Aim

Generate corresponding TypeScript d.ts codes according to js codes generated by grpc_tools_node_protoc.

More information about grpc_tools_node_protoc (grpc-tools):

• npm
• source code
• doc how to use

And the versions over 3.0.0 support @grpc/grpc-js(grpc-tools@1.8.1 required). Please read the doc: @grpc/grpc-js support. New version 5.0.0 is recommended for users who using grpc-tools over v1.9.0.

Breaking changes

v5.3.0

Since @grpc/grpc-js@1.2.0 fixed the signature issue of handleClientStreamingCall exporting. It's no longer necessary to import it manually in *_pb.d.ts files like:

import {handleClientStreamingCall} from "@grpc/grpc-js/build/src/server-call";

Users who are using versions lower than @grpc/grpc-js@1.2.0 would be impacted, need to upgrade.

v5.2.0

Add support for proto3 optional. grpc-tools version of 1.11.1 is REQUIRED. See: Issue#88 and PR#97.

v5.1.0

Fix server implementation signature issue of grpc_js side. See: Issue#79.

About the code changes, please read the doc at Changes part. Also, please read this doc for more information: @grpc/grpc-js server implementation signature issue.

v4.0.0

Fix the issues along with grpc-tools@1.9.0, see: PR#55. If you are using grpc-tools with version under 1.9.0, you should NOT upgrade.

Also, if you want to use chain setters, you have to upgrade the version of package google-protobuf to at least 3.10.0. See the difference: v3.9.0 vs v3.10.0.

v2.4.0

The return value of type ClientReadableStream was wrong previously. And has been fixed in this version. Please be careful to update your code. See detail: PR#30.

v2.2.0

Fix definition changes according to the version change of grpc official TypeScript definition, see: index.d.ts@1.9.0.
Detailed changes could be found here: PR#14.

v2.0.0

Since v2.x.x, current project supports the official definition of grpc, see: index.d.ts@1.8.4.
Though the usage of tool, and generated codes shall not been changed, it's good to be double checked in your project when upgrade.

TSLint has been disabled in generated files. Please see the conversation: #13.

How to use

npm install grpc_tools_node_protoc_ts --save-dev

# generate js codes via grpc-tools

Changes

5.3.2

Fix wrong oneof name issue. See: Issue#113 and PR#116.

5.3.1

Update doc and Add runnable example for magic generics class style server implementation. See Issue#79 and Issue#108 and PR#109.

Updated doc could be found here: @grpc/grpc-js server implementation signature issue.

5.3.0

Fix signature issue of handleClientStreamingCall exporting. See PR#105.

Since @grpc/grpc-js@1.2.0 fixed the signature issue of handleClientStreamingCall exporting. It's no longer necessary to import it manually in *_pb.d.ts files like:

import {handleClientStreamingCall} from "@grpc/grpc-js/build/src/server-call";

Users who are using versions lower than @grpc/grpc-js@1.2.0 would be impacted, need to upgrade.

5.2.2

Fix vulnerabilities. See: PR#102.

5.2.1

Remove lib handlebars-helpers. PR#98.

5.2.0

Add support for proto3 optional. grpc-tools version 1.11.1 is RQUIRED. See: Issue#88 and PR#97.

Some info:

• google-protobuf changes: https://github.com/protocolbuffers/protobuf/blob/master/CHANGES.txt
• google-protobuf releases: https://github.com/protocolbuffers/protobuf/releases
• grpc-tools releases: https://github.com/grpc/grpc-node/releases

5.1.3

Fix wrong publishing, 5.1.2 contains some temp compiled codes. See: Issue#89.

5.1.2

Fix Extension and JsPbMessageId issue, see: Issue#84, and PR#87.

5.1.1

Add docs to explain previous breaking change a bit more. See: PR#82.

5.1.0

Fix server implementation signature issue of grpc_js side. See: Issue#79.

Breaking change, only grpc_js side would be affected.

The interface of service server now extends grpc.UntypedServiceImplementation (examples/src/grpcjs/proto/book_grpc_pb.d.ts).

// from
export interface IBookServiceServer {}

// to
export interface IBookServiceServer extends grpc.UntypedServiceImplementation {}

And the server implementation have to add a line of codes:

class ServerImpl implements IBookServiceServer {
    [name: string]: grpc.UntypedHandleCall;
    // others ...
}

If this line of code not added, there will be some error:

TS2420: Class 'ServerImpl' incorrectly implements interface 'IBookServiceServer'.
  Index signature is missing in type 'ServerImpl'.

Have a look at: Typescript: Index signature is missing in type.

Or, you can switch the server implementation from Class style to Object style:

const ServerImpl: IBookServiceServer = {
  // implementations
}

Object style requires no additional statement, and can be appended with more attributes.

Also, please read this doc for more information: @grpc/grpc-js server implementation signature issue.

5.0.1

Fix array.includes issue. See: Issue#73, Commit#1e4ae67.

5.0.0

Migrating to option grpc_js from grpc-tools@1.9.0.

Two points:

• Using option grpc_js in grpc_tools_node_protoc ... --grpc_out=grpc_js:...
• Style of generated js codes looks like traditional grpc_tools_node_protoc ... --plugin=protoc-gen-grpc=which grpc_tools_node_protoc_plugin

Difference between grpc-tools version 1.8.1 and 1.9.0, and also between generate_package_definition and grpc_js could be found here: @grpc/grpc-js support @5.0.0.

Users who are still using version 3.0.0 - 4.1.5 would not be affected. In version 5.0.0 options generate_package_definition and grpc_js are all available.

Though, 5.0.0 is recommended for users who using grpc-tools@1.9.0 or over, don't forget to switch your option to grpc_js. And remember, if you switch the cli command option to grpc_js, you have to adjust your typescript implementation, see: examples/src/grpcjs.

See more details:

• PR#71
• Broken ts imports after moving to grpc-js #70
• Broken typescript exports after moving to @grpc/grpc-js#1600

4.1.5

Use string literal type for path. See: PR#69.

4.1.4

Add .npmignore to shrink the size of npm package. See: PR#65.

4.1.3

Update doc to solve issues like: Issue#63.

4.1.1 - 4.1.2

Update grpc-js example codes. Fix vulnerabilities of example packages. Fix type of third param of Client class, see: PR#62.

4.1.0

Switch the type of requestStream & responseStream in file *_grpc_pb.d.ts from boolean to true | false. See: PR#58.

4.0.0

grpc-tools@1.9.0 changes the generated js codes a lot. Current version is released to fix the setters issue, see: PR#55. Note: This is a breaking change, if you are still using grpc-tools with version under 1.9.0, you DO NOT need to upgrade, version 4.0.0 would break your codes.

Also, if you want to use chain setters, you have to upgrade the version of package google-protobuf to at least 3.10.0. See the difference: v3.9.0 vs v3.10.0.

3.0.0

@grpc/grpc-js now is supported. See: Issue#56. Users who still using grpc would NOT be affected. More detailed information, please go to @grpc/grpc-js support. Note: This upgrade requires grpc-tools version 1.8.1.

2.4.1

Use gRPC-native ServiceError objects for errbacks in client methods. See: PR#33.

2.4.0

2.2.5

Fix issue of reversed JavaScript keyword code generation. See: Issue#20 & PR#21.

2.2.4

Fix issue of conflicted I{$MethodName} name, see: Issue#19.

2.2.3

Fix definitions. fix: add missing argument grpc.Client~CallOptions for requests

About jstype options of protobuf

JavaScript can safely handle numbers below Number.MAX_SAFE_INTEGER. Beyond the limit, it begins to overflow:

> 90071992547409912131 + 1
90071992547409920000

If you are expecting large, 64bit fields consider using a jstype option to override the field type.

# example.proto
message Example {
  fixed64 id = 1 [jstype = JS_STRING];
}

// example_pb.d.ts
export namespace Example {
    export type AsObject = {
        id: string
    }
}

About vulnerability

Since this tool is used to generate typescript signature for the codes generated from grpc_tools_node_protoc, the codes actually run with your application are from grpc_tools_node_protoc, not this tool. So it's still safe to be used even there are some vulnerabilities in it.

If you want your project to have no vulnerabilities detected, you could simply install this tool into global (out of your application project). And use it when you want to generate the typescript signature in development as usual.

About Docker

Sample below, just the idea, not perfect. Also some more info: Issue#38.
