gRPC transport for the Trooba pipeline, version 1.2.0. This package provides both client and service (server) side gRPC transport implementations integrated with the Trooba pipe-and-filter architecture. It uses @grpc/grpc-js under the hood, supporting protobuf definitions and serialization. The release cadence is sporadic; the package has not been updated since 2020. Key differentiators: lightweight gRPC integration within Trooba pipelines, enabling middleware patterns like logging, authentication, and transformation for gRPC calls. Compared to standalone gRPC libraries, it leverages Trooba's composable pipeline model.

trooba-grpc-transport
✓ const grpcTransport = require('trooba-grpc-transport');
✗ import grpcTransport from 'trooba-grpc-transport';
Package does not ship TypeScript types; use commonjs require. ESM import may fail.
trooba
✓ const trooba = require('trooba');
Trooba is the pipeline framework; must be installed separately.
Grpc (from @grpc/grpc-js)
✓ const grpc = require('@grpc/grpc-js');
Used when loading proto files manually for service definition.

Shows how to create a gRPC client and server using Trooba pipeline with trooba-grpc-transport.

const trooba = require('trooba'); const grpcTransport = require('trooba-grpc-transport'); const grpc = require('@grpc/grpc-js'); const protoLoader = require('@grpc/proto-loader'); const PROTO_PATH = './hello.proto'; const port = 50051; // Client const client = trooba .use(grpcTransport, { protocol: 'http:', hostname: 'localhost', port: port, proto: protoLoader.loadSync(PROTO_PATH), connectTimeout: 100, socketTimeout: 1000 }) .build('client:default'); client.SayHello({ name: 'World' }, (err, response) => { if (err) console.error(err); else console.log('Greeting:', response.message); }); // Server (requires trooba helper) const server = trooba .use(grpcTransport, { port: port, hostname: 'localhost', proto: grpc.loadPackageDefinition(protoLoader.loadSync(PROTO_PATH)).hello }) .use(function handler(pipe) { pipe.on('request', (request, next) => { console.log('Received:', request.name); next(); }); }) .build('service');

Known issues
deprecatedThis package relies on @grpc/grpc-js which may have breaking changes in newer versions.
fix
Pin @grpc/grpc-js and @grpc/proto-loader versions compatible with this transport.
affects: >=1.0.0
gotchaThe package returns a function that must be passed to trooba.use() as a middleware. Do not call it directly.
fix
Use .use(grpcTransport, options) syntax.
affects: *
gotchaProto path must be resolved to an absolute path or loaded via proto-loader; relative paths may fail.
fix
Use require.resolve() or protoLoader.loadSync with full path.
affects: *
Errors
Common errors & fixes
Error: Cannot find module '@grpc/grpc-js'
@grpc/grpc-js is a peer dependency not automatically installed.
fix
Run: npm install @grpc/grpc-js @grpc/proto-loader
TypeError: trooba.use is not a function
Trooba is not installed or incorrectly imported.
fix
Install trooba: npm install trooba
Error: ENOENT: no such file or directory, open 'path/to/hello.proto'
Proto file path is relative and not resolved correctly.
fix
Use require.resolve('./hello.proto') or absolute path.
