How to Install and Use gpt-crawler 🛠️

In this section, we will detail how to install and use the gpt-crawler project, enabling you to quickly get started with this powerful open-source tool.

1. Clone the Project 🌿

First, you need to clone the gpt-crawler project from GitHub to your local machine. Run the following command in your terminal:

git clone https://github.com/builderio/gpt-crawler

This command downloads all the code and files for gpt-crawler from the GitHub server, allowing you to access and modify these files locally for your personalized development! 🌍

2. Install Dependencies 📦

Once downloaded, navigate to the project directory and install the required dependencies:

cd gpt-crawler
npm install

When you run this command, npm will automatically read the package.json file in the project and download all necessary dependencies. This ensures your application runs smoothly, avoiding many potential errors 😅.

3. Start the Server 🚀

After installing all dependencies, you can start the application with the following command:

npm start

At this point, gpt-crawler’s server will be running on the default port 3000. You can use the /crawl endpoint to send POST requests to initiate the crawler, and the API documentation can be found at /api-docs, which is very convenient! 📄

4. Run Using Docker ⚓

If you prefer managing the runtime environment with Docker, gpt-crawler supports that too! You can find detailed guidance on how to run the project within a container in the containerapp/README.md file, which is a big plus for users who enjoy containerized deployments! 🐳

5. Create a Custom GPT 🎨

Want to create a custom GPT using the data generated by the crawler? No worries! Just follow these steps:

1. Go to the OpenAI chat interface
2. Click on your name in the lower-left corner
3. Select “My GPTs”
4. Click “Create a GPT”
5. Choose “Configure”
6. In the “Knowledge” section, select “Upload a file” and upload the file you generated earlier

You’ll be able to personalize your GPT, making it more suited to your needs! 🧠

6. Create a Custom Assistant 👩‍💻

Similarly, if you want to create a custom assistant, the steps are quite simple:

1. Visit the OpenAI assistant platform
2. Click “+ Create”
3. Select “Upload” and upload the generated file

This will equip your assistant with more thematic knowledge from the source code, which is absolutely fantastic! 💡

Detailed Code Annotations and Explanations 🔍

Next, we’ll delve deeper into some code within gpt-crawler so you can better understand how it works.

Configuration File 📄

In the project, a default configuration is defined:

export const defaultConfig: Config = {
  url: "https://www.builder.io/c/docs/developers",  // Starting URL for the crawler
  match: "https://www.builder.io/c/docs/**",  // URL pattern for matching, limiting the crawler's target pages
  selector: `.docs-builder-container`,  // CSS selector used to extract content of interest from the page
  maxPagesToCrawl: 50,  // Sets the maximum number of pages to crawl
  outputFileName: "output.json",  // File name for saving the output results
};

Here, we define a defaultConfig object that includes multiple properties to configure crawling behavior. 🌟

• url: The web address the crawler will visit initially.
• match: The URL pattern used for filtering unnecessary pages, ensuring we only crawl the content we need.
• selector: A CSS selector to determine the area to extract content from.
• maxPagesToCrawl: Specifies the maximum number of pages the crawler can visit to avoid prolonged crawling times.
• outputFileName: This is where the data collected by the crawler will be saved.

Starting the Crawler 🥳

To start the crawler, use the following command:

npm run start:server

Executing this command will start the crawler server, allowing you to run crawler tasks by sending POST requests to /crawl 🎉.

Sample Output 📊

The output after crawling will be saved in JSON format, structured as follows:

[
  {
    "title": "Creating a Private Model - Builder.io",  // Page title
    "url": "https://www.builder.io/c/docs/private-models",  // Page link
    "html": "..."  // HTML code of the page content, abbreviated with "..."
  },
  {
    "title": "Integrating Sections - Builder.io",
    "url": "https://www.builder.io/c/docs/integrate-section-building",
    "html": "..."
  },
  ...
]

This structured JSON data is easy to parse and utilize, significantly enhancing data retrieval efficiency and ease of use 💼.

With the above steps and code annotations, you should now be able to successfully install and use the gpt-crawler project, while gaining a comprehensive understanding of its core code structure and meaning. If you encounter any issues along the way, the official documentation is your best friend! 🗂️
