Version: 6.4

Upgrading from 5 to 6

npm install --save rest-hooks@6 @rest-hooks/rest@3

Highlights​

Package compatibility​

Be sure to upgrade these packages prior to upgrading Rest Hooks itself. They maintain compatibility with rest hooks 5.

Upgrade at the same time:

@rest-hooks/rest 3.0 drops compatibility with older versions, so this will have to be upgraded in unison. All breaking changes are listed below

caution

Due to a bug in npm 7, it might install multiple peerDeps (@rest-hooks/normalizr). If this happens, you can fix by completely uninstalling rest hooks packages and then reininstalling:

npm uninstall rest-hooks @rest-hooks/rest
npm install --save rest-hooks@6 @rest-hooks/rest@3

Exports moved to @rest-hooks/legacy.​

FlatEntity, SimpleRecord, NestedEntity, schemas, isEntity, Entity, Resource, SimpleResource, SchemaDetail, SchemaList, Method

These are still supported! They are simply moved to @rest-hooks/legacy. This allows smooth incremental migrations.

  1. yarn add @rest-hooks/[email protected]

    has all of these, and is compatible with both rest-hooks 5 and 6.

  2. Upgrade rest-hooks to 6 & @rest-hooks/legacy to 3.

  3. Gradually migrate to @rest-hooks/rest

Importing directly from hidden files is no longer supported​

All packages now use package exports, which if supported disallow importing directly from any sub path like rest-hooks/lib/react-integration/hooks/useSuspense

Doing this was never supported as file locations would change without announcement. However, now with tooling that supports package exports, it will not work at all.

Store state internals​

Entities no longer normalize to their class. Class construction is now done during denormalization step. This means the internal state of Rest Hooks is a POJO. This improves serialization. However, it does mean relying on the internal state in a Manager to be a class will break. Additionally the expected serialization of Rest Hooks store will be slightly different, which could affect snapshot tests or persistance efforts like using IndexedDB.

@rest-hooks/endpoint changes​

SimpleRecord -> Object

SimpleRecord was removed (though available in @rest-hooks/legacy)

Object can be used instead

export class Address extends SimpleRecord {
  readonly street: string = '';
  readonly suite: string = '';
  readonly city: string = '';
  readonly zipcode: string = '';
  readonly createdAt: Date = new Date(0);

  static schema = {
    createdAt: Date,
  };
}

@rest-hooks/rest changes from 2 -> 3​

These add on to the existing changes of @rest-hooks/rest from @rest-hooks/legacy

  • If Resource.fromJS() was used to customize normalization process, use process() instead.

     class MyResource extends Resource {
       static process(input: any, parent: any, key: string | undefined): any {
         return {
           ...input,
           extraThing: 5,
         };
       }
     }

  • New default error behavior

    To keep existing
    class MyResource extends Resource {
      static getEndpointExtra(): EndpointExtraOptions | undefined {
        return {
          errorPolicy: error => 'soft' as const,
        };
      }
    }

Full list of changes​

Node >=12​

Node 12 is now the minimum version required. This only applies if Rest Hooks is actually used within node. (SSR or testing are likely cases.)

@rest-hooks/endpoint​

Entity​

  • fromJS() -> process() to customize init
  • normalize results in POJO rather than instances
    • This is only meaningful for those inspecting the rest hooks state directly
  • FlatEntity, SimpleRecord removed (use @rest-hooks/legacy)

@rest-hooks/rest​

  • peerDep @rest-hooks/endpoint > 2

@rest-hooks/core​

  • buildInferredResult -> inferResults

  • Error behavior

    • useError() will no longer create synthetic errors for missing entities

    • useError() errorPolicy

      EndpointExtraOptions​

      interface EndpointExtraOptions {
        //...rest
        errorPolicy?: (error: any) => 'soft' | undefined;
      }

      'soft' vs undefined​

      • 'soft' avoids errors if existing results are still available (even if stale)
      • undefined (hard error) means any error always falls

      @rest-hooks/rest​

      New default policy: 5xx are soft, else hard.

      @rest-hooks/rest is where errors have 'status' members. This concept does not exist in base Endpoints.

        static getEndpointExtra(): EndpointExtraOptions | undefined {
          return;
          return {
            errorPolicy: error =>
              error.status >= 500 ? ('soft' as const) : undefined,
          };
        }

      PollingSubscription​

                // never break when data already exists
                errorPolicy: () => 'soft' as const,

      @rest-hooks/legacy - Resource​

      Existing policy was to always be 'soft' no matter what. This maintains that behavior.

        /** @deprecated */
        /** Get the request options for this SimpleResource  */
        static getFetchOptions(): FetchOptions | undefined {
          return {
            errorPolicy: () => 'soft' as const,
          };
        }

      https://github.com/data-client/rest-hooks/pull/971

    • polled fetch errors are always 'soft'

    • @rest-hooks/rest

      • 5xx: 'soft'
      • 4xx, 3xx, etc: 'hard'

  • peerDep @rest-hooks/endpoint > 2

rest-hooks​

Removed exports from 'rest-hooks': NestedEntity, schemas, isEntity, Entity, Resource, SimpleResource, SchemaDetail, SchemaList, Method

  • use @rest-hooks/legacy, or @rest-hooks/rest instead

@rest-hooks/legacy​

  • peerDep @rest-hooks/endpoint > 2
