Node.js core does its best to treat every platform equally. Even if most Node developers use OS X day to day, some use Windows, and most everyone deploys to Linux or Solaris. So it's important to keep your code portable between platforms, whether you're writing a library or an application.

Predictably, most cross-platform issues come from Windows. Things just work differently there! But if you're careful, and follow some simple best practices, your code can run just as well on Windows systems.

Paths and URLs

On Windows, paths are constructed with backslashes instead of forward slashes. So if you do your directory manipulation

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

System Design Cheatsheet

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

Basic Steps

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?

Parser

/src/parser/spider_monkey_ast.ml: The type definitions for the AST. Tries to stay very close to ESTree
/src/parser/lexer_flow.mll: The ocamllex lexer logic
/src/parser/parser_flow.ml: The recursive descent JS parser

Inference

/src/typing/type_inference_js.ml: Contains the "entry point" for inference (Function called infer_ast).
/src/typing/statement.ml: Most of the inference logic (runs through the AST and generates the initial constraints)

Best practices for building Vim plugins

	"shove this in ~/.vim/nerdtree_plugin/grep_menuitem.vim

	" Add 'g' menu items to grep under selected directory.
	" 'g' : prompts the user to type search pattern under selected dir.
	" use parent directory if file is selected.
	" This uses ':grep'.
