@ydbjs/api/README.md

TypeScript gRPC service definitions and protobuf types for all YDB APIs. Enables strongly-typed client generation and low-level protocol access.

# @ydbjs/api

The `@ydbjs/api` package provides TypeScript/JavaScript bindings for interacting with YDB services. It includes generated gRPC service definitions and protocol buffer types for various YDB APIs.

## Features

- gRPC service definitions for YDB APIs
- Protocol buffer types for YDB entities
- TypeScript support with type definitions

## Installation

Install the package using npm:

```sh
npm install @ydbjs/api
```

## Usage

### Importing Services

```ts
import { DiscoveryServiceDefinition } from '@ydbjs/api/discovery'
import { CmsServiceDefinition } from '@ydbjs/api/cms'
import { QueryServiceDefinition } from '@ydbjs/api/query'
```

### Example: Using a Service

```ts
import { createClientFactory, createChannel } from 'nice-grpc'
import { DiscoveryServiceDefinition } from '@ydbjs/api/discovery'

const clientFactory = createClientFactory()
const discoveryClient = clientFactory.create(
  DiscoveryServiceDefinition,
  createChannel('http://localhost:2136')
)

async function listEndpoints() {
  const response = await discoveryClient.listEndpoints({ database: '/local' })
  console.log(response)
}

listEndpoints().catch(console.error)
```

### Using with @ydbjs/core

```ts
import { DiscoveryServiceDefinition } from '@ydbjs/api/discovery'
import { Driver } from '@ydbjs/core'

const driver = new Driver('grpc://localhost:2136')
const client = driver.createClient(DiscoveryServiceDefinition)
client.listEndpoints({ database: '/local' })
```

## Development

### Generating gRPC and Protocol Buffer Files

```sh
npm run generate
```
