Proto2http

Proto2http provides a code generation tool to convert your protocol buffers (.proto) files into invokable HTTP request.

Usage

proto2http -path=your-file.proto -output=../generated_protos/ -baseurl=https://your-api-path.com -target=language-target

See proto2http -help for more detail.

Samples

Converted files from gRPC's official sample HelloWorld.proto invoked with command:

proto2http -path=test.proto -target=browser-ts -baseurl=http://test-api.com/

/**
 * The request message containing the user's name.
 */
type HelloRequest = {
    name: string
}

/**
 * The response message containing the greetings
 */
type HelloReply = {
    message: string
}

/**
 * The greeting service definition.
 */
export class GreeterClient {
    _baseUrl: string
    constructor(baseUrl?: string) {
        if (baseUrl === "" || baseUrl == null) {
            this._baseUrl = "http://test-api.com/";
        } else {
            this._baseUrl = baseUrl;
        }
    }

    /**
     * Sends a greeting
     */
    public async SayHello(input: HelloRequest): Promise<HelloReply> {
        const request = await fetch(
            new URL("SayHello", this._baseUrl).toString(),
            {
                method: "POST",
                headers: {
                    "Content-Type": "application/json",
                    "Accept": "application/json"
                },
                body: JSON.stringify(input),
            }
        );

        const body = await request.json();
        return body;
    }

}
