Breaking changes 3

  • CommonJS applications can require the package on Node 20.19+, 22.12+, and all of 24.x. On older Node releases, require() throws ERR_REQUIRE_ESM.

    12.0.0release notes

  • The package is published as pure ESM with an exports map. Import from the package root; CommonJS consumers can continue using require on supported Node versions.

    12.0.0release notes

  • Deep imports into build internals are no longer resolvable; import from the package root instead.

  • Adds type overloads for decode when the complete option is used, including a nullable return type.

    12.0.2release notes

  • Fixes ESM imports of jsonwebtoken.
