Documentation

This is a TypeScript library compatible with Node and modern Web Browsers. It's inspired by our official Python SDK. We're currently missing a lot of the functionality found in our Python SDK, basic logging functionality is available:

``typescript
import wandb from '@wandb/sdk'

await wandb.init({config: {test: 1}});
wandb.log({acc: 0.9, loss: 0.1});
wandb.log({acc: 0.91, loss: 0.09});
await wandb.finish();
`

We'll be adding additional features like Tables soon.

Integrations

Traces can be logged from langchain versions >= 0.0.75.

`typescript
import {WandbTracer} from '@wandb/sdk/integrations/langchain';

const wbTracer = await WandbTracer.init({project: 'langchain-test'});
// run your langchain workloads...
chain.call({input: "My prompt"}, wbTracer);
// be sure to call finish on the tracer
await WandbTracer.finish();
