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

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

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

const rslib = await createRslib();

1. 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
  // ...
});
