Package Exports
- hyperledger-fabric-chaincode-helper
- hyperledger-fabric-chaincode-helper/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hyperledger-fabric-chaincode-helper) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Built-in DID requests.
Methods
getTimestamp(ctx): number
getUniqueClientId(ctx): string
getParams(ctx, rules): Array
exists(ctx, id): Promise
getAllResultsFromIterator(iterator, isHistory, limit): Promise<Array>
Example
import { BlockotusContract } from 'hyperledger-fabric-chaincode-helper';
class MyContract extends BlockotusContract {
public async anyfunction(ctx) {
const timestamp = this.getTimestamp(ctx);
const uniqueClientId = this.getUniqueClientId(ctx);
const params = this.getParams(ctx, { length: 2 });
const exists = await this.exists(ctx, id);
const results = await this.getAllResultsFromIterator(iterator, false, 5); // in a Write transaction, Fabric does not support Limit Queries. This helper does the job.
}
/**
* Cross-contract invokeChaincode() does not support Parent Contract method as far as I know.
