+
+<img src="http://skywalking.apache.org/assets/logo.svg" alt="Sky Walking logo" height="90px" align="right" />
+
+**SkyWalking-NodeJS**: The NodeJS Agent for Apache SkyWalking, which provides the native tracing abilities for NodeJS project.
+
+**SkyWalking**: an APM(application performance monitor) system, especially designed for
+microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.
+

+
+
+[](https://github.com/apache/skywalking-nodejs/actions?query=branch%3Amaster+event%3Apush+workflow%3A%22Build%22)
+
+## Set up NodeJS Agent
+
+SkyWalking NodeJS SDK requires SkyWalking 8.0+.
+
+```typescript
+import Agent from 'skywalking';
+
+Agent.start({
+ serviceName: '',
+ serviceInstance: '',
+ collectorAddress: '',
+ authorization: '',
+ maxBufferSize: 1000,
+});
+```
+
+The supported environment variables are as follows:
+
+Environment Variable | Description | Default
+| :--- | :--- | :--- |
+| `SW_AGENT_NAME` | The name of the service | `your-nodejs-service` |
+| `SW_AGENT_INSTANCE` | The name of the service instance | Randomly generated |
+| `SW_AGENT_COLLECTOR_BACKEND_SERVICES` | The backend OAP server address | `127.0.0.1:11800` |
+| `SW_AGENT_AUTHENTICATION` | The authentication token to verify that the agent is trusted by the backend OAP, as for how to configure the backend, refer to [the yaml](https://github.com/apache/skywalking/blob/4f0f39ffccdc9b41049903cc540b8904f7c9728e/oap-server/server-bootstrap/src/main/resources/application.yml#L155-L158). | not set |
+| `SW_AGENT_LOGGING_LEVEL` | The logging level, could be one of `CRITICAL`, `FATAL`, `ERROR`, `WARN`(`WARNING`), `INFO`, `DEBUG` | `INFO` |
+| `SW_AGENT_MAX_BUFFER_SIZE` | The maximum buffer size before sending the segment data to backend | `'1000'` |
+
+## Supported Libraries
+
+There're some built-in plugins that support automatic instrumentation of NodeJS libraries, the complete lists are as follows:
+
+Library | Plugin Name
+| :--- | :--- |
+| built-in `http` module | `sw_http` |
