Installing LlamaIndex via NPM: A Step-by-Step Guide
Are you ready to dive into the world of AI with LlamaIndex? If you're looking to install this nifty data framework designed for Large Language Models (LLMs), look no further! In this guide, we’ll walk you through the process of setting up LlamaIndex via NPM — all the while ensuring that you can seamlessly integrate it into your existing projects.
What is LlamaIndex?
LlamaIndex is a fantastic framework that enables you to build LLM-powered applications by helping you ingest, structure, and access private, domain-specific data. You can utilize it with various types of data sources, whether they’re APIs, PDFs, or just text files. It's particularly useful because it connects custom data sources to LLMs, allowing you to create remarkable applications without too much hassle.
Now, let’s jump right into how to install LlamaIndex using NPM!
Step 1: Prerequisites
Before you install LlamaIndex, ensure that you have the following:
A system with Node.js installed. You can download it from Node.js. We recommend having the latest version for the best performance.
Familiarity with using the command line!
Step 2: Install LlamaIndex via NPM
It's super easy! Just follow these steps:
Open your terminal or command prompt.
Run one of the following commands based on your preferred package manager:
With npm:
1
2
bash
npm install llamaindex
If you prefer using Yarn:
1
2
bash
yarn add llamaindex
Or for Pnpm users:
1
2
bash
pnpm install llamaindex
For JSR installation, you can use:
1
2
bash
jsr install @llamaindex/core
This will install LlamaIndex and all of its dependencies.
Step 3: Set Up Your Project Structure
After installation, it's good practice to set up the project structure. Here’s a simple guideline:
Create a directory for your project if you haven’t already. You can do this using:
1
2
3
bash
mkdir my-llama-project
cd my-llama-project
You can initialize a new Node.js project using:
1
2
bash
npm init -y
This generates a
1
package.json
file that keeps a track of your project's metadata and dependencies.
Step 4: Importing LlamaIndex
Now that you have LlamaIndex installed, let’s import it into your project. Here’s how to do this in a Node.js environment:
Create a new JavaScript file, let’s say
1
app.js
:
1
2
bash
touch app.js
Open that file in your favorite text editor.
At the top of
1
app.js
, import LlamaIndex:
1
2
javascript
import { Document, VectorStoreIndex } from 'llamaindex';
Step 5: Using LlamaIndex in Your Code
Let's add some code to utilize LlamaIndex effectively. For instance, here’s how you could load a document, create embeddings, and query it.
Let’s assume you have a text file named
1
doc.txt
in a
1
data
folder. You will load the content of this file into your application:
```javascript
import fs from 'fs/promises';
async function main() {
// Load the document
const text = await fs.readFile('./data/doc.txt', 'utf-8');
// Create a Document object
const document = new Document({ text });
// Create VectorStoreIndex from the document
const index = await VectorStoreIndex.fromDocuments([document]);
// Querying the index
const queryEngine = index.asQueryEngine();
const response = await queryEngine.query({ query: 'What is this document about?' });
console.log(response.toString());
}
main();
```
Make sure you have your
1
doc.txt
file with some text in it!
To execute your script, you can run:
1
2
bash
node app.js
This is just a simple script. You can expand it by adding more documents, connecting to external data sources, or building more complex queries based on your needs.
Step 6: Setting Up Environment Variables (Optional)
If you're using OpenAI with LlamaIndex, make sure to set your OpenAI API key as an environment variable. You can do this in your terminal:
