[SOLVED] Is there a way to compress a long string to a smaller one and vise versa by code?

Is there a way to compress a long string to a smaller one and vise versa by code?

I am working on a plugin for an existing web-based tool in JavaScript. We are collecting data and store it in a string like this: "2.545,3.552,8.568;2.553,9.898,6.542;..." and so on.

The problem is, that we reach an export limit of 64k characters too fast. I wanted to ask - and excuse me if it is a dumb question - if someone knows of an algorithm or method we could use to compress the string before we export it. I am sure that it is technically possible but it certainly exceeds my skills as a programmer.

Thanks for any tips, link or suggestion.

Solution

lz-string looks like it will work.

var string = "2.545,3.552,8.568;2.553,9.898,6.542";
alert("Size of sample is: " + string.length);
var compressed = LZString.compress(string);
alert("Size of compressed sample is: " + compressed.length);
string = LZString.decompress(compressed);
alert("Sample is: " + string);
