@rsbuild/core 1.5.0-beta.0

v1.5.0-beta.0

on Node.js Yarn

Highlights 💡

Drop support for Node 16

Node.js 16 reached its end-of-life on September 11, 2023. Many other npm packages in the ecosystem have also dropped support for Node 16, including webpack-dev-server, css-loader, sass-loader, and so on, which makes maintaining compatibility increasingly challenging. Therefore, we have decided to drop Node 16 support starting from Rsbuild v1.5 to ensure better compatibility with the modern ecosystem.

⚠️ This is a breaking change for users still running Node.js 16. Users will need to upgrade to Node.js 18.12.0 or later to use Rsbuild v1.5.

For users currently using Node.js 16:

1. Upgrade to Node.js 18.12.0 or later (Node.js 22 LTS is recommended)
2. Update your CI/CD pipelines to use the new Node.js version

Parallel Less Compilation

This release adds support for parallel loader execution to @rsbuild/plugin-less. If your project uses the @rsbuild/plugin-less and contains a large number of Less files, you can enable parallel compilation to improve build performance.

pluginLess({
  parallel: true,
});
