fastfile

fastfile is a package to read/write binary files with a transparent cache.

This library maintains a read and write cache that allows to write asynchronously
improving the speed of the reads and writes of big files.

Usage

``npm install fastfile`

`javascript

const fastFile = require("fastfile");

async function writeFile() { const f = await fastFile.createOverride("pattern.bin");

const buff = Buffer.from("0001020304050607", "hex"); for (let i=0; i<1000; i++) { await f.write(buff, i*8); }

await f.close(); }

async function readFile() { const f = await fastFile.readExisting("pattern.bin");

const buff = await f.read(16, 8);

await f.close();

return buff;

}

writeFile().then( () => { readFile().then( (buff) => { console.log(buff.toString("hex")); }); });
