Breaking changes 🚨

Drop Node.js 18 support

Rslib v0.20 requires Node.js 20.19+ or 22.12+, Node.js 18 is no longer supported.

Rsbuild / Rspack v2

Rslib v0.20 now depends on beta version of @rsbuild/core v2 and @rspack/core v2. If you use custom Rsbuild / Rspack configurations or plugins, you may need to make corresponding adjustments.

See the Rsbuild v2 upgrade guide for all breaking changes.

Deprecate experiments.advancedEsm

experiments.advancedEsm is now deprecated and effectively ignored. Advanced ESM behavior is the default in both bundle and bundleless mode.

What you need to do:

• Remove experiments.advancedEsm from your config
• Verify the output behaviour

Rename type StartServerResult

The exported type StartServerResult has been renamed to StartDevServerResult.

Highlights 💡

New JavaScript API

This release introduces a new, comprehensive JavaScript API for Rslib.

See the API docs for details:

• Rslib core methods
• Rslib instance
• Rslib types

Usage

1. Install Rslib: install the @rslib/core package:

npm add @rslib/core -D

2. Create an Rslib instance: call the createRslib method to create an Rslib instance:

import { createRslib } from '@rslib/core';

const rslib = await createRslib();

3. Call Rslib instance methods: use the rslib.build method which will build production outputs:

await rslib.build();

Advanced ESM Output

In previous versions, Rslib integrated Rspack's EsmLibraryPlugin through an experimental configuration of experiments.advancedEsm, aiming to optimize the quality of ESM outputs. Now, we are pleased to announce that this plugin has been stabilized.

In this release, the EsmLibraryPlugin is enabled by default by setting experiments.advancedEsm to true in bundle mode. Developers can directly obtain ESM output that is high-quality, more friendly to static analysis, and supports code splitting without any additional configuration.

Better Rstest Integration

Rslib now supports seamless integration with Rstest.

By using the official @rstest/adapter-rslib, you can directly reuse your Rslib build configurations (such as resolve.alias and source.define) within Rstest. This enables zero-config testing for Rslib projects, ensuring your test environment perfectly mirrors your build environment while eliminating the overhead of maintaining duplicate configurations.

// rstest.config.ts
import { defineConfig } from '@rstest/core';
import { withRslibConfig } from '@rstest/adapter-rslib';

export default defineConfig({
  extends: withRslibConfig({}),
  // Additional Rstest-specific configurations
  // ...
});
