Often in the life of a web developer, you need to make a grid, but the limitations of the browser (Internet Explorer 😭)
do not allow you to use, for example, [CSS Grid](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout).

This is
where [CSS Flexbox](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox)
comes to the rescue. He is our friend, brother and helper. 🫡

This post is about how to create a flexbox-based grid component in React. The component should be reusable and painless
to configure.

## Preparation

Many of those who created components in React are familiar with
the [classnames](https://www.npmjs.com/package/classnames) library, but I want to recommend you the
[clsx](https://www.npmjs.com/package/clsx) library, which is smaller and similar in functionality.

It is not necessary for our component, but it is more comfortable with them:

```shell
npm i clsx
```

## Step 1: Create React component architecture

```jsx
const Grid = ({ children }) => (
  <div className='grid'>
    {children}
  </div>
);
```

```jsx
const GridColumn = ({ children }) => (
  <div className='grid__col'>
    {children}
  </div>
);
```

```jsx
const GridRow = ({ children }) => (
  <div className='grid__row'>
    {children}
  </div>
);
```

## Step 2: Create styles with SCSS

I use the [BEM](https://en.bem.info/methodology/) methodology for styles, as I think it is excellent for component
libraries.

```scss
// Base styles
.grid {
  width: 100%;

  &__row {
    display: flex;
    flex-wrap: wrap;
  }

  &__col {
    flex-grow: 1;
    flex-shrink: 0;

    // For decoration only
    background-color: #bbeffd;
    border: 1px solid #61dafb;
    padding: 15px;
    text-align: center;
    margin-bottom: 25px;
  }
}
```

What about columns logic?

```scss
.grid__row--col-3 > .grid__col {
  width: 33%;
}

.grid__row--col-2 > .grid__col {
  width: 50%;
}
```

It is so ugly. Why we need to do it manually?

Let's try some [Sass](https://sass-lang.com/documentation/at-rules/control/each) magic 🪄?

```scss
$columnsNumberToWidth: (
  2: 50%,
  3: 33%,
  4: 25%,
  5: 20%,
  6: 16.6%,
);

@each $number, $width in $columnsNumberToWidth {
  .grid__row--col-#{$number} > .grid__col {
    width: $width;
  }
}
```

You can see how SASS code is transformed into CSS [here](https://www.sassmeister.com/):

<Image src="sass.jpeg" alt="sassmeister site screenshot" />

## Step 3: Add logic to the GridRow component.

```jsx
import clsx from 'clsx';

const GridRow = (pops) => {
  const {
    children,
    columns,
  } = props;

  const rootClasses = clsx('grid__row', {
    [`grid__row--col-${columns}`]: columns,
  });

  return (
    <div className={rootClasses}>
      {children}
    </div>
  );
};
```

## Let's check result

```jsx
<Grid>
  <GridRow columns={6}>
    <GridColumn>1 of 6</GridColumn>
    <GridColumn>2 of 6</GridColumn>
    <GridColumn>3 of 6</GridColumn>
  </GridRow>

  <GridRow columns={6}>
    <GridColumn>1 of 6</GridColumn>
    <GridColumn>2 of 6</GridColumn>
    <GridColumn>3 of 6</GridColumn>
    <GridColumn>4 of 6</GridColumn>
    <GridColumn>5 of 6</GridColumn>
    <GridColumn>6 of 6</GridColumn>
  </GridRow>

  {/* ...  */}
</Grid>
```

## Recap

Writing components has an endless process ♾.

Next, you can add a dynamic size of each column, column gaps, change the component tag type, breakpoints and so on...

## 🍭 The new look

Here's how the [latest design](https://shramkoweb.github.io/homepage/) looked before I updated it.

This is a simple <abbr title="HyperText Markup Language">HTML</abbr> and <abbr title="Cascading Style Sheets,">
CSS</abbr> site.
No <abbr title="JavaScript">JS</abbr> and frameworks 😂.

## 🚀 Deploy

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

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

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/api-reference/next/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.
t’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.

```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,
};

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.

In my company, we use it for [CleanMyMac JP](https://cleanmymac.jp/).

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).
