This module provides automatic instrumentation for [`Hapi`](https://hapi.dev).

For automatic instrumentation see the
[@opentelemetry/node](https://github.com/open-telemetry/opentelemetry-js/tree/main/packages/opentelemetry-node) package.

## Installation

```bash
npm install --save @opentelemetry/hapi-instrumentation
```
### Supported Versions
 - @hapi/hapi `^17.0.0`

## Usage

OpenTelemetry Hapi Instrumentation allows the user to automatically collect trace data and export them to their backend of choice, to give observability to distributed systems.

To load a specific instrumentation (Hapi in this case), specify it in the registerInstrumentations' configuration.

```js
const { NodeTracerProvider } = require('@opentelemetry/node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    {
      plugins: {
        '@hapi/hapi': {
          enabled: true,
          // You may use a package name or absolute path to the file.
          path: '@opentelemetry/hapi-instrumentation',
        }
      },
    },
  ],
  tracerProvider: provider,
});
```

To load all of the [supported instrumentations](https://github.com/open-telemetry/opentelemetry-js#plugins), use below approach. Each instrumentation is only loaded when the module that it patches is loaded; in other words, there is no computational overhead for listing instrumentations for unused modules.
```js
const { NodeTracerProvider } = require('@opentelemetry/node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();
registerInstrumentations({
  tracerProvider: provider,
});

```

See [examples/hapi](https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/examples/hapi) for a short example using Hapi

## Hapi Instrumentation Support
This package provides automatic tracing for hapi server routes and [request lifecycle](https://github.com/hapijs/hapi/blob/main/API.md#request-lifecycle) extensions defined either directly or via a Hapi plugin.
