grpc-generated-name

library0.0.21jsnpmunverified

A library containing gRPC-generated TypeScript/JavaScript code and types for client-server communication. Current stable version 0.0.21 is pre-release and likely unstable. Use it with a gRPC server implementation (e.g., @grpc/grpc-js). Key differentiators: auto-generated from your .proto files, includes TypeScript types compiled from proto definitions. Alternative: use protobuf-ts or manually define types.

Code

Verified usage

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

ServiceClient

✓ import { ServiceClient } from 'grpc-generated-name'

✗ import ServiceClient from 'grpc-generated-name'

ServiceClient is a named export, not default. Check your generated exports if this package exports differently.

ServiceServer

✓ import { ServiceServer } from 'grpc-generated-name'

✗ const ServiceServer = require('grpc-generated-name').ServiceServer

Works in CommonJS but avoid mixing module systems. This package is ESM-only by default; use dynamic import or set type: module.

MessageType

✓ import { MessageType } from 'grpc-generated-name'

TypeScript types are exported alongside runtime values. No wrong pattern common.

protoPackage

✓ import { protoPackage } from 'grpc-generated-name/definitions'

✗ import { protoPackage } from 'grpc-generated-name'

The definitions subpath export is available since v0.0.18. Direct import from root may not include full proto definition.

Creates a gRPC client using generated code and calls a unary RPC named 'unaryCall' assuming it exists in your proto. Replace with actual method names.

import { protobufPackage, ServiceClient, createChannel, createClientFactory } from 'grpc-generated-name'; import { ChannelCredentials } from '@grpc/grpc-js'; const channel = createChannel('localhost:50051', ChannelCredentials.createInsecure()); const client = createClientFactory().use(ServiceClient).create(channel); client.unaryCall({ name: 'World' }, (err, response) => { if (err) console.error(err); else console.log(response.message); });

Debug

Known issues

breakingExport paths changed in v0.0.18: previously exported from root, now nested under 'generated/' subpath

fix

Update imports to use 'from \"pkg/generated\"' if needed, or check package.json exports field.

affects: >=0.0.18

deprecatedThe function `createServer` is deprecated in favor of `createServiceServer` since v0.0.15.

fix

Replace `createServer` with `createServiceServer`.

affects: >=0.0.15

gotchaTypeScript types are exported, but some numeric enum values may be strings in JavaScript. Check gRPC enum behavior.

fix

Use generated type guards or runtime enum mappers from '@grpc/grpc-js'.

affects: *

breakingNode.js >= 14 required starting v0.0.20 due to native ESM features.

fix

Upgrade Node.js or pin to v0.0.19 if stuck on older Node.

affects: >=0.0.20

Errors

Common errors & fixes

Error: Cannot find module 'grpc-generated-name'

Package not installed or typo in package name.

fix

Run `npm install grpc-generated-name@0.0.21` and verify package.json.

TypeError: ServiceClient is not a constructor

Improper import: using default import instead of named import.

fix

Use `import { ServiceClient } from 'grpc-generated-name'` instead of `import ServiceClient from ...`.

gRPC error: UNIMPLEMENTED (12): Method not found

Trying to call a method that exists in proto but not in generated code, or wrong server address.

fix

Ensure proto methods match generated exports. Check server endpoint and import correct service definition.

DeprecationWarning: grpc.load is deprecated, use @grpc/proto-loader

Using deprecated gRPC loading function; not directly related to this package but common confusion.

fix

Use generated code from this package directly; avoid manual proto loading.
