# Getting Started

> Get started with the Context7 TypeScript SDK

<Warning>
  **Work in Progress**: This SDK is currently under active development. The API is subject to change and may introduce breaking changes in future releases.
</Warning>

# Getting Started

`@upstash/context7-sdk` is a TypeScript SDK for Context7, enabling easier access to library documentation with full type coverage.

Using `@upstash/context7-sdk` you can:

* Search across available libraries
* Get documentation context for any library
* Access library metadata including trust scores and versions

You can find the Github Repository [here](https://github.com/upstash/context7/tree/master/packages/sdk).

## Install

<CodeGroup>
  ```shell npm theme={null}
  npm install @upstash/context7-sdk
  ```

  ```shell pnpm theme={null}
  pnpm add @upstash/context7-sdk
  ```

  ```shell yarn theme={null}
  yarn add @upstash/context7-sdk
  ```

  ```shell bun theme={null}
  bun add @upstash/context7-sdk
  ```
</CodeGroup>

## Usage

### Initializing the Client

To use the Context7 SDK, you need an API key. You can get your API key from the [Context7 Dashboard](https://context7.com/dashboard).

#### Using environment variables

The SDK automatically reads from environment variables if no API key is provided in the config:

```bash theme={null}
CONTEXT7_API_KEY="your_api_key_here"
```

When an environment variable is set, you can initialize the client without any parameters:

```typescript theme={null}
import { Context7 } from "@upstash/context7-sdk";

const client = new Context7();
```

#### Using a configuration object

If you prefer to pass configuration in code, the constructor accepts a config object containing the apiKey value. This could be useful if your application needs to interact with multiple projects, each with a different configuration.

```typescript theme={null}
import { Context7 } from "@upstash/context7-sdk";

const client = new Context7({
  apiKey: <CONTEXT7_API_KEY>,
});
```

<Note>
  The SDK checks for API keys in this order: 1. `config.apiKey` (if provided) 2.
  `process.env.CONTEXT7_API_KEY`
</Note>

## Quick Start Example

```typescript theme={null}
import { Context7 } from "@upstash/context7-sdk";

const client = new Context7();

// Search for libraries
const libraries = await client.searchLibrary(
  "I need to build a UI with components",
  "react"
);
console.log(`Found ${libraries.length} libraries`);
console.log(libraries[0].id); // "/facebook/react"

// Get documentation as JSON array (default)
const docs = await client.getContext(
  "How do I use hooks?",
  "/facebook/react"
);
console.log(docs[0].title, docs[0].content);

// Get documentation context as plain text
const context = await client.getContext("How do I use hooks?", "/facebook/react", {
  type: "txt",
});
console.log(context);
```

## Error Handling

The SDK throws `Context7Error` for API errors:

```typescript theme={null}
import { Context7, Context7Error } from "@upstash/context7-sdk";

const client = new Context7();

try {
  const context = await client.getContext("query", "/invalid/library");
} catch (error) {
  if (error instanceof Context7Error) {
    console.error("Context7 API Error:", error.message);
  } else {
    console.error("Unexpected error:", error);
  }
}
```
