💡 PERFORMANCE TIPS:

Minify JSON before sending over networks to reduce bandwidth
Use minified JSON for production, pretty-printed for development
Combine with GZIP compression for maximum size reduction
Always validate JSON before and after minification

MINIFICATION EXAMPLE:

Original JSON:

{
    "name": "John Doe",
    "age": 30,
    "city": "New York",
    "hobbies": ["reading", "coding", "gaming"]
}

                                    └── theme-colors.json (1.8KB → 1.3KB)

                                    Total: 12.5KB → 9.1KB (27% reduction)

Batch Minification Script:

                                    const fs = require('fs');

                                    const path = require('path');

                                    // Minify all JSON files in configs directory

                                    fs.readdirSync('configs').forEach(file => {

                                      if (file.endsWith('.json')) {

                                        const content = fs.readFileSync(`configs/${file}`);

                                        const minified = JSON.stringify(JSON.parse(content));

                                        fs.writeFileSync(`dist/${file}`, minified);

Common questions and solutions

❓ FREQUENTLY ASKED QUESTIONS

Q: Does minification change my JSON data?

A: NO! Minification only removes unnecessary whitespace (spaces, tabs, newlines). All data values, structure, and formatting within strings remain exactly the same.

Q: When should I NOT minify JSON?

A: Don't minify during development (harder to debug), configuration files that humans edit frequently, or when the JSON size is already very small (under 1KB).

Q: What's the difference between minification and compression?

A: Minification removes whitespace from the source. Compression (like GZIP) uses algorithms to reduce file size further. Use both for maximum performance!
