This way i take variable inside dockerfile, from the file in my machine, and from environment in aws

React using state and props, Shopping Cart MVC 2019

React using state and props, Shopping Cart MVC 2019

I mean, the simplest example learning how to use the React state, and React props

( Clearly here i'm not using Redux, this is the next step, just to be clear )

React state of the App

React props of each React.Component Instance

So we can have list of products, and a shopping cart (list of items of products), adding and removing items.

The point is to learn how to pass action control over components, changing from state to new states on action events from components, to the Root App, and showing the change in the other affected Component.

running test sample puppeteer docker compose debian 9

Here we have a simple sample, to run puppeteer and check OK or NOT browsing uno site.

This is the way of code, set the timeout in the it().timeout(0), because mocha take 2 seconds.

install node modules globally in debian 9

Installing node modules globally in debian 9 The unix way, your user need to be part of staff group

educacion@family:~/src/docker17_puppeteer$ fgrep educacion /etc/group
staff:x:50:educacion
ssh:x:113:educacion
educacion:x:1000:

Now you have clean access to /usr/local, because you are part of staff group, it's the unix way ( try to not use sudo, not been part of sudo )

educacion@family:~/src/docker17_puppeteer$ npm set prefix /usr/local

educacion@family:~/src/docker17_puppeteer$ npm install -g jshint
/usr/local/bin/jshint -> /usr/local/lib/node_modules/jshint/bin/jshint
