Features
Failing Fast
- Ensures immediate detection of configuration errors at startup, leading to more reliable and maintainable applications.
Configuration Checking
- Facilitates validation and verification of configuration values, ensuring that they meet the application's requirements.
Independent Configuration Injection
- Allows for flexible and decoupled configuration management by enabling the injection of configurations independently across different modules.
Variable Substitutions
- Follows the nestjs-config's variable substitutions. Use environment variables and default values in configuration files. Reference other variables within the same configuration for dynamic settings.
Profiles
- Supports environment-specific configurations through profiles.
- Utilizes the
NESTJS_PROFILESenvironment variable to determine the active profile(s). - Enables merging configurations from multiple profiles, resolving conflicts based on the specified order.
- Simplifies testing by setting a test profile in
jest.preset.js.
Example jest.preset.js:
process.env.NESTJS_PROFILES = 'test';
module.exports = { testEnvironment: 'node' };
