pretty-bytes
Convert bytes to a human readable string: 1337 → 1.34 kB
pretty-bytes is a JavaScript utility for converting raw byte counts into compact, human-readable size strings. It uses decimal SI units by default, turning values such as 1337 bytes into 1.34 kB. The library can display bits instead of bytes and can switch to binary prefixes such as KiB when appropriate. Signed output is available for showing positive or negative size differences. Formatting can be localized, and developers can control fractional digits, spacing, and non-breaking spaces. Fixed-width output can align values neatly in tables, status displays, and progress interfaces. The function accepts both regular numbers and BigInt values, making it suitable for a wide range of file-size and data-rate displays. -

pretty-ms
Convert milliseconds to a human readable string
pretty-ms is a JavaScript utility for converting millisecond values into compact, human-readable durations. It accepts both numbers and BigInt values and automatically breaks durations into appropriate time units. Developers can choose concise output, full unit names, or digital-clock-style colon notation. Precision controls determine how seconds and milliseconds are rounded and displayed. The package can expose microseconds and nanoseconds for sub-millisecond values and can represent sub-second durations as decimal seconds. Options also let applications limit the number of displayed units or hide particular duration components. It is useful for timers, benchmarks, progress indicators, logs, and other interfaces that need readable elapsed-time values. -

Crypto Arbitrage
A cryptocurrency arbitrage opportunity calculator
A cryptocurrency arbitrage opportunity calculator and trading bot. Over 800 currencies and 50 markets. In short, it collects JSON from multiple different cryptocurrency markets, goes through the results, and finds the highest and lowest price for each coin. The script will find the highest price (chbtc.com), and lowest price (Bittrex), and divide the two: 51.8/38.23 = ~1.35 (~35% profit margin) and then push these results to the browser. It will also find the next highest market pairs, e.g. chbtc / jubi is the second-highest pair and chbtc/Bittrex the third, jubi/Bittrex the fourth and so on until every possible combination has been computed. Currently you will have to add a market object with the correct settings in the array markets, situated in the settings.js file. I am updating the project every day and this will change soon. You can temporarily stop loading a market from the frontend, or remove the market by deleting the object in settings.js. -
