\u003C\u002Fstrong>\n\u003C\u002Fp>\n\n---\n\n## About this project\n\nThis is the JavaScript version of [OpenTelemetry](https:\u002F\u002Fopentelemetry.io\u002F), a framework for collecting traces, metrics, and logs from applications.\n\n## Quick Start\n\n**Much of OpenTelemetry JS documentation is written assuming the compiled application is run as CommonJS.**\nFor more details on ECMAScript Modules vs CommonJS, refer to [esm-support](https:\u002F\u002Fgithub.com\u002Fopen-telemetry\u002Fopentelemetry-js\u002Fblob\u002Fmain\u002Fdoc\u002Fesm-support.md).\n\nThe following describes how to set up tracing for a basic web application.\nFor more detailed documentation, see the website at \u003Chttps:\u002F\u002Fopentelemetry.io\u002Fdocs\u002Finstrumentation\u002Fjs\u002F>.\n\n### Installation\n\nDependencies with the `latest` tag on NPM should be compatible with each other.\nSee the [version compatibility matrix](#package-version-compatibility) below for more information.\n\n```shell\nnpm install --save @opentelemetry\u002Fapi\nnpm install --save @opentelemetry\u002Fsdk-node\nnpm install --save @opentelemetry\u002Fauto-instrumentations-node\n```\n\n**Note:** `auto-instrumentations-node` is a meta package from [opentelemetry-js-contrib](https:\u002F\u002Fgithub.com\u002Fopen-telemetry\u002Fopentelemetry-js-contrib\u002Ftree\u002Fmain\u002Fpackages\u002Fauto-instrumentations-node) that provides a simple way to initialize multiple Node.js instrumentations.\n\n### Set up Tracing\n\n```js\n\u002F\u002F tracing.js\n\n'use strict'\n\nconst process = require('process');\nconst opentelemetry = require('@opentelemetry\u002Fsdk-node');\nconst { getNodeAutoInstrumentations } = require('@opentelemetry\u002Fauto-instrumentations-node');\nconst { ConsoleSpanExporter } = require('@opentelemetry\u002Fsdk-trace-base');\nconst { resourceFromAttributes } = require('@opentelemetry\u002Fresources');\nconst { ATTR_SERVICE_NAME } = require('@opentelemetry\u002Fsemantic-conventions');\n\n\u002F\u002F configure the SDK to export telemetry data to the console\n\u002F\u002F enable all auto-instrumentations from the meta package\nconst traceExporter = new ConsoleSpanExporter();\nconst sdk = new opentelemetry.NodeSDK({\n  resource: resourceFromAttributes({\n    [ATTR_SERVICE_NAME]: 'my-service',\n  }),\n  traceExporter,\n  instrumentations: [getNodeAutoInstrumentations()]\n});\n\n\u002F\u002F initialize the SDK and register with the OpenTelemetry API\n\u002F\u002F this enables the API to record telemetry\nsdk.start();\n\n\u002F\u002F gracefully shut down the SDK on process exit\nprocess.on('SIGTERM', () => {\n  sdk.shutdown()\n    .then(() => console.log('Tracing terminated'))\n    .catch((error) => console.log('Error terminating tracing', error))\n    .finally(() => process.exit(0));\n});\n```\n\n### Run Your Application\n\n```shell\nnode -r .\u002Ftracing.js app.js\n```\n\nThe above example will emit auto-instrumented telemetry about your Node.js application to the console. For a more in-depth example, see the [Getting Started Guide](https:\u002F\u002Fopentelemetry.io\u002Fdocs\u002Flanguages\u002Fjs\u002Fgetting-started\u002F). For more information about automatic instrumentation see [@opentelemetry\u002Fsdk-trace-node][otel-node], which provides auto-instrumentation for Node.js applications. If the automatic instrumentation does not suit your needs, or you would like to create manual traces, see [@opentelemetry\u002Fsdk-trace-base][otel-tracing]\n\n#### Debugging The Setup\n\nIt's possible that an application instrumented as outlined above may not be behaving in an expected manner.\nFor example, if the application is meant to be sending data to an Open Telemetry collector, that collector\nmay not be receiving any data. Insight into such issues can be gained by enabling a diagnostics logger:\n\n```js\n\u002F\u002F Added as additional configuration to tracing.js\n\nconst {\n  diag,\n  DiagConsoleLogger,\n  DiagLogLevel\n} = require('@opentelemetry\u002Fapi');\ndiag.setLogger(new DiagConsoleLogger(), DiagLogLevel.DEBUG);\n```\n\n## Library Author\n\nIf you are a library author looking to build OpenTelemetry into your library, please see [the documentation][docs]. As a library author, it is important that you only depend on properties and methods published on the public API. If you use any properties or methods from the SDK that are not officially a part of the public API, your library may break if an application owner uses a different SDK implementation.\n\n## Supported Runtimes\n\n| Platform Version    | Supported                                     |\n| ------------------- | --------------------------------------------- |\n| Node.js `v24`       | :heavy_check_mark:                            |\n| Node.js `v22`       | :heavy_check_mark:                            |\n| Node.js `v20`       | :heavy_check_mark:                            |\n| Node.js `v18`       | :heavy_check_mark:                            |\n| Older Node Versions | See [Node Support](#node-support)             |\n| Web Browsers        | See [Browser Support](#browser-support) below |\n\n### Node Support\n\nOnly Node.js Active or Maintenance LTS versions are supported.\nPrevious versions of node *may* work, but they are not tested by OpenTelemetry and they are not guaranteed to work.\n\n### Browser Support\n\n> [!IMPORTANT]\n> Client instrumentation for the browser is **experimental** and mostly **unspecified**. If you are interested in\n> helping out, get in touch with the [Client Instrumentation SIG][client-instrumentation-sig].\n\nRather than define versions of specific browsers \u002F runtimes, OpenTelemetry sets the minimum supported version based on the\nunderlying language features used.\n\nThe current minimum language feature support is set as [ECMAScript 2022](https:\u002F\u002F262.ecma-international.org\u002F13.0\u002F) that are available\nin all modern browsers \u002F runtimes.\n\nThis means that if you are targeting or your end-users are using a browser \u002F runtime that does not support ES2022, you will need\nto transpile the code and provide any necessary polyfills for the missing features to ensure compatibility with your target\nenvironments. Any support issues that arise from using a browser or runtime that does not support ES2022 will be closed as \"won't fix\".\n\nThis minimum support level is subject to change as the project evolves and as the underlying language features evolve.\n\n## TypeScript Support\n\nOpenTelemetry JavaScript is built with TypeScript `v5.0.4`. If you have a TypeScript project (app, library, instrumentation, etc.)\nthat depends on it, we recommend using same or higher version to compile the project.\n\nOpenTelemetry JavaScript will follow DefinitelyType's [support policy for TypeScript](https:\u002F\u002Fgithub.com\u002FDefinitelyTyped\u002FDefinitelyTyped#support-window) which sets a support window of 2 years. Support for TypeScript versions older than 2 years will be dropped in minor releases of OpenTelemetry JavaScript.\n\n## Package Version Compatibility\n\nOpenTelemetry is released as a set of distinct packages in 3 categories: API, stable SDK, and experimental.\nThe API is located at [\u002Fapi](\u002Fapi\u002F), the stable SDK packages are in the [\u002Fpackages](\u002Fpackages\u002F) directory, and the experimental packages are listed in the [\u002Fexperimental\u002Fpackages](\u002Fexperimental\u002Fpackages\u002F) directory.\nThere may also be API packages for experimental signals in the experimental directory.\nAll stable packages are released with the same version, and all experimental packages are released with the same version.\nThe below table describes which versions of each set of packages are expected to work together.\n\n| Stable Packages | Experimental Packages |\n| --------------- | --------------------- |\n| 2.0.x           | 0.200.x               |\n| 1.30.x          |
