library0.1.4jsnpmunverified

A simple wrapper for gRPC client in Node.js (v0.1.4, last release 2016). It provides a fluent API to load proto files and make gRPC calls with promise-based responses. Minimal maintenance; only one release. Simpler than @grpc/grpc-js but outdated and not actively supported.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

gRPCClient (default)
✓ var grpcClient = require('grpc-client');
✗ import grpcClient from 'grpc-client';
CommonJS only; no ESM support. The library exports a constructor function directly.
instance methods
✓ var gc = new grpcClient({host: 'localhost:50051', dir: './'});
✗ var gc = grpcClient({host: 'localhost:50051', dir: './'});
Must use 'new' keyword to instantiate the client.

Initialize gRPC client, load a proto file, and make a unary RPC call with promise handling.

var grpcClient = require('grpc-client'); var gc = new grpcClient({host: "localhost:50051", dir: './', header: {custom: ['customvalue']}}); gc.proto("helloworld") .sayHello({name:"xing"}) .then(function(res){ console.log(res); }) .catch(function(err){ console.log(err); });
Debug
Known issues
deprecatedPackage is unmaintained; use @grpc/grpc-js instead.
fix
Replace with @grpc/grpc-js which is actively maintained.
affects: >=0.0.0
breakingDependency 'grpc' (the legacy gRPC package) has breaking changes with newer Node versions.
fix
Migrate to @grpc/grpc-js which is pure JS and works with Node >= 8.
affects: >=0.0.0
gotchaThe 'header' option expects an object with string arrays, e.g., {custom: ['value']}.
fix
Ensure headers are passed as an object with array values.
affects: >=0.1.4
Errors
Common errors & fixes
Cannot find module 'grpc-client'
Package not installed or npm install failed.
fix

TypeError: grpcClient is not a constructor
Using the module without 'new' keyword.
fix
