Load Product Hunt data in Python using dltHub

Build a Product Hunt-to-database or-dataframe pipeline in Python using dlt with automatic Cursor support.

In this guide, we'll set up a complete Product Hunt data pipeline from API credentials to your first data load in just 10 minutes. You'll end up with a fully declarative Python pipeline based on dlt's REST API connector, like in the partial example code below:

Example code
@dlt.source
def product_hunt_source(access_token=dlt.secrets.value):
    config: RESTAPIConfig = {
        "client": {
            "base_url": "https://api.producthunt.com/v2/",
            "auth": {
                "type": "bearer",
                "token": access_token,
            },
        },
        "resources": [
            api/graphql, oauth/authorize
        ],
    }
    [...]
    yield from rest_api_resources(config)


def get_data() -> None:
    # Connect to destination
    pipeline = dlt.pipeline(
        pipeline_name='product_hunt_pipeline',
        destination='duckdb',
        dataset_name='product_hunt_data', 
    )
    # Load the data
    load_info = pipeline.run(product_hunt_source())
    print(load_info)

Why use dltHub Workspace with LLM Context to generate Python pipelines?

  • Accelerate pipeline development with AI-native context
  • Debug pipelines, validate schemas and data with the integrated Pipeline Dashboard
  • Build Python notebooks for end users of your data
  • Low maintenance thanks to Schema evolution with type inference, resilience and self documenting REST API connectors. A shallow learning curve makes the pipeline easy to extend by any team member
  • dlt is the tool of choice for Pythonic Iceberg Lakehouses, bringing mature data loading to pythonic Iceberg with or without catalogs

What you’ll do

We’ll show you how to generate a readable and easily maintainable Python script that fetches data from product_hunt’s API and loads it into Iceberg, DataFrames, files, or a database of your choice. Here are some of the endpoints you can load:

  • GraphQL API: Main endpoint for querying products, posts, comments, users, and other Product Hunt data
  • OAuth Authorization: Endpoint for user authentication and authorization flow

You will then debug the Product Hunt pipeline using our Pipeline Dashboard tool to ensure it is copying the data correctly, before building a Notebook to explore your data and build reports.

Setup & steps to follow

💡
Before getting started, let's make sure Cursor is set up correctly:

Now you're ready to get started!

  1. ⚙️ Set up dlt Workspace

    Install dlt with duckdb support:

    pip install dlt[workspace]

    Initialize a dlt pipeline with Product Hunt support.

    dlt init dlthub:product_hunt duckdb

    The init command will setup the necessary files and folders for the next step.

  2. 🤠 Start LLM-assisted coding

    Here’s a prompt to get you started:

    Prompt
    Please generate a REST API Source for Product Hunt API, as specified in @product_hunt-docs.yaml 
Start with endpoint(s) api/graphql and oauth/authorize and skip incremental loading for now. 
Place the code in product_hunt_pipeline.py and name the pipeline product_hunt_pipeline. 
If the file exists, use it as a starting point. 
Do not add or modify any other files. 
Use @dlt rest api as a tutorial. 
After adding the endpoints, allow the user to run the pipeline with python product_hunt_pipeline.py and await further instructions.

  3. 🔒 Set up credentials

    Currently the API requires an access_token for authentication. Applications request OAuth2 tokens on behalf of users and must declare scopes (public, private, write) based on required permissions; by default apps have public read-only scope, and write access requires contacting Product Hunt at hello@producthunt.com. Send the access_token in requests to https://api.producthunt.com/v2/api/graphql (exact header/parameter name for token not fully specified in provided text).

    To get the appropriate API keys, please visit the original source at api.producthunt.com. If you want to protect your environment secrets in a production environment, look into setting up credentials with dlt.

  4. 🏃‍♀️ Run the pipeline in the Python terminal in Cursor

    python product_hunt_pipeline.py

    If your pipeline runs correctly, you’ll see something like the following:

    Pipeline product_hunt load step completed in 0.26 seconds
1 load package(s) were loaded to destination duckdb and into dataset product_hunt_data
The duckdb destination used duckdb:/product_hunt.duckdb location to store data
Load package 1749667187.541553 is LOADED and contains no failed jobs

  5. 📈 Debug your pipeline and data with the Pipeline Dashboard

    Now that you have a running pipeline, you need to make sure it’s correct, so you do not introduce silent failures like misconfigured pagination or incremental loading errors. By launching the dlt Workspace Pipeline Dashboard, you can see various information about the pipeline to enable you to test it. Here you can see:

    • Pipeline overview: State, load metrics
    • Data’s schema: tables, columns, types, hints
    • You can query the data itself
    dlt pipeline product_hunt_pipeline show

  6. 🐍 Build a Notebook with data explorations and reports

    With the pipeline and data partially validated, you can continue with custom data explorations and reports. To get started, paste the snippet below into a new marimo Notebook and ask your LLM to go from there. Jupyter Notebooks and regular Python scripts are supported as well.

    import dlt

data = dlt.pipeline("product_hunt_pipeline").dataset()
# get ["api/graphql"] table as Pandas frame
data.["api/graphql"].df().head()
