Breaking :warning:

Appollo Client v3 Cache Behavior for GraphQL Mutations

Prior to this version, Redwood Cells used Apollo’s cache and network fetch policy. This has been removed in favor of the default policy (see #1250). This change, along with the new Apollo v3 behavior, changes the behavior of mutations — state changes will often not render without a page reload.

From the ApolloDocs: If a mutation modifies multiple entities, or if it creates or deletes entities, the Apollo Client cache is not automatically updated to reflect the result of the mutation.

tl;dr : if things with your App’s CRUD rendering seem broken after upgrading, you’ll need to update the Mutations in your components to use Apollo’s new features like refetchQueries :

Prisma Query Engine Deploy Error

Prisma v2.9.0 now requires setting an additional binaryTarget in schema.prisma . Otherwise, the Prisma query engine will not build correctly, resulting in an error affecting the production deploy.

How to upgrade RedwoodJS to v0.20.0

:point_right: IMPORTANT: Skipping versions when upgrading is not recommended and will likely cause problems. Do read through all Release Notes between your current version and this latest version. Each minor release will likely require you to implement breaking change fixes and apply manual code modifications.

Manual Code Modifications

  1. Prisma v2.9 requires an additional binaryTarget for production deploys to build correctly:
    • add the additional binaryTarget "rhel-openssl-1.0.x" to api/prisma/schema.prisma
    • see this example
  2. VS Code GraphQL extension required config:
  3. Update Scaffold generated Component files (or, in some cases, your own custom mutation implementations)
    • Redwood Scaffold generated CRUD needs to be updated in order to work with the new Apollo v3 Cache. There are four generated component files that need to be updated for each generated Scaffold. The specific names will be different based on your schema models. For the Tutorial post model as an example, the files to update are the components /Post/Post.js , /Posts/Posts.js , /NewPost/NewPost.js , and /EditPostCell/EditPostCell.js
    • Note: One way to handle this is to re-run Scaffold Generator with the --force option. :rotating_light: It’s the fastest. But this will overwrite any customization.
    • Edit [Model].js, [Model]s.js, and New[Model].js Components (e.g. Post.js, Posts.js, and NewPost.js):
      • See the three files in this commit for reference. Note: the reference file are Name.js.template , Names.js.template , and NewName.js.template
      • For each file, add import { QUERY } from 'src/components/${pluralPascalName}Cell'
      • For the respective DELETE and CREATE mutation’s onCompleted property, add refetchQueries: [{ query: QUERY }], awaitRefetchQueries: true,
      • For the [Model]s.js file, remove the current refetchQueries property from the onDeleteClick conditional
    • Edit the Edit[Model]Cell.js Component (e.g. EditPostCell.js):
      • See the EditNameCell.js.template file in this commit for reference
      • The UPDATE mutation requires passing all properties, not just id in the same manner as the QUERY
      • Add all QUERY properties (e.g. id , title , body , createdAt ) to the UPDATE_[Model]_MUTATION

Upgrading is worth it! And, more importantly, there’s a vibrant community for help (and encouragement) if you need it.

Successfully upgraded on my own project :tada:. Re-running the scaffold generator (using --force) for each of the models was smooth sailing. Don’t forget if you’re using @relation in your schema you’ll need to modify again as per https://redwoodjs.com/docs/schema-relations. Thanks for all the work that’s gone into this version! :raised_hands:
