tinystring

A tiny wrapper around std::stringstream.

Installation

npm install tinystring

Example

var TinyString = require('tinystring');
 
var str = new TinyString();
 
str.append('one');
str.append('two');
str.append('three');
 
console.log(str.value());
// onetwothree

Performance

The goal is to minimize the memory usage when building up huge strings. In most cases using a stream is a better design, but this is for cases where that might not be possible.

var base = 'This is a test string';
 
var str = '';
 
for (var i = 0; i < 8000000; ++i) {
  str += (i + ' : ' + base);
}
