Introduction to LZ-String

LZ-String is a powerful JavaScript library that offers efficient string compression and decompression functionalities. It’s highly useful for reducing the size of the data transmitted and stored. In this article, we will explore various APIs provided by LZ-String with practical examples and discuss their applications in a sample app.

API Explanations and Code Snippets

1. Compress a String

The compress method compresses a given string. This can be used to reduce the size of data before storage or transmission.

  
  const compressed = LZString.compress("This is a sample string to compress.");
  console.log(compressed);
  

2. Decompress a String

The decompress method decompresses a previously compressed string.

  
  const decompressed = LZString.decompress(compressed);
  console.log(decompressed);
  

3. Compress to Base64

The compressToBase64 method compresses a string and encodes it in Base64 format, which is particularly useful for transmitting data in URLs or via email.

  
  const compressedBase64 = LZString.compressToBase64("Data to be compressed and encoded in Base64.");
  console.log(compressedBase64);
  

4. Decompress from Base64

The decompressFromBase64 method decodes a Base64 encoded string and then decompresses it.

  
  const decompressedBase64 = LZString.decompressFromBase64(compressedBase64);
  console.log(decompressedBase64);
  

5. Compress to UTF-16

The compressToUTF16 method compresses a string and encodes it in a UTF-16 format.

  
  const compressedUTF16 = LZString.compressToUTF16("UTF-16 compression example.");
  console.log(compressedUTF16);
  

6. Decompress from UTF-16

The decompressFromUTF16 method decodes a UTF-16 encoded string and then decompresses it.

  
  const decompressedUTF16 = LZString.decompressFromUTF16(compressedUTF16);
  console.log(decompressedUTF16);
  

Sample App Example

Let’s build a simple example application that leverages the compression and decompression APIs of LZ-String. This app will allow users to input text, compress it, and then decompress it.

  
  
  
  
    
  
  
    
LZ-String Compression App
    

    Compress Text
    Decompress Text
    
Compressed Text: 
    
Decompressed Text: 

    
    
  
  
  

By following the steps and examples provided, you can efficiently implement LZ-String in your own applications to manage string compression and decompression.
