Summary
This fcl
connector is a wrapper around @onflow/transport-grpc
which uses real gRPC via @grpc/grpc-js
, not gRPC-web as the original.
Original transport has problems communicating with regular gRPC endpoints.
If the node url starts with http(s)://
it will fall back to using @onflow/transport-grpc
Status
This package is working and in active development, breaking changes may happen.
Usage
Install
npm install --save @mobile-reality/flow-transport-real-grpc
Integration with FCL
import { config } from "@onflow/fcl"
import { send as sendGrpc } from "@mobile-reality/flow-transport-real-grpc"
config({
"accessNode.api": "access.mainnet.nodes.onflow.org:9000",
"sdk.transport": sendGrpc
})
Experimental features
Node can be an array of nodes, in which case it will load balance between nodes using round robin. It recommended to perform loadbalancing yourself or using another library.
If you provide opts.serviceName
it will override the grpc service namespace in the call, allowing you for example to query execution node gRPC ('flow.execution.ExecutionAPI'
)
