npm install @nidomiro/relation-tuple-parser-ory-keto
This library is the same as @nidomiro/relation-tuple-parser but uses grpc types of ory keto.
``ts
import { parseRelationTuple } from '@nidomiro/relation-tuple-parser'
import { KetoGrpcConverter, KetoHttpConverter } from '@nidomiro/relation-tuple-parser-ory-keto'
const result = parseRelationTuple('sharedFiles:a.txt#access@(dirs:b#access)').unwrapOrThrow()
const grpcRelationTuple = KetoGrpcConverter.createRelationTuple(result)
const grpcCheckRequest = KetoGrpcConverter.createCheckRequest(result)
const httpRelationTuple = KetoHttpConverter.createRelationTuple(result)
const httpRelationQuery = KetoHttpConverter.createRelationQuery(result)
`
It is also possible to parse the Relation tuple in a structure where different placeholders can be replaced.
This is especially useful if you define a Guard via Decorators but require som dynamic replacements e.g. for the id of
the current user.
`ts
import { parseRelationTupleWithReplacements } from '@nidomiro/relation-tuple-parser'
import { KetoGrpcConverter } from '@nidomiro/relation-tuple-parser-ory-keto'
const result = parseRelationTupleWithReplacements(({ userId }) => groups:admin#member@${userId})
/**
* Contains the "Template" of the Relation tuple with the replacements defined above.
* Calculate this once and use it on every evaluation.
*/
const valueWithreplacements = result.unwrapOrThrow()
/**
* Execute this at evaluation time (e.g. every incomming Request) to get the actual ory Relation tuple send to keto via grpc.
*/
const grpcCheckRequest = KetoGrpcConverter.createCheckRequest(valueWithreplacements, {
userId: 'my_user_id',
})
