React Function Component で副作用(状態、ライフサイクル)を表現する
All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.
A number of methods in React are assumed to be "pure".
On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.
// Usage: | |
// <div> | |
// <GlobalKeyListner keyCode={13} handler={() => console.log('Enter')}/> | |
// </div> | |
export default class GlobalKeyListner extends React.Component { | |
type = 'keydown' | |
componentDidMount() { | |
const keyCode = this.props.keyCode | |
this._bound = (ev: SyntheticEvent) => { | |
if (ev.keyCode === keyCode) { |

There are a lot of ways to serve a Go HTTP application. The best choices depend on each use case. Currently nginx looks to be the standard web server for every new project even though there are other great web servers as well. However, how much is the overhead of serving a Go application behind an nginx server? Do we need some nginx features (vhosts, load balancing, cache, etc) or can you serve directly from Go? If you need nginx, what is the fastest connection mechanism? This are the kind of questions I'm intended to answer here. The purpose of this benchmark is not to tell that Go is faster or slower than nginx. That would be stupid.
So, these are the different settings we are going to compare:
http{ | |
index index.html; | |
server { | |
listen 80; | |
root /gocode/src/personalwebsiteapp; | |
server_name personal-website.com; |
from fabric.api import env, run, sudo, local, put | |
def production(): | |
"""Defines production environment""" | |
env.user = "deploy" | |
env.hosts = ['example.com',] | |
env.base_dir = "/var/www" | |
env.app_name = "app" | |
env.domain_name = "app.example.com" | |
env.domain_path = "%(base_dir)s/%(domain_name)s" % { 'base_dir':env.base_dir, 'domain_name':env.domain_name } |
