Node.js gRPC Library

Status

Beta

PREREQUISITES

• node: This requires node to be installed. If you instead have the nodejs executable on Debian, you should install the nodejs-legacy package.

INSTALLATION

Install the gRPC NPM package

npm install grpc

BUILD FROM SOURCE

1. Clone the grpc Git Repository.
2. Run npm install.

TESTING

To run the test suite, simply run npm test in the install location.

API

This library internally uses ProtoBuf.js, and some structures it exports match those exported by that library

If you require this module, you will get an object with the following members

function load(filename)

Takes a filename of a Protocol Buffer file, and returns an object representing the structure of the protocol buffer in the following way:

• Namespaces become maps from the names of their direct members to those member objects
• Service definitions become client constructors for clients for that service. They also have a service member that can be used for constructing servers.
• Message definitions become Message constructors like those that ProtoBuf.js would create
• Enum definitions become Enum objects like those that ProtoBuf.js would create
• Anything else becomes the relevant reflection object that ProtoBuf.js would create

function loadObject(reflectionObject)

Returns the same structure that load returns, but takes a reflection object from ProtoBuf.js instead of a file name.

function Server([serverOpions])

Constructs a server to which service/implementation pairs can be added.

status

An object mapping status names to status code numbers.

callError

An object mapping call error names to codes. This is primarily useful for tracking down certain kinds of internal errors.

Credentials

An object with factory methods for creating credential objects for clients.

ServerCredentials

An object with factory methods for creating credential objects for servers.
