incorrect capitalization. The following entries are treated as equivalent:

user.name = Alice
User.Name = Alice
USER.NAME = Alice

Strict Property Validation

Pixie enforces strict validation of configuration properties to prevent misconfigurations:

• If a property is specified in the configuration file but does not exist in the corresponding class, Pixie will throw an exception at startup
• This ensures that typos or removed properties do not lead to silent failures

For example, given the following properties file:

app.mode = production
app.timeout = 5000

If the app.timeout property is removed from the Java class but remains in the configuration file, Pixie will fail fast with an error, preventing users from relying on “dead” properties.
