## Astro.js Image Component

When I built [my linktree](https://links.shramko.dev/) website I forgot to use [Image component](https://docs.astro.build/en/guides/images/) in
Astro.js.<br></br>I used the `img` tag instead. So after learning about the Image component in Astro.js, I decided to
add it.

```tsx
<Image
  src={UserProfileImage}
  densities={[1, 2]}
  width="160"
  height="160"
  quality="max"
  alt="Serhii Shramko is eating pizza."
/>
```

And what do you think? It's works locally, but when I deployed it on Vercel, I got an error.

<Image src="astro-image-error.png" alt="Astro Image doesn't work on Vercel" />

## How to Fix the Error

Searching... 🔎

Powerful ChatGPT?<br></br>
No, I found the solution on old and good [GitHub](https://github.com/withastro/astro/issues/5253).<br></br>
And a little bit of [documentation](https://docs.astro.build/en/reference/errors/missing-sharp/).

```javascript:astro.config.mjs
// Update astro.config.mjs with image service

export default defineConfig({
  image: {
    service: sharpImageService(),
  }
});
```

```bash
// Install sharp package
pnpm add sharp
```

Done and deployed. Now it works perfectly on Vercel.

<Image src="linktree.jpeg" alt="My linktree" priority />

**1 hour** of work and I have my own link tree website with Astro.js and Vercel on my own subdomain.

Check out the final result: [links.shramko.dev](https://links.shramko.dev/)

## Why Astro.js?

I [wrote about Astro.js](/blog/astro), and I was impressed by its performance and ease of use.
<abbr title='In my humble opinion'>IMHO</abbr>, Astro one of the most promising and fast-growing static site generators out there.

## Setting Up the Project

I started by creating a new Astro project:

```bash
pnpm create astro@latest
```

You can read small article about why I use [pnpm](/blog/pnpm) 🤘.

## Data for the Link Tree

First of all I created a data file with my links. I used a simple JSON structure:

```json:data/user.json
{
  "name": "Serhii Shramko",
  "profession": "Senior Software Engineer",
  "links": [
    {
      "url": "https://shramko.dev/",
      "icon": "url",
      "title": "Personal Portfolio",
      "description": "All my latest news and blog posts"
    },
    {
      "url": "https://github.com/Shramkoweb",
      "icon": "github",
      "title": "Github Profile",
      "description": "My Github"
    }
  ]
}
```

This approach allows me to easily add, remove, or update links without changing the HTML structure.

## Layout and File Structure

Astro.js allow use simple file structure. And for this project I don't need complex structure. I created an index page:

```jsx:pages/index.astro
---
import Layout from '../layouts/Layout.astro';
import Profile from '../components/Profile.astro';
import List from '../components/List.astro';
// Simple component that renders the main layout, the profile, and the list of links.
---

<Layout title="Link tree | Serhii Shramko">
    <main class="container" id="container">
        <Profile />
        <List />
    </main>
</Layout>
```

```jsx:components/Link.astro
---
import Instagram from "./icons/instagram.astro";
import Linkedin from "./icons/linkedin.astro";
import Url from "./icons/url.astro";
import Youtube from "./icons/youtube.astro";
import Pdf from "./icons/pdf.astro";
import Github from "./icons/github.astro";

interface Props {
    icon: string;
    title: string;
    description: string;
    url: string;
}

const { icon, title, description, url } = Astro.props;
---

<a href={url} class="link" target="_blank">
    <span class="link__icon">
        {icon === 'instagram' && <Instagram />}
        {icon === 'linkedin' && <Linkedin />}
        {icon === 'url' && <Url />}
        {icon === 'youtube' && <Youtube />}
        {icon === 'github' && <Github />}
        {icon === 'pdf' && <Pdf />}
    </span>

    <div class="link__content">
        <h2 class="link__title">{title}</h2>
        <p class="link__description">{description}</p>
    </div>
</a>
```

Astro.js allows you to create components from svg code. I created a separate component for each icon:

```jsx:components/icons/github.astro
<svg xmlns="http://www.w3.org/2000/svg" width="800" height="800" viewBox="0 0 20 20"></svg>
```

## Analytics

Almost done. Just add Vercel Analytics to the project.

<Image src="astro-analytics.jpg" alt="Analytics on vercel" />

```bash
pnpm add @astrojs/vercel
pnpm add @vercel/analytics
```

```js:astro.config.mjs
import { defineConfig } from 'astro/config';
import vercel from '@astrojs/vercel/serverless';

// https://astro.build/config
export default defineConfig({
    output: 'server',
    adapter: vercel({
        webAnalytics: { enabled: true }
    }),
});
```

## Deploying to Vercel

[Vercel makes deploying](https://vercel.com/docs/frameworks/astro) Astro projects a breeze. Here's how I did it:

1. I pushed my project to a GitHub repository.
2. I connected my Vercel account to my GitHub account.
3. In the Vercel dashboard, I clicked "New Project" and selected my link tree repository.
4. Vercel automatically detected that it was an Astro project and suggested the correct build settings.
5. I clicked "Deploy" and waited for the magic to happen!

## Custom Domain with Vercel Subdomains

<Image src="vercel-domain.jpg" alt="Domain on vercel" />


To use my custom domain with Vercel, I followed these steps:

1. In the Vercel project settings, I navigated to the "Domains" section.
2. I added my custom domain: `links.shramko.dev`.
3. Done! Vercel automatically set up the necessary DNS records for me.

## Conclusion

Building a link tree with Astro.js and deploying it on Vercel was a smooth and enjoyable process. I spent no more than
an hour and got a fast, efficient, and visually appealing website that and try new technologies.

Sounds great, right? 🌲

## Introduction

<Image src="pnpm-logo.png" alt="pnpm logo on gay background" />

I found article from Vercel
about [Projects using pnpm can now be deployed with zero configuration](https://vercel.com/changelog/projects-using-pnpm-can-now-be-deployed-with-zero-configuration)
and I wanted to try it.

## Why Migrate to pnpm?

Before diving into the migration process, it’s important to understand why pnpm is beneficial:

1. **Speed** 🚀: pnpm installs dependencies faster than npm by using a unique package linking mechanism.
2. **Disk Space** 🔎: It saves disk space by using a global store and hard links.
3. **Consistency** 💡: pnpm ensures that dependencies are installed in a way that is more consistent with the version
   specified in your `package.json`.

## Installation of pnpm

First, you need to install pnpm globally. You can do this by running:

```bash
brew install pnpm
```

## Migration Steps

### 1. Clean the Project

Remove the `node_modules` directory and the `package-lock.json` file. This step is crucial to ensure that there are no
leftover artifacts from npm that might interfere with pnpm.

```bash
rm -rf node_modules package-lock.json
```

### 2. Initialize pnpm

Run the following command to initialize pnpm in your project directory:

```bash
pnpm install
```

This command will create a `pnpm-lock.yaml` file and install all the dependencies listed in your `package.json`.

### 3. Verify Dependency Installation

Check that all dependencies have been installed correctly by running:

```bash
pnpm list
```

This command lists all the installed dependencies and their versions. Make sure that there are no missing or outdated
packages.

<Image src="pnpm-list.png" alt="pnpm list command result in terminal" />

## Updating Scripts

### 1. Update npm Scripts

In your `package.json`, update any npm scripts to use pnpm where necessary. For example, if you have a script for
installing dependencies, change it from:

```json
"scripts": {
"install": "npm install"
}
```

to:

```json
"scripts": {
"install": "pnpm install"
}
```

### 2. Update CI/CD Pipelines

If your project uses CI/CD pipelines, ensure that the build scripts and installation commands are updated to use pnpm.
For example, in a [GitHub Actions  with pnpm](https://pnpm.io/continuous-integration) workflow, you might update the
step as follows:

```yaml
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: pnpm/action-setup@v4
        with:
          version: 9
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ matrix.node-version }}
          cache: 'pnpm'
      - name: Install
        run: pnpm i
      - name: Run Tests // All your CI commands
        run: pnpm run test
```

## Handling Issues and Troubleshooting

During the migration, you might encounter some issues.

> Error: Unable to locate executable file: pnpm. Please verify either the file path exists or the file can be found
> within a directory specified by the PATH environment variable. Also check the file mode to verify the file is
> executable.

I stuck with this error when I tried to run the `pnpm` command in GitHub Actions.

The solution was to use the `pnpm/action-setup@v4` before `actions/setup-node@v4`.
So simply just copy the [above code](#2-update-cicd-pipelines) and paste it in your `.yml` file.

## Conclusion

This migration helped me to reduce the time of deployment by **44%** and the size of `node_modules` by **5%**.

## 🚀 Deploy

Each commit triggers a build and environment (Production | Preview) creation.
And then we start multiple steps:

> I have post about [ESLint with TypeScript](/blog/eslint-with-typescript) 

- ESLint & TypeScript: Linting the project for simple mistakes and Type checking
- Checkly: Running end-to-end tests
- Vercel: Building and deploy website to production and other environments

Once ESLint, TypeScript, Checkly, and the Build all successfully complete, then we can deploy site.

<Image src="deploy.jpeg" alt="Deploy process screenshot on Vercel"/>

## MDX Compilation

`mdx-bundler` & `next-mdx-remote` allows you to extend [remark](https://github.com/remarkjs/remark)
and [rehype](https://github.com/rehypejs/rehype), providing external plugins to hook into the compilation process.

It helps me to convert a link to an external link and one for wrapping images
with [Next Image](https://nextjs.org/docs/pages/api-reference/components/image).

How does it look:

```tsx
import { serialize } from 'next-mdx-remote/serialize';
import remarkGfm from 'remark-gfm';
import rehypeSlug from 'rehype-slug';
import rehypeCodeTitles from 'rehype-code-titles';
import rehypeAutolinkHeadings from 'rehype-autolink-headings';
import rehypePrism from 'rehype-prism-plus';

export const compileMDX = async (content: string) => serialize(content, {
  mdxOptions: {
    remarkPlugins: [remarkGfm],
    rehypePlugins: [
      rehypeSlug,
      rehypeCodeTitles,
      rehypePrism,
      [
        rehypeAutolinkHeadings,
        {
          properties: {
            className: ['anchor'],
          },
        },
      ],
    ],
    format: 'mdx',
  },
});
```

```tsx
import { MDXComponents } from '@/components/mdx-components';

<div className="w-full mt-4 prose dark:prose-dark max-w-none">
  <MDXRemote {...content} components={MDXComponents} />
</div>
```

## Monitoring with Sentry

Monitoring is an essential part of development.
It’s usually one of the first things you’d want to do after setting up an existing project or getting started with a new
one. Without monitoring, it will be challenging to detect issues in your application or how to resolve them.

> There example of some kind of ["dispatch table" pattern](/blog/dispatch-tables).

```tsx
const { withSentryConfig } = require("@sentry/nextjs");

/** @type {import("next").NextConfig} */
const nextConfig = {
  swcMinify: true,
  experimental: {
    images: {
      allowFutureImage: true,
    },
    browsersListForSwc: true,
    legacyBrowsers: false,
  },
  poweredByHeader: false,
  reactStrictMode: true,
};

// dispatch table pattern
const nextConfigByEnv = {
  production: withSentryConfig(nextConfig, {
    silent: true
  }),
  development: nextConfig
}

module.exports = nextConfigByEnv[process.env.NODE_ENV];
```

## Database and Prisma

[Prisma](https://www.prisma.io/nextjs) makes database access easy. With auto-generated and type-safe queries based on
your database schema, it's easier than ever to manage your data.
Whether you have an existing database or you're starting from scratch, Prisma has you covered.

When combining Prisma with Next.js, you can skip the [CRUD](https://www.codecademy.com/article/what-is-crud) boilerplate
and directly query the database.
Less code means less bugs.

### Heroku Postgres

Heroku Postgres gives me all the benefits of PostgreSQL without having to spin up and maintain the databases ourselves.
And it is [easy integrate with PhpStorm](https://www.jetbrains.com/help/phpstorm/how-to-connect-to-heroku-postgres.html)
.

### Type Safety

```sql
model
User {
  id       String  @id @default(cuid())
  email    String  @unique
  password String
  name     String?
}
```

```typescript
type User = {
  id: string
  email: string
  password: string
  name: string | null
}
```

### Querying Data

```typescript
const views = await prisma.views.upsert({
  where: { slug },
  create: {
    slug,
  },
  update: {
    count: {
      increment: 1,
    },
  },
});
```

## Testing

As a developer, you know how important tests are for any production-level project.
Writing tests takes some time, but they will help you in the long run to solve problems in the codebase.

I also [integrate these tests](https://github.com/Shramkoweb/Portfolio/blob/develop/.github/workflows/tests.yml) into
GitHub Actions, so that whenever I deploy to production or make a pull request, tests will run automatically.

## Next.js

Next's framework allows you to build scalable, performant React code without the configuration hassle.

Quick list of why Next.js has been so good for me:

- Zero Config: Automatic compilation and bundling. Optimized for production from the start
- SSG and SSR: It allows you to render your content in different ways, depending on your application's use case. These
  include pre-rendering with Server-side Rendering or Static Generation, and updating or creating content at runtime
  with Incremental Static Regeneration
- Deploy: You can deploy in a few clicks to [Vercel](https://vercel.com)
- SEO: Automatic Static Optimization & Head Component
- React ecosystem: Wide range of tools and npm packages
- Out of the box support: Through webpack, Next provides developers with out-of-the-box support for asset compilation,
  hot reloading and code splitting, which can further speed up development

## Conclusion

I can't tell you how much I've learned building this website. 🤓

I'm excited about the new design. And I just had fun doing it. I hope you enjoy it too!

The project is developing and still has many unimplemented features, you can see or suggest
them [here](https://github.com/Shramkoweb/Portfolio/issues).
