#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?
View fs-read.js
var fs = require('fs');
var CHUNK_SIZE = 4 * 1024;
var buffer = new Buffer(CHUNK_SIZE);
var filePath = __dirname + '/public/index.html';
// fs.open(filePath, 'r', function(err, fd) {
// if (err) throw err;
//
// fs.read(fd, buffer, 0, CHUNK_SIZE, null, function(err, nread) {
// if (err) throw err;
You can’t perform that action at this time.
