As of November 1, 2021, the AWS SDK for JavaScript (v2) will cease support for the following deprecated Node.js runtime versions:

  • Node.js 0.10 – End of Life (EOL) on October 31, 2016
  • Node.js 0.12 – EOL on December 31, 2016
  • Node.js 4.x – EOL on April 30, 2018
  • Node.js 6.x – EOL on April 30, 2019
  • Node.js 8.x – EOL on December 31, 2019

We strongly encourage users to upgrade to Node.js 10.x or higher, with a particular recommendation for Node.js 14.x, which was released on April 21, 2020, and entered Long-Term Support (LTS) on October 27, 2020. The modular AWS SDK for JavaScript (v3) is now generally available and supports Node.js 10.x or newer. For developers looking to transition their code to v3, please refer to our Migration Guide or explore our self-guided workshop that demonstrates building a simple note-taking application with v2, including detailed migration steps to v3.

Reasons for Change

With the end-of-life status of Node.js versions below 10.x, we are witnessing a decline in community and SDK dependency support for these outdated versions. To ensure that we provide secure and modern libraries, we are aligned with this migration, and we urge you to do the same to protect your applications and services.

Usage Notification

If you are using the AWS SDK for JavaScript (v2) with Node.js versions below 10.x, you will receive the following warning during npm installation:

$ node --version  
v8.11.3  

$ npm install aws-sdk  

...  
The AWS SDK for JavaScript (v2) will no longer support Node.js v8.11.3 as of November 1, 2021. To continue receiving updates to AWS services and bug fixes, please upgrade to Node.js 10.x or later.

Further details can be found at: https://a.co/cf10B3y.

On November 1, 2021, the CHANGELOG.md for AWS SDK for JavaScript (v2) will explicitly outline the SDK version at which support for these runtime versions will be withdrawn. If you have set engine-strict=true, attempting to install newer versions of AWS SDK for JavaScript (v2) on Node.js versions below 10.x will result in the following error:

$ node --version  
v8.11.3  

$ npm install aws-sdk  
...  
npm ERR! code ENOTSUP  
npm ERR! notsup Unsupported engine for aws-sdk@<version>: wanted: {"node":">=10.0.0"} (current: {"node":"8.11.3","npm":"5.6.0"})

Maintenance Guidelines

To check the maintenance status of Node.js versions, please consult the Node.js Release Schedule. New even-numbered versions (e.g., v12.x, v14.x, v16.x) are introduced in April, while odd-numbered versions (e.g., v13.x, v15.x) are released in October. With each release of an odd-numbered version, the previous even-numbered version transitions to LTS.

For further information regarding AWS SDKs and tools maintenance policies, please review the AWS SDKs and Tools Maintenance Policy. Our commitment is to continue supporting SDK dependencies for a minimum of six months after the community or vendor ceases support for those dependencies.
