| mlflow-tracing |  | The core tracing functionality and manual instrumentation. |

Installation

``bash
npm install mlflow-tracing
`

Quickstart

Start MLflow Tracking Server. If you have a local Python environment, you can run the following command:

`bash
pip install mlflow
mlflow server --backend-store-uri sqlite:///mlruns.db --port 5000
`

If you don't have Python environment locally, MLflow also supports Docker deployment or managed services. See Self-Hosting Guide for getting started.

Instantiate MLflow SDK in your application:

`typescript
import * as mlflow from 'mlflow-tracing';

mlflow.init({
trackingUri: 'http://localhost:5000',
experimentId: ''
});
`

Create a trace:

`typescript
// Wrap a function with mlflow.trace to generate a span when the function is called.
// MLflow will automatically record the function name, arguments, return value,
// latency, and exception information to the span.
const getWeather = mlflow.trace(
(city: string) => {
return The weather in ${city} is sunny;
},
// Pass options to set span name. See https://mlflow.org/docs/latest/genai/tracing/quickstart
// for the full list of options.
{ name: 'get-weather' }
);
getWeather('San Francisco');

// Alternatively, start and end span manually
const span = mlflow.startSpan({ name: 'my-span' });
span.end();
``
