🔥Pulstack: Deploy your static site to S3 or GitHub in <1 min🙂
- Pulstack is a CLI tool that allows deploying static websites to either AWS S3 + CloudFront or GitHub Pages using the Pulumi Automation API.
- With one command, users can transform a folder of static files into a live website in under a minute, without needing to write code or manually interact with GitHub.
- The tool works in a 2-step flow, with specific commands for GitHub Pages and AWS S3 + CloudFront deployments.
- Pulstack leverages Pulumi's Automation API to manage stacks, configurations, and resources in code form instead of YAML.
- It provides live demo links to showcase deployments on AWS (S3 + CloudFront) and GitHub Pages, along with the GitHub repository created through Pulumi Automation.
- The CLI tool features clean prompts for setup, supports one-command destroy for quick stack termination, and ensures secure AWS deployments by following best practices.
- Before using Pulstack, users need to have Node.js, Pulumi, and AWS CLI installed and configured properly.
- The project incorporates modules like index.js for CLI setup, init.js for project initialization, pulumiProgram.js for infra as code setup, deploy.js for AWS deployment, and deployGithub.js for GitHub Pages deployment.
- Challenges faced during development included dealing with the GitHub Pages requirement for the gh-pages branch to exist before enabling it and managing GitHub access token permissions.
- Through this project, the developer learned the power of Pulumi for defining infrastructure as code, realized the benefits of automation, and plans to expand support to Azure and GCP in the future.
- The project integrated Pulumi for AWS deployment, automating S3 bucket creation, CloudFront setup, and GitHub repository management, offering users a seamless deployment process.

Angular Facade Pattern: So I Can Even Understand
- The Facade Pattern in Angular helps in managing state and keeping projects clean, organized, and easier to work with over time.
- A typical Facade Pattern consists of a service responsible for managing data and fetching it from an API, a facade service that simplifies interaction between components and the underlying service, and clean components that only interact with the facade.
- Jasmine, a popular testing framework for Angular, can be used for unit testing the facade to ensure proper delegation of calls and functionality.
- However, the introduction of a facade layer in small applications may unnecessarily complicate the architecture, and the pattern can make debugging harder due to hidden implementation details.
