We were using a global ValidationPipe in main.ts. This is an issue as
@Controllers should return HttpExecption and @Resolvers should return
GraphqlErrors
Removing the global pipe and creating a ResolverValidationPipe able to
generate GraphqlError. We also need to handle the exception in a filter
to avoid nest to think it's unhandled and make it flow to logs
Next step:
- it would be nice to have both @UsePipes(ResolverValidationPipe) +
@UseFilters(GraphqlValidationExceptionFilter) come together. This should
be possible if we create a @GraphQLResolver annotation
related to https://github.com/twentyhq/core-team-issues/issues/601
## Done
- add a `onDbEvent` `Subscription` graphql endpoint to listen to
database_event using what we have done with webhooks:
- you can subscribe to any `action` (created, updated, ...) for any
`objectNameSingular` or a specific `recordId`. Parameters are nullable
and treated as wildcards when null.
- returns events with following shape
```typescript
@Field(() => String)
eventId: string;
@Field()
emittedAt: string;
@Field(() => DatabaseEventAction)
action: DatabaseEventAction;
@Field(() => String)
objectNameSingular: string;
@Field(() => GraphQLJSON)
record: ObjectRecord;
@Field(() => [String], { nullable: true })
updatedFields?: string[];
```
- front provide a componentEffect `<ListenRecordUpdatesEffect />` that
listen for an `objectNameSingular`, a `recordId` and a list of
`listenedFields`. It subscribes to record updates and updates its apollo
cached value for specified `listenedFields`
- subscription is protected with credentials
## Result
Here is an application with `workflowRun`
