# Writing Benchmarks in JavaScript and TypeScript

There are multiple ways to integrate CodSpeed with your JS/TS codebase:

  The most convenient way to run your Node.js benchmarks
</Card>

<Columns cols={2}>
  <Card title="tinybench" href="/benchmarks/nodejs/tinybench">
    A lightweight benchmarking library with a simple API
  </Card>

  <Card title="benchmark.js" href="/benchmarks/nodejs/benchmarkjs">
    The legacy benchmarking library for JavaScript
  </Card>
</Columns>

We recommend using the `vitest` plugin as it is the easiest to use and has the
most features.

If you are already using `benchmark.js` or `tinybench`, check out their
respective plugins as they require only a small wrapping to work with CodSpeed.

To benchmark a user flow end-to-end, use the Playwright integration:
