Install Dependencies

Install the required packages for your project:

Create Configuration File

Create a vue.config.js file in your project root:

module.exports = {
  publicPath: "/",
  outputDir: "dist",
  assetsDir: "static",
};

Update Package.json

Add scripts to your package.json:

{
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview"
  }
}

Start Development Server

Run the development server:

Create Component File

Create a new file MyButton.vue in your components directory.

Add Template

Define your component's structure:

<template>
  <button class="btn">Click me</button>
</template>

Add Script Setup

Add your component logic:

<script setup lang="ts">
  const handleClick = () => {
    console.log("Button clicked!");
  };
</script>

Add Styles

    cursor: pointer;
  }

  .btn:hover {
    background: #35495e;

Project Setup

Initialize a new project:

Navigate to the project:

cd my-project

Install Additional Packages

  content: [
    "./index.html",
    "./src/**/*.{vue,js,ts,jsx,tsx}",
    "./node_modules/@ui-thing/**/*.{vue,js,ts,jsx,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
};

Backup Your Project

Before making changes, create a backup:

git add .
git commit -m "Backup before v2 migration"
git branch backup-v1

Update Dependencies

Update to the latest versions:

Change old import syntax:

// Before

// After
import { UiButton } from "ui-thing/components";
import { Button } from "ui-thing/v1";

Update Props

Several components have renamed props:

Test Your Application

Run your test suite:

Fix any failing tests based on the new API.

Update Styles

Some class names have changed:

- <UiButton class="btn-primary">
+ <UiButton appearance="primary">

Deploy

Once everything is working, deploy your updated application:

Deploy to your hosting provider

Install Server Framework

Install Express and required middleware:

Create Server File

Create server.js:

import cors from "cors";
import dotenv from "dotenv";
import express from "express";

dotenv.config();

const app = express();
const PORT = process.env.PORT || 3000;

app.use(cors());
app.use(express.json());

app.get("/api/health", (req, res) => {
  res.json({ status: "ok" });
});

app.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`);
});

Configure Environment

Create .env file:

PORT=3000
DATABASE_URL=postgresql://localhost:5432/mydb
JWT_SECRET=your-secret-key

Add Database

Install Prisma for database management:

Initialize Prisma

Set up your database schema:

Create Schema

Define your data models in prisma/schema.prisma:

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

model User {
  id        Int      @id @default(autoincrement())
  email     String   @unique
  name      String?
  createdAt DateTime @default(now())
}

Run Migrations

Create and apply database migrations:

Start Server

Run your API server:

Understanding Components

Components are reusable pieces of UI. They can contain:

1. Template - The HTML structure
2. Script - The component logic
3. Style - The component styling

Component Communication

Components communicate through

Best Practices

Identify the Issue

First, gather information about the problem:

• What error message do you see?
• When did the issue start?
• What were you doing when it occurred?
• Can you reproduce it consistently?

Check the Console

Open browser DevTools (F12) and look for:

Review Recent Changes

Use git to check recent modifications:

git log --oneline -10
git diff HEAD~1

Search Documentation

Check if this is a known issue:

1. Search the official docs
2. Check GitHub issues
3. Look for related discussions
4. Review the changelog

Try Basic Solutions

Common fixes:

Ask for Help

If you're still stuck, ask for help with:

• A clear description of the problem
• Steps to reproduce
• Your environment details (OS, Node version, etc.)
• Relevant code snippets
• Error messages and stack traces
