Supported Node.js Versions
Our client libraries follow theNode.js release schedule.Libraries are compatible with all currentactive andmaintenance versions ofNode.js.If you are using an end-of-life version of Node.js, we recommend that you updateas soon as possible to an actively supported LTS version.
Google's client libraries support legacy versions of Node.js runtimes on abest-efforts basis with the following warnings:
- Legacy versions are not tested in continuous integration.
- Some security patches and features cannot be backported.
- Dependencies cannot be kept up-to-date.
Client libraries targeting some end-of-life versions of Node.js are available, andcan be installed through npmdist-tags.The dist-tags follow the naming conventionlegacy-(version).For example,npm install @google-cloud/rcloadenv@legacy-8 installs client librariesfor versions compatible with Node.js 8.
