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:
- Sign up at Cohere Dashboard.
- 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:
- Clone the Express Boilerplate from GitHub to your local machine.
- 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:
- Install the necessary dependencies using
yarn
ornpm
. - Start the server by running
yarn dev
ornpm dev
. - 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:
- Create a folder named
routes
in the root of your project. - Add a file named
description.js
within theroutes
folder. - Implement the routing logic in the
description.js
file. - 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:
- Create a folder called
lib
in the root directory. - Add a file named
description-generator.js
in thelib
folder. - 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:
- 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:
- Send a POST request to
localhost:3000/description
with JSON data containing the keys product and keywords.
