Welcome to 3.0 🎉 This release has it all. New features, bug fixes, breaking changes, performance improvements - something for everyone! The biggest addition to this release is support for the browser via Webpack.

This release has breaking changes. This release has a few breaking changes. These changes are unlikely to affect most clients.

BREAKING: Migration from axios to gaxios

The 2.0 version of this library used the axios library for making HTTP requests. In the 3.0 release, this has been replaced by a mostly API compatible library gaxios. The new request library natively supports proxies, and comes with a smaller dependency chain. While this is mostly an implementation detail, the request method was directly exposed via the GoogleAuth.request and OAuth2Client.request methods. The gaxios library aims to provide an API compatible implementation of axios, but that can never be 100% promised. If you run into bugs or differences that cause issues - please do let us know.

BREAKING: generateCodeVerifier is now generateCodeVerifierAsync

The OAuth2Client.generateCodeVerifier method has been replaced by the OAuth2Client.generateCodeVerifierAsync method. It has changed from a synchronous method to an asynchronous method to support async browser crypto APIs required for Webpack support.

The OAuth2Client.verifySignedJwtWithCerts method has been replaced by the OAuth2Client.verifySignedJwtWithCerts method. It has changed from a synchronous method to an asynchronous method to support async browser crypto APIs required for Webpack support.
