The client versioning follows the Elastic Stack versioning, this means that major, minor, and patch releases are done following a precise schedule that often does not coincide with the [Node.js release](https://nodejs.org/en/about/releases/) times. To avoid support insecure and unsupported versions of Node.js, the client **will drop the support of EOL versions of Node.js between minor releases**. Typically, as soon as a Node.js version goes into EOL, the client will continue to support that version for at least another minor release. Unless you are **always** using a supported version of Node.js, we recommend defining the client dependency in your `package.json` with the `~` instead of `^`. In this way, you will lock the dependency on the minor release and not the major. (for example, `~7.10.0` instead of `^7.10.0`). | Node.js Version | Node.js EOL date | End of support | | --------------- | ---------------- | ------------------- | | `8.x` | December 2019 | `7.11` (early 2021) | | `10.x` | April 2021 | `7.12` (mid 2021) | | `12.x` | April 2022 | `8.2` (early 2022) | | `14.x` | April 2023 | `8.8` (early 2023) | | `16.x` | September 2023 | `8.11` (late 2023) | | `18.x` | April 2025 | `9.1` (mid 2025) | ## API ## Usage ## License This software is licensed under the [Apache 2 license](./LICENSE). --- _Source: https://npm.io/package/@elastic/transport · Machine-readable twin of the npm.io package page.
