Medusa v1.12.0 — Release Notes & Engineering Impact

<!--  # Version 1.12.0 This version comes with a new Reservation Management section in Medusa Admin to allow merchants to easily get an overview of and manage all existing Reservations. CMS_BREAK --> ### Highlights **Breaking changes** In our quest to improve performance, a public method in the PriceSelectionStrategy has been updated to support bulk calculations of variant prices. Specifically, the following signatures have changed: ```ts // Before calculateVariantPrice(variantId: string, context: PriceSelectionContext): Promise<PriceSelectionResult> ``` ```ts // Now calculateVariantPrice(data: { variantId: string; quantity?: number; }[], context: PriceSelectionContext): Promise<Map<string, PriceSelectionResult>> ``` Additionally (non-breaking), the following DB indexes have been added: ```ts idx_money_amount_variant_id ON money_amount (variant_id); idx_money_amount_region_id ON money_amount (region_id); idx_product_option_value_variant_id ON product_option_value (variant_id); idx_product_option_value_option_id ON product_option_value (option_id); idx_gin_product_title ON product USING gin (title gin_trgm_ops); idx_gin_product_description ON product USING gin (description gin_trgm_ops); idx_gin_product_variant_title ON product_variant USING gin (title gin_trgm_ops); idx_gin_product_variant_sku ON product_variant USING gin (sku gin_trgm_ops); idx_gin_product_collection ON product_collection USING gin (title gin_trgm_ops); ``` The packages `class-validator` and `class-transformer` have been removed from `@medusajs/utils`. The `TransactionBaseService` has been removed from `@medusajs/utils`. This class should be imported from `@medusajs/medusa`. The utilities `build-query`, `db-aware-column`, `base-entity`, and `soft-deletable-entity` have been removed from `@medusajs/utils`. These should be imported from `@medusajs/medusa`. **Support for SQLite dropped** SQLite support was initially added to reduce friction for developers trying Medusa for the first time. It runs on most operating systems without installation, allowing you to start a Medusa starter without preparing a Postgres database. Though, as we've added features that use more advanced database concepts, we've seen that SQLite has started to cause more harm than good. And frankly, we've not prioritized maintaining the support, as removing it was always part of our plans. SQLite still allows developers to get started very quickly. However, as soon as you start using our admin system or set up the storefront starter, issues caused by the limitations of SQLite arise. These issues are primarily centered around transaction management. A concept used extensively in our core and poorly supported by SQLite. Therefore, as of this release, SQLite is no longer supported. The pros simply do not outweigh the cons at this point. _What does this mean for your setup?_ In the highly unlikely case that you are using SQLite, this will be a breaking change. So, you'll need to set up Postgres for your Medusa server as part of bumping to this version. You can find a [guide in our documentation](https://docs.medusajs.com/development/backend/configurations#postgresql-configurations) on how to do this. If you are not using SQLite, these changes will not affect your setup. **Reservation management** With the introduction of our Inventory Module, we added the notion of reservations. Right now, reservations are, from a store administrator perspective, limited to order items and cannot really be used outside the context of an order - unless you consume the API directly. In this release, we ship the first elements to more extensive reservation management, including an overview of all reservations and the ability to search and edit existing reservations. The feature is still WIP, so we will hide the UI behind a new feature flag, `reservations`, that you can [enable as any other feature flag](https://docs.medusajs.com/development/feature-flags/toggle), if you want to start playing around with the feature now. ### Features * feat(medusa): Add location id filtering to list location levels by @pKorsholm in https://github.com/medusajs/medusa/pull/4066 * allow backorder by @pKorsholm in https://github.com/medusajs/medusa/pull/4051 * feat(plugins): Config Modules by @juanzgc in https://github.com/medusajs/medusa/pull/4094 * feat(medusa): Remove sqlite support by @olivermrbl in https://github.com/medusajs/medusa/pull/4026 * feat(medusa): Improve prices flow by @adrien2p in https://github.com/medusajs/medusa/pull/3703 * feat(modules-sdk): Module as singleton instances by @carlos-r-l-rodrigues in https://github.com/medusajs/medusa/pull/4065 * feat(medusa-plugin-contentful): Initial implementation of inventory module by @pKorsholm in https://github.com/medusajs/medusa/pull/3991 * feat(medusa-file-local): Local file storage plugin by @olivermrbl in https://github.com/medusajs/medusa/pull/4118 * feat(medusa): Revert pricing service setVariantPrices API by @adrien2p in https://github.com/medusajs/medusa/pull/4130 * feat(medusa, admin-ui): Update edit allocation modal by @pKorsholm in https://github.com/medusajs/medusa/pull/4071 * feat(admin-ui,medusa): Reservations management by @pKorsholm in https://github.com/medusajs/medusa/pull/4081 * feat(medusa-plugin-mailchimp): Migrate to TS + add update endpoint by @tomekpur in https://github.com/medusajs/medusa/pull/4040 * feat(medusa,inventory,types): Expand list-reservation capabilities by @pKorsholm in https://github.com/medusajs/medusa/pull/3979 * feat(medusa, inventory): Search inventory items by title and description by @pKorsholm in https://github.com/medusajs/medusa/pull/4154 * fix(medusa): Upserting tax rates (#4189) by @olivermrbl in https://github.com/medusajs/medusa/pull/4189 * chore(medusa,admin-ui): Add reservations FF by @olivermrbl in https://github.com/medusajs/medusa/pull/4184 ### Bugs * fix(medusa-payment-stripe): Added withTransaction to capturePaymentIfNecessary by @DidierGuyon in https://github.com/medusajs/medusa/pull/3930 * fix(medusa): downgrade `papaparse` version by @fPolic in https://github.com/medusajs/medusa/pull/4174 * fix(admin-ui): Ensure that default invite link uses __BASE__ if set by @kasperkristensen in https://github.com/medusajs/medusa/pull/4173 * fix(admin-ui): Ensure order of variant options matches order of product options by @kasperkristensen in https://github.com/medusajs/medusa/pull/4178 * fix(admin-ui): Delete variant by @olivermrbl in https://github.com/medusajs/medusa/pull/4163 * fix(inventory): Use correct table name in migration by @pKorsholm in https://github.com/medusajs/medusa/pull/4155 * fix(medusa): migrations cli should also pull from ${plugin}/dist by @dwene in https://github.com/medusajs/medusa/pull/3956 * fix(admin-ui): Omit purchasable variant prop on duplicate by @olivermrbl in https://github.com/medusajs/medusa/pull/4180 ### Chores * chore(medusa): Align build query utils by @adrien2p in https://github.com/medusajs/medusa/pull/4148 * chore(utils): clean util package deps by @fPolic in https://github.com/medusajs/medusa/pull/4146 ### New Contributors * @juanzgc made their first contribution in https://github.com/medusajs/medusa/pull/4094 * @DidierGuyon made their first contribution in https://github.com/medusajs/medusa/pull/3930 * @tomekpur made their first contribution in https://github.com/medusajs/medusa/pull/4040 **Full Changelog**: https://github.com/medusajs/medusa/compare/v1.11.0...v1.12.0
