string-compressor-frontend (ttt)

The Algorithm

• The current algorithm being used here is a simple algorithm that makes use of the vast range of unicode characters to compress the size of the string
• The compressed string is a string that is replaced by a specific unicode character for each possible pairing of alphabets, thus reducing string size by upto half the original size.
• For Decompression, the reverse of the algorithm is implemented. Thus the each unicode character of the string will be inflated using the respective original character pairing.

Components Of The Code

Backend (NodeJS deployed on Heroku)

• Routes for "/" for information to use the API, "/compress/ExampleString" to compress a string called ExampleString and "/decompress/ExampleString" to decompress an example string
• A compression function compress(str) that performs the above algorithm for compression by iterating through the input string str
• A decompression function decompress(str)that performs the above algorithm for decompression by iterating through the input string str
• The API returns an object which contains "str" as the input string, "compressed_str" in the case of compression, and "decompressed_str" in the case of decompression.

Frontend (React deployed on Heroku)

• Function GetCompressed(e) that extracts decompressed_str from the JSON object that is returned by the API
• Function GetDecompressed(e) that extracts decompressed_str from the JSON object that is returned by the API
• Both these function display the result on an h3 tag below when the compress / decompress buttons are clicked

libraries and plugins used
