# typescript-k6 [](https://github.com/int128/typescript-k6/actions/workflows/test.yaml)
Write your [grafana/k6](https://k6.io) test with TypeScript, and run the test in GitHub Actions.
## Getting Started
### Run in GitHub Actions
Create a pull request and then k6 will run.
### Run locally
```console
% k6 run src/http-get.ts

execution: local
script: src/http-get.ts

## Datadog k6 integration
### Prepare
To send the metrics from GitHub Actions to Datadog,
1. Create [an API key of Datadog](https://docs.datadoghq.com/account_management/api-app-keys/).
2. Put the API key to the repository secret `DATADOG_API_KEY` in GitHub Actions.
3. Enable [k6 integration](https://docs.datadoghq.com/integrations/k6/) in Datadog.
### Run
The workflow runs the test and exports the metrics to Datadog via OpenTelemetry.
1. Start the Datadog Agent container.
2. Run k6 with [OpenTelemetry output](https://grafana.com/docs/k6/latest/results-output/real-time/opentelemetry/).
3. Datadog Agent sends the metrics to Datadog.
Here is an example of metrics.
