# Pure JavaScript gRPC Client

**Note: This is an beta-level release. Some APIs may not yet be present and there may be bugs. Please report any that you encounter**

## Installation

Node 10 is recommended. The exact set of compatible Node versions can be found in the `engines` field of the `package.json` file.

```sh
npm install @grpc/grpc-js
```

## Features

 - Unary and streaming calls
 - Cancellation
 - Deadlines
 - TLS channel credentials
 - Call credentials (for auth)
 - Simple reconnection
 - Channel API

This library does not directly handle `.proto` files. To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package.

## Some Notes on API Guarantees

The public API of this library follows semantic versioning, with some caveats:

 - Some methods are prefixed with an underscore. These methods are internal and should not be considered part of the public API.
 - The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API.
 - In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API.
