Nifty gRPC
Call gRPC services from .grpc files and edit .proto files: unary and streaming calls, metadata, TLS, request templates from your protos, outline and error checking.
Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.
Features
- gRPC calls as text files. Write calls in
.grpc files, commit them next to your protos, and click Send gRPC Request (Ctrl+Alt+R). No separate app, no account.
- Every kind of call. Unary, server streaming, client streaming (send a JSON array of messages) and bidirectional streaming, with metadata, deadlines and TLS.
- Your protos, found for you. Nifty gRPC finds the
.proto that declares the service in your workspace, including its imports. Or point at one with # @proto ./api/shop.proto.
- A clear response view. Status code and name, timing, every streamed message as colored JSON, response headers and trailers, and the exact request that was sent.
- Try it from the proto. A Try it link above every
rpc in a .proto file writes a ready-to-send request, with every field of the request message filled in with a sample value, including nested messages, enums and repeated fields.
.proto editing: syntax highlighting, outline and breadcrumbs for messages, enums, services and rpcs, and syntax errors as you type.- Variables:
@host = localhost:50051 then {{host}}, plus {{$uuid}}, {{$timestamp}} and {{$env.TOKEN}}.
- Service/method completion on the
GRPC line, from every proto in the workspace.
Example
@host = localhost:50051
### Get an item
# @deadline 5s
GRPC {{host}} shop.v1.Catalog/GetItem
authorization: Bearer {{$env.TOKEN}}
{ "id": "42" }
### Upload several (client streaming)
GRPC {{host}} shop.v1.Catalog/AddItems
[{ "name": "Mug" }, { "name": "Lamp" }]
Local addresses use plaintext and anything else uses TLS, unless you write grpc:// / grpcs:// or add # @insecure / # @tls.
