Summary: Based on Huffman's trees we can encode pieces of text into their binary traversal paths rather than their character codes. This requires a tree customised for the text to be compressed, as well as a binary string to traverse said tree. The aim of this project is to encode both the tree and the text to enable sending of a single file that can be interpreted to construct the tree and generate the decoded output.
Structure of a file:
Development:
With the command npm run dev you can start listening to file changes and run automated tests against all changes made. Tests are in the test folder and are named to match the file they are testing, with .test infixed between the file name and extension.
All changes are also linted with to Standard JS, and linting and tests must pass to allow commits.
List filesizes:
ls -lhSr
Ty it out, create a copy:
cp readme.md copied-readme
Compress the copy:
node index.js copied-readme
Remove the uncompressed copy:
rm copied-readme
Decompress the compressed file:
node index.js copied-readme.jzip
Compare the outputs:
diff <(cat copied-readme) <(cat readme.md)
