Journey's End: Mastering Cohere for Product Descriptions

Welcome to the end of our tutorial series on using Cohere for product descriptions! By now, you should have successfully constructed a product description generator API leveraging Cohere's powerful capabilities. This guide is tailored for individuals with a foundational understanding of JavaScript and Node.js. If you're just starting, please explore some introductory resources to get comfortable with the basics before diving in.

Overview of the Cohere Tool

Cohere is a robust language model that can generate high-quality textual content based on your prompts. We will specifically employ the xlarge model for our product descriptions. This model excels in producing engaging and coherent text suitable for various applications.

Getting Your Cohere API Key

To access the API, you first need to acquire your API key. Follow these simple steps:

  1. Sign up at Cohere Dashboard.
  2. Once you've successfully signed up, locate your API key on the main screen or in the settings section.

Setting Up Your Project

To simplify the coding process, we’ll use an Express boilerplate. Follow the instructions below:

  1. Clone the Express Boilerplate from GitHub to your local machine.
  2. Make sure the repository is added to your own repositories for easy access.

Running the Project Locally

Now, it’s time to run your project:

  1. Install the necessary dependencies using yarn or npm.
  2. Start the server by running yarn dev or npm dev.
  3. Create a .env file in the project’s root directory and add your API key to it in the format: COHERE_API_KEY={YOUR_API_KEY}.

Creating Routing for the API

Next, we will set up our routing structure:

  1. Create a folder named routes in the root of your project.
  2. Add a file named description.js within the routes folder.
  3. Implement the routing logic in the description.js file.
  4. Update the index.js file to include the new route:
    • Import the description route: const description = require("./routes/description.js");
    • Add the route: app.use("/", description);

Creating the Generator Function

To generate descriptions, you need to set up the generator function:

  1. Create a folder called lib in the root directory.
  2. Add a file named description-generator.js in the lib folder.
  3. Implement the code for the generator function in this file.

Integrating the Generator Function in the POST Route

You need to modify your description.js to utilize the generator function. Update it with the following information:

  1. Adapt the code in description.js to call the generator function when processing a POST request.

Now that everything is set up, you can run your project locally. Use tools like Postman or Insomnia to test your API.

Testing the API

To test your product description generator API:

  1. Send a POST request to localhost:3000/description with JSON data containing the keys product and keywords.
