**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.

```
### 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:
- 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")
})
```

**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
})
```

**What**
- Add index engine feature flag
- apply it to the `store/products` end point as well as `admin/products`
- Query builder various fixes
- search capabilities on full data of every entities. The `q` search will be applied to all involved joined table for selection/where clauses

What:
- `query.index` helper. It queries the index module, and aggregate the rest of requested fields/relations if needed like `query.graph`.
Not covered in this PR:
- Hydrate only sub entities returned by the query. Example: 1 out of 5 variants have returned, it should only hydrate the data of the single entity, currently it will merge all the variants of the product.
- Generate types of indexed data
example:
```ts
const query = container.resolve(ContainerRegistrationKeys.QUERY)
await query.index({
entity: "product",
fields: [
"id",
"description",
"status",
"variants.sku",
"variants.barcode",
"variants.material",
"variants.options.value",
"variants.prices.amount",
"variants.prices.currency_code",
"variants.inventory_items.inventory.sku",
"variants.inventory_items.inventory.description",
],
filters: {
"variants.sku": { $like: "%-1" },
"variants.prices.amount": { $gt: 30 },
},
pagination: {
order: {
"variants.prices.amount": "DESC",
},
},
})
```
This query return all products where at least one variant has the title ending in `-1` and at least one price bigger than `30`.
The Index Module only hold the data used to paginate and filter, and the returned object is:
```json
{
"id": "prod_01JKEAM2GJZ14K64R0DHK0JE72",
"title": null,
"variants": [
{
"id": "variant_01JKEAM2HC89GWS95F6GF9C6YA",
"sku": "extra-variant-1",
"prices": [
{
"id": "price_01JKEAM2JADEWWX72F8QDP6QXT",
"amount": 80,
"currency_code": "USD"
}
]
}
]
}
```
All the rest of the fields will be hydrated from their respective modules, and the final result will be:
```json
{
"id": "prod_01JKEAY2RJTF8TW9A23KTGY1GD",
"description": "extra description",
"status": "draft",
"variants": [
{
"sku": "extra-variant-1",
"barcode": null,
"material": null,
"id": "variant_01JKEAY2S945CRZ6X4QZJ7GVBJ",
"options": [
{
"value": "Red"
}
],
"prices": [
{
"amount": 20,
"currency_code": "CAD",
"id": "price_01JKEAY2T2EEYSWZHPGG11B7W7"
},
{
"amount": 80,
"currency_code": "USD",
"id": "price_01JKEAY2T2NJK2E5468RK84CAR"
}
],
"inventory_items": [
{
"variant_id": "variant_01JKEAY2S945CRZ6X4QZJ7GVBJ",
"inventory_item_id": "iitem_01JKEAY2SNY2AWEHPZN0DDXVW6",
"inventory": {

"description": "extra variant 1",
"id": "iitem_01JKEAY2SNY2AWEHPZN0DDXVW6"
}
}

Closes: FRMW-2892, FRMW-2893
**What**
Wired up the building block that we merged previously in order to manage data synchronization. The flow is as follow
- On application start
- Build schema object representation from configuration
- Check configuration changes
- if new entities configured
- Data synchronizer initialize orchestrator and start sync
- for each entity
- acquire lock
- mark existing data as staled
- sync all data by batch
- marked them not staled anymore
- acknowledge each processed batch and renew lock
- update metadata with last synced cursor for entity X
- release lock
- remove all remaining staled data
- if any entities removed from last configuration
- remove the index data and relations

Fixes: FRMW-2858
This PR merge the modules exported by the plugins with the modules defined within the user config. As a result, all modules get loaded without changing the internals of the loader.
However, you cannot disable the module of a plugin by re-adding it to the `modules` array. That is something we should handle separately.
We've added the breaking change label because of the following fix:
We did broke the ability to completely disable modules in the past pr's, in this pr we re add the ability to disable a module and that this modules does not get loaded at all. ([here](6dd164f783))

* modules can have an isolated database connection by providing a database config as part of their options on `medusa-config`
CLOSES: FRMW-2593
Fixes: FRMW-2742
In this PR, we fix the build output of the backend source code, which eliminates a lot of magic between the development and production environments.
Right now, we only compile the source files from the `src` directory and write them within the `dist` directory.
**Here's how the `src` directory with a custom module looks like**
```
src
├── modules
│ └── hello
│ ├── index.ts
```
**Here's the build output**
```
dist
├── modules
│ └── hello
│ ├── index.js
```
Let's imagine a file at the root of your project (maybe the `medusa-config.js` file) that wants to import the `modules/hello/index` file. How can we ensure that the import will work in both the development and production environments?
If we write the import targeting the `src` directory, it will break in production because it should target the `dist` directory.
## Solution
The solution is to compile everything within the project and mimic the file structure in the build output, not just the `src` directory.
**Here's how the fixed output should look like**
```
dist
├── src
│ ├── modules
│ │ └── hello
│ │ ├── index.js
├── medusa-config.js
├── yarn.lock
├── package.json
```
If you notice carefully, we also have `medusa-config.js`, `yarn.lock`, and `package.json` within the `dist` directory. We do so to create a standalone built application, something you can copy/paste to your server and run without relying on the original source code.
- This results in small containers since you are not copying unnecessary files.
- Clear distinction between the development and the production code. If you want to run the production server, then `cd` into the `dist` directory and run it from there.
## Changes in the PR
- Breaking: Remove the `dist` and `build` folders. Instead, write them production artefacts within the `.medusa` directory as `.medusa/admin` and `.medusa/server`.
- Breaking: Change the output of the `.medusa/server` folder to mimic the root project structure.
- Refactor: Remove `Symbol.for("ts-node.register.instance")]` check to find from where to load the source code.
- Refactor: Use `tsc` for creating the production build. This ensures we respect `tsconfig` settings when creating the build and also perform type-checking.
