Managing Config ​

The Nexios framework provides a flexible and dynamic configuration system through its MakeConfig class. This system allows for structured configuration management with support for nested attributes, validation, and immutability.

Basic Usage ​

python
from nexios import NexiosApp
from nexios.config import MakeConfig

config = MakeConfig({
    "port": 8000,
    "debug": True
})

app = NexiosApp(config = config)

You can access the configuration using the config attribute of the NexiosApp instance:

python
from nexios import NexiosApp
from nexios.config import MakeConfig

config = MakeConfig({
    "port": 8000,
    "debug": True
})

app = NexiosApp(config = config)

print(app.config.port)  # Output: 8000
print(app.config.debug)  # Output: True

Accessing Configuration Globally ​

The framework provides global configuration management through:

python
from nexios.config import get_config
from nexios import NexiosApp

app = NexiosApp()
# Access global configuration from startup handler
@app.on_startup
async def startup_handler():
    config = get_config()
    print(config.port)  # Output: 8000
# Get global configuration from handler
@app.get("/config")
async def get_config_handler(req, res):
    config = get_config()
    print(config.port)  # Output: 8000
    print(config.debug)  # Output: True
    ...

💡Tip

You get access to the global configuration through the get_config function from any module in your application.

⚠️ Warning

If you try get_config before it has been set, it will raise an exception.

Set Config Dynamically ​

python
from nexios import NexiosApp
from nexios.config import set_config

config = MakeConfig({
    "port": 8000,
    "debug": True
})

app = NexiosApp()
set_config(config)
