0.150.0

Reactant v0.150.0

v0.150.0 is a release focused on two major goals:

• aligning the project with the modern React 18 ecosystem
• making tree shaking reliable across the runtime package graph

This release also tightens package boundaries, updates examples and templates, and adds automated bundle-verification coverage for the new tree-shaking behavior.

Highlights

• React 18 is now the primary tested path for examples, templates, and workspace tooling
• runtime packages now publish preserved-module ESM for more reliable tree shaking
• reactant-share no longer acts as an umbrella barrel
• Vite-based tree-shaking verification examples were added for reactant-share and the core runtime packages
• CI now verifies the tree-shaking regression path

Breaking Changes

reactant-share root imports are now share-only

reactant-share no longer re-exports APIs from:

• reactant
• data-transport
• reactant-last-action

If your code previously treated reactant-share as a single umbrella package, you must split those imports by package ownership.

Before:

import {
  ViewModule,
  injectable,
  useConnector,
  action,
  state,
  createSharedApp,
  delegate,
  createTransport,
  LastAction,
} from 'reactant-share';

After:

import {
  ViewModule,
  injectable,
  useConnector,
  action,
  state,
} from 'reactant';
import { createTransport } from 'data-transport';
import { LastAction } from 'reactant-last-action';
import { createSharedApp, delegate } from 'reactant-share';

reactant-share/compat was removed

The temporary compatibility entry is no longer supported.

Before:

import {
  ViewModule,
  injectable,
  useConnector,
  action,
  state,
  delegate,
} from 'reactant-share/compat';

After:

import {
  ViewModule,
  injectable,
  useConnector,
  action,
  state,
} from 'reactant';
import { delegate } from 'reactant-share';

reactant and reactant-router are aligned to react-redux@8

If your application consumes reactant or reactant-router and is pinned to react-redux@7, you must upgrade to react-redux@8.1.3.

Recommended upgrade:

npm install react-redux@^8.1.3

or

yarn add react-redux@^8.1.3

Package entrypoints are stricter

Several runtime packages now expose preserved-module ESM via dist/esm/index.js and declare "sideEffects": false.

In practice this means:

• importing from package roots is the supported path
• hard-coded dist/index.esm.js imports should be removed
• undocumented deep imports should be removed
• reactant-share now enforces an explicit exports surface

Supported:

import { createSharedApp, delegate, useLock } from 'reactant-share';

Not supported:

import { something } from 'reactant-share/createApp';
import { something } from 'reactant-share/dist/index.esm.js';

Edge case: reactant-di side-effect-only usage

reactant-di no longer uses its root entry as a generic reflect-metadata side-effect barrel.

Normal DI usage continues to work, but if your application previously relied on:

import 'reactant-di';

only to initialize metadata globally, switch to:

import 'reflect-metadata';

Notable Improvements

React 18 support in reactant-web

reactant-web now exports:

• createRoot
• hydrateRoot
• compatibility render
• compatibility hydrate

This lets Reactant work correctly with React 18-style mounting while still preserving compatibility helpers.

Tree-shaking-friendly runtime package layout

The following packages now participate in the new ESM publishing model:

• reactant
• reactant-di
• reactant-last-action
• reactant-model
• reactant-module
• reactant-redux
• reactant-router
• reactant-router-dom
• reactant-share
• reactant-ssr
• reactant-storage
• reactant-web

Lighter root exports

Several packages now expose lighter helper entrypoints from their roots:

• reactant-storage now exports getRehydrated
• reactant-router now exports history and location-change helpers
• reactant-last-action now exports its options types from a dedicated lightweight module

reactant-router-dom now owns tree-shake-friendly helpers

generatePath and matchPath are now implemented within reactant-router-dom instead of being directly re-exported from react-router-dom, reducing unnecessary runtime reachability in narrow bundle paths.

Verification

This release adds automated and reproducible tree-shaking verification:

• examples/reactant-share-vite-treeshaking
• examples/runtime-vite-treeshaking
• yarn test:treeshaking

These examples were added specifically to verify that narrow imports such as:

import { useLock } from 'reactant-share';

do not pull unrelated shared-app runtime code into Vite production bundles.

Upgrade Checklist

1. Upgrade dependency baselines, especially react-redux@8.1.3.
2. Split all mixed imports from reactant-share.
3. Remove all reactant-share/compat imports.
4. Remove deep imports and any hard-coded dist/index.esm.js references.
5. If needed, replace side-effect-only reactant-di imports with reflect-metadata.
6. Reinstall dependencies and refresh the lockfile.
7. Run:

yarn test
yarn build
yarn test:treeshaking
