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

First of all, this is not my brilliant effort to get react-native working on Windows, it is the collation of work by others, particularly @mqli and @Bernd Wessels. I've just summarised what worked for me.

If you would prefer to read what I've plagerised, head over to mqli's great gist

Disclaimer

The below is tested with react-native-cli 0.1.5, react-native 0.12.0 on Windows 10, node 4.1.1, and Android (physical Nexus 6 and AVD with API v22)
I hope this will all be redundant in a few weeks. Please comment on stuff that is now fixed and I will update this to keep it relevant.
Sprinkle a bit of YMMV around

Keep this github issue handy, it’s the bucket for all Windows/Linux related tricks to get RN working.

#Progress in C

This is in an example meant to present some ideas regarding command-line progress bars in C.

##Important parts

The main idea is to overwrite stdout with new information every time a particular step is reached. I accomplished this using the VT100 emulator hack from [this Stack Overflow answer][1]. In a nutshell, printing ^[[2K to stdout erases the current line, but it doesn't necessarily move the cursor to the start. Printing \r does that. Also, I decided I wanted to print a newline character after the progress indicator, but I need to get rid of that newline on the next print. That's what \b does: it inserts a backspace, deleting the last character printed.

Also important is the call to fflush, which will guarantee that the print operation completes and is visible before the program moves on to its next task (see [this Stack Overflow answer][2]).
