Medusa v1.10.0 — Release Notes & Engineering Impact

<!--  # Version 1.10.0 This version comes with performance improvements to Products retrieval so you can build a better and snapper experience for your customers. CMS_BREAK --> ### Breaking changes **Performance improvements** To improve performance of Cart and Product retrieval, we've changed the `relationLoadStrategy` in Typeorm from `join` to `query`. This means relations are loaded using separate database queries rather than many joins in a single large query. This change also significantly reduces memory usage, as it will produce a much smaller result. Unfortunately, Typeorm's `query`-strategy does not work well in concert with transactions, which is extensively used across our codebase. The separate queries to fetch relations on entities will run outside of an initiated transaction, because it uses a different query runner. This leads to incorrect results in cases where you request entities previously created in an ongoing transaction. Those changes will not have persisted to the database at the time of querying, and will therefore be "invisible" to other query runners. Instead of compromising on the performance of our API, we decided to fix the issue in Typeorm, which can be found in [this PR](https://github.com/typeorm/typeorm/pull/9990). It is still yet to be merged, so for now, we have published a forked version of Typeorm that includes the fix. This is the breaking change of this release. To make sure your project works as expected, you will need to use our forked version in your project until Typeorm accepts our PR and publishes a new version. In your `package.json`, replace the Typeorm version with the following: ``` "typeorm": "npm:@medusajs/typeorm@next" ``` ### Features **Listing products** In #4010, we've introduced checks in our Product API ensuring that product pricing and availability are only set if they are requested. The impacted endpoints are: ``` GET /store/products GET /store/products/:id GET /admin/products GET /admin/products/:id ``` By default, these properties will be set on the product and product variants, but if you specify the `expand` query param on your request, you might not receive product pricing and availability. To include those, add variants and variant prices to the `expand`. It will look like this: ``` GET /store/products?expand="variants,variants.prices" ``` * feat(admin-ui): Metadata for stock locations by @pKorsholm in https://github.com/medusajs/medusa/pull/3955 * feat(medusa): Create-swap with sales channel by @pKorsholm in https://github.com/medusajs/medusa/pull/3998 ### Bugs **Event Bus** In [v1.9.0](https://github.com/medusajs/medusa/releases/tag/v1.9.0), we changed the events system to only fire an event if it had any subscribers. This spawned a bug around wildcard subscribers that we missed in our testing. Wildcard subscribers are supposed to run on all events and are created like so: ``` eventBusService.subscribe("*", someMethodToHandleEvent) ``` To make up for this mistake, we've rolled back the changes introduced in 1.9.0 and will go back to the drawing board at some point in the future. * fix(medusa): products retrieve uses query strategy for performance by @riqwan in https://github.com/medusajs/medusa/pull/3926 * fix(medusa): Use query relation load strategy on Carts by @olivermrbl in https://github.com/medusajs/medusa/pull/3984 * fix(medusa): Performance improvement for variant availability by @pKorsholm in https://github.com/medusajs/medusa/pull/3921 * fix(medusa): Broken payment session migration by @rajshrimohanks in https://github.com/medusajs/medusa/pull/3098 * fix(admin-ui): allocated badge for orders with statuses cancelled and archived by @pKorsholm in https://github.com/medusajs/medusa/pull/3950 * fix(admin-ui): Navigating to tax settings should not break URL by @kasperkristensen in https://github.com/medusajs/medusa/pull/3989 * fix(admin-ui): Pin react-router-dom by @kasperkristensen in https://github.com/medusajs/medusa/pull/3999 * fix(medusa, types, utils, event-bus-local): Revert retrieveSubscribers by @adrien2p in https://github.com/medusajs/medusa/pull/4002 * fix(medusa): Only set product availability + prices if requested by @olivermrbl in https://github.com/medusajs/medusa/pull/#4010 ### Chores * chore: Bump Typeorm to Medusa fork by @olivermrbl in https://github.com/medusajs/medusa/pull/3981 ### New Contributors * @rajshrimohanks made their first contribution in https://github.com/medusajs/medusa/pull/3098 * @vladimirpekez made their first contribution in https://github.com/medusajs/medusa/pull/3972 * @karti16 made their first contribution in https://github.com/medusajs/medusa/pull/3977 **Full Changelog**: https://github.com/medusajs/medusa/compare/v1.9.0...v1.10.0
