Confidence is a configuration document format, an API, and a foundation for A/B testing. The configuration format is designed to work with any existing JSON-based configuration, serving values based on object path (`'/a/b/c'` translates to ``a.b.c``). In addition, Confidence defines special $-prefixed keys used to filter values for a given criteria.
### Example
Below is an example configuring a hapi server using a dynamic Confidence configuration.
```js
const Hapi = require('@hapi/hapi');
const Confidence = require('@hapipal/confidence');
const store = new Confidence.Store({
server: {
host: 'localhost',
port: {
$param: 'PORT',
$coerce: 'number',
$default: 3000
},
debug: {
$filter: 'NODE_ENV',
$default: {
log: ['error'],
request: ['error']
},
production: {
request: ['implementation']
}
}
}
});
const config = store.get('/', process.env);
const server = Hapi.server(config);
```
Confidence originated in the [hapijs organization](https://github.com/hapijs), and was adopted by hapi pal in April 2019.
