Pull Request Overview
This PR addresses a performance regression related to SSG (Static Site Generation) builds when output.asyncChunks = true is enabled. The change refactors the bundler chain configuration to use the new environment API instead of the deprecated target parameter, and explicitly disables async chunks for Node.js SSG builds.
Key Changes:
- Migrated from
targetparameter toenvironmentAPI in bundler chain configuration - Replaced
chain.target('async-node')withchain.output.set('asyncChunks', false)to prevent async chunk generation in SSG builds
