Introduction

In this article, we will explore how to build a full-stack app that incorporates the power of AI. We will leverage various technologies such as Astro, Solid JS, PocketBase, and Hugging Face Transformers to create a dynamic and feature-rich application. By following the step-by-step guide provided, you will gain insights into setting up the backend service, integrating AI functionalities, and creating a seamless connection between the backend and frontend components of the app.

Building the Backend

Setting up the PocketBase backend service

To start building our app, we first need to set up the PocketBase backend service. Visit the PocketBase website, download the installer, and run the PocketBase serve command. This will expose multiple endpoints for us to use. Navigate to the admin URL and set up a new collection named "posts". Within this collection, we will add three STRING fields: "text" to store the blog post body, "gist" to generate a summary using AI, and "tags" to create a comma-separated list of tags also generated by AI. PocketBase will handle unique IDs and the creation and update audit columns for us.

Configuring the API rules

Once the collection is created, we need to configure the API rules. Grant general access to all REST endpoints associated with the "posts" collection. However, keep in mind that in production environments, it is advisable to grant only the necessary permissions to ensure security. Starting with restrictive access and gradually granting permissions is the recommended approach.

Leveraging the Power of AI

Getting started with Hugging Face Transformers

Now, let's dive into the exciting field of AI. Hugging Face Transformers will be our tool of choice to work with powerful pre-trained models. Visit the Hugging Face website and follow the setup steps. Additionally, install FastAPI in your Python project.

Installing FastAPI and setting up the AI functionalities

In just 25 lines of code, we can incorporate all the AI functionality we need. The sentiment analysis task will help determine if a post comment is positive or negative. The summarization task will provide a gist of our blog post, and the zero-shot pipeline task will generate Relevant tags. Each pipeline can use different models, and a wide range of models can be found on the Hugging Face website. By calling these pipelines, we can utilize powerful AI capabilities effortlessly. The data will be analyzed, tokenized, and converted into the expected format through post-processing.

Integrating the Backend and Frontend

Building the Astro frontend

Astro, combined with Solid JS, will be used to build the frontend of our app. Astro's file system-based routing and server-side rendering capabilities make it an excellent choice. Under the "pages" directory, create an "index.astro" file to define the template and styling for the home page. In the template, add HTML elements for the presentation and use code fences to retrieve the most recent post from our PocketBase backend.

Creating the Astro pages for displaying articles

To display articles in detail, we need to create Astro pages. Under the "pages" directory, create a new folder named "read" and add a dynamic routing Astro page. Utilize the Astro params to grab the ID passed as a path variable and fetch the corresponding entry from the database. The layout of the page should be straightforward. Note that since we are using dynamic routing, Astro will not be able to statically generate the entire app at build time, so we need to adjust the output approach to server-side rendering.

Conclusion

In conclusion, building complex apps that incorporate AI has become relatively easy with the advancements in technology. By utilizing the power of tools like Astro, Solid JS, PocketBase, and Hugging Face Transformers, developers can create dynamic and AI-driven applications. This article has provided an overview and step-by-step guide to building the backend, leveraging AI, and integrating the backend and frontend components. Stay curious and continue exploring the possibilities of AI in your programming endeavors.
