مضغط JavaScript - ضغط الكود
العودة للأدواتمضغط JavaScript المهني ومحسن الكود
أداة ضغط JavaScript متقدمة للمطورين ومهندسي DevOps. قلل أحجام الحزم بنسبة تصل إلى 85% مع الحفاظ على الوظائف الكاملة.
ضغط AST المتقدم مع إزالة الكود الميت
تشويش أسماء المتغيرات وتحسين الدوال
دعم ES6+/ES2020+ مع تجميع الوحدات
Tree shaking and unused code removal
Source map generation for debugging production code
Batch processing for multiple files and entire projects
Practical Examples
تحسين مكون React
تقليل حجم حزمة React بنسبة 70%
BEFORE (Original JavaScript)
const App = () => { return <div>Hello</div>; };
AFTER (Minified JavaScript)
const a=()=>React.createElement("div",null,"Hello");
Express.js API Route Compression
Compress Node.js API routes for optimized server deployment
BEFORE (Original JavaScript)
const express = require("express");
const bcrypt = require("bcrypt");
const jwt = require("jsonwebtoken");
const { validationResult } = require("express-validator");
const router = express.Router();
// User authentication endpoint
router.post("/login", async (req, res) => {
try {
// Validate input
const errors = validationResult(req);
if (!errors.isEmpty()) {
return res.status(400).json({
success: false,
message: "Validation failed",
errors: errors.array()
});
}
const { email, password } = req.body;
// Find user in database
const user = await User.findOne({ email });
if (!user) {
return res.status(401).json({
success: false,
message: "Invalid credentials"
});
}
// Verify password
const isValidPassword = await bcrypt.compare(password, user.password);
if (!isValidPassword) {
return res.status(401).json({
success: false,
message: "Invalid credentials"
});
}
// Generate JWT token
const token = jwt.sign(
{ userId: user._id, email: user.email },
process.env.JWT_SECRET,
{ expiresIn: "24h" }
);
res.json({
success: true,
message: "Login successful",
token,
user: {
id: user._id,
email: user.email,
name: user.name
}
});
} catch (error) {
console.error("Login error:", error);
res.status(500).json({
success: false,
message: "Internal server error"
});
}
});
AFTER (Minified JavaScript)
const e=require("express"),r=require("bcrypt"),s=require("jsonwebtoken"),{validationResult:t}=require("express-validator"),a=e.Router();a.post("/login",(async(e,a)=>{try{const o=t(e);if(!o.isEmpty())return a.status(400).json({success:!1,message:"Validation failed",errors:o.array()});const{email:n,password:i}=e.body,c=await User.findOne({email:n});if(!c)return a.status(401).json({success:!1,message:"Invalid credentials"});if(!await r.compare(i,c.password))return a.status(401).json({success:!1,message:"Invalid credentials"});const u=s.sign({userId:c._id,email:c.email},process.env.JWT_SECRET,{expiresIn:"24h"});a.json({success:!0,message:"Login successful",token:u,user:{id:c._id,email:c.email,name:c.name}})}catch(e){console.error("Login error:",e),a.status(500).json({success:!1,message:"Internal server error"})}}));

Troubleshooting Guide
Syntax Errors After Minification
Check for ES6+ features in legacy environments or missing semicolons
Broken Functionality
Disable variable mangling for libraries that depend on function names
Source Map Issues
Ensure proper source map configuration and file paths
Large File Processing
Split large files into smaller chunks or use streaming processing
Third-party Integration
Use exclude patterns for external libraries that should not be minified
