**What**
This PR introduces experimental Hot Module Replacement (HMR) for the Medusa backend, enabling developers to see code changes reflected immediately without restarting the server. This significantly improves the development experience by reducing iteration time.
### Key Features
- Hot reload support for:
- API Routes
- Workflows & Steps
- Scheduled Jobs
- Event Subscribers
- Modules
- IPC-based architecture: The dev server runs in a child process, communicating with the parent watcher via IPC. When HMR fails, the child process is killed and restarted, ensuring
clean resource cleanup.
- Recovery mechanism: Automatically recovers from broken module states without manual intervention.
- Graceful fallback: When HMR cannot handle a change (e.g., medusa-config.ts, .env), the server restarts completely.
### Architecture

end

```
### How to enable it
Backend HMR is behind a feature flag. Enable it by setting:
```ts
// medusa-config.ts
module.exports = defineConfig({
featureFlags: {
backend_hmr: true
}
})
```
or
```bash
export MEDUSA_FF_BACKEND_HMR=true
```
or
```
// .env
MEDUSA_FF_BACKEND_HMR=true
```

**What**
- This pr mainly lay the foundation the caching layer. It comes with a modules (built in memory cache) and a redis provider.
- Apply caching to few touch point to test

What:
- Added query planning to the Remote Joiner, enabling phased and parallel execution of data aggregation.
- Replaced object deletes with non-enumerable property hiding to improve performance.
** What
- Allow auto-loaded Medusa files to export a config object.
- Currently supports isDisabled to control loading.
- new instance `FeatureFlag` exported by `@medusajs/framework/utils`
- `feature-flags` is now a supported folder for medusa projects, modules, providers and plugins. They will be loaded and added to `FeatureFlag`
** Why
- Enables conditional loading of routes, migrations, jobs, subscribers, workflows, and other files based on feature flags.
```ts
// /src/feature-flags
import { FlagSettings } from "@medusajs/framework/feature-flags"
const CustomFeatureFlag: FlagSettings = {
key: "custom_feature",
default_val: false,
env_key: "FF_MY_CUSTOM_FEATURE",
description: "Enable xyz",
}
export default CustomFeatureFlag
```
```ts
// /src/modules/my-custom-module/migration/Migration20250822135845.ts
import { FeatureFlag } from "@medusajs/framework/utils"
export class Migration20250822135845 extends Migration {
override async up(){ }
override async down(){ }
}
defineFileConfig({
isDisabled: () => !FeatureFlag.isFeatureEnabled("custom_feature")
})
```
* feat: add view_configurations feature flag
- Add feature flag provider and hooks to admin dashboard
- Add backend API endpoint for feature flags
- Create view_configurations feature flag (disabled by default)
- Update order list table to use legacy version when flag is disabled
- Can be enabled with MEDUSA_FF_VIEW_CONFIGURATIONS=true env var
* fix: naming
* fix: feature flags unauthenticated
* fix: add test
* feat: add settings module
* fix: deps
* fix: cleanup
* fix: add more tetsts
* fix: rm changelog
* fix: deps
* fix: add settings module to default modules list
* fix: pr comments
* fix: deps,build
* fix: alias
* fix: tests
* fix: update snapshots
**What**
- Add missing index for query that falls in select in strategy, specifically the heaviest one with variant IN filtering
- Allow to force the strategy to be sent to the entry point module when using the graph API. It is useful with big dataset where filtering is enough without pagination and select in can offer better performances
e.g
```ts
await query.graph({
entity: 'product',
fields,
filters,
strategy: 'select-in' // <-- this will force the module to use receive this value and apply it accordingly
})
```
