Schema Operations

Create Schema

Create a new JSON-LD credential schema. This method allows users to define the structure and properties of the credential schema.

import { createSchema } from 'polygon-schema-manager'
const txDetails = await createSchema(did, schemaName, schema)

The function returns, did, schemaId,and txnReceipt.

Get Schema by ID

Retrieves schema details by its unique ID.

import { getSchemaById } from 'polygon-schema-manager'
const schemaDetail = await getSchemaById(did, schemaId)

The function returns Schema details including resourceURI, resourceCollectionId, etc..

Get All Schemas by DID

Retrieves all schemas associated with a specific DID.

import { getSchemaById } from 'polygon-schema-manager'
const schemaDetails = await getSchemaById(did)

The function returns Array of schema objects with essential keys..

Estimate Transaction

Estimates transaction fees for schema-related transactions.

import { estimateTxFee } from 'polygon-schema-manager'
const transactionDetails = await getSchemaById(did)

The function returns transaction details including transactionFee, gasLimit, etc.

Validate Schema Object

Validates the JSON schema object to ensure its correctness.

import { estimateTxFee } from 'polygon-schema-manager'
const transactionDetails = await getSchemaById(did)

The function returns boolean indicating whether the schema is valid.
