Bumps Jest to latest 30.x The `resolutions` pin that kept jsdom at 22.1.0 is removed, so the test environment now runs the jsdom version that jest-environment-jsdom declares (26.1.0 on Jest 30). The matcher aliases that Jest 30 deleted are replaced with their canonical forms across the test suites: `toBeCalled`, `toBeCalledTimes`, `toBeCalledWith`, and `lastCalledWith` become the corresponding `toHaveBeenCalled*` matchers, and `toThrowError` becomes `toThrow`. The custom `toThrow` matcher override is removed in the PR below this one. Jest 30 activates the `node` export condition for CommonJS requires in every test environment, so in the jsdom-based Flight suites `react-server-dom-webpack/client` now resolves to the Node build (which requires an options argument) instead of the browser build. Those suites now map the client entry to `client.browser` explicitly, matching the existing mocks for the `server` and `static` entries, and the Turbopack Node test uses `jest.requireActual` because `client` and `client.node` now resolve to the same file, which otherwise made the mock factory recurse. For the same reason `react-dom/static` resolves to the lazily-initialized Node entry in source mode, so its version-mismatch test is gated to build mode like the other server-entry tests. The obsolete `prettierPath` override is dropped from the base Jest config because Jest 30 works with Prettier 3 for inline snapshots, which also fixes `yarn test -u` crashing on the repo's Prettier 3-only hermes plugin, and the now unused `prettier-2` alias dependency is removed with it. Snapshot files are regenerated for Jest 30's updated snapshot header and formatting. One test now passes a number instead of a string to `jest.advanceTimersByTime`, which fake-timers v13 no longer coerces. --------- Co-authored-by: Claude Code (kimi-k3[1m]) <noreply@anthropic.com>
react-refresh
This package implements the wiring necessary to integrate Fast Refresh into bundlers. Fast Refresh is a feature that lets you edit React components in a running application without losing their state. It is similar to an old feature known as "hot reloading", but Fast Refresh is more reliable and officially supported by React.
This package is primarily aimed at developers of bundler plugins. If you’re working on one, here is a rough guide for Fast Refresh integration using this package.
